Hemodynamic parameters were measured and recorded during recovery and operation, as well as the serum levels of magnesium, potassium, and creatine phosphokinase (CPK) before receiving magnesium sulfate, and 20 minutes after induction of anesthesia. Moreover, myoglobinuria was measured and recorded.Findings: Specific reductions were found in moderate blood pressure and heart rate at third minute after laryngoscopy in groups receiving magnesium sulfate (P < 0.001 for both). Fasciculation was observed in 53.6% of the patients receiving magnesium sulfate, and 87.2% of the patients in the placebo group. The fasciculation observed in groups receiving magnesium sulfate was classified as mild.Conclusion: Administration of magnesium sulfate 30 mg/kg as well as 40 mg/kg before cesarean section under general anesthesia can effectively reduce the severity of fasciculation and myalgia, and the effects of succinylcholine on rapid induction of anesthesia in pregnant women.
