title: Volume manipulation by phlebotomy for cesarean section in a patient with pulmonary hypertension.
abstract: Pulmonary hypertension in a parturient is known for its high perioperative mortality. We describe a successful case of cesarean section performed under general anesthesia in a parturient with pulmonary hypertension. A distinctive feature of our management was active blood volume manipulation by phlebotomy and reinfusion of the blood. Just after the baby was delivered, about 250 ml of blood was phlebotomized to counteract autotransfusion by the contracting uterus. We stopped phlebotomy at this volume because moderate systemic hypotension occurred. The blood was slowly infused, with transesophageal echocardiography used to evaluate right ventricle filling. The patient was hemodynamically stable during the operation and had an uneventful postpartum period. Her baby's perioperative course was also uneventful.
