Comparison of Topical and Subcutaneous Bupivacaine Infiltration with Subcutaneous Ketamine on Postoperative Pain in Total Abdominal Hysterectomy

INTRODUCTION: Hysterectomy is one of the most common surgical procedures. Problems such as severe pelvic pain, irregular or heavy bleeding and uterine cancer from those that may be used to treat them no choice but to remove the uterus by surgery. Abdominal pain after abdominal hysterectomy, the most common complaints of patients undergoing this type of surgery is considered. AIM: This study aimed to compare the effects of bupivacaine into the subcutaneous tissue and skin ketamine for pain control after surgery in patients undergoing abdominal hysterectomy was performed under general anesthesia. METHODS: This study is a randomized, double-blind clinical trial involving 99 women scheduled for TAH referred to tertiary centers was performed. Group A: 5 mL of 0.25% bupivacaine into the subcutaneous tissue and, Group II: 100 mg ketamine skin and subcutaneous tissue with cc5 volume injection, groups of three: cc5 distilled water was injected into the subcutaneous tissue and. The average duration of analgesia and pain and pain score were recorded. RESULTS: The average duration of analgesia in group K 65.1±8.8, in the bupivacaine group 65.4±8.7 and in the placebo group 57.6±5.5, which, according to P Value≤0.01 is a significant difference between the three groups were observed, so that the pain in the placebo group for a significant period of ketamine and bupivacaine groups is lower, while that between ketamine and bupivacaine in terms of the average duration of analgesia was no significant difference not. CONCLUSION: The results of our study indicate that the use of bupivacaine and ketamine effective in reducing postoperative pain in patients undergoing abdominal hysterectomy tissue and further doses of ketamine and bupivacaine single dose resulted in a significant reduction of postoperative pain patients were compared to the placebo group.
