Abstract

Endotracheal suctioning is one of the most important care that done continuously in patient with Brain injuries. Type of suctioning affected on the hemodynamic status of patients, this study was performed with the aim of comparing changes in Arterial Blood Oxygen Saturation and Occurrence of Cardiac Dysrhythmia in head trauma patients with open and closed suction. In this cross-over clinical trial study, 88 patients who under mechanical ventilator were enrolled randomly divided into two groups. Closed and open suctioning each done for each patient and changes on Arterial Blood Oxygen Saturation and Occurrence of Cardiac Dysrhythmia at intervals before, during. Immediately, five, ten and fifteen minutes by using paired t-test, ANOVA with repeated data and Fisher's exact test were performed by software SPSS version 22. 88 patients with ranging from 15 to 45were enrolled. 68% of patients were male. The most cause of head injury was car accident (75%) that the most frequent CT scan findings associated with intraventricular hemorrhage (22%). The occurrence of Cardiac Dysrhythmia and changes on Arterial Blood Oxygen Saturation was more in open method of endotracheal suctioning. There were significant relationships between Arterial Blood Oxygen Saturation and occurrence of Cardiac Dysrhythmia in Multiple time intervals with type of suctioning.(p<0.001). According to the findings, to reduce Arterial Blood Oxygen Saturation and incidence of Cardiac Dysrhythmia due to endotracheal suctioning, the use of closed suction in the intensive care unit is recommended.
