Regional anaesthesia (spinal anaesthesia) is widely used as a safe anaesthetic technique for both elective and emergency operations. Shivering causes several undesirable physiologic consequences including increase in oxygen consumption, hypercarbia and increase in minute ventilation. Present study was aimed to compare intravenous tramadol versus intravenous dexmedetomidine in the prevention of intraoperative shivering in patients undergoing surgery under subarachnoid blockade. Present study was prospective, randomised, comparative study, conducted in patients of age 20-65 years, either gender, corresponding to ASA status I/II undergoing elective surgery under spinal anaesthesia <150 min duration with surgeries involving lower abdomen, urological, gynaecological, orthopaedic and lower limb extremity. In present study 60 patients were randomly allocated into group T (n = 30, received tramadol) and group D (n = 30, received dexmedetomidine). Patients having severity score of shivering of 3 and 4 were treated with Pethidine. In group T, incidence of shivering was 23.33% as compared to group D with incidence of 13.33%, difference between two groups was statistically significant (p = 0.045). Onset of shivering after spinal anaesthesia was at 21.4±8.5 min in group T as compared to 26.3±10.3 min in group D, difference statistically significant (p = 0.049). We noted delayed cessation of shivering after medication in group T (4.91±0.93 min) than in group D (3.12±0.71 min), difference was statistically significant (p = 0.01). In group D sedation (23.33%) and hypotension (3.33%) was noted as adverse effects while in group T sedation (10%), hypotension (10%), nausea (6.67%) and vomiting (6.67%) were noted. Intravenous dexmedetomidine had less incidence of intra-operative shivering, late onset of intra-operative shivering and lesser side effects when compared to tramadol for intra-operative shivering in patients undergoing surgery under subarachnoid blockade.
