Comparing the Level of Effect of Pre-Incisional Topical Injections of Two Drugs of Bupivacaine and Ketamine in Pain Reduction After Tonsillectomy

Pain after surgery is one of the more suffering aspects of Tonsillectomy surgery. Although various types of painkillers have been used to alleviate the pain after the surgery, this issue is yet to be solved efficiently. Hence, this study has been undertaken with the purpose of comparing the level of effect of pre-incisional topical injections of two drugs of bupivacaine and ketamine in pain reduction after Tonsillectomy. This double-blind study and clinical trial was performed on 60 patients with class I and II ASA after Tonsillectomy surgery. In this study, patients were divided in two groups of 30 members and were put under similar Anesthesia procedures. After the anesthesia procedure, the level of pain in patients were determined in hours 1, 6, 12, and 24 after the surgery using the Verbal pain score (VPS) questionnaire. Data Analysis was performed using SPSS software version 21 and with the support of clinical trial studies such as K square; P 0.05). Results indicated that the topical injection of Bupivacaine in tonsillectomy provided better pain-relief compared to Ketamine.
