Abstract

Background: Regional techniques are commonly used for patients undergoing caesarean and these women experience shivering frequently. Present study was aimed to compare efficacy and safety of intravenous tramadol versus intravenous clonidine in controlling shivering in obstetric patients under regional anaesthesia for caesarean section. Material and Methods: Present study was prospective, comparative study, conducted in pregnant women, 18-40 years age, ASA grade I & II, developing shivering intra operative or postoperative in emergency or elective section. Results: Among 80 cases undergoing elective caesarean section, patients were divided into two groups of 40 each as group C - Received Clonidine 0.5mcg per kg i.v & group T- Received Tramadol 0.5mg per kg i.v. There was no significant difference in pre operative temperature, HR, SBP, DBP and SpO2 in both groups and even after the control of shivering. Mean time required to control the shivering in Tramadol group is 2.77 minutes is significantly less as compared to the Clonidine group which is 5.47 minutes (p< 0.001). Response rate that is the percentage of patients in which shivering controlled in 15 minutes after the treatment is 95% in Tramadol group and 82.5% in Clonidine group. The difference was not significant statistically (P-value 0.155). No side effects were noted in tramadol group, while 3 patients had side effects in clonidine group (1 nausea/vomiting & 2 cases had sedation), difference was not significant statistically. Conclusion: Tramadol as compared to Clonidine is safe and effective in controlling the shivering in obstetric patients receiving spinal anaesthesia.
