Effects on Postoperative Gastrointestinal Motility After Neuromuscular Blockade Reversal With Sugammadex Versus Neostigmine/Glycopyrrolate in Colorectal Surgery Patients

Background: Neuromuscular blockers (NMBs) used during surgery have historically been reversed with acetylcholinesterase inhibitors and anticholinergic agents, which can slow gastrointestinal motility. Sugammadex (SUG) provides NMB reversal with minimal effects on gastrointestinal motility. Objective: The purpose of this study was to determine if SUG for reversal of NMB is associated with decreased time to first bowel movement (BM) following laparoscopic colorectal surgery. Methods: A retrospective cohort analysis divided 224 patients undergoing laparoscopic colorectal surgeries based on whether they received SUG or a combination of neostigmine and glycopyrrolate (NG) for NMB reversal. The primary outcome was time (in hours) from NMB reversal until first recorded BM. Secondary end points were postoperative ileus, postoperative nausea and vomiting, prevalence of residual NMB, and hospital length of stay. The relationship between NMB reversal agent and outcomes were analyzed using multivariable linear regression and Cox proportional hazards model. Results: There were 128 patients who received NG and 96 who received SUG. Time to first BM was faster in the SUG group by 11.7 hours (P = 0.004). SUG maintained the effect in a multiple regression model (P = 0.012). A Cox Proportional Hazards regression model found 50% increased odds of a BM across time for the SUG group (P = 0.003). No adverse effects were noted. Conclusion and Relevance: This represents the first report demonstrating faster return of BM following colorectal surgery with SUG when compared with NG. Application of these data may add another tool to enhance recovery after colorectal surgery.
