We have studied in 60 patients undergoing minor muscle cutting surgeries under general anesthesia, the effectiveness and sequelae of pretreatment with rocuronium for reducing muscular side effects after succinylcholine as well as the muscular effects of rocuronium alone for intubation. Patients were randomly allocated to one of the two groups; group A received rocuronium for intubation and group B received succinylcholine for intubation 5 minutes after pretreatment with rocuronium. The group receiving rocuronium had significantly less muscular effects. At the same time the group receiving succinylcholine with rocuronium pretreatment, experienced a significant reduction in muscular side effects.
