Lap surgery lung risk: new study tracks ventilator impact
NCT ID NCT07431242
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches how the breathing machine's settings during laparoscopic belly surgery may affect lung problems after surgery. Researchers will record machine data during surgery for 90 adults and check for complications like low oxygen or needing breathing help. No changes are made to patient care—just observation to learn more.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population consists of adult patients undergoing elective laparoscopic abdominal surgery under general anesthesia at a tertiary care center. All participants will receive routine intraoperative volume-controlled mechanical ventilation as part of standard clinical practice. The study will include patients meeting predefined eligibility criteria, and no protocol-based modifications to anesthetic or ventilatory management will be performed.
