Abstract
INTRODUCTION: Conquering postoperative pain which has significant impact on the surgery outcome can be challenging for the clinicians. Pregabalin is a GABA analogue used for various neuropathic pain syndromes. Very few studies are there with the use of pregabalin as a preemptive analgesic for orthopedic surgeries. AIM: To compare pregabalin 150 mg with placebo for postoperative pain control in patients undergoing elective lower limb orthopedic surgeries under spinal anaesthesia and to assess any side effects. MATERIALS AND METHODS: A randomized double blinded prospective study was undertaken. Ninety patients with ASA physical statusI, II, aged between 18-50 years were enrolled in the study. One hour prior to spinal anaesthesia Group C - received colour matched empty capsules, Group P - received 150mg of oral pregabalin. Spinal anaesthesia was administered in sitting position in L3-L4 space with Inj. Bupivacaine heavy (0.5%) at a dose of 0.3mg/kg body weight with 20 mg being the maximum dose using 25 gauge spinal needle. Rescue analgesia was provided with using Inj. Diclofenac 1.5 mg/kg intramuscular. RESULTS:Time for rescue analgesia (VAS score >3) was significantly increased in Group P than in Group C. The total dose of diclofenac required in the 24 hour postoperative period was significantly lower in Group P than in Group C. The sedation scores and patient satisfaction scores were also more in Group P than in Group C. CONCLUSION:Preemptive pregabalin in an oral dose of 150 mg offers good postoperative analgesia in lower limb orthopedic surgeries under spinal anaesthesia.
