Abstract

Objective: To evaluate the effect of ventilator-associated pneumonia prevention of closed versus open suction systems in traumatic brain injury patients who underwent machine ventilation. Method: Research method is randomized controlled clinical trial. The participated patients were diagnosed with traumatic brain injury alone, GSC ≤8 points, underwent mechanical ventilation for more than 48 hours with indication for surgery or not, divided into 2 groups. Group 1 was the group of patients using the closed suction system and group 2 was the patients using the open suction system. The participating patients were monitored for ventilator-associated pneumonia daily until weaned the ventilation and discharged from the ICU. Results: In 101 patients participating in the study, 49 patients were installed with an open suction system and 52 patients were installed with a closed suction system. The rate of ventilator-associated pneumonia of the patients participating in the study was 44.5%, of which 55.1% in the open suction group and 34.6% in the closed suction group, the difference between the two groups was statistics significant with p=0.038<0.05. In addition, the closed suction system group also had less mechanical ventilation time and recovery time. There were no differences in the bacteria stain causing ventilator-associated pneumonia in the two groups. Conclusion: The closed suction system helps to reduce the rate of ventilator-associated pneumonia, reduce the number of days of mechanical ventilation and resuscitation.
