If lochia continues for more than 6 weeks, an ultrasound should be performed.

During the puerperium, which is the period of around 6 weeks after childbirth when the woman’s reproductive organs return to their normal state, lochia is the discharge of blood, mucous, and uterine tissue that occurs. It is expected to stop after 4-6 weeks. However, if it persists beyond this time, an ultrasound is necessary to investigate the possibility of retained products of conception.

Lochia refers to the discharge that is released from the vagina after childbirth. This discharge is composed of blood, mucous, and uterine tissue. It is a normal occurrence that can last for up to six weeks following delivery. During this time, the body is working to heal and recover from the physical changes that occurred during pregnancy and childbirth. It is important for new mothers to monitor their lochia and report any unusual changes or symptoms to their healthcare provider.

It is likely that the patient is experiencing placental abruption, which is a medical emergency. The severity of the abruption and the risks to both the mother and the baby determine the management approach. This patient has risk factors such as chronic hypertension and smoking. Steroids should be administered to assist in fetal lung development if the fetus is alive, less than 36 weeks, and not in distress. The patient’s vital signs are stable, but the volume of vaginal bleeding may not accurately reflect the severity of the bleed. The fetal status is assessed using a cardiotocograph, which indicates whether the fetus is receiving adequate blood and nutrients from the placenta. Expectant management is not appropriate, and intervention is necessary to increase the chances of a positive outcome. Immediate caesarean section is only necessary if the fetus is in distress or if the mother is experiencing significant blood loss. Vaginal delivery is only appropriate if the fetus has died in utero, which is not the case here.

Placental Abruption: Causes, Management, and Complications

Placental abruption is a condition where the placenta separates from the uterine wall, leading to maternal haemorrhage. The severity of the condition depends on the extent of the separation and the gestational age of the fetus. Management of placental abruption is crucial to prevent maternal and fetal complications.

If the fetus is alive and less than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, close observation, administration of steroids, and no tocolysis are recommended. The decision to deliver depends on the gestational age of the fetus. If the fetus is alive and more than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, vaginal delivery is recommended. If the fetus is dead, vaginal delivery should be induced.

Placental abruption can lead to various maternal complications, including shock, disseminated intravascular coagulation (DIC), renal failure, and postpartum haemorrhage (PPH). Fetal complications include intrauterine growth restriction (IUGR), hypoxia, and death. The condition is associated with a high perinatal mortality rate and is responsible for 15% of perinatal deaths.

In conclusion, placental abruption is a serious condition that requires prompt management to prevent maternal and fetal complications. Close monitoring and timely intervention can improve the prognosis for both the mother and the baby.

Folic Acid Supplementation in Pregnancy

Explanation: Folic acid supplementation is recommended for all women who are trying to conceive and during pregnancy to reduce the risk of neural tube defects and other congenital abnormalities. The recommended dose is 400 micrograms daily from the preconception period until the 12th week of gestation. However, women with certain high-risk factors, such as diabetes, a family history of neural tube defects, or obesity, are advised to take a higher dose of 5 mg daily from the preconception period until the 12th week of gestation. It is important to continue folic acid supplementation until the end of the first trimester to ensure proper formation of the brain and other major organs in the body. Side-effects of folic acid treatment may include abdominal distension, reduced appetite, nausea, and exacerbation of pernicious anaemia.

Understanding DIC: Symptoms and Diagnostic Tests

Disseminated intravascular coagulation (DIC) is a condition characterized by abnormal clotting and bleeding at the same time. This widespread disorder of clotting is caused by both thrombin and plasmin activation. Acutely, haemorrhage often occurs as the clotting factors are exhausted. The severity of the condition is variable but can lead to severe organ failure.

To diagnose DIC, doctors typically perform a full blood picture, coagulation screen, and a group-and-save test. Tests for DIC include elevated prothrombin time (PT) and activated partial thromboplastin time (aPTT). Platelet counts in DIC are typically low, especially in acute sepsis-associated DIC, but may be increased in malignancy-associated chronic DIC. Fibrinogen level is also tested, as it falls in DIC.

Symptoms of DIC include abnormal bleeding, such as from the gums or nose, and bruising easily. Patients may also experience organ failure, such as kidney or liver failure. Treatment for DIC typically involves addressing the underlying cause, such as sepsis or cancer, and providing supportive care, such as blood transfusions or medications to prevent clotting.

In summary, DIC is a serious condition that requires prompt diagnosis and treatment. If you experience symptoms of abnormal bleeding or organ failure, seek medical attention immediately.

Hyperemesis gravidarum is more likely to occur in women who are pregnant with multiple babies. Other factors that may increase the risk of HG include obesity, epilepsy, stress, and a family history of the condition. Treatment options may include corticosteroids like prednisolone, anti-emetic drugs such as ondansetron, and vitamins B6 and B12. While advanced maternal age can increase the risk of certain pregnancy complications, it has not been linked to an increased risk of HG. Similarly, having multiple previous pregnancies does not appear to increase the risk of HG, but a history of the condition in a previous pregnancy may be a risk factor.

Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy that occurs in around 1% of pregnancies and is most common between 8 and 12 weeks. It is associated with raised beta hCG levels and can be caused by multiple pregnancies, trophoblastic disease, hyperthyroidism, nulliparity, and obesity. Referral criteria for nausea and vomiting in pregnancy include continued symptoms with ketonuria and/or weight loss, a confirmed or suspected comorbidity, and inability to keep down liquids or oral antiemetics. The diagnosis of hyperemesis gravidarum requires the presence of 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance. Management includes first-line use of antihistamines and oral cyclizine or promethazine, with second-line options of ondansetron and metoclopramide. Admission may be needed for IV hydration. Complications can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth issues.

A woman at 12 weeks gestation is seeking Down syndrome screening. Although her age increases the likelihood of her fetus having Down’s syndrome, it will not affect the initial screening process. The standard screening method involves an ultrasound to evaluate nuchal translucency and serum testing to measure levels of β-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A). This combined screening can also detect Edward’s (trisomy 18) and Patau (trisomy 13) syndromes. The triple test, which includes α-fetoprotein, unconjugated oestriol, and β-hCG, is conducted between 15-20 weeks gestation to assess for Down’s syndrome. The quadruple test is also an option for women who have missed the window for combined antenatal screening. A biophysical profile, which evaluates fetal wellbeing through ultrasound detection of heart rate, breathing, movement, tone, and amniotic fluid volume, is used to determine the need for rapid induction of labor.

NICE updated guidelines on antenatal care in 2021, recommending the combined test for screening for Down’s syndrome between 11-13+6 weeks. The test includes nuchal translucency measurement, serum B-HCG, and pregnancy-associated plasma protein A (PAPP-A). The quadruple test is offered between 15-20 weeks for women who book later in pregnancy. Results are interpreted as either a ‘lower chance’ or ‘higher chance’ of chromosomal abnormalities. If a woman receives a ‘higher chance’ result, she may be offered a non-invasive prenatal screening test (NIPT) or a diagnostic test. NIPT analyzes cell-free fetal DNA in the mother’s blood and has high sensitivity and specificity for detecting chromosomal abnormalities. Private companies offer NIPT screening from 10 weeks gestation.

If a pregnant woman who is at least 20 weeks pregnant develops chickenpox, she should receive oral acyclovir treatment if she presents within 24 hours of the rash. Melissa, who is 33 weeks pregnant and has experienced prodromal symptoms, can be treated with oral acyclovir as she presented within the appropriate time frame. IV acyclovir is not typically necessary for pregnant women who have been in contact with chickenpox. To alleviate itchiness, it is reasonable to suggest using calamine lotion and antihistamines, but since Melissa is currently pregnant, she should also begin taking antiviral medications. Pain is not a significant symptom of chickenpox, and Melissa has not reported any pain, so recommending paracetamol is not the most effective course of action.

Chickenpox exposure in pregnancy can pose risks to both the mother and fetus, including fetal varicella syndrome. Post-exposure prophylaxis (PEP) with varicella-zoster immunoglobulin (VZIG) or antivirals should be given to non-immune pregnant women, with timing dependent on gestational age. If a pregnant woman develops chickenpox, specialist advice should be sought and oral acyclovir may be given if she is ≥ 20 weeks and presents within 24 hours of onset of the rash.

Management of Lactational Mastitis: Advice for Patients

Lactational mastitis is a common condition that affects breastfeeding women. It is important to manage this condition promptly to prevent complications such as breast abscesses. Here are some management options for lactational mastitis:

1. Advise her to continue breastfeeding and start empirical antibiotics: If the patient presents with lactational mastitis and has a nipple fissure, it is suggestive of an infective cause. In this case, the patient should be reassured, asked to continue breastfeeding, offered adequate analgesia, and started on empirical antibiotics.

2. Reassure the patient, ask her to continue expressing milk and review if there is no improvement in two days: If there is no evidence of infection, reassurance and advice to continue breastfeeding, as well as simple analgesia, are a good first management option. However, if symptoms do not improve in 24 hours, then there is an indication for starting empirical antibiotics.

3. Admit the patient to hospital for intravenous antibiotics and drainage: Admission is advisable for intravenous antibiotics and drainage if oral antibiotics fail to improve symptoms, the patient develops sepsis, or there is evidence of the development of a breast abscess.

4. Advise her to continue breastfeeding and send a breast milk culture and treat if positive: A breast milk culture should be sent before starting antibiotics, but in this case, given the patient fulfils the criteria for starting empirical treatment, you should not delay antibiotic therapy until the breast milk culture is back.

5. Reassure the patient, advise her to continue breastfeeding and offer simple analgesia: Reassurance, advice to continue breastfeeding, and simple analgesia are offered to women who first present with lactational mastitis. If symptoms do not improve after three days, there is an indication to offer empirical antibiotics.

In conclusion, lactational mastitis should be managed promptly to prevent complications. Patients should be advised to continue breastfeeding, offered adequate analgesia, and started on empirical antibiotics if necessary. If symptoms do not improve, further management options should be considered.

Gestational diabetes can be diagnosed if the patient has a fasting glucose level of 5.6 mmol/L or higher, or a 2-hour glucose level of 7.8 mmol/L or higher. This diagnosis is typically made during an oral glucose tolerance test around 24 weeks into the pregnancy for women with risk factors, such as a high BMI or a first-degree relative with diabetes mellitus. In this patient’s case, she was diagnosed with gestational diabetes mellitus during her first pregnancy due to her risk factors. Therefore, the correct answer is a fasting plasma glucose level above 5.6 mmol/L. It is important to note that a 2-hour glucose level above 5.6 mmol/L is not diagnostic of gestational diabetes mellitus, and random plasma glucose tests are not used for diagnosis. Glucose targets for women with gestational diabetes mellitus include a 2-hour glucose level of 6.4 mmol/L after mealtime and a 1-hour glucose level of 7.8 mmol/L after mealtime.

Gestational diabetes is a common medical disorder affecting around 4% of pregnancies. Risk factors include a high BMI, previous gestational diabetes, and family history of diabetes. Screening is done through an oral glucose tolerance test, and diagnostic thresholds have recently been updated. Management includes self-monitoring of blood glucose, diet and exercise advice, and medication if necessary. For pre-existing diabetes, weight loss and insulin are recommended, and tight glycemic control is important. Targets for self-monitoring include fasting glucose of 5.3 mmol/l and 1-2 hour post-meal glucose levels.

The initial investigation for preterm prelabour rupture of the membranes is a thorough speculum examination to check for the accumulation of amniotic fluid in the posterior vaginal vault. It is recommended to avoid bimanual examination to minimize the risk of infection. While cardiotocography can be used to assess foetal wellbeing, it is not the preferred first-line investigation. Foetal blood sampling is not the recommended initial investigation due to the potential risks of infection and miscarriage.

Preterm prelabour rupture of the membranes (PPROM) is a condition that occurs in approximately 2% of pregnancies, but it is responsible for around 40% of preterm deliveries. This condition can lead to various complications, including prematurity, infection, and pulmonary hypoplasia in the fetus, as well as chorioamnionitis in the mother. To confirm PPROM, a sterile speculum examination should be performed to check for pooling of amniotic fluid in the posterior vaginal vault. However, digital examination should be avoided due to the risk of infection. If pooling of fluid is not observed, testing the fluid for placental alpha microglobulin-1 protein (PAMG-1) or insulin-like growth factor binding protein-1 is recommended. Ultrasound may also be useful to show oligohydramnios.

The management of PPROM involves admission and regular observations to ensure that chorioamnionitis is not developing. Oral erythromycin should be given for ten days, and antenatal corticosteroids should be administered to reduce the risk of respiratory distress syndrome. Delivery should be considered at 34 weeks of gestation, but there is a trade-off between an increased risk of maternal chorioamnionitis and a decreased risk of respiratory distress syndrome as the pregnancy progresses. PPROM is a serious condition that requires prompt diagnosis and management to minimize the risk of complications for both the mother and the fetus.

What is the recommended prophylaxis for Rhesus sensitisation in a Rhesus negative mother with antepartum haemorrhage?

Antepartum haemorrhage increases the risk of Rhesus sensitisation and Rhesus disease of the newborn in subsequent pregnancies due to fetomaternal haemorrhage (FMH). The correct approach is to administer one dose of anti-D immunoglobulin immediately, followed by a Kleihauer test. This test detects fetal cells in the maternal circulation and estimates the volume of FMH, allowing for the calculation of additional anti-D immunoglobulin. While routine prophylaxis at 28 weeks should still be given, there is no such thing as an anti-D immunoglobulin infusion. These recommendations are based on the British Committee for Standards in Haematology guidelines for the prevention of haemolytic disease of the fetus and newborn.

Rhesus negative pregnancies can lead to the formation of anti-D IgG antibodies in the mother if she delivers a Rh +ve child, which can cause haemolysis in future pregnancies. Prevention involves testing for D antibodies and giving anti-D prophylaxis to non-sensitised Rh -ve mothers at 28 and 34 weeks. Anti-D immunoglobulin should be given within 72 hours in various situations. Tests should be done on all babies born to Rh -ve mothers, and affected fetuses may experience various complications and require treatment such as transfusions and UV phototherapy.

Postnatal Check: What to Expect from Your GP

After giving birth, it is important to have a postnatal check with your GP to ensure that you are recovering well and to address any concerns you may have. Here are some of the things you can expect during your 6-week postnatal check:

Performing a Smear Test if Delayed Because of Pregnancy
If you were due for a routine smear test during pregnancy, it will be deferred until at least three months post-delivery. This is to avoid misinterpreting cell changes that occur during pregnancy and to identify any precancerous changes in the cells of the cervix.

Assessment of Mood
Your GP will assess your mood and any psychological disturbance you may be experiencing. This is an opportunity to screen for postnatal depression and identify any need for additional support.

Assessing Surgical Wound Healing and/or the Perineum if Required
Depending on the mode of delivery, your GP will assess the healing of any surgical wounds or perineal tears. They will also check for signs of infection or abnormal healing.

Blood Pressure Reading
Your GP will perform a blood pressure reading, especially if you had hypertension during pregnancy. Urinalysis may also be performed if you had pre-eclampsia or signs of a urinary tract infection.

Discussion of Contraceptive Options
Your GP will discuss family planning and the need for additional contraception, as required. This is important to prevent unintended pregnancies, especially if you are not exclusively breastfeeding.

Overall, the 6-week postnatal check is an important part of your recovery process and ensures that you receive the necessary care and support during this time.

Placenta praevia is characterized by painless and bright red bleeding, while placental abruption is accompanied by dark red bleeding and pain. The history of previous bleeding also suggests placenta praevia. Vasa praevia may also cause painless vaginal bleeding, but fetal bradycardia and membrane rupture are expected symptoms.

Understanding Placenta Praevia

Placenta praevia is a condition where the placenta is located wholly or partially in the lower uterine segment. It is a relatively rare condition, with only 5% of women having a low-lying placenta when scanned at 16-20 weeks gestation. However, the incidence at delivery is only 0.5%, as most placentas tend to rise away from the cervix.

There are several factors associated with placenta praevia, including multiparity, multiple pregnancy, and embryos implanting on a lower segment scar from a previous caesarean section. Clinical features of placenta praevia include shock in proportion to visible loss, no pain, a non-tender uterus, abnormal lie and presentation, and a usually normal fetal heart. Coagulation problems are rare, and small bleeds may occur before larger ones.

Diagnosis of placenta praevia should not involve digital vaginal examination before an ultrasound, as this may provoke severe haemorrhage. The condition is often picked up on routine 20-week abdominal ultrasounds, but the Royal College of Obstetricians and Gynaecologists recommends the use of transvaginal ultrasound for improved accuracy and safety. Placenta praevia is classified into four grades, with grade IV being the most severe, where the placenta completely covers the internal os.

In summary, placenta praevia is a rare condition that can have serious consequences if not diagnosed and managed appropriately. It is important for healthcare professionals to be aware of the associated factors and clinical features, and to use appropriate diagnostic methods for accurate grading and management.

In the case of a small placental abruption without signs of foetal distress and a gestational age of less than 36 weeks, the recommended management is to admit the patient and administer steroids. While vitamin K can aid in blood clotting, it is not the optimal choice in this situation. A caesarean section is not immediately necessary as the foetus is not in distress and is under 36 weeks. Antibiotics are not indicated as there are no signs of infection and the patient is not experiencing a fever. Continuous monitoring with CTG for 24 hours is not necessary if the foetus is not displaying any distress on initial presentation and the mother has not reported a decrease in foetal movements.

Placental Abruption: Causes, Management, and Complications

Placental abruption is a condition where the placenta separates from the uterine wall, leading to maternal haemorrhage. The severity of the condition depends on the extent of the separation and the gestational age of the fetus. Management of placental abruption is crucial to prevent maternal and fetal complications.

If the fetus is alive and less than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, close observation, administration of steroids, and no tocolysis are recommended. The decision to deliver depends on the gestational age of the fetus. If the fetus is alive and more than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, vaginal delivery is recommended. If the fetus is dead, vaginal delivery should be induced.

Placental abruption can lead to various maternal complications, including shock, disseminated intravascular coagulation (DIC), renal failure, and postpartum haemorrhage (PPH). Fetal complications include intrauterine growth restriction (IUGR), hypoxia, and death. The condition is associated with a high perinatal mortality rate and is responsible for 15% of perinatal deaths.

In conclusion, placental abruption is a serious condition that requires prompt management to prevent maternal and fetal complications. Close monitoring and timely intervention can improve the prognosis for both the mother and the baby.

Breastfeeding is generally safe with most anti-epileptic drugs, including Lamotrigine which is commonly prescribed for seizures. It is a preferred option for women as it does not affect their ability to bear children. However, Carbimazole and Diazepam active metabolite can be passed on to the baby through breast milk and should be avoided. Isotretinoin effect on breastfed infants is not well studied, but oral retinoids should generally be avoided while breastfeeding.

Pregnancy and breastfeeding can be a concern for women with epilepsy. It is generally recommended that women continue taking their medication during pregnancy, as the risks of uncontrolled seizures outweigh the potential risks to the fetus. However, it is important for women to take folic acid before pregnancy to reduce the risk of neural tube defects. The use of antiepileptic medication during pregnancy can increase the risk of congenital defects, but this risk is still relatively low. It is recommended to aim for monotherapy and there is no need to monitor drug levels. Sodium valproate is associated with neural tube defects, while carbamazepine is considered the least teratogenic of the older antiepileptics. Phenytoin is associated with cleft palate, and lamotrigine may require a dose increase during pregnancy. Breastfeeding is generally safe for mothers taking antiepileptics, except for barbiturates. Pregnant women taking phenytoin should be given vitamin K in the last month of pregnancy to prevent clotting disorders in the newborn.

A warning has been issued about the use of sodium valproate during pregnancy and in women of childbearing age. New evidence suggests a significant risk of neurodevelopmental delay in children following maternal use of this medication. Therefore, it should only be used if clearly necessary and under specialist neurological or psychiatric advice. It is important for women with epilepsy to discuss their options with their healthcare provider and make informed decisions about their treatment during pregnancy and breastfeeding.

Safe Pain Relief Options for Breastfeeding Mothers: A Guide to Medications

Breastfeeding mothers often experience pain and discomfort, and it is important to know which pain relief options are safe to use while nursing. Paracetamol and ibuprofen are considered safe and can be used as first-line medication for analgesia. Codeine and other opiates can be used sparingly as third-line medication, but caution must be taken as some women may be slow metabolizers and it can cause drowsiness and respiratory depression in the infant. Aspirin is contraindicated due to the risk of Reye’s disease and other side-effects. Naproxen is generally safe, but paracetamol and ibuprofen should be the mainstay of analgesia. Tramadol can be used with caution and should be prescribed by a specialist. It is important to advise the woman on the safe use of medication and to monitor for any signs of toxicity in the infant.

Referral to a maternal fetal medicine unit is recommended if fetal movements have not been felt by 24 weeks, as reduced movements can be a sign of fetal distress and hypoxia. While most women feel their babies move around 18-20 weeks, it can happen earlier in some cases. Although singular episodes of reduced movements may not be harmful, they can also indicate stillbirths and restricted growth. The absence of movements is particularly concerning and requires further investigation. The RCOG has set the 24 week cut off as a guideline.

Understanding Reduced Fetal Movements

Introduction:
Reduced fetal movements can indicate fetal distress and are a response to chronic hypoxia in utero. This can lead to stillbirth and fetal growth restriction. It is believed that placental insufficiency may also be linked to reduced fetal movements.

Physiology:
Quickening is the first onset of fetal movements, which usually occurs between 18-20 weeks gestation and increases until 32 weeks gestation. Multiparous women may experience fetal movements sooner. Fetal movements should not reduce towards the end of pregnancy. There is no established definition for what constitutes reduced fetal movements, but less than 10 movements within 2 hours (in pregnancies past 28 weeks gestation) is an indication for further assessment.

Epidemiology:
Reduced fetal movements affect up to 15% of pregnancies, with 3-5% of pregnant women having recurrent presentations with RFM. Fetal movements should be established by 24 weeks gestation.

Risk factors for reduced fetal movements:
Posture, distraction, placental position, medication, fetal position, body habitus, amniotic fluid volume, and fetal size can all affect fetal movement awareness.

Investigations:
Fetal movements are usually based on maternal perception, but can also be objectively assessed using handheld Doppler or ultrasonography. Investigations are dependent on gestation at onset of RFM. If concern remains, despite normal CTG, urgent (within 24 hours) ultrasound can be used.

Prognosis:
Reduced fetal movements can represent fetal distress, but in 70% of pregnancies with a single episode of reduced fetal movement, there is no onward complication. However, between 40-55% of women who suffer from stillbirth experience reduced fetal movements prior to diagnosis. Recurrent RFM requires further investigations to consider structural or genetic fetal abnormalities.

The recommended course of action for a patient in early labour with a transverse foetal lie and intact amniotic sac is to offer external cephalic version (ECV) before considering other management options. Conservative management is not appropriate as it poses a high risk of maternal and foetal death. Offering an elective caesarean section is also not the first choice, as ECV should be attempted first. An immediate caesarean section is not necessary if there are no contraindications to ECV.

Understanding Transverse Lie in Foetal Presentation

Foetal lie refers to the position of the foetus in relation to the longitudinal axis of the uterus. There are three types of foetal lie: longitudinal, oblique, and transverse. Transverse lie is a rare abnormal foetal presentation where the foetal longitudinal axis is perpendicular to the long axis of the uterus. This means that the foetal head is on the lateral side of the pelvis, and the buttocks are opposite. Transverse lie is more common in women who have had previous pregnancies, have fibroids or other pelvic tumours, are pregnant with twins or triplets, have prematurity, polyhydramnios, or foetal abnormalities.

Transverse lie can be detected during routine antenatal appointments through abdominal examination or ultrasound scan. Complications of transverse lie include preterm rupture membranes, cord-prolapse, and compound presentation. Management options for transverse lie depend on the gestational age of the foetus. Before 36 weeks gestation, no management is required as most foetuses will spontaneously move into longitudinal lie during pregnancy. After 36 weeks gestation, active management through external cephalic version (ECV) or elective caesarian section is necessary. ECV should be offered to all women who would like a vaginal delivery, while caesarian section is the management for women who opt for it or if ECV is unsuccessful or contraindicated. The decision to perform caesarian section over ECV will depend on various factors, including the risks to the mother and foetus, the patient’s preference, and co-morbidities.

Management of Parvovirus B19 Infection in Pregnancy

Parvovirus B19 infection in pregnancy can have detrimental effects on the developing fetus. Therefore, it is important to manage the infection appropriately. Here are some key steps to take:

1. Arrange urgent referral to a specialist Fetal Medicine Unit (to be seen within 4 weeks) and do serial ultrasound scans to monitor fetal growth and assess for complications.

2. Arrange fetal blood sampling and transfusion if there is an indication of fetal infection.

3. Advise the woman to avoid going to work and contact with other pregnant women for at least five days to prevent transmission of the infection.

4. Give one dose of varicella-zoster virus (VZV) immunoglobulin and review in five days if the woman was exposed to chickenpox and is not immune to VZV.

5. Suggest paracetamol as required and plenty of fluids at present for the management of myalgia and arthralgia associated with the infection.

It is important to confirm the diagnosis of parvovirus B19 infection with serology on at least two separate samples and to monitor the woman and fetus closely for potential complications. With appropriate management, the risk of fetal morbidity and mortality can be reduced.

The primary treatment for nausea and vomiting during pregnancy, including hyperemesis gravidarum, is antihistamines.

Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy that occurs in around 1% of pregnancies and is most common between 8 and 12 weeks. It is associated with raised beta hCG levels and can be caused by multiple pregnancies, trophoblastic disease, hyperthyroidism, nulliparity, and obesity. Referral criteria for nausea and vomiting in pregnancy include continued symptoms with ketonuria and/or weight loss, a confirmed or suspected comorbidity, and inability to keep down liquids or oral antiemetics. The diagnosis of hyperemesis gravidarum requires the presence of 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance. Management includes first-line use of antihistamines and oral cyclizine or promethazine, with second-line options of ondansetron and metoclopramide. Admission may be needed for IV hydration. Complications can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth issues.

Women who have recently given birth, whether they are breastfeeding or not, can begin taking the progesterone-only pill at any time. However, for this patient who is only 2 days postpartum, it is recommended to prescribe the progesterone-only pill as it does not contain estrogen and is less likely to affect milk production. Additionally, it does not increase the risk of venous thromboembolism, which is a concern for postpartum women until 21-28 days after giving birth. The combined oral contraceptive pill should be avoided until 21 days postpartum due to the risk of thrombosis and reduced breast milk production. The patient cannot resume her previous contraceptives at this time. While an intrauterine device can be inserted during a caesarean section, it is advisable to wait 4-6 weeks postpartum before having it inserted vaginally. It is incorrect to tell the patient that she cannot use any contraception if she wishes to breastfeed, as the progesterone-only pill has been shown to have minimal effect on milk production in breastfeeding women.

After giving birth, women need to use contraception after 21 days. The progesterone-only pill (POP) can be started at any time postpartum, according to the FSRH. Additional contraception should be used for the first two days after day 21. A small amount of progesterone enters breast milk, but it is not harmful to the infant. On the other hand, the combined oral contraceptive pill (COCP) is absolutely contraindicated (UKMEC 4) if breastfeeding is less than six weeks post-partum. If breastfeeding is between six weeks and six months postpartum, it is a UKMEC 2. The COCP may reduce breast milk production in lactating mothers. It should not be used in the first 21 days due to the increased venous thromboembolism risk post-partum. After day 21, additional contraception should be used for the first seven days. The intrauterine device or intrauterine system can be inserted within 48 hours of childbirth or after four weeks.

The lactational amenorrhoea method (LAM) is 98% effective if the woman is fully breastfeeding (no supplementary feeds), amenorrhoeic, and less than six months post-partum. It is important to note that an inter-pregnancy interval of less than 12 months between childbirth and conceiving again is associated with an increased risk of preterm birth, low birth weight, and small for gestational age babies.

Pregnant women whose blood pressure is equal to or greater than 160/110 mmHg are likely to be admitted and monitored. In this case, the patient is hypertensive at 35 weeks of gestation. While pre-eclampsia was previously defined as hypertension and proteinuria during pregnancy, the current diagnosis includes hypertension and any end-organ damage. Although the patient feels well, she should be admitted to the local maternity unit for further investigation as her blood pressure exceeds the threshold. Urgent delivery of the infant should not be arranged unless the mother is unstable or there is fetal distress. The presence of nitrites in the urine dipstick is not a significant concern, and delaying further investigation for a week is not appropriate. Prescribing antibiotics for asymptomatic patients with positive nitrites and no leukocytes in the urine is incorrect management and does not address the hypertension. Continuing with midwife-led care without further investigation for two weeks could lead to the development of pre-eclampsia or eclamptic seizure, which is dangerous for both mother and fetus.

Pre-eclampsia is a condition that occurs during pregnancy and is characterized by high blood pressure, proteinuria, and edema. It can lead to complications such as eclampsia, neurological issues, fetal growth problems, liver involvement, and cardiac failure. Severe pre-eclampsia is marked by hypertension, proteinuria, headache, visual disturbances, and other symptoms. Risk factors for pre-eclampsia include hypertension in a previous pregnancy, chronic kidney disease, autoimmune disease, diabetes, chronic hypertension, first pregnancy, and age over 40. Aspirin may be recommended for women with high or moderate risk factors. Treatment involves emergency assessment, admission for observation, and medication such as labetalol, nifedipine, or hydralazine. Delivery of the baby is the most important step in management, with timing depending on the individual case.

When managing placental abruption in a case where the fetus is alive, less than 36 weeks old, and not displaying any signs of distress, the appropriate course of action is to admit the patient and administer steroids. Admitting the patient is necessary for monitoring and providing necessary care. Steroids are given to aid in the maturation of fetal lungs. It is recommended to deliver the baby at 37-38 weeks due to the increased risk of stillbirth. Tocolytics are not routinely given due to their controversial nature and potential for maternal cardiovascular side effects. Discharging the patient with safety netting is not appropriate as the patient is symptomatic. Activating the major haemorrhage protocol, calling 2222, and performing an emergency caesarean section are not the most suitable options as the patient is not hypotensive and there are no signs of fetal distress.

Placental Abruption: Causes, Management, and Complications

Placental abruption is a condition where the placenta separates from the uterine wall, leading to maternal haemorrhage. The severity of the condition depends on the extent of the separation and the gestational age of the fetus. Management of placental abruption is crucial to prevent maternal and fetal complications.

If the fetus is alive and less than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, close observation, administration of steroids, and no tocolysis are recommended. The decision to deliver depends on the gestational age of the fetus. If the fetus is alive and more than 36 weeks, immediate caesarean delivery is recommended if there is fetal distress. If there is no fetal distress, vaginal delivery is recommended. If the fetus is dead, vaginal delivery should be induced.

Placental abruption can lead to various maternal complications, including shock, disseminated intravascular coagulation (DIC), renal failure, and postpartum haemorrhage (PPH). Fetal complications include intrauterine growth restriction (IUGR), hypoxia, and death. The condition is associated with a high perinatal mortality rate and is responsible for 15% of perinatal deaths.

In conclusion, placental abruption is a serious condition that requires prompt management to prevent maternal and fetal complications. Close monitoring and timely intervention can improve the prognosis for both the mother and the baby.

Management of Nausea and Vomiting in Pregnancy: Medications and Considerations

Nausea and vomiting in pregnancy are common and can range from mild to severe. Conservative measures such as dietary changes and ginger can be effective for mild symptoms, but oral anti-emetics are recommended for more severe cases. First-line medications include promethazine, cyclizine, and phenothiazines. If these fail, second-line medications such as ondansetron and metoclopramide may be prescribed. Severe cases may require hospital admission, parenteral anti-emetics, and fluid resuscitation. Thiamine is given to all women admitted with severe vomiting. Steroid treatments such as hydrocortisone should be reserved for specialist use. It is important to monitor for side-effects and consider referral to secondary care if necessary.

The correct stage of labour for a woman with a cervix that is just beginning to ripen and dilate is the latent phase of the 1st stage. This stage is characterized by a cervix dilation of 0-3 cm. The active phase of the 1st stage, which is characterized by a cervix dilation of 3-10 cm and more regular contractions, is not applicable in this scenario. The active 2nd stage is also not a descriptive stage of labour, as it only refers to the general stage that ends with the expulsion of the foetus.

Labour is divided into three stages, with the first stage beginning from the onset of true labour until the cervix is fully dilated. This stage is further divided into two phases: the latent phase and the active phase. The latent phase involves dilation of the cervix from 0-3 cm and typically lasts around 6 hours. The active phase involves dilation from 3-10 cm and progresses at a rate of approximately 1 cm per hour. In primigravidas, this stage can last between 10-16 hours.

During this stage, the baby’s presentation is important to note. Approximately 90% of babies present in the vertex position, with the head entering the pelvis in an occipito-lateral position. The head typically delivers in an occipito-anterior position.

Common Tumor Markers and their Clinical Significance

Beta human chorionic gonadotropin (β-HCG)
β-HCG levels are monitored in cases of molar pregnancy, which can present with morning sickness and symptoms of hyperthyroidism due to high levels of HCG. Monitoring levels of β-HCG is important to ensure that no fetal tissue remains after treatment to minimise the risk of developing choriocarcinoma or a persistent mole.

Alpha fetoprotein (AFP)
AFP is a marker used to screen for neural tube defects, hepatocellular carcinoma and endodermal sinus tumours.

CA-125
CA-125 is a marker of ovarian malignancy. Although it is used to monitor response to chemotherapy and tumour recurrence, it has not been widely used as a screening tool.

Lactate dehydrogenase (LDH)
Increased LDH is strongly associated with dysgerminomas.

Oestriol
Urine unconjugated oestriol is measured as part of the quadruple screen for trisomy 21. Low levels of oestriol are suggestive of Down syndrome.

Understanding Tumor Markers and their Clinical Implications

While many symptoms experienced during pregnancy are normal and not a cause for concern, it is important to be aware of symptoms that may indicate a medical issue, such as dysuria.

Dysuria, or painful urination, can be a sign of a urinary tract infection (UTI), which should be treated promptly during any stage of pregnancy. UTIs have been linked to premature birth, as the inflammation caused by the infection can irritate the cervix and trigger preterm labor.

Fatigue during pregnancy is a common experience and can have multiple causes. In the third trimester, it is considered normal. Lower back pain is also a common symptom, caused by the hormone relaxin increasing laxity in the sacroiliac joints and the added mechanical strain of pregnancy.

Nausea and vomiting are most commonly experienced in the first trimester, but can still occur throughout pregnancy and are generally considered normal.

Minor Symptoms of Pregnancy

During pregnancy, women may experience minor symptoms that are common and not usually a cause for concern. These symptoms may include nausea and vomiting, tiredness, and musculoskeletal pains. Nausea and vomiting, commonly known as morning sickness, can occur at any time of the day and may last throughout the first trimester. Tiredness is also a common symptom, especially during the first and third trimesters. Musculoskeletal pains, such as back pain and pelvic pain, may also occur due to the changes in the body’s structure and weight distribution. While these symptoms may be uncomfortable, they are typically manageable and can be relieved with rest, exercise, and proper nutrition. It is important to consult with a healthcare provider if these symptoms become severe or persistent.

To prevent neural tube defects, it is recommended that women who are at risk start taking folic acid before conception. The standard dose of 0.4mg should be taken daily until 13 weeks of pregnancy. It is important to start taking folic acid before conception because the neural tube is formed within the first 28 days of embryo development. If a woman waits until after her missed period, any defects may already be present. Women who are at an increased risk of neural tube defects, such as those who have had a previous child with NTD, diabetes mellitus, are on antiepileptic medication, are obese (with a body mass index over 30 kg/m²), are HIV positive and taking co-trimoxazole, or have sickle cell disease, should take an increased dose of 5mg folic acid.

Folic Acid: Importance, Deficiency, and Prevention

Folic acid is a vital nutrient that is converted to tetrahydrofolate (THF) in the body. It is found in green, leafy vegetables and plays a crucial role in the transfer of 1-carbon units to essential substrates involved in the synthesis of DNA and RNA. However, certain factors such as phenytoin, methotrexate, pregnancy, and alcohol excess can cause a deficiency in folic acid. This deficiency can lead to macrocytic, megaloblastic anemia and neural tube defects.

To prevent neural tube defects during pregnancy, it is recommended that all women take 400mcg of folic acid until the 12th week of pregnancy. Women at higher risk of conceiving a child with a neural tube defect should take 5mg of folic acid from before conception until the 12th week of pregnancy. Women are considered higher risk if they or their partner has a neural tube defect, they have had a previous pregnancy affected by a neural tube defect, or they have a family history of a neural tube defect. Additionally, women with certain medical conditions such as coeliac disease, diabetes, or thalassaemia trait, or those taking antiepileptic drugs, or who are obese (BMI of 30 kg/m2 or more) are also considered higher risk.

In summary, folic acid is an essential nutrient that plays a crucial role in DNA and RNA synthesis. Deficiency in folic acid can lead to serious health consequences, including neural tube defects. However, taking folic acid supplements during pregnancy can prevent these defects and ensure a healthy pregnancy.

Physiological Changes in Pregnancy

Pregnancy is a time of significant physiological changes in a woman’s body. These changes are mainly driven by progesterone rather than oestrogen. One of the changes is vasodilation, which leads to a drop in blood pressure initially, but it normalizes by term. However, an increase in heart rate and stroke volume leads to an increase in cardiac output.

Another change is a decrease in lower oesophageal sphincter tone and vascular resistance, which causes a drop in blood pressure. This decrease occurs over the first trimester but starts to increase to normal by term. Oestrogen is responsible for this change, and it also causes symptoms of reflux.

Pregnancy also causes a mild anaemia due to a drop in red cell volume. However, this is a dilutional anaemia caused by an increase in plasma volume. Additionally, there is an increase in clotting factors II, VII, IX, and X, which makes pregnancy a hypercoagulable state.

The functional residual capacity (FRC) increases in pregnancy, leading to more rapid breathing and smaller tidal volumes. This decrease in FRC means that oxygen reserve is less in pregnant women. Minute ventilation increases due to increased oxygen consumption and increased CO2 production. This is by increased tidal volume rather than respiratory rate.

Finally, the glomerular filtration rate (GFR) decreases secondary to progesterone, facilitating an increase in fluid retention and an increase in plasma volume. However, there is also an increase in aldosterone, which acts on the kidneys producing water and sodium retention, therefore causing an increase in plasma volume.

In conclusion, pregnancy causes significant physiological changes in a woman’s body, which are mainly driven by progesterone. These changes affect various systems, including the cardiovascular, respiratory, and renal systems.

According to NICE guidelines, women who are due for routine cervical screening should wait until 12 weeks after giving birth. If a woman has had an abnormal smear in the past and becomes pregnant, she should seek specialist advice. If there are no contraindications, such as a low-lying placenta, a cervical smear can be performed during the middle trimester of pregnancy. It is crucial to encourage women to participate in regular cervical screening.

Cervical Cancer Screening in the UK

Cervical cancer screening is a well-established program in the UK that aims to detect pre-malignant changes in the cervix. This program is estimated to prevent 1,000-4,000 deaths per year. However, it should be noted that around 15% of cervical adenocarcinomas are frequently undetected by screening.

The screening program has evolved significantly in recent years. Initially, smears were examined for signs of dyskaryosis, which may indicate cervical intraepithelial neoplasia. However, the introduction of HPV testing allowed for further risk stratification, and the NHS has now moved to an HPV first system. This means that a sample is tested for high-risk strains of human papillomavirus (hrHPV) first, and cytological examination is only performed if this is positive.

All women between the ages of 25-64 years are offered a smear test. Women aged 25-49 years are screened every three years, while those aged 50-64 years are screened every five years. However, cervical screening cannot be offered to women over 64. In Scotland, screening is offered from 25-64 every five years.

In special situations, cervical screening in pregnancy is usually delayed until three months post-partum, unless there are missed screenings or previous abnormal smears. Women who have never been sexually active have a very low risk of developing cervical cancer and may wish to opt-out of screening.

It is recommended to take a cervical smear around mid-cycle, although there is limited evidence to support this advice. Overall, the UK’s cervical cancer screening program is an essential tool in preventing cervical cancer and promoting women’s health.
