Opioid-free Pain Management after Cleft Lip Repair

Abstract

Background: Side effects of opioid pain management after surgical repair of cleft lips are numerous and affect postoperative course. We compared opioid versus opioid-free pain management regimens for infants who underwent cleft lip repair to evaluate the impact on postoperative recovery. Methods: Cleft lip repairs at our institution from December 2016 to February 2021 were retrospectively reviewed, comparing patients who received opioids to patients receiving a nonopioid pain control regimen. Data collected include length of stay, oral morphine equivalents (OME) received on day of surgery (DOS)/postoperative day (POD) 1, time to and volume of first oral feed, and Face/Legs/Activity/Cry/Consolability (FLACC) scores. Results: Seventy-three infants were included (47 opioid and 26 nonopioid). The opioid group received average 1.75 mg OME on DOS and 1.04 mg OME on POD1. Average DOS FLACC scores were similar between groups [1.57 ± 1.18 nonopioid versus 1.76 ± 0.94 (SD) opioid; P = 0.46]. Average POD1 FLACC scores were significantly lower for the nonopioid group (0.73 ± 1.05 versus 1.35 ± 1.06; P = 0.022). Median time to first PO (min) was similar [178 (interquartile range [IQR] 66–411) opioid versus 147 (IQR 93–351) nonopioid; P = 0.65]. Median volume of first feed (mL) was twice as high for the nonopioid group [90 (IQR 58–120) versus 45 (IQR 30–60); P = 0.003]. Conclusions: Nonopioid postoperative pain management was more effective than opioids for pain management in infants after cleft lip repair, as evidenced by FLACC scores and increased volume of the first oral feed.
