Introduction: Shivering is a frequent complication after regional anaesthesia and the primary cause of shivering is perioperative hypothermia. Nalbuphine and tramadol are opioids which have been used to control postanaesthetic shivering.
Aim: To compare the efficacy of nalbuphine and tramadol in the treatment of postspinal anaesthesia shivering.
Materials and Methods: This was a randomised clinical trial conducted on 60 patients of either gender (20-60 years age group) from January 2019 to June 2020, American Society of Anaesthesiologists (ASA) Grade I or II, having postspinal anaesthesia shivering. The total sample was divided into two groups of 30 patients each. Group T received injection inj. tramadol 1 mg/kg intravenously (IV) and Group N received Inj. nalbuphine 0.1 mg/kg IV. Grade of shivering was assessed with a five point scale. The time taken for disappearance of shivering, assessment of improvement of shivering (complete- if grade of shivering becomes 0, partial- if grade of shivering deceased but not zero), recurrence rate and side-effects such as nausea, vomiting, deep sedation were noted. Independent t-test and Chi-square test were used to analyse the data. A p-value <0.05 were considered statistically significant.
Results: The time taken for disappearance of shivering was shorter in group N than T (3.20±0.96 minutes and 6.43±0.97 minutes respectively, p=0.001). Significantly better sedation (p-value 0.04) was seen in nalbuphine group as grade 3 sedation were seen in 15 patients of nalbuphine group as compared to none in tramadol group. All the patients in group N had complete improvement of shivering and there was no recurrence, while in group T six patients had partial improvement in shivering and four (13%) had recurrence. Complications such as nausea (three patients) and vomiting (one patient) were seen in Group T while none were seen in Group N.
Conclusion: The efficacy of nalbuphine is greater than tramadol in controlling postspinal anaesthesia shivering, with minimal side-effects.
