Study summary

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

Read the 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.

  • Active comparator
    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 .

    Other: Hyperinflation (HMV)

  • Experimental
    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.
