Brief summary

This study is intended to be a single-site, prospective, randomized, controlled study that intends to enroll a total of 230 patients undergoing laparoscopic cholecystectomy at Parkland Hospital. Patients will be randomized to receive either neostigmine or sugammadex for reversal of rocuronium-induced neuromuscular blockade. A standardized anesthetic protocol that is usual and customary for the type of operation the patient is having will be provided to the anesthesia teams of enrolled subjects. The remainder of the anesthetic care of the subject will not deviate from the standard of care. To account for protocol deviations and patient dropout, up to 250 randomization envelopes will be made and enrollment will continue until there are 230 completed enrollments.

Detailed description

Objective: To determine the incidence of postoperative urinary retention after reversal of rocuronium-induced neuromuscular blockade by neostigmine versus sugammadex in patients undergoing laparoscopic cholecystectomy. Hypothesis: Subjects who are reversed with sugammadex will have less postoperative urinary retention compared to subjects who are reversed with neostigmine.

Interventions

DRUGNeostigmine

Maintenance neuromuscular blockade with boluses of rocuronium. For reversal, neostigmine.

DRUGSugammadex

Maintenance neuromuscular blockade with boluses of rocuronium. For reversal, sugammadex

The count of participants with Postoperative Urinary Retention (POUR) of Sugammadex and Neostigmine Groups is being reported. POUR will be defined as: 1. Inability to spontaneously urinate and a bladder volume ≥ 300 mL 2. Postvoid residual \> 150 mL 3. Need for insertion of Foley catheter or straight catheter
