Segmental Lung Recruitment: a Randomized Controlled Trial
Sponsor: Clinical Hospital Center Rijeka
Summary
This study compares two ways of reopening collapsed parts of the lung in patients on a ventilator. In one group, doctors use a small camera (bronchoscope) to guide air pressure directly to the blocked part of the lung. In the other group, increased air pressure is applied to the whole lung using the ventilator. Patients are carefully monitored to ensure safety.

Segmental lung recruitment
Patients will undergo bronchoscopy-guided targeted segmental lung recruitment via endobronchial blocker. Flexible bronchoscope will be introduced through the endotracheal tube and advanced under direct visualization to the affected lung segment. The endobronchial blocker will be positioned to temporarily occlude the segmental bronchus, creating a closed system. Sustained positive pressure of 30 cmH₂O will be applied directly to the atelectatic segment for 30 minutes, while standard ventilator settings will be maintained for the remaining lung tissue.
Conventional lung recruitment
Patients in the control group received standard recruitment maneuvers consisting of continuous positive airway pressure (CPAP) of 40 cmH₂O applied to the entire respiratory system for 40 seconds. This approach represents the conventional recruitment strategy used in clinical practice.
