Summary

A randomized crossover clinical trial conducted in an Intensive Care Unit of the Hospital de Clinicas de Porto Alegre (HCPA) to compare the efficacy of the two techniques on the amount of aspirated pulmonary secretion and pulmonary mechanics: aspiration of the closed system following an expiratory pause with mechanical ventilator for 5 seconds (5-Second Expiratory Pause) and aspiration of the closed system following an expiratory pause with mechanical ventilator for 10 seconds (10-Second Expiratory Pause).

Detailed description

After randomization, all patients will be positioned in dorsal decubitus with the head elevated at 30 degrees and will be aspirated once with a closed suction system and with a vacuum of -40cm H2O. Hemodynamic and pulmonary parameters will be collected and recorded. One of the two techniques will be applied, according to randomization, and the outcomes measured. After two hours, hemodynamic and pulmonary parameters will be re-collected, and the second technique will be applied. The outcomes will be measured again.

Conditions

• Mechanical Ventilation

Interventions

Type	Name	Description
OTHER	5-Second Expiratory Pause	Patients on mechanical ventilation for more than 24 hours will be randomized for the first technique to be applied. This technique consists of closed system aspiration and expiratory pause with mechanical ventilator for 5 seconds. After randomization and before the application of the technique, all patients will be positioned in supine position with the headboard elevated at 30 degrees and will be aspirated once with closed aspiration system and with vacuum of -40 cm H2O.
OTHER	10-Second Expiratory Pause	Patients on mechanical ventilation for more than 24 hours will be randomized for the first technique to be applied. This technique consists of closed system aspiration and expiratory pause with mechanical ventilator for 10 seconds. After randomization and before the application of the technique, all patients will be positioned in supine position with the headboard elevated at 30 degrees and will be aspirated once with closed aspiration system and with vacuum of -40 cm H2O.
