Application of parecoxib in post-uvulopalatopharyngoplasty analgesia

摘要

Objective To investigate the postoperative analgesic effects of parecoxib for uvulopalatopharyngoplasty (UPPP). Methods Patients with obstructive sleep apnoea syndrome who underwent UPPP were randomly divided into two groups. In group A, the incision-local block was performed with 5?ml of 0.5% ropivacaine injected subcutaneously before the end of surgery, then 20?ml of physiological saline was injected intravenously every 12?h for 2 days. In group B, in addition to the incision-local block, 40?mg parecoxib was injected intravenously 30?min before the end of UPPP and 40?mg parecoxib was injected intravenously every 12?h for 2 days. Postoperative pain was measured using a visual analogue scale (VAS). Adverse reactions were recorded. Results A total of 40 patients were randomized (n?=?20 per group). Under resting conditions, the mean?±?SD VAS pain scores were significantly higher in group A compared with group B at 24?h and 48?h after UPPP (24?h 4.0?±?0.8 versus 2.6?±?0.6; 48?h 3.8?±?0.7 versus 2.4?±?0.5; respectively). Under swallowing conditions, the mean?±?SD VAS pain scores were significantly higher in group A compared with group B at 8?h, 24?h and 48?h after UPPP. Postoperative adverse reactions were similar in the two groups. Conclusion Intravenous parecoxib combined with incision-local ropivacaine provided effective postoperative analgesia for patients with obstructive sleep apnoea syndrome, undergoing UPPP.
