Not Applicable

Completed

• Conditions: Mucociliary Clearance Defect; Physical Disability
• Interventions: Other: Vibrocompression (VB); Other: Hyperinflation (HMV); Other: HMV+VB

• Registration Number: NCT02604082
• Lead Sponsor: Hospital de Clinicas de Porto Alegre

Brief Summary

Randomized clinical trial, conducted in the Intensive Care Unit of the Hospital de Clinicas de Porto Alegre from october 2011 until november 2015 .

Detailed Description

Objective: To compare the effectiveness of techniques: vibrocompression (G1), hyperinflation with mechanical ventilation (G2) vibrocompression + hyperinflation with mechanical ventilation (G3) in the amount of aspirated secretions, mechanical ventilator time, incidence of ventilator-associated pneumonia , reintubation tracheal and mortality in mechanical ventilator. Primary outcome: weight in grams of the aspirated secretions. Secondary outcome: hemodynamic and pulmonary parameters: heart rate, respiratory rate, mean arterial pressure, peripheral arterial oxygen saturation; peak inspiratory pressure, tidal volume; dynamic compliance ; mechanical ventilator time; reintubation tracheal; Incidence of ventilator-associated pneumonia and mortality in mechanical ventilator.

Arm && Interventions

Group	Intervention	Description
Vibocompression (VB)	Vibrocompression (VB)	Grup 1 - Vibrocompression: Is a physical therapy technique, that aims to clear the airways of patients on mechanical ventilation. Through the thoracic compression during expiration
Hyperinflation (HMV)	Hyperinflation (HMV)	Grup 2 - Hyperinflation with Mechanical ventilator: Is a physical therapy technique, that aims to clear the airways of patients on mechanical ventilation. Through the increase in inspiratory pressure ventilator .
HMV+VB	HMV+VB	Grup 3 - Hyperinflation with mechanical ventilator and vibrocompression:Is a physical therapy technique, that aims to clear the airways of patients on mechanical ventilation. Through the thoracic compression during expiration and the increase in inspiratory pressure ventilator.
