Abstract

Background: The Nuss procedure has provided a minimally invasive surgical solution for pectus excavatum with excellent long-term outcomes. However, opioid avoidance, cost reduction, and length of stay (LOS) still offer room for improvement. The focus of this study is to identify the impact of Bupivacaine liposome injectable suspension (Exparel) on outcomes. Methods: A retrospective review at a Pediatric specialty hospital from October 1, 2014 to December 31, 2019 was performed. All patients underwent a Nuss procedure (n = 19) for pectus excavatum. The cohort comprised a control group that did not use liposomal Bupivacaine (Standard, n = 9) and an interventional group that received liposomal Bupivacaine (n = 10). Nonparametric Wilcoxon rank-sum tests and chi-squared or Fisher's exact tests were used to assess significance (P < .05). Results: Overall, the entire population was 68.4% male and had an average age of 15 years. There was a significant difference between the Standard and Liposomal Bupivacaine groups for total cost ($60,746 versus $13,289), total Morphine Milligram Equivalents (MME) (282 versus 76.8 MME) and Epidural Catheter usage (100% versus 0%). There was also a significant difference between groups for LOS (5.00 days versus 3.00 days) and Foley catheter usage (100% versus 20%). Conclusions: There is a significant impact of liposomal Bupivacaine usage on epidural catheter avoidance and opioid administration correlating with a significantly decreased total cost and decreased LOS. While more study is necessary, liposomal Bupivacaine for Nuss procedure offers improvement of postoperative patient outcomes and drastic cost savings.
