Prolonged paralysis associated with succinylcholine--a case report.

Prolonged paralysis is a rare complication of succinylcholine. We report a case of palmar hyperhidrosis who underwent transthoracic endoscopic sympathetic ganglionectomy under general anesthesia with a facemask developed prolonged paralysis following the operation. The prolonged paralysis supposedly caused by intraoperative use of succinylcholine was recognized and confirmed by laboratory examination which showed low pseudocholinesterase activity. In this report, we describe the course of the event and discuss the causes of delayed awakening associated with anesthesia and its management.
