In the case of umbilical cord prolapse, the priority is to limit compression on the cord and reduce the chance of cord vasospasm. This can be achieved by pushing any presenting part of the baby back into the uterus, putting the mother on all fours, and retrofilling the bladder with saline. In addition, warm damp towels can be placed over the cord to limit handling. It is important to note that this is a complex emergency that requires immediate attention, as it can lead to foetal bradycardia and limit the oxygen supply to the baby. In this scenario, a category 1 Caesarean section would be necessary, as the pathological CTG demands it. Delivering the baby as breech immediately is not recommended, as it is a high-risk strategy that can lead to morbidity and mortality. IM corticosteroids are indicated for premature rupture of membranes, but the immediate priority is to deal with the emergency. McRobert’s manoeuvre is not appropriate in this case, as it is used to correct shoulder dystocia, which is not the issue at hand.

Understanding Umbilical Cord Prolapse

Umbilical cord prolapse is a rare but serious complication that can occur during delivery. It happens when the umbilical cord descends ahead of the presenting part of the fetus, which can lead to compression or spasm of the cord. This can cause fetal hypoxia and potentially irreversible damage or death. Certain factors increase the risk of cord prolapse, such as prematurity, multiparity, polyhydramnios, twin pregnancy, cephalopelvic disproportion, and abnormal presentations like breech or transverse lie.

Around half of all cord prolapses occur when the membranes are artificially ruptured. Diagnosis is usually made when the fetal heart rate becomes abnormal and the cord is palpable vaginally or visible beyond the introitus. Cord prolapse is an obstetric emergency that requires immediate management. The presenting part of the fetus may be pushed back into the uterus to avoid compression, and the cord should be kept warm and moist to prevent vasospasm. The patient may be asked to go on all fours or assume the left lateral position until preparations for an immediate caesarian section have been carried out. Tocolytics may be used to reduce uterine contractions, and retrofilling the bladder with saline can help elevate the presenting part. Although caesarian section is the usual first-line method of delivery, an instrumental vaginal delivery may be possible if the cervix is fully dilated and the head is low.

In conclusion, umbilical cord prolapse is a rare but serious complication that requires prompt recognition and management. Understanding the risk factors and appropriate interventions can help reduce the incidence of fetal mortality associated with this condition.

It should be noted that the woman already had hypertension before becoming pregnant. Blood pressure issues related to pregnancy, such as pre-eclampsia or pregnancy-induced hypertension, typically do not occur until after 20 weeks of gestation. The elevated blood pressure readings obtained through ambulatory monitoring rule out the possibility of white-coat hypertension. It is important to note that the term pre-existing hypertension is used instead of essential hypertension, as high blood pressure in a woman of this age is uncommon and may indicate secondary hypertension.

Hypertension during pregnancy is a common occurrence that requires careful management. In normal pregnancies, blood pressure tends to decrease in the first trimester and then gradually increase to pre-pregnancy levels by term. However, in cases of hypertension during pregnancy, the systolic blood pressure is usually above 140 mmHg or the diastolic blood pressure is above 90 mmHg. Additionally, an increase of more than 30 mmHg systolic or 15 mmHg diastolic from the initial readings may also indicate hypertension.

There are three categories of hypertension during pregnancy: pre-existing hypertension, pregnancy-induced hypertension (PIH), and pre-eclampsia. Pre-existing hypertension refers to a history of hypertension before pregnancy or elevated blood pressure before 20 weeks gestation. PIH occurs in the second half of pregnancy and resolves after birth. Pre-eclampsia is characterized by hypertension and proteinuria, and may also involve edema.

The management of hypertension during pregnancy involves the use of antihypertensive medications such as labetalol, nifedipine, and hydralazine. In cases of pre-existing hypertension, ACE inhibitors and angiotensin II receptor blockers should be stopped immediately and alternative medications should be prescribed. Women who are at high risk of developing pre-eclampsia should take aspirin from 12 weeks until the birth of the baby. It is important to carefully monitor blood pressure and proteinuria levels during pregnancy to ensure the health of both the mother and the baby.

The administration of magnesium should be initiated in women who are at high risk of severe pre-eclampsia or those who have eclampsia. It is important to continue the treatment for 24 hours after delivery or the last seizure, whichever occurs later. Therefore, the correct answer is 24 hours after the last seizure.

Understanding Eclampsia and its Treatment

Eclampsia is a condition that occurs when seizures develop in association with pre-eclampsia, a pregnancy-induced hypertension that is characterized by proteinuria and occurs after 20 weeks of gestation. To prevent seizures in patients with severe pre-eclampsia and treat seizures once they develop, magnesium sulphate is commonly used. However, it is important to note that this medication should only be given once a decision to deliver has been made. In cases of eclampsia, an IV bolus of 4g over 5-10 minutes should be given, followed by an infusion of 1g/hour. During treatment, it is crucial to monitor urine output, reflexes, respiratory rate, and oxygen saturations. Respiratory depression can occur, and calcium gluconate is the first-line treatment for magnesium sulphate-induced respiratory depression. Treatment should continue for 24 hours after the last seizure or delivery, as around 40% of seizures occur post-partum. Additionally, fluid restriction is necessary to avoid the potentially serious consequences of fluid overload.

In summary, understanding the development of eclampsia and its treatment is crucial in managing this potentially life-threatening condition. Magnesium sulphate is the primary medication used to prevent and treat seizures, but it should only be given once a decision to deliver has been made. Monitoring vital signs and urine output is essential during treatment, and calcium gluconate should be readily available in case of respiratory depression. Finally, fluid restriction is necessary to avoid complications associated with fluid overload.

If a pregnant woman who is not immune to chickenpox is exposed to the virus, it is crucial to offer varicella-zoster immunoglobulin (VZIG) within 10 days of the exposure to reduce the risk of foetal varicella-zoster syndrome and potential complications for the mother. However, if the woman is under 20 weeks pregnant, oral acyclovir is not recommended as there is limited evidence for its efficacy in this situation. Giving both VZIG and oral acyclovir is impractical and inappropriate, especially since the woman has already been exposed to chickenpox. If the woman develops chickenpox before 20 weeks gestation, acyclovir may be considered, but VZIG should still be given to reduce the chance of severe infection. It is important to note that VZIG should be given before symptoms develop and is only effective up to 10 days post-exposure. Therefore, waiting for symptoms to appear before giving VZIG is not recommended.

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.

Prenatal Testing Options for Expecting Mothers

Expecting mothers have several options for prenatal testing to ensure the health of their developing baby. Chorionic villus sampling (CVS) is a diagnostic procedure that can be done from 11 weeks to detect chromosomal abnormalities. The risk of miscarriage is low, at 0.7% within 14 days and 1.3% within 30 days. Amniocentesis is another diagnostic option that can be done from 15 weeks, with a slightly lower risk of miscarriage at 0.6%.

Anomaly scans are typically done at 18-21 weeks to check for any physical abnormalities in the baby, such as spina bifida or anencephaly. The nuchal translucency test, combined with blood tests, is a screening test that can determine the individual’s risk for certain chromosomal abnormalities. The quadruple blood test is another screening option that measures various hormones and proteins to assess the risk of certain conditions.

Overall, expecting mothers have several options for prenatal testing to ensure the health of their baby. It is important to discuss these options with a healthcare provider to determine the best course of action for each individual pregnancy.

Understanding Prenatal Testing Options for Expecting Mothers

Injectable Contraceptives: Depo Provera

Injectable contraceptives are a popular form of birth control in the UK, with Depo Provera being the main option available. This contraceptive contains 150 mg of medroxyprogesterone acetate and is administered via intramuscular injection every 12 weeks. It can be given up to 14 weeks after the last dose without the need for extra precautions. The primary method of action is by inhibiting ovulation, while secondary effects include cervical mucous thickening and endometrial thinning.

However, there are some disadvantages to using Depo Provera. Once the injection is given, it cannot be reversed, and there may be a delayed return to fertility of up to 12 months. Adverse effects may include irregular bleeding and weight gain, and there is a potential increased risk of osteoporosis. It should only be used in adolescents if no other method of contraception is suitable.

It is important to note that there are contraindications to using Depo Provera, such as current breast cancer (UKMEC 4) or past breast cancer (UKMEC 3). While Noristerat is another injectable contraceptive licensed in the UK, it is rarely used in clinical practice and is given every 8 weeks. Overall, injectable contraceptives can be an effective form of birth control, but it is important to weigh the potential risks and benefits before deciding on this method.

Having had one previous caesarean section, the majority of women can have a successful vaginal delivery. A fundal placenta, which is attached at the top of the uterus away from the cervical os, is a favorable location for a placenta and does not require a caesarean section. However, a previous caesarean section does increase the risk of placenta praevia, where the placenta covers the cervical os, which may require a caesarean section. Inducing vaginal delivery at 36-37 weeks is not recommended in this case, as it is not a suitable option. While maternal age of 37 may pose some risks during pregnancy and birth, it is not a determining factor for a caesarean section unless there are other concerns.

Caesarean Section: Types, Indications, and Risks

Caesarean section, also known as C-section, is a surgical procedure that involves delivering a baby through an incision in the mother’s abdomen and uterus. In recent years, the rate of C-section has increased significantly due to an increased fear of litigation. There are two main types of C-section: lower segment C-section, which comprises 99% of cases, and classic C-section, which involves a longitudinal incision in the upper segment of the uterus.

C-section may be indicated for various reasons, including absolute cephalopelvic disproportion, placenta praevia grades 3/4, pre-eclampsia, post-maturity, IUGR, fetal distress in labor/prolapsed cord, failure of labor to progress, malpresentations, placental abruption, vaginal infection, and cervical cancer. The urgency of C-section may be categorized into four categories, with Category 1 being the most urgent and Category 4 being elective.

It is important for clinicians to inform women of the serious and frequent risks associated with C-section, including emergency hysterectomy, need for further surgery, admission to intensive care unit, thromboembolic disease, bladder injury, ureteric injury, and death. C-section may also increase the risk of uterine rupture, antepartum stillbirth, placenta praevia, and placenta accreta in subsequent pregnancies. Other complications may include persistent wound and abdominal discomfort, increased risk of repeat C-section, readmission to hospital, haemorrhage, infection, and fetal lacerations.

Vaginal birth after C-section (VBAC) may be an appropriate method of delivery for pregnant women with a single previous C-section delivery, except for those with previous uterine rupture or classical C-section scar. The success rate of VBAC is around 70-75%.

Understanding Post-Partum Haemorrhage: Types and Management

Post-partum haemorrhage (PPH) is a common complication of childbirth that can lead to serious maternal morbidity and mortality. There are two types of PPH: primary and secondary. Primary PPH occurs within 24 hours of delivery and is further classified as major or minor based on the amount of blood loss. Major PPH is defined as bleeding from the genital tract with an estimated blood loss of >1000mls, while minor PPH is defined as blood loss <1000mls within 24 hours of delivery. The most common cause of primary PPH is uterine atony. Secondary PPH, on the other hand, occurs from 24 hours until 12 weeks post-partum and is characterized by abnormal bleeding from the genital tract. Any bleeding from 24 hours until 36 hours post-partum with blood loss >500mls is considered secondary PPH.

Management of PPH centers around adequate resuscitation, bimanual uterine compression to stimulate contraction, and the use of IV oxytocin. While obstetric haemorrhage is no longer a major cause of maternal death in developed countries, it remains a significant problem in developing countries. Understanding the types and management of PPH is crucial in preventing maternal morbidity and mortality.

If a baby has a birth weight greater than 4kg, regardless of their gestational age, they are diagnosed with foetal macrosomia. This condition can cause dystocia, which may result in injuries to both the mother and baby. Dystocia may also require an operative vaginal delivery or Caesarean-section. Shoulder dystocia is the most common cause of damage to the upper brachial plexus, resulting in Erb’s palsy. This condition is characterized by the arm being adducted and internally rotated, with the forearm pronated, commonly referred to as the ‘waiter’s tip’. Damage to the lower brachial plexus can cause Klumpke’s palsy, which commonly affects the nerves that innervate the muscles of the hand.

Shoulder dystocia is a complication that can occur during vaginal delivery when the body of the fetus cannot be delivered after the head has already been delivered. This is usually due to the anterior shoulder of the fetus becoming stuck on the mother’s pubic bone. Shoulder dystocia can cause harm to both the mother and the fetus. Risk factors for shoulder dystocia include fetal macrosomia, high maternal body mass index, diabetes mellitus, and prolonged labor.

If shoulder dystocia is identified, it is important to call for senior help immediately. The McRoberts’ maneuver is often performed, which involves flexing and abducting the mother’s hips to increase the angle of the pelvis and facilitate delivery. An episiotomy may be performed to provide better access for internal maneuvers, but it will not relieve the bony obstruction. Symphysiotomy and the Zavanelli maneuver are not recommended as they can cause significant maternal morbidity. Oxytocin administration is not indicated for shoulder dystocia.

Complications of shoulder dystocia can include postpartum hemorrhage and perineal tears for the mother, and brachial plexus injury and neonatal death for the fetus. It is important to manage shoulder dystocia promptly and appropriately to minimize the risk of these complications.

Referral to gynaecology for urgent assessment and intravenous fluids is necessary if a pregnant woman experiences severe nausea and vomiting, weight loss, and positive ketones in her urine. This is especially important if the woman has a pre-existing condition that may be affected by prolonged nausea and vomiting, such as diabetes. Caution should be exercised when prescribing metoclopramide to young women due to the risk of extrapyramidal side effects. In this case, hospital management and assessment for intravenous fluids are necessary, and it would not be appropriate to simply reassure the patient and discharge her.

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.

If the Bishop score is less than or equal to 6, the recommended method for inducing labor is through vaginal PGE2 or oral misoprostol. In this case, since the Bishop score was less than 5, labor is unlikely without induction. One option could be to repeat a membrane sweep, but the most appropriate course of action would be to use a vaginal prostaglandin gel.

Induction of labour is a process where labour is artificially started and is required in about 20% of pregnancies. It is indicated in cases of prolonged pregnancy, prelabour premature rupture of the membranes, maternal medical problems, diabetic mother over 38 weeks, pre-eclampsia, obstetric cholestasis, and intrauterine fetal death. The Bishop score is used to assess whether induction of labour is necessary and includes cervical position, consistency, effacement, dilation, and fetal station. A score of less than 5 indicates that labour is unlikely to start without induction, while a score of 8 or more indicates a high chance of spontaneous labour or response to interventions made to induce labour.

Possible methods of induction include membrane sweep, vaginal prostaglandin E2, oral prostaglandin E1, maternal oxytocin infusion, amniotomy, and cervical ripening balloon. The NICE guidelines recommend vaginal prostaglandins or oral misoprostol if the Bishop score is less than or equal to 6, while amniotomy and an intravenous oxytocin infusion are recommended if the score is greater than 6.

The main complication of induction of labour is uterine hyperstimulation, which refers to prolonged and frequent uterine contractions that can interrupt blood flow to the intervillous space and result in fetal hypoxemia and acidemia. Uterine rupture is a rare but serious complication. Management includes removing vaginal prostaglandins and stopping the oxytocin infusion if one has been started, and considering tocolysis.

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.

Types of Miscarriage: Understanding the Differences

Miscarriage is a devastating experience for any woman. It is important to understand the different types of miscarriage to help manage the situation and provide appropriate care. Here are the different types of miscarriage and their characteristics:

Inevitable Miscarriage: This occurs when the products of conception are being passed vaginally, and the cervical os is open. It is an inevitable event.

Complete Miscarriage: This occurs when all the products of conception have been passed, and the cervical os is closed.

Threatened Miscarriage: This is characterised by vaginal bleeding and cramps, but the patient is not passing tissue vaginally. The uterus is of the right size for dates, and the cervical os is closed.

Septic Miscarriage: This occurs when there are retained products of conception in the uterus or cervical canal, leading to infection. The cervical os is likely to be open.

Missed Miscarriage: This is when the fetus dies in utero but is not expelled from the uterus. The uterus is small for dates, and the cervical os is closed.

Understanding the different types of miscarriage can help healthcare providers provide appropriate care and support to women experiencing this difficult event.

The quadruple test result shows a decrease in AFP, oestriol, and hCG, without change in inhibin A, indicating Edward’s syndrome. This condition is caused by trisomy 18 and can present with physical features such as micrognathia, low-set ears, rocker bottom feet, and overlapping fingers. The quadruple test is a screening test used to identify pregnancies with a higher risk of Down’s syndrome, Edwards’ syndrome, Patau’s syndrome, or neural tube defects. It is typically offered to patients who discover their pregnancy late and are no longer eligible for the combined test. ARPKD cannot be diagnosed with a quadruple test, but it can be detected prenatally with an ultrasound. Down’s syndrome would present with low AFP, low unconjugated oestriol, high hCG, and inhibin A, while neural tube defects would present with high AFP and normal oestriol, hCG, and inhibin A.

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.

The correct result for the quadruple test in a patient with Down’s syndrome is a decrease in AFP and oestriol, and an increase in hCG and inhibin A. This test is recommended by NICE for pregnant patients between 15-20 weeks gestation. If the screening test shows an increased risk, further diagnostic tests such as NIPT, amniocentesis, or chorionic villous sampling may be offered to confirm the diagnosis. It is important to note that a pattern of decreased AFP, decreased oestriol, decreased hCG, and normal inhibin A is suggestive of an increased risk of Edward’s syndrome. Increased AFP, increased oestriol, decreased hCG, and decreased inhibin A or any other combination of abnormal results may not be indicative of Down’s syndrome.

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.

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.

The patient’s symptoms suggest an infectious process, as evidenced by her fever, rapid heartbeat, and elevated levels of neutrophils (which are already higher than normal during pregnancy). Chorioamnionitis is a clinical diagnosis that may be indicated by uterine tenderness and a foul-smelling discharge, and the presence of a baseline fetal tachycardia supports this diagnosis. The likely cause of the infection is prolonged premature rupture of membranes. Although the patient has a history of uterine fibroids, this is not relevant to her current condition, as fibroids typically cause symptoms earlier in pregnancy. Acute placental abruption would cause sudden abdominal pain, which is not present in this case. While pyelonephritis is a possible differential diagnosis, the absence of dysuria makes it less likely.

Understanding Chorioamnionitis

Chorioamnionitis is a serious medical condition that can affect both the mother and the foetus during pregnancy. It is caused by a bacterial infection that affects the amniotic fluid, membranes, and placenta. This condition is considered a medical emergency and can be life-threatening if not treated promptly. It is more likely to occur when the membranes rupture prematurely, but it can also happen when the membranes are still intact.

Prompt delivery of the foetus is crucial in treating chorioamnionitis, and a cesarean section may be necessary. Intravenous antibiotics are also administered to help fight the infection. This condition affects up to 5% of all pregnancies, and it is important for pregnant women to be aware of the symptoms and seek medical attention immediately if they suspect they may have chorioamnionitis.

After a vaginal delivery, the loss of blood exceeding 500 ml is referred to as postpartum haemorrhage.

Understanding Postpartum Haemorrhage

Postpartum haemorrhage (PPH) is a condition where a woman experiences blood loss of more than 500 ml after giving birth vaginally. It can be classified as primary or secondary. Primary PPH occurs within 24 hours after delivery and is caused by the 4 Ts: tone, trauma, tissue, and thrombin. The most common cause is uterine atony. Risk factors for primary PPH include previous PPH, prolonged labour, pre-eclampsia, increased maternal age, emergency Caesarean section, and placenta praevia.

In managing PPH, it is important to involve senior staff immediately and follow the ABC approach. This includes two peripheral cannulae, lying the woman flat, blood tests, and commencing a warmed crystalloid infusion. Mechanical interventions such as rubbing up the fundus and catheterisation are also done. Medical interventions include IV oxytocin, ergometrine, carboprost, and misoprostol. Surgical options such as intrauterine balloon tamponade, B-Lynch suture, ligation of uterine arteries, and hysterectomy may be considered if medical options fail to control the bleeding.

Secondary PPH occurs between 24 hours to 6 weeks after delivery and is typically due to retained placental tissue or endometritis. It is important to understand the causes and risk factors of PPH to prevent and manage this life-threatening emergency effectively.

The progesterone-only pill can be taken by postpartum women (both breastfeeding and non-breastfeeding) at any time after delivery. It is categorized as UKMEC 1, meaning there are no restrictions on its use. Women can start taking it immediately if they choose to do so, and there is no need to wait for three weeks before starting. The combined oral contraceptive pill (COCP) can be taken as UKMEC 2 after three weeks in non-breastfeeding women, and after six weeks in breastfeeding women or as UKMEC 1 in non-breastfeeding women. In breastfeeding women, the COCP can be taken as UKMEC 1 after six months. The progesterone-only pill is safe for breastfeeding women as it has minimal transfer into breast milk, and there is no harm to the baby.

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.

In cases where the previous method is unsuccessful, an episiotomy may be necessary to facilitate internal maneuvers. Various alternatives may be considered, such as…

Shoulder dystocia is a complication that can occur during vaginal delivery when the body of the fetus cannot be delivered after the head has already been delivered. This is usually due to the anterior shoulder of the fetus becoming stuck on the mother’s pubic bone. Shoulder dystocia can cause harm to both the mother and the fetus. Risk factors for shoulder dystocia include fetal macrosomia, high maternal body mass index, diabetes mellitus, and prolonged labor.

If shoulder dystocia is identified, it is important to call for senior help immediately. The McRoberts’ maneuver is often performed, which involves flexing and abducting the mother’s hips to increase the angle of the pelvis and facilitate delivery. An episiotomy may be performed to provide better access for internal maneuvers, but it will not relieve the bony obstruction. Symphysiotomy and the Zavanelli maneuver are not recommended as they can cause significant maternal morbidity. Oxytocin administration is not indicated for shoulder dystocia.

Complications of shoulder dystocia can include postpartum hemorrhage and perineal tears for the mother, and brachial plexus injury and neonatal death for the fetus. It is important to manage shoulder dystocia promptly and appropriately to minimize the risk of these complications.

Medical and Surgical Management of Termination of Pregnancy

Medical and surgical management are two options for termination of pregnancy. Medical management involves the use of oral mifepristone followed by vaginal misoprostol. This method is recommended for termination of pregnancy before 13 weeks’ gestation and can be performed in an inpatient setting. The patient is administered the medication in hospital and will stay in the clinic or hospital to pass the pregnancy. Appropriate analgesia and antiemetics are given to take home, as required. The patient should be advised that there is a possibility medical management will fail and surgical management will need to take place.

Mifepristone is a competitive antagonist of progesterone for the progesterone receptor. It promotes degradation of the decidualised endometrium, cervical ripening and dilation, as well as increases the sensitivity of the myometrium to the effect of prostaglandins. Misoprostol, a synthetic prostaglandin E1, in turn, binds avidly to myometrial cells, promoting contraction of the uterus, and therefore expulsion of the products of conception. If this fails to empty the uterus, then a surgical procedure to manually evacuate the uterus is the next appropriate step in the patient’s management.

Surgical termination of pregnancy is first line for women presenting after 14 weeks’ gestation, women who have a preference over medical management and patients where medical termination has failed.

In cases where the patient has decided to proceed with termination of pregnancy, delaying the procedure is unethical and does not benefit the patient in any way. The patient should be fully informed of the risks associated with the procedure and given the necessary support.

Vaginal misoprostol can also be used in conjunction with mifepristone for medical termination of pregnancy or as monotherapy in medical management of miscarriage or induction of labour.

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.

Understanding Proteinuria in Pre-eclampsia: Screening and Management

Proteinuria, defined as urinary protein of >300 mg in 24 hours, is a key indicator of pre-eclampsia in pregnant women. Regular screening for hypertension and proteinuria should take place during antenatal clinics to detect this unpredictable condition. If blood pressure is found to be elevated, pharmacological management with medications such as labetalol, methyldopa, or nifedipine may be necessary. The severity of pre-eclampsia is determined by blood pressure readings, with mild cases requiring monitoring only and severe cases requiring frequent monitoring and medication. Pre-eclampsia is a serious condition that can lead to complications for both mother and baby, and ultimately, delivery of the baby is the only cure. Understanding proteinuria and its management is crucial in the care of pregnant women with pre-eclampsia.

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.

A second-degree perineal tear can be repaired on the ward by a midwife or clinician with sufficient experience. This type of tear involves the perineal muscle but not the anal sphincter, and is commonly seen in first-time mothers. Repairing the tear on the ward is a safe option that does not pose any long-term risks. For first-degree tears, a conservative approach is usually taken as they only involve superficial damage. Packing and healing by secondary intention is not appropriate for perineal tears, as it is a treatment for abscesses. Referring the patient to a urogynaecology clinic is also not necessary, as perineal tears require immediate repair. Repair in theatre is reserved for third and fourth-degree tears, which involve the anal sphincter complex and rectal mucosa.

Perineal tears are a common occurrence during childbirth, and the Royal College of Obstetricians and Gynaecologists (RCOG) has developed guidelines to classify them based on their severity. First-degree tears are superficial and do not require any repair, while second-degree tears involve the perineal muscle and require suturing by a midwife or clinician. Third-degree tears involve the anal sphincter complex and require repair in theatre by a trained clinician, with subcategories based on the extent of the tear. Fourth-degree tears involve the anal sphincter complex and rectal mucosa and also require repair in theatre by a trained clinician.

There are several risk factors for perineal tears, including being a first-time mother, having a large baby, experiencing a precipitant labour, and having a shoulder dystocia or forceps delivery. It is important for healthcare providers to be aware of these risk factors and to provide appropriate care and management during childbirth to minimize the risk of perineal tears. By following the RCOG guidelines and providing timely and effective treatment, healthcare providers can help ensure the best possible outcomes for both mother and baby.

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.

Women on antiepileptics trying to conceive should receive 5mg folic acid. Letrozole and clomiphene are not appropriate for this patient. Adequate control of epilepsy is important and medication changes should be made by a specialist. This patient should be started on a high dose of folic acid due to the risk of neural tube defects.

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.

If a baby loses more than 10% of its birth weight, it is necessary to refer the mother and baby to a midwife for assistance in increasing the baby’s weight.

Breastfeeding Problems and Their Management

Breastfeeding is a natural process, but it can come with its own set of challenges. Some of the minor problems that breastfeeding mothers may encounter include frequent feeding, nipple pain, blocked ducts, and nipple candidiasis. These issues can be managed by seeking advice on proper positioning, trying breast massage, and using appropriate medication.

Mastitis is a more serious problem that affects around 1 in 10 breastfeeding women. It is characterized by symptoms such as fever, nipple fissure, and persistent pain. Treatment involves the use of antibiotics, such as flucloxacillin, for 10-14 days. Breastfeeding or expressing milk should continue during treatment to prevent complications such as breast abscess.

Breast engorgement is another common problem that causes breast pain in breastfeeding women. It occurs in the first few days after birth and affects both breasts. Hand expression of milk can help relieve the discomfort of engorgement. Raynaud’s disease of the nipple is a less common problem that causes nipple pain and blanching. Treatment involves minimizing exposure to cold, using heat packs, and avoiding caffeine and smoking.

If a breastfed baby loses more than 10% of their birth weight in the first week of life, it may be a sign of poor weight gain. This should prompt consideration of the above breastfeeding problems and an expert review of feeding. Monitoring of weight should continue until weight gain is satisfactory.

Gestational diabetes is a condition where pregnant women experience high blood sugar levels. It is diagnosed through a 2-hour oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy. Women with risk factors such as a BMI over 30, a previous macrosomic baby, a family history of diabetes, or from an area with high diabetes prevalence should be offered the test. Random serum glucose, fasting serum glucose, HbA1c, and urinalysis are not recommended for diagnosis. Gestational diabetes can have negative effects on both the mother and fetus, including fetal macrosomia, stillbirth, neonatal hypoglycemia, and an increased risk of type II diabetes and obesity in the baby’s later life. Women with pre-existing diabetes should have their HbA1c monitored monthly and at booking to assess pregnancy risk, but HbA1c is not used to diagnose gestational diabetes. Early detection and management of gestational diabetes is crucial to prevent complications.

Breastfeeding mothers should avoid taking sulfonylureas (such as gliclazide) as there is a potential risk of causing hypoglycemia in newborns. Similarly, exenatide, liraglutide, and sitagliptin should also be avoided during breastfeeding. However, it is safe to use metformin while breastfeeding.

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.

This patient has intrahepatic cholestasis of pregnancy, which is characterized by abnormal liver function tests and severe itching in the third trimester. This condition increases the risk of stillbirth and maternal complications, particularly after 37 weeks of gestation. Therefore, induction of labor is typically recommended at this point, especially for patients with elevated transaminases and bile acids. While increased fetal monitoring is advised, hospitalization is not necessary unless there are signs of immediate concern for the fetus. A vaginal birth is usually appropriate, and a cesarean section is rarely required unless there are indications of non-reassuring fetal status. Although antihistamines can provide symptomatic relief, they are not sufficient on their own due to the risks associated with this condition. Other options for symptom relief include ursodeoxycholic acid, cholestyramine, and topical emollients. There is no indication for immediate delivery, as fetal movements and ultrasound results are normal.

Intrahepatic Cholestasis of Pregnancy: Symptoms and Management

Intrahepatic cholestasis of pregnancy, also known as obstetric cholestasis, is a condition that affects approximately 1% of pregnancies in the UK. It is characterized by intense itching, particularly on the palms, soles, and abdomen, and may also result in clinically detectable jaundice in around 20% of patients. Raised bilirubin levels are seen in over 90% of cases.

The management of intrahepatic cholestasis of pregnancy typically involves induction of labor at 37-38 weeks, although this practice may not be evidence-based. Ursodeoxycholic acid is also widely used, although the evidence base for its effectiveness is not clear. Additionally, vitamin K supplementation may be recommended.

It is important to note that the recurrence rate of intrahepatic cholestasis of pregnancy in subsequent pregnancies is high, ranging from 45-90%. Therefore, close monitoring and management are necessary for women who have experienced this condition in the past.
