Raising the Bar: Multimodal Analgesia with Transdermal Lidocaine for Nuss Repair of Pectus Excavatum Decreases Length of Stay and Opioid Use

Intro: Pain management for minimally invasive (Nuss) repair of pectus excavatum (PE) is challenging, particularly as the judicious use of opioids has become a patient safety priority. Multi-modal pain management protocols are increasingly used, but there is limited experience using transdermal lidocaine patches (TLP) in this patient population. Methods: Pediatric anesthesiologists and surgeons in a children's hospital within a hospital designed a multi-modal perioperative pain management protocol for patients undergoing Nuss repair of PE (IRB00068901). The protocol included use of TLP in addition to other adjuncts such as methadone, gabapentin, and NSAIDS. Following initiation of the protocol charts were reviewed retrospectively, comparing outcomes before and after implementation of the protocol. Results: Forty-nine patients underwent a Nuss procedure between 2013 and 2022, 15 prior to initiation of the protocol and 34 after. Patient demographics and operative length were similar between the two groups. Average length of stay decreased from 4.7 to 3.3 days and reported opioid use at the time of the first outpatient post-op visit dropped from 60% to 24% (p < 0.05). Morphine milligram equivalents (MME) usage was decreased following implementation during hospital admission, at discharge, and at first post-operative visit (464 vs. 169,1288 vs. 218, and 214 vs. 56, respectfully, p < 0.05). There were no ED visits or readmissions <30 days related to post-operative pain. Conclusion: Post-operative opioid usage and hospital length of stay were decreased after initiation of the protocol. Transdermal lidocaine patches may be a helpful adjunct to minimize narcotic requirements after repair of pectus excavatum. (c) 2023 Elsevier Inc. All rights reserved.
