RESUMEN
The purpose of this study was to assess the percentage of patients experiencing post-succinylcholine pain and outcome of the management. It was a comparative study conducted in the Department of Anesthesiology of post Graduate Lady Reading Hospital, Peshawar from September 1996 to February 1997. Eighty ASA I and II adults undergoing tonsillectomy were studied for the effects of pre-operative administration of pancuronium bromide on succinylcholine induced myalgia. Patients were randomly divided into two groups, one group received succinylcholine as a muscle relaxant, while the other group received pancuronium bromide as a pretreatment agent 3 minute before succinyl. Muscle fasciculations, intubation conditions and post-operative myalgia were graded numerically. Post-operative myalgia in the group treated with pancuronium bromide was significantly less [<0.05] than in the control group
