Evaluation of Efficacy of Tramadol and Pethidine for Control of Perioperative Shivering in Patients Undergoing Elective Surgery under Spinal Anaesthesia

Evaluation of efficacy of tramadol and pethidine for control of perioperative shivering in patients undergoing elective surgery under spinal anaesthesia. Perioperative shivering had decremental effects which leads to change in vitals and increase in oxygen consumption, catecholamine secretion, co2 production. In this study we have used drugs Tramadol and pethidine (0.5mg/kg) for control of peri operative shivering, our main aim was to evaluate the efficacy of tramadol and pethidine for control of perioperative shivering in patients undergoing elective surgery under spinal anaesthesia. Written and informed consent obtained and ASA I and II undergoing surgery under spinal anaesthesia were selected. During perioperative if patients develop shivering either inj. tramadol 0.5mg/kg (group T) or inj. Pethidine 0.5mg/kg (group P) was administered. Both the drugs were evaluated for the efficacy to control shivering and side effects. In group T, 13 patients of 15 showed control of shivering while in group P 11 patients showed control of shivering (p less than 0.05). Incidence of nausea is more in tramadol group than pethidine group (8 patients to 5 patients). Tramadol is more effective than pethidine for controlling of perioperative shivering.
