Effects of Ultrasound-guided Recruitment Manoeuvres on Postoperative Pulmonary Complications in OSA Patients Undergoing Total Laparoscopic Hysterectomy

Effects of Ultrasound-guided Recruitment Manoeuvres on Postoperative Pulmonary Complications in OSA Patients Undergoing Total Laparoscopic Hysterectomy

This study aims to evaluate the lung-protective effects of ultrasound-guided lung recruitment maneuvers in patients with OSA undergoing total laparoscopic hysterectomy and to explore the efficacy of EELV measurement in assessing the effectiveness of these maneuvers.

Inclusion Criteria:

• Age ≥ 18 years;
• Scheduled for elective total laparoscopic hysterectomy;
• American Society of Anesthesiologists (ASA) I to III;
• BMI > 28 kg/m²;
• STOP-BANG score ≥ 3.

Exclusion Criteria:

• Abnormal findings on preoperative chest X-ray or CT, such as atelectasis, pneumothorax, thoracic deformity, pleural effusion, or neuromuscular diseases;
• Pre-existing severe pulmonary diseases;
• Severe cardiac arrhythmias or a history of cardiac surgery;
• Allergy to any medications used in the study.
