Abstract
Objective
To investigate whether the addition of intrapulmonary percussive ventilation to the usual chest physiotherapy improves gas exchange and lung mechanics in tracheostomized patients.
Design and setting
Randomized multicenter trial in two weaning centers in northern Italy.
Patients and participants
46 tracheostomized patients (age 70 ± 7 years, 28 men, arterial blood pH 7.436 ± 0.06, PaO2/FIO2 238 ± 46) weaned from mechanical ventilation.
Interventions
Patients were assigned to two treatment groups performing chest physiotherapy (control), or percussive ventilation (IMP2 Breas, Sweden) 10 min twice/day in addition to chest physiotherapy (intervention).
Measurements and results
Arterial blood gases, PaO2/FIO2 ratio, and maximal expiratory pressure were assessed every 5th day for 15 day. Treatment complications that showed up in 1 month of follow-up were recorded. At 15 days the intervention group had a significantly better PaO2/FIO2 ratio and higher maximal expiratory pressure; after follow-up this group also had a lower incidence of pneumonia.
Conclusions
The addition of percussive ventilation to the usual chest physiotherapy regimen in tracheostomized patients improves gas exchange and expiratory muscle performance and reduces the incidence of pneumonia.
