Summary

Succinylcholine is currently the only depolarizing neuromuscular blocker widely used in anesthesia induction and is the drug of choice for rapid sequential anesthesia induction. However, with succinylcholine, varying degrees of muscle fibrillation and muscle pain occur. Intravenous injection of succinylcholine caused by myomuscular fibrillation can cause increased intragastric pressure, intraocular pressure and intracranial pressure, increased serum potassium and postoperative myalgia, increased the incidence of adverse events such as needle prolapse, extravasation of injected drugs, and reduced perioperative comfort of patients. Pretreatment with cisatracurium provides limited prevention of muscular fibrillation due to succinylcholine, but the choice of dose often depends on user experience, and there have been no previous studies of age-related doses of cisatracurium for the prevention of muscular fibrillation caused by succinylcholine, and its half-effective amount (ED50) has not been established. In this study, patients treated with elective general anesthesia surgery were the subjects, and in the process of general anesthesia induction, cis-atracurium was pretreated to evaluate the degree of inhibition of muscular fibrillation caused by succinylcholine, and half of the effective dose of cis-atracurium inhibition of muscular fibrillation caused by succinylcholine was calculated by sequential method.
