Comparison the effect of open and closed endotracheal suctioning systems on heart disrhythmia in mechanically ventilated patients

Nowadays، due to an increase in patients require intensive care، application of mechanical ventilation and endotracheal tube is necessary. In order to Keeping an open airway، endotracheal suctioning is necessary. Select the appropriate suction method can reduce the severe complications. The aim of this study is comparing the efficacy of open and closed suctioning on heart disrhythmia in mechanically ventilated patients. This semi experimental study was done on 40 patients admitted in the intensive care unit. Before and at various intervals after open and closed suctioning، heart rate and heart rhythm were recorded. Analyzed of data was done by SPSS 16، Fisher exact test & x2 score and P<0. 05 was considered significant. There was a statistically significant different on heart rate and heart Rhythm in different times after closed and open suction system. Closed suction system provides less impaired hemodynamic status of patients. So in order to care for mechanically ventilated patients، with heart disease open suction can be replaced by the closed suction system.
