ABSTRACT
MATERIALS AND METHODS 90 Patients randomly allocated into three groups- qroup P, qroup G, qroup S in each group 30patientswere Selected Group P Patients were given Inj Pethidine 25 mg intravenously 5 minutes before induction of general anaesthesia. Group G Patients were given Inj Granisetron 40 microgram /Kgintravenously 5 minutes before induction of general anaesthesia. Group S Patients were given Saline intravenously 5 minutes before induction of general anaesthesia. RESULTS Postoperative shivering graded after extubation at 15 and 30 minutes interval no shivering in Pethidine group 83.3% {n= 25} Granisetron, qroup 73% {n=22} Placebo qroup 27% {n=8} P value not significant between P & G group but significant in Placebo qroup {P <0.05}. shivering occurs at grade 3in pethidine group 7% [n=2] Granisetron group 10%[n=3], Placebo group 60%[n=18] P value statistically not significant between P & G groups but significant in Placebo qroup {P <0.05}. CONCLUSION From this study prophylactic use of both Pethidine and Granisetron were equally effective for the prevention of postoperative shivering
