Narcotic Utilization After Cleft Lip Repair: Does Local Anesthetic Choice Matter?

To analyze whether the choice of intraoperative local anesthetic for cleft lip repair is associated with the amount of perioperative narcotic utilization. Retrospective cohort study. Hospitals participating in the Pediatric Health Information System. Primary cleft lip repairs performed in the United States from 2010 to 2020. Local anesthesia injected—treatment with lidocaine alone, bupivacaine alone, or treatment with both agents. Perioperative narcotic administration. During the study interval, 8954 patients underwent primary cleft lip repair. Narcotic utilization for unilateral ( P < .001) and bilateral ( P = .004) cleft lip repair has decreased over the last 5 years. Overall, 21.8% (n = 1950) of infants were administered perioperative narcotics for cleft lip repair, such that 14.3% (n = 1282) required narcotics on POD 0, and 7.2% (n = 647) required narcotics on POD 1. In this study, 36.5% (n = 3269) patients received lidocaine, 22.0% (n = 1966) patients received bupivacaine, and 19.7% (n = 1762) patients received both local anesthetics. Administration of any perioperative narcotic was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only lidocaine ( P = .001, 17.5% vs 21.7%) or only bupivacaine ( P < .001, 17.5% vs 22.9%). Narcotic utilization on the day of surgery was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only lidocaine ( P < .001, 11.5% vs 15.1%) or only bupivacaine ( P = .004, 11.5% vs 14.6%). Narcotic utilization on the first postoperative day was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only bupivacaine ( P = .009, 5.9% vs 8.1%). Conclusions In children undergoing cleft lip repair, local anesthetic combination of lidocaine and bupivacaine is associated with decreased perioperative narcotic use compared to lidocaine or bupivacaine alone.
