Adrenaline is an integral part of Advanced Life Support attempts during cardiac arrest, with a recommended dose of 1 mg given immediately and then after every 2 cycles. However, there is increasing evidence that the use of adrenaline during resuscitation attempts may be detrimental to a patient’s chance of survival. Atropine, a drug used in bradycardia, was removed from the algorithm for Advanced Life Support in 2010 as there was little evidence it had any effect in cardiac arrest situations.

Diagnosis of Subarachnoid Hemorrhage

When a patient is suspected of having subarachnoid hemorrhage (SAH), the initial diagnostic test should be a computerised tomography (CT) head scan. This test can identify over 93% of SAH cases within 24 hours. However, if the CT scan is normal or inconclusive and there is still a high clinical suspicion of SAH, a lumbar puncture should be performed.

During the lumbar puncture, cerebrospinal fluid (CSF) is collected in four tubes and the red blood cell (RBC) count is determined in tubes one and four. If the RBC count does not decrease between these tubes and there is an elevated opening pressure, along with the development of xanthochromia (which may take up to 12 hours from the onset of headache), SAH is suggested. It is important to note that a Glasgow coma scale score of 15 does not rule out SAH.

While magnetic resonance imaging (MRI) may be a useful diagnostic tool, it takes too long to arrange and CT head scans are an excellent first line investigation for SAH. Early diagnosis and treatment of SAH is crucial for improving patient outcomes.

Initial and Long-Term Treatment for Inferolateral ST-Elevation MI

The patient’s history and ECG findings suggest that they are experiencing an Inferolateral ST-elevation MI. The best initial treatment for this condition would be percutaneous coronary intervention. It is likely that the patient would have already received aspirin in the ambulance.

For long-term treatment, the patient will require dual antiplatelet therapy, such as aspirin and clopidogrel, a statin, a beta blocker, and an ACE-inhibitor. These medications will help manage the patient’s condition and prevent future cardiac events.

It is important to follow the NICE guideline for Acute Coronary Syndrome to ensure that the patient receives the appropriate treatment and care. By following these guidelines, healthcare professionals can help improve the patient’s prognosis and quality of life.

Management of Excessive Hyperglycaemia in a Dehydrated Patient

This patient is experiencing excessive hyperglycaemia, which is contributing to her symptoms and is related to hyperosmolarity. However, her normal bicarbonate levels suggest that she does not have Hyperosmolar Hyperglycaemic State (HHS), but rather dehydration. Additionally, her marked hyperglycaemia is likely caused by the dexamethasone she is taking, which is causing insulin resistance.

To manage her condition, the patient requires IV normal saline to address her dehydration, along with insulin to regulate her blood glucose levels. Once her blood glucose levels have decreased to 10 mmol/L, she can switch to IV dextrose. This approach will help to address her crystalloid requirements and manage her hyperglycaemia effectively.

In summary, managing excessive hyperglycaemia in a dehydrated patient requires a careful approach that addresses both the underlying cause of the hyperglycaemia and the patient’s hydration status. By providing IV fluids and insulin as needed, healthcare providers can help to regulate the patient’s blood glucose levels and improve their overall condition.

Subluxation of the Radial Head in Children

Subluxation of the radial head, also known as pulled elbow, is a frequent injury in young children. It occurs when the arm is pulled directly, causing the radial head to dislocate from its ligament. The child may experience pain in the elbow and have limited movement in supination and extension. They may also refuse to use their arm.

Fortunately, a diagnosis can often be made without the need for an x-ray if the history is typical. Treatment involves providing pain relief and manipulating the elbow by supination while it is flexed at a 90° angle. With proper care, most children recover quickly from this injury.

Importance of CT Head Scanning and Lumbar Puncture in Suspected Bacterial Meningitis

The availability of 24-hour computerised tomography (CT) head scanning in hospitals is crucial in the early recognition of any contraindications to lumbar puncture (LP) in patients with suspected bacterial meningitis. Prior to LP, a CT head scan should be performed to prevent the risk of brain herniation or coning. However, it is important to note that antibiotics should not be delayed while waiting for CT head scanning as this may prove fatal. In any case of suspected bacterial meningitis, a lumbar puncture must be performed to confirm the diagnosis and initiate appropriate treatment. Clinicians can refer to the Meningitis Research Foundation Clinician’s Guide to Recognition and Early Management of Meningococcal Disease in Children for further information.

Consider Pulmonary Embolism in Post-Surgery Patients

A patient who has recently undergone surgery and presents with chest x-ray changes and respiratory symptoms should be evaluated for pulmonary embolism (PE). While infection is a possibility, it is important to consider thromboembolic disease as it can be fatal if left untreated.

A ventilation/perfusion (V/Q) scan may not be sufficient in this context, and a computed tomography pulmonary angiogram (CTPA) would provide a more definitive diagnosis. While raised FDPs/D-dimers can indicate PE, they are not specific and only provide value if they fall within a normal range. Blood cultures for chest infection are unlikely to yield significant results.

It is crucial to consider the possibility of PE in post-surgery patients to ensure prompt and appropriate treatment.

Fluid Management in Burn Patients: Considerations for Initial Resuscitation and Maintenance

Burn patients require careful fluid management to replace lost fluid volume and electrolytes. In the initial resuscitation phase, it is important to administer fluids rapidly, with warm intravenous fluids considered to minimize heat loss. Accurate fluid monitoring and titration to urine output is vital. While colloids such as Gelofusin may be used, crystalloids like Hartmann’s or normal saline are preferred. Maintenance fluids should be based on the modified Parkland formula, with electrolyte losses in mind. However, in the initial phase, replacing lost fluid volume takes priority over maintenance fluids based on oral intake.

The Glasgow coma scale is a scoring system used to assess the level of consciousness of a patient. It ranges from 3 to 15, with 3 being the worst and 15 being the best. The scale is made up of three parameters: best eye response, best verbal response, and best motor response.

The best eye response is determined by how the patient reacts to visual stimuli, such as opening their eyes spontaneously or in response to a command. The best verbal response is graded on a scale of 1 to 5, with 1 being no response and 5 being an oriented patient who can answer questions appropriately. Finally, the best motor response is assessed by observing the patient’s movements, such as their ability to follow commands or move in response to pain.

Overall, the Glasgow coma scale is an important tool for healthcare professionals to assess the level of consciousness of a patient and determine the severity of their condition. By the different parameters and scores, medical professionals can provide appropriate treatment and care for their patients.

Diagnosis of Spontaneous Hypoglycaemia

The patient’s medical history and biochemical evidence suggest a diagnosis of spontaneous hypoglycaemia, with the most likely cause being an insulinoma. However, it is important to rule out the possibility of drug administration, and a sulphonylurea screen should be conducted. The patient has presented with symptomatic hypoglycaemia, despite not being diabetic and not having received insulin or a sulphonylurea. There is no indication of alcohol or drug misuse, nor is there any evidence of sepsis.

To confirm a diagnosis of spontaneous hypoglycaemia, a prolonged fast is necessary. If the patient experiences hypoglycaemia during the fast, insulin and C peptide levels should be measured to confirm the diagnosis. The patient’s cortisol response during the hypoglycaemic episode (cortisol 800) rules out hypoadrenalism.
