AbstractBackground: Dengue, a mosquito-borne viral infection, can lead to severe complications like dengue shock syndrome and severe thrombocytopenia. Pregnant patients with dengue present unique anaesthetic challenges. In this case series, we present the anaesthetic management of four pregnant patients with dengue who required emergency caesarean delivery.
Case Illustration : All patients had severe thrombocytopenia and required platelet transfusions. Two patients developed respiratory distress and pulmonary edema in the perioperative period. One patient had severe liver function abnormalities along with thrombocytopenia, complicating the diagnosis. All patients received intensive care unit (ICU) management. None of the neonates tested positive for dengue.
Discussion: The pathophysiological changes of pregnancy and dengue infection complicate the anaesthetic management of critically ill dengue patients. Thrombocytopenia and abnormal immune response lead to acute vascular permeability, plasma leakage, circulatory insufficiency, and polyserositis. Abnormal liver function tests and thrombocytopenia must be differentiated from HELLP syndrome. Over-transfusion of fluids due to shock can lead to pulmonary edema.
Conclusion: Pregnant patients with dengue fever pose a high risk of maternal and foetal mortality and morbidity. Successful anaesthetic management requires judicious transfusion of blood products and fluids based on the disease's complications and stage of illness. General anaesthesia is safe in these patients.
