Parecoxib versus tramadol for post-appendectomy pain.

ABSTRACT

Open uncomplicated appendectomy is known for low to medium degree of postoperative pain and a short hospital stay. Based on multimodal pain therapy, non-opioid analgesics have widely been a part in pain control. Parecoxib and tramadol have advantages over traditional opioids that are causing less nausea or vomiting, respiratory depression and sedation. As a result, the authors aimed to compare parecoxib and tramadol regarding quality of pain control after open appendectomy. Fifty patients, underwent open appendectomy with spinal anesthesia, were randomized to receive either parecoxib or tramadol (n = 25 each). Parecoxib 40 mg and tramadol 50 mg IV were administered twice, when closing the peritoneum and at 12 h later Doses of rescued meperidine for 24 h were recorded. Pain score, sedation, nausea or vomiting and satisfaction scores were assessed at 6, 12 and 24 h after operation. The mean rescued doses of meperidine were 4.6 +/- 10.9 and 18.6 +/- 21.0 mg in parecoxib and tramadol groups respectively (p = 0.005). There was a significantly higher pain score at 24 h (p = 0.01) and sedation score at 6 h (p = 0.003) in the tramadol group. Parecoxib provided a lower pain and sedation scores and lesser meperidine consumption than tramadol for post-appendectomy pain. IMPLICATION Parecoxib, as a primary analgesic, is better in analgesia and has less sedation than tramadolfor post-appendectomy pain.
