What this trial studies

This clinical trial investigates a WashIn/WashOut procedure aimed at preventing agitation during recovery from inhalational anesthesia with sevoflurane. Agitation is a common complication that can lead to longer recovery times and increased risk of postoperative delirium and cognitive dysfunction. The study will involve adult patients undergoing planned open abdominal surgery under general anesthesia. Participants will be monitored for agitation levels and other postoperative outcomes following the intervention.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are scheduled for open abdominal surgery and will receive general anesthesia.

Not a fit: Patients with mental disorders, neurological conditions, or those on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this procedure could significantly improve recovery experiences and outcomes for patients undergoing surgery.

How similar studies have performed: While there have been attempts to address postoperative agitation, this specific approach is novel and has not been extensively tested in prior studies.
