Evaluation of Postoperative Efficacy and Safety of Celecoxib in Children Hospitalized After Adenotonsillectomy.

Objective: The choice of optimal analgesia following an adenotonsillectomy is a clinical issue because of the risk of respiratory depression and bleeding. The objective of this study was to assess the effect of celecoxib on opioid use and pain scores in children hospitalized after adenotonsillectomy and to document its adverse effects.

Methods: This retrospective study was conducted in a tertiary care pediatric hospital. We compared a group of subjects aged 1 to 17 years who were prescribed celecoxib and opioids between January 2017 and June 2020 following an adenotonsillectomy during a 3-day or less hospitalization to a group of matched controls for sex, age, and length of stay who were prescribed opioids.

Results: A total of 228 patients were identified (76 in the celecoxib + opioids group, 152 in the control group). Opioid use, in oral morphine equivalent daily dose, was lower in the celecoxib + opioids group at 0 to 24 hours of hospitalization (0.15 vs 0.20 mg/kg/day, p = 0.05). Initiating celecoxib within 24 hours of surgery (n = 60) significantly reduced opioid requirement for up to 48 hours compared with controls (0-24 hours: 0.12 vs 0.20 mg/kg/day, p = 0.002; 25-48 hours: 0.02 vs 0.09 mg/kg/day, p = 0.001). A shorter length of stay was observed for patients receiving celecoxib + opioids during the first 24-hour post--operative period (27 vs 32 hours, p = 0.01). With celecoxib use, no significant change in pain scores and occurrence of adverse effects including bleeding was found.

Conclusions: Using celecoxib early after an adenotonsillectomy has reduced both opioid use and duration of hospital stay without increasing adverse effects or bleeding.
