Abstract

Introduction: The pain is one of the most common complications of tonsillectomy that causing to take longer the recovering and hospitalization period. There are some common drugs and medications such as bupivacaine used to treat postoperative pain. This research aims to study the effect of bupivacaine injection on reducing the posttonsillectomy pain. Methodology: This is a double-blind clinical trial consisted of 96 patients aged 5 to 12 selected to undergo tonsillectomy. At the beginning of the operation, patients in group A received an injection of 3cc of 0.5% bupivacaine and patients in group B were injected 3cc of normal saline in side and upper peritonsillar areas. After tracheal intubation,1, 2, 4, 8, 12, and 24 hours after the operation, pain was measured by VAS. The first request for analgesic and the total amount of analgesic consumption was also recorded. Results: Using VAS, it was found out that the amount of pain in the group receiving bupivacaine (group A) was significantly less than the group receiving normal saline and the bupivacaine group suffered less pain (p<0.05). It took longer time for the group receiving bupivacaine to request for analgesic. In general, demand for analgesic in 24 hours after surgery was significantly less in group A than in the group received normal saline (p<0.001). Conclusion: It can be concluded that 0.5% bupivacaine locally relieves the posttonsillectomy pain and significantly reduces the need to postoperative analgesic.
