Using Electrical Impedance Tomography to Improve Breathing During Abdominal Laparoscopic Surgery
Impact of Recruitment Maneuvers and PEEP-guided Electrical Impedance Tomography on Regional Ventilation, Gas Exchange, and Pulmonary Mechanics in in Abdominal Laparoscopic Surgery Patients
This study tests if using a special breathing technique with electrical sensors can help patients breathe better during abdominal surgery compared to standard methods.

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.
Who should consider this trial
Good fit: Ideal candidates are adults over 18 scheduled for abdominal laparoscopic surgery who are at increased risk of postoperative pulmonary complications.
Not a fit: Patients with severe chronic obstructive pulmonary disease, major previous lung surgery, or unstable hemodynamics may not benefit from this study.
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 performed: Previous studies have shown promising results with EIT-guided ventilation strategies, indicating potential for success in this novel application.
