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 accomplished with complications such as severe hypoxia and significant cardiovascular disorders 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 suction on the pattern of heart rate and arterial blood oxygen saturation. Methods: In this cross over clinical trial study performed during 1386-87 in critical care units of Artesh hospitals, 60 patients who were connected to the ventilator were selected. Open and closed suction techniques 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 was used. Results: There was a significant different on heart rate and oxygen saturation in different times after closed suction system and open suction system (p< 0.0001). These differences in different periods after the open suction method was more visible than closed but there was no change in cardiac rhythm in both open and closed suction methods (p>0.05). Conclusi on: Open and closed suction methods are effective on heart rate and arterial blood oxygen saturation and it is suspected that closed suction method makes less changes in patient hemodynamic status. |
