Abstract
- The anticholinesterase pyridostigmine is usually used as a reversal agent of non-depolarizing muscle relaxants in general anesthesia. Most adverse muscarinic effects of anticholinesterases are controlled by anticholinergics; however, there is still a potential for fatal cardiac complications. We report a case of cardiac arrest associated with coronary vasospasm that developed during emergence from general anesthesia in a 61-year-old male patient undergoing uvulopalatopharyngoplasty with preoperatively undiagnosed coronary vasospastic angina. Anticholinesterases should be administered with caution for neuromuscular blockade reversal, especially in patients with coronary vasospastic angina.
