Spinal anesthesia can be utilized for emergency cesarean sections in parturients with complete heart block and pregnancy-induced hypertension to maintain hemodynamic stability.
The incidence of complete atrioventricular block first time during pregnancy is rare. Majority of cases remain asymptomatic and do not require any active intervention. Symptomatic ones can present with syncope, dyspnea, arrhythmia, heart failure or sudden cardiac death. The risk of syncope and sudden cardiac death is increased in patients with heart rate less than 50/ minute. The goal in the perioperative anesthetic management of this case is to preserve the heart rate and maintain hemodynamic stability. We present a case of 26 years old parturient with pregnancy-induced hypertension (PIH), complete heart block (CHB), intrauterine growth retardation (IUGR), and Rh incompatibility managed under spinal anesthesia.
