Background: This study aimed to determine the effect of intravenous infusion of magnesium sulfate in three doses before the end of the surgery for prevention of shivering after abdominal surgeries under general anesthesia.Methods: In a clinical-trial study, 100 patients under abdominal surgeries were randomly divided in four groups. Before the reverse of anesthesia, one of the solutions included normal saline, and 30, 40 or 50 mg/kg magnesium sulfate were injected during 10 minutes for each group. The incidence of postoperative shivering mas measured and compared between the four groups.Findings: The incidence of shivering at the entrance to recovery room was 9, 3, 8 and 3 patients in normal saline, and 50, 40 and 30 mg/kg magnesium sulfate groups, respectively (P = 0.07). 15 minutes later, the incidence of shivering was 8, 1, 1 and 6 patients in mentioned groups, respectively (P = 0.01). 30 minutes after the entrance, the incidence of shivering was 4, 0, 1 and 4 patients in mentioned groups, respectively (P = 0.10).Conclusion: Using 40 or 50 mg/kg of magnesium sulfate is benefit for decreasing postoperative shivering and using these doses is recommended for prevention of postoperative shivering in patients under abdominal surgeries.
