BACKGROUND: Extensive efforts have been made toward reducing postoperative opioid use in children. In this study, we assessed whether propacetamol, or a nonsteroidal anti-inflammatory drug (NSAID), or their combination could effectively reduce opioid use in children after laparoscopic inguinal hernia repair. METHODS: This randomized, double-blind clinical trial included 159 children aged 6 months to 6 years. Children were allocated into 1 of the following 3 groups: group I was treated with 10 mg·kg−1 ibuprofen, group P was treated with 30 mg·kg−1 propacetamol, and group I + P was treated with both drugs in their respective concentrations. If the face–legs–activity–crying–consolability (FLACC) score was ≥4 during the postanesthesia care unit stay, 1.0 µg·kg−1 fentanyl was administered as a rescue analgesic. The number of patients who received rescue fentanyl in the postanesthesia care unit was defined as the primary outcome; this was analyzed using the χ2 test. The secondary outcomes included the FLACC and the parents’ postoperative pain measure (PPPM) scores until the 24-hour postoperative period. RESULTS: Among the 144 enrolled patients, 28.6% in group I, 66.7% in group P, and 12.8% in group I + P received rescue fentanyl in the postanesthesia care unit (P < .001). The highest FLACC score was lower in group I + P than in either group I or P (P = .007 and P < .001, respectively). Group I + P presented significantly lower PPPM scores than group P at 4 and 12 hours postoperative (P = .03 and .01, respectively). CONCLUSIONS: The use of ibuprofen plus propacetamol immediately following laparoscopic hernia repair surgery in children resulted in the reduced use of an opioid drug compared with the use of propacetamol alone.
