Severe bradycardia and transient asystole during epidural anesthesia: A case report / 대한마취과학회지

ABSTRACT

The severe bradycardia and asystole are uncommon complications of epidural anesthesia but can be life threatening if not managed properly. A 73-year-old, ASA class 3, male patient was admitted for a total knee replacement under epidural anesthesia. Approximately 10 minutes after epidural anesthesia, the heart rate decreased significantly to 20 beats/min with asystole. The heart rate returned to 80 beats/min after administering atropine, ephedrine, and external cardiac compression. Severe bradycardia and asystole may be induced by vagal activation as a result of the low venous return and sympathetic blockade.
