AbstractIntroduction: Pectus excavatum is a common congenital anomaly in the pediatric population. During the postoperative period, pain control is one of the top priorities. As a result, multiple techniques for pain control have been developed, including thoracic epidural analgesia, multimodal analgesia (MM), and elastomeric pain pump (EPP) placement. The purpose of this study was to evaluate the effectiveness of pain control using EPP as an adjunct to MM after the minimally invasive repair of pectus excavatum (MIRPE). Methods: We identified all pediatric patients undergoing MIRPE from June 2017 to July 2018. MM was employed in all patients; some patients additionally received subpleural EPP as adjuncts to postoperative analgesia. We reviewed pain scores, length of stay, opioid use, and complications. Results: During the study period, a total of 62 patients were included. The study cohort was divided into 15 patients undergoing MM alone versus 47 patients undergoing subpleural EPP placement plus MM (EPP + MM). Median pain scores were lower in the EPP + MM group (2.9 versus 4.2, P < .05). There was a significant reduction of total inpatient opioid use in the EPP + MM group (357.6 mg versus 466.9 mg, P = .03). There was no difference in median length of stay or complications. We found no significant difference between subpleural versus subcutaneous placement of the infusion catheters. Conclusion: The use of subpleural EPP as an adjunct to MM is an effective way to reduce pain and opioid use after MIRPE without increased risk of complications. Type of Study: Retrospective study with comparison group.
