IntroductionPostanaesthetic shivering is a common condition after surgery which needs proper management with pharmacologic agents so as to make postoperative period comfortable to the patient and prevent from the untoward complications that can arise from it. This study was done to compare the effectiveness of Pethidine and Doxapram in the treatment of postanaesthetic shivering.MethodsPatients were randomly divided into three groups, ten in each. All received volume of 3 ml as Group I (Doxapram 1.5 mg/kg), Group II (Pethidine 0.35 mg/kg) and Group III (Normal Saline). All patients were observed for 30 minutes after reversal of muscle relaxant and occurrence of shivering within this period was observed, scored and treated. All treated patients were observed for 10 minutes after the test drug was given for control of shivering and any untoward effects.ResultsPethidine was found more effective than Doxapram in treating postanaesthetic shivering as it was effective in 80% followed by Doxapram in 60% and Normal saline in 20%. Statistically the results between Normal saline and Pethidine was significant as P < 0.05. As statistical significance between Doxapram and Normal Saline was p = 0.16; and between Pethidine and Doxapram was p = 0.62, the difference is statistically not significant.ConclusionsPethidine was found to be more effective compared to Doxapram in treating patients with postoperative shivering.
