New lung maneuver may shield sleep apnea patients during surgery
NCT ID NCT07362680
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a lung-protective technique during surgery for women with obstructive sleep apnea (OSA) undergoing total laparoscopic hysterectomy. The approach uses ultrasound to guide lung recruitment maneuvers, aiming to reduce postoperative lung complications like collapsed lung tissue. About 90 participants will be enrolled to see if this method improves lung function after surgery.
