Brief Summary

Mechanical ventilation (MV) is used to reduce work and reverse or prevent fatigue of the respiratory muscles, decrease oxygen consumption and maintain gas exchange. In addition to the benefits given to patients undergoing MV, there is a high risk of accumulating bronchial secretions, related to pathology and / or therapeutic intervention. Pulmonary hyperinflation is widespread in patients in intensive care centers (ICUs) as a bronchial hygiene therapy, being used in 40% of 64 Australian ICUs as demonstrated by Dennis et al., Through contact with physical therapists. Mechanical hyperinflation associated with tracheal aspiration is able to increase the amount of secretion aspirated when compared to isolated aspiration in patients undergoing mechanical ventilation. To assess whether the pulmonary hyperinflation maneuver with the mechanical ventilator, compared to isolated tracheal aspiration, increases the removal of secretions. To evaluate whether the use of the pulmonary hyperinflation maneuver in the mechanical ventilator is hemodynamically stable through the collection in two moments of the variables of heart rate (HR), mean arterial pressure (MAP), peripheral saturation (SpO2), respiratory rate (RF) that will be analyzed from the postoperative unit's multiparametric monitor. Evaluate the change in respiratory mechanics through collection in two moments after the mechanical hyperinflation technique through dynamic compliance (Cdyn), tidal air volume (VAC), peak pressure (Ppico). The population will consist of patients from the Post-Operative Unit (UPO), from the Institute of Cardiology, of both sexes, over 18 years old, mechanically ventilated and the sample consisting of 50 individuals. These will be submitted to the use of the pulmonary hyperinflation maneuver in the mechanical ventilator. Randomized crossover clinical trial.

Study Arms (2)

GROUP CONTROL

NO INTERVENTION

For basal aspiration, the patient will be placed in the supine position with the head elevated at 30º, will be submitted to a single aspiration with a size 12 probe (Mark Med), with a vacuum adjusted to -40cmH2O of pressure, with basic asepsis care being maintained for performing the technique. In the control group, patients will be ventilated for 1 minute with 100% inspired oxygen (FiO2), followed by three aspirations for 15 seconds and with an interval of 30 seconds.

INTERVENTION GROUP

ACTIVE COMPARATOR

For basal aspiration, the patient will be placed in the supine position with the head elevated at 30º, will be submitted to a single aspiration with a size 12 probe (Mark Med), with a vacuum adjusted to -40cmH2O of pressure, with basic asepsis care being maintained for performing the technique. In the participants of the intervention group, the calculation of the ideal tidal volume of each patient will be performed, after which they will be positioned in the supine position, the headboard elevated to 30º in assisted pressure-controlled ventilatory mode, increasing 10 cmH2O in inspiratory pressure and in assisted ventilation mode. -controlled by volume, we will increase 50% of the tidal volume for a period of 10 minutes, with Ppeak not exceeding 40 cmH2O and drive pressure not exceeding 15 cmH2O in both ventilation modes, and then a new aspiration in the same way as the control group.

Other: MECHANICAL PULMONARY HYPERINFLUATION

Interventions

For basal aspiration, the patient will be placed in the supine position with the head elevated at 30º, will be submitted to a single aspiration with a size 12 probe (Mark Med), with a vacuum adjusted to -40cmH2O of pressure, with basic asepsis care being maintained for performing the technique. In the participants of the intervention group, the calculation of the ideal tidal volume of each patient will be performed, after which they will be positioned in the same way as baseline aspiration, in assisted-controlled pressure ventilation, increasing 10 cmH2O in inspiratory pressure and, in ventilatory mode. -controlled by volume, we will increase 50% of the tidal volume for a period of 10 minutes, observing the peak that cannot exceed 40 cmH2O in both ventilation modes, and then three aspirations will be performed for 15 seconds and with an interval of 30 seconds.

CROSSOVER
Model Details: This is a randomized crossover clinical trial in which the individuals selected for the study will be randomized to receive isolated tracheal aspiration (Control Group) and pulmonary hyperinflation through the mechanical ventilator associated with tracheal aspiration (Intervention Group). Randomization will be performed through the randomization.com website by a 1: 1 crossed block, allocating the patient to one of the groups and, after 24 hours, another technique will be performed. In addition, a control aspiration will be performed 2 hours before both techniques.
