We report successful anesthetic management of elective cesarean section in a 30-year-old patient with Basedow disease using landiolol hydrochloride, a short-acting beta-1 adrenergic blocker of which greatest advantages are its short duration of action, rapid clearance and high beta-1 selectivity. The patient received landiolol for the prevention of aggravated tachycardia and tachyarrhythmia during cesarean section. She received landiolol continuous infusion at a rate of 5 microg x kg x min(-1) to 8 microg x kg x min(-1) until the uneventful delivery of the infant with good Apgar score, under combined spinal epidural anesthesia (CESA). We could maintain maternal hemodynamics stable leading to good post-cesarean uterus contraction. No severe adverse effects were observed in the infant. In conculusion, landiolol is useful for maintaining the hemodynamics stable in a pregnant woman with Basedow disease and keeping the infant safe from any adverse effect by infusion of landiolol.
