Comparison of Three Technical Airway Clearance in Mechanical Ventilated Patients
Comparison of Three Technical Airway Clearance in Mechanical Ventilated Patients
Randomized clinical trial, conducted in the Intensive Care Unit of the Hospital de Clinicas
 de Porto Alegre from october 2011 until november 2015 .
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.
Inclusion Criteria:

 -  In mechanical ventilation for a period of 24-72 h

 -  End-expiratory pressure (PEEP) lower 10 cm of water.

 -  Lower noradrenaline doses of 0.5mg / kg / minute for an average greater than or equal
 blood outstrips 60 mmHg.

 Exclusion Criteria:

 -  Pneumothorax and hemothorax undrained

 -  Subcutaneous emphysema

 -  Osteoporosis

 -  Acute respiratory distress syndrome - (ARDS)

 -  Fractures of ribs

 -  Obese ( BMI greater than 35)

 -  Mechanical ventilator with higher peak pressures 40 cm of water.
