Effect of lateral positioning on ventilation in patients with blunt thoracic injury during pressure support ventilation: the VICTORY study.

ABSTRACT:

Background

In patients with blunt thoracic injury requiring mechanical ventilation lateral positioning is routinely performed. Whether it modifies ventilation distribution and aeration is unclear.

Study design and methods

Patients receiving pressure support ventilation (PSV) were positioned 30 degrees on each side for 30 min. Electrical impedance tomography (EIT) was used to quantify the percentage of right and left ventilation. Secondary outcomes included right and left tidal volume and the modified lung ultrasound score. At baseline, patients were categorized according to ventilation distribution: symmetrical (right lung receiving 50-55% of total ventilation) or asymmetrical.

Results

Twenty-four patients were included (mean age 51 ± 20 years, 79% male) under median
