Study Summary
The purpose of this study is to evaluate the pain control, patient satisfaction, and efficiency of nitrous oxide used for anesthesia during in-office gynecologic procedures compared to IV sedation. IV sedation for office-based gynecology procedures provides effective anesthesia but requires a recovery time, IV placement, and a ride provided for the patient. Nitrous oxide can be a viable alternative to IV sedation while also reducing recovery time and omitting the need for an IV, NPO status, and a ride home.
Primary Outcome
Post procedure, patients will be asked to rate their pain using the VASscale, with 0 indicating no pain, to 10 indicating worst possible, unbearable, excruciating pain.
Interventions
- DRUG Nitrous oxide
- DRUG IV Sedation
