The effect of intravenous ketoprofen on postoperative epidural sufentanil analgesia in children.

UNLABELLED

We compared the effect of IV ketoprofen and placebo as an adjuvant to epidural sufentanil analgesia after major surgery. We used a prospective, randomized, double-blinded, placebo-controlled, parallel-group study design in 54 children aged 1-15 yr who received a standardized anesthetic. Either IV ketoprofen or saline was administered in addition to an epidural sufentanil infusion, which was adjusted as required clinically. The study drug infusions were discontinued when pain scores were <3 on 0-10 scale for 6 h at a sufentanil infusion rate of 0.03 microg x kg(-1) x h(-1). Children in the ketoprofen group had a better analgesic effect, as shown by decreased need for sufentanil (mean [10th-90th percentiles] 8.3 [3.1-15.1] microg/kg vs 12.5 [6.2-18.9] microg/kg; P = 0.002) and earlier possibility to discontinuation of the epidural sufentanil (11 [46%] vs 3 [13%]; P = 0.014) before the end of the 72-h study period. In the ketoprofen group, median (range) pain scores were lower during activity at 24 h (2 [0-5] vs 5 [0-7]; P = 0.01) and at 72 h (0 [0-3] vs 2 [0-6]; P = 0.033), and fewer children had inadequate pain relief during activity at 24 h (0 vs 5; P = 0.037). Children who received ketoprofen required fewer infusion rate adjustments (12 [4-20] vs 17 [6-42]; P = 0.016). In the ketoprofen group, the incidence of desaturation (1 [4%] vs 6 [26%]; P = 0.035) and fever (3 [12%] vs 11 [48%]; P = 0.008) was less than that in the placebo group. We conclude that ketoprofen improved postoperative pain in children.

IMPLICATIONS

We compared the effect of the IV nonsteroidal antiinflammatory drug ketoprofen versus placebo as adjuvants to epidural opioid analgesia with sufentanil. The continuous IV nonsteroidal antiinflammatory drug improved pain after major surgery in children receiving an epidural opioid. Although ketoprofen reduced epidural sufentanil requirements, the incidence of opioid-related adverse effects was not changed.
