The purpose of this research study is to see the outcome of Sugammadex versus Neostigmine with Glycopyrrolate in colorectal surgery as it relates to its effects on post-surgical time (in hours) to first bowel movement and tolerance for solid food (GI-2 recovery) following bowel resection surgery

Official Title

Sugammadex VS Neostigmine and Glycopyrrolate Reversal of Neuromuscular Relaxation For Time to Return of Bowel Function After Bowel Resection: Prospective, Randomized, Triple-blinded Clinical Trial For Quality Improvement


Neuromuscular blocking agents are essential during surgical procedures to paralyze the body to avoid unnecessary movement during surgery. There are various medications, such as Sugammadex that are later used to reverse the effects of the neuromuscular blockade. The U.S. performs approximately 320,000 colectomies per year for benign and malignant conditions such as Ulcerative Colitis (UC). Bowel resection surgery removes a portion of small or large intestine. Currently, there is little available prospective outcomes data regarding the use of Sugammadex versus Neostigmine with Glycopyrrolate in colorectal surgery as it relates to its effects on post-surgical time (hour) to first bowel movement and tolerance for solid food (aka GI-2 recovery) following bowel resection surgery. The study team will be conducting a randomized triple-blind study (patient's assigned group is hidden from the patient, provider, and research team). Randomization is created by using an electronic randomizer. Upon consent, the patient's assignment (per the randomizer) will be submitted to the Investigational Drug Service (IDS) Pharmacy by a department employee with no direct patient interaction.
