Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 scheduled for abdominal laparoscopic surgery who are at increased risk of postoperative pulmonary complications.

Probably not a fit

Patients with severe chronic obstructive pulmonary disease, major previous lung surgery, or unstable hemodynamics may not benefit from this study.

What this trial studies

This clinical trial evaluates the effects of recruitment maneuvers and PEEP-guided ventilation using electrical impedance tomography (EIT) in patients undergoing abdominal laparoscopic surgery. It is a prospective, single-center, randomized controlled trial where participants will be divided into two groups: one receiving EIT-guided PEEP adjustments and regular recruitment maneuvers, and the other receiving standard ventilation with a constant PEEP. The study aims to assess regional ventilation, blood oxygenation, and pulmonary mechanics, as well as postoperative complications and hospital stay duration. The findings could help optimize ventilation strategies during surgery to enhance patient outcomes.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative pulmonary complications and improve recovery for patients undergoing laparoscopic surgery.

How similar studies have gone: Previous studies have shown promising results with EIT-guided ventilation strategies, indicating potential for success in this novel application.
