Study on Ultrasound-Guided Lung Recruitment to Reduce Lung Complications After Total Laparoscopic Hysterectomy in Women with Obstructive Sleep Apnea

What this Trial Is About

Researchers are studying the lung-protective effects of ultrasound-guided lung recruitment maneuvers in female patients with obstructive sleep apnea OSA undergoing total laparoscopic hysterectomy. The study aims to compare different lung recruitment techniques and explore how measuring end-expiratory lung volume EELV helps assess their effectiveness in reducing postoperative pulmonary complications. Participants will be randomly assigned to one of three groups the sustained inflation recruitment maneuver group, the incremental positive end-expiratory pressure PEEP recruitment maneuver group, or the ultrasound-guided recruitment maneuver group. Each group receives a specific procedure involving adjustments to airway pressure and timing during surgery to improve lung function. The ultrasound-guided group uses lung ultrasound to target areas of reduced aeration and guide treatment. Throughout the study, lung ultrasound scores will be measured at five time points after intubation, after the first recruitment maneuver, after surgery, after the second recruitment maneuver, and 30 minutes after extubation. Additionally, lung volume changes using the EELV method will be recorded. These assessments help evaluate lung aeration and function. Participants safety and lung condition will be closely monitored during and after surgery, with the study expected to end by August 2026.
