Outline the anaesthetic management of obstetric complication preeclampsia?
The anaesthetic management of obstetric complication preeclampsia requires careful assessment, monitoring, and intervention to optimize maternal and fetal outcomes while mitigating the risks associated with this condition.

Preoperative Assessment:Obtain a detailed medical history, including the severity and duration of preeclampsia, maternal comorbidities, gestational age, and fetal status. Assess the degree of hypertension, proteinuria, and end-organ involvement (e.g., renal dysfunction, hepatic impairment, neurological symptoms) to determine the severity of preeclampsia and the need for urgent intervention. Review laboratory investigations, including complete blood count, liver function tests, renal function tests, coagulation profile, and assessment of platelet count and function. Evaluate maternal airway status, cardiovascular function, and fluid status to identify potential risks and plan appropriate perioperative management strategies. Choice of Anaesthesia:Neuraxial anaesthesia (spinal or epidural) is generally preferred for cesarean section in patients with preeclampsia, as it provides effective surgical anaesthesia while minimizing the risk of perioperative complications associated with general anaesthesia. General anaesthesia may be indicated in cases where neuraxial anaesthesia is contraindicated or unavailable, or in emergent situations requiring rapid delivery. Intraoperative Management: Neuraxial Anaesthesia:Preload the patient with intravenous fluids to optimize maternal preload and mitigate the risk of hypotension associated with neuraxial blockade. Consider prophylactic vasopressor administration (e.g., phenylephrine infusion) to prevent or treat maternal hypotension during neuraxial anaesthesia. Monitor maternal blood pressure, heart rate, oxygen saturation, and uterine perfusion continuously throughout the procedure. General Anaesthesia:Use rapid sequence induction (RSI) technique to minimize the risk of aspiration pneumonitis and ensure rapid maternal airway control. Administer induction agents and neuromuscular blocking agents cautiously, considering maternal hemodynamics and fetal well-being. Intubate the trachea with care to avoid hemodynamic instability and ensure adequate oxygenation and ventilation. Postoperative Care:Monitor the mother closely in the immediate postoperative period for signs of worsening preeclampsia, including hypertension, proteinuria, and signs of end-organ dysfunction. Provide appropriate pain management while considering the maternal-fetal effects of analgesic medications. Monitor the newborn for signs of neonatal depression, respiratory distress, and other complications requiring intervention or observation. Ensure appropriate follow-up care for both mother and baby, including monitoring of blood pressure, renal function, and coagulation status in the mother, and assessment of neonatal well-being. Multidisciplinary Collaboration:Collaborate closely with obstetricians, maternal-fetal medicine specialists, neonatologists, and other members of the healthcare team to coordinate care and optimize outcomes for both mother and baby. Communicate effectively regarding the maternal condition, anaesthetic plan, and perioperative management strategies to ensure a comprehensive and integrated approach to care. Emergent Situations:Be prepared to manage emergent complications associated with preeclampsia, such as eclampsia (seizures), HELLP syndrome (hemolysis, elevated liver enzymes, low platelets), or pulmonary edema, with prompt recognition and intervention to stabilize the mother and fetus.
The anaesthetic management of obstetric complication preeclampsia requires careful assessment, monitoring, and intervention to optimize maternal and fetal outcomes while mitigating the risks associated with this condition. Here's an outline of the anaesthetic management of preeclampsia:
By following these principles and strategies, healthcare providers can effectively manage the anaesthetic care of patients with preeclampsia, optimizing maternal and fetal outcomes while addressing the unique challenges associated with this obstetric complication.
