Comparison of Protective Manual Hyperinflation With Current Methods in Ventilated Acute Trauma Patients: a Randomized Controlled Trial
Current evidence in mechanical ventilation supports a "protective lung strategy" that is,
smaller tidal volumes and prevention of loss of positive end expiratory pressure (PEEP).
There is concern that manual hyperinflation (MHI) may conflict with this strategy and cause
volutrauma and atelectrauma potentially leading to biotrauma.
This single-blinded randomized study aims to compare two methods of manual hyperinflation
(protective - moderate tidal volumes with positive end expiratory pressure) and
non-protective (large tidal volume and no positive end expiratory pressure) in ventilated
acute trauma patients, to investigate the effect on inflammatory markers, lung compliance,
oxygenation and sputum volume.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment
