Postoperative pain management using an intravenous combination of ibuprofen and acetaminophen compared with acetaminophen alone after thyroidectomy: A prospective randomized controlled trial.

ABSTRACT

BACKGROUND: Multiple medications are more effective than single agents for postoperative pain management. We investigated the analgesic effects of an intravenous combination of acetaminophen and ibuprofen immediately after thyroidectomy. METHODS: In this double-blind clinical trial, 62 patients who underwent thyroidectomies were randomized to either the treatment (1000 mg acetaminophen, 300 mg ibuprofen) or control (1000 mg acetaminophen) group. Postoperative pain intensity was assessed using the visual analog scale (VAS) 0, 15, and 30 min after recovery room admission. Opioid rescue consumption was also recorded. RESULTS: The VAS scores were significantly lower in the treatment than in the control group 15 [3 (2-4.3) vs. 5 (3-6); p = 0.015] and 30 [3 (2-4.3) vs. 4 (3-5); p = 0.018] min after recovery room admission, as were the opioid rescue dose requirements (p = 0.033). CONCLUSIONS: Combined intravenous acetaminophen and ibuprofen may be better than acetaminophen alone for immediately acute postoperative pain after thyroidectomy.
