Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to evaluate whether the MetaNeb® System can effectively prevent and treat early postoperative atelectasis in adult patients admitted to ICU after esophagectomy for esophageal cancer.

The main question it aims to answer is: can the MetaNeb® system significantly reduce the lung ultrasound score (LUSS) indicating atelectasis on postoperative days 1 and 2? Participants will be randomly assigned to either the standard treatment or MetaNeb group, undergo lung ultrasound and electrical impedance tomography (EIT) assessments on postoperative days 1 and 2, receive at least 4 sessions of MetaNeb therapy on postoperative day 1 if in the intervention group, be monitored for oxygenation indices, ICU stay duration, incidence of mechanical ventilation, need for bronchoscopic intervention, and adverse events like pneumothorax.
