Background and Aims: Shivering is a common problem during neuraxial anaesthesia. Neuraxial anaesthesia impairs thermoregulatory control and can occur in as many as 40%–70% of patients after regional anesthesia. This shivering, apart from its physiological and hemodynamic effects, has been described as even worse than surgical pain. The aim of the study was to evaluate the effectiveness of prophylactic use of intravenous ketamine, clonidine and tramadol in control of shivering and to note any side-effects of the drugs used. Material and Methods: A total number of 90 ASA I and II patients of either sex belonging to age group 18-60 years posted for Lower Abdomen and Lower Limb surgeries were divided into three groups of 30 each. Group P (control group): Patients received 10mL of normal saline IV as placebo. Group K: Patients received Inj. Ketamine 0.5mg/kgBW IV diluted to 10ml in Normal Saline. Group T: patients received Inj. Tramadol 0.5mg/kgBW IV diluted to 10ml in normal saline. Results: Shivering after spinal anesthesia was comparatively better controlled in group receiving Ketamine 0.5mg/kg and tramadol 0.5mg/kg as compared to control group (P<0.05). Conclusion: We conclude that giving Ketamine 0.5mg/kg, tramadol 0.5mg/kg i.v. prophylactically just before subarachnoid block significantly decreased the incidence of shivering without causing any major side effects. Using ketamine may be more beneficial as it improves the hemodynamic profile by its sympathomimetic effects and it sedates the patient effectively, which increases patient comfort during surgery, maintains cardio-respiratory stability and prevents recall of unpleasant events during the surgery.
