What this trial studies

This clinical trial aims to assess the effectiveness of various ultrasound-guided preventive measures for postoperative lung atelectasis in patients undergoing elective abdominal surgeries. The study will utilize a prospective randomized blinded design to evaluate interventions such as positive end-expiratory pressure (PEEP), lung recruitment maneuvers (RM), and restrictive fluid management (RF). By monitoring lung function through ultrasound, the trial seeks to identify the best combination of these measures to reduce the incidence of lung collapse after surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 30-60 with ASA physical status I or II, scheduled for elective abdominal surgeries, and with a BMI under 40.

Not a fit: Patients with a history of chest disorders, psychiatric disorders, or those classified as ASA physical status III or higher may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the occurrence of postoperative lung atelectasis, leading to improved recovery and outcomes for patients undergoing abdominal surgery.

How similar studies have performed: While there have been studies exploring preventive measures for postoperative lung atelectasis, the specific use of ultrasound evaluation in this context is relatively novel.
