Comparison of the efficiency of oral Etoricoxib versus intravenous Fentanyl on post operative Pain in curettage under TIVA: A randomized controlled trial
Fractional Curettage is the most widely used for diagnostic and treatment abnormal uterine bleeding. The patient categorize post-operative pain as mild to moderate. Therefore, the effective analgesic added on intraoperative and post-operative is the most important factor in patient's satisfaction, patient well co-operation, shortness time of operation, decrease unpleasant symptoms and rapid recovery. However, there are many anesthetic technique that can be used to relive pain in the operation such as local anesthesia, total intravenous anesthesia, regional anesthesia or oral analgesic drugs. Intravenous Fentanyl is an short acting opioid. It has a fast onset of action within 2 minutes and short duration of action 30-60 minutes. Respiratory depression, hypotension and bradycardia are adverse effects that might delayed discharge especially in one day surgery e.g. fractional curettage. Etoricoxib is an oral COX-2 specific inhibitor which can be used to relieve the pain. The onset of analgesia can be occurred within 24 minutes which peak plasma level within 60 minutes. There are many empirical evidences to support the results of post-operative pain after used oral Etoricoxib or intravenous Fentanyl. However, there are less evidences to support efficiency of oral Etoricoxib versus intravenous Fentanyl on post-operative Pain in fractional curettage under TIVA
