ABSTRACT
BACKGROUND: The anesthetic management of pregnant women with acute heart failure remains challenging with regard to maintaining the hemodynamic status of the mother and baby. The likelihood of decreased blood pressure is lower with remimazolam than with propofol. However, there is no report of general anesthesia with remimazolam for cesarean section. CASE PRESENTATION: The patient was a 34-year-old pregnant woman who was diagnosed with acute heart failure associated with infective endocarditis. We performed cesarean section under general anesthesia using remimazolam, with percutaneous cardiopulmonary support on standby. The mother's mean blood pressure was maintained above 65 mmHg during the surgery, without catecholamines or vasopressors. The infant's Apgar scores were 4 at 1 min and 7 at 5 min. CONCLUSION: Cesarean section was successfully performed under general anesthesia with remimazolam in a pregnant patient with acute heart failure. Further studies are needed to clarify the association between remimazolam and neonatal hypotension.
