First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if adding nitrous oxide (laughing gas) to standard sedation during GI endoscopy (like colonoscopy) could reduce side effects such as fatigue, mental fogginess, and nausea after the procedure. The study was designed for adults 18 and older undergoing these procedures. However, the study was withdrawn before enrolling any participants, so no results are available.
