Conditions

Atelectases, Postoperative Pulmonary

Brief summary

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.

Interventions

DEVICEMetaNeb Therapy

Patients in the MetaNeb group receive at least 4 sessions of MetaNeb therapy on postoperative day 1 (each session includes cycles of CPEP and CHFO modes totaling 10 minutes).

BEHAVIORALStandard of care

Standard postoperative care, including guidance on coughing and expectoration, turning and back percussion, and early mobilization (getting out of bed for physical activity).
