Brief summary

The objective of this study is to assess if not requiring patients to spontaneous void prior to discharge from the post-anesthesia care unit (PACU) will results in shorter lengths of stay in the post-anesthesia care unit without increasing hospital readmissions or emergency room visits.

Detailed description

This study will be a prospective clinical trial, in which 100 anorectal surgery patients will be randomly assigned to a control (spontaneous void) or experimental (no void group). The spontaneous void group will include 50 patients who will be required to void spontaneously after anorectal surgeries. The no void group will be 50 patients who will be discharged home from the PACU once they meet ambulatory surgery center discharge criteria per hospital guidelines. Patients requiring anorectal surgeries will be consented to take part in the study during the preoperative outpatient office visit. A post-operative phone call will be made by designated study personnel to participants on post-op day 30 using a study questionnaire to assess re-admission and emergency room visits.

Interventions

OTHERNo Void

Currently the protocol at The Ohio State University Hospital requires voiding spontaneously prior to discharge from the PACU. Our intervention group will be discharged home without having to void spontaneously as a discharge criteria.
