Abstract
INTRODUCTION: Post-operative pain after orthopedic surgery has remained a challenging problem, which prolongs hospital stay and early rehabilitation. Pregabalin comes under the class of gabapentinoids that have been used in postoperative pain in arthroplasty and spine surgeries but studies regarding its role as pre-emptive analgesia in orthopedic limb surgeries are very few. AIMS: To compare the efficacy of pre-operative pregabalin with a placebo drug in early post-operative pain management for lower limb orthopedics surgeries. MATERIALS AND METHODS: A randomized double blinded prospective study was undertaken. Sixty patients were enrolled with age between 18 and 70 years and were divided into 2 groups. Group A - received 150 mg of oral pregabalin capsule, and Group B - received matched color empty capsules. Standard spinal anesthesia was given. Breakthrough analgesia was given with an injection of tramadol 50 mg intravenous. Assessment of pain was done with a Visual Analog Scale (VAS) at 6, 12, 24, and 48 h. RESULTS: In comparison to Group B, Group A had a significantly lower postoperative VAS score and required much less breakthrough analgesia within the 1st 24 h after surgery. CONCLUSION: In orthopedic lower limb fracture surgeries, pre-emptive pregabalin of 150 mg provides adequate postoperative analgesia with relatively few unfavorable side effects.
