ABSTRACT

Introduction: Opioid analgesics have an advantage over nonsteroidal anti-inflammatory drugs in that they do not cause direct organ damage. Buprenorphine has an antinociceptive potency approximately 25-50 times greater than that of morphine. Hence, in this study, buprenorphine was added to local anaesthesia in relieving postoperative pain after lower third molar surgery when given as inferior alveolar nerve block. The aim of this study was to evaluate the efficacy of buprenorphine in managing postoperative pain after lower third molar surgery. Materials and Methods: Fifty patients requiring lower third molar surgery were randomly divided into two groups. Group A received buprenorphine added to 2% lignocaine with 1:80,000 adrenaline and Group B received 2% lignocaine with 1:80,000 adrenaline. Parameters assessed were onset of anaesthesia, depth of anaesthesia, intraoperative monitoring of adverse effects, duration of analgesia, and number of analgesics consumed. Statistical analysis was carried out using SPSS software version 21. The data were compared using Student's t-test. The level of significance was set at 0.05. Results: There was a significant difference in onset of anaesthesia between Group A and Group B (P < 0.05). Depth of anaesthesia and duration of analgesia were greater in Group A (56 h 36 min) than Group B (3 h 24 min). Analgesics consumed by Group A (0.9) were significantly less compared to Group B (9.2) and it was highly significant (P = 0.000). Discussion: Buprenorphine when added to local anaesthesia can prolong postoperative analgesia with minimum or no side effects. Hence, buprenorphine can be safely used for lower third molar surgery.
