Aims: Many patients need special care, and endotracheal tube and the use of mechanical ventilation is essential. This type of airway leads to mucosa stimulation and production of mucus. Suctioning is accociated with complications such as severe hypoxia and significant cardiovascular disorders. Therefore, selecting the least dangerous way of endotracheal tube suction can reduce severe complications. This study compared the effect of two open and closed methods of suctioning on heart rate pattern and arterial blood oxygen saturation. Methods: This crossover clinical trial study performed during 2008-2008 in critical care units of army selected hospitals, 60 patients who were connected to ventilator were selected. Open and closed suction techniques were carried on samples and heart rate patterns and arterial blood oxygen saturation was measured in patients before and several times after each type of suction and was compared. For analysis of data the paired t-test and ANOVA and SPSS 17 software were used. Results: There was a significant difference in heart rate and oxygen saturation in different times after closed suction system and open suction system (p<0.0001). The difference was more obvious in different periods after open suction method, but there was no change in cardiac rhythm in both open and closed suction methods (p>0.05). Conclusion: Open and closed suction methods are effective on heart rate and arterial blood oxygen saturation and it is suspected that closed suction method causes less changes in patient’s hemodynamic status.
