The effect of standard and routine endotracheal suctioning on hemodynamic indexes of patients admitted to the intensive care unit of AJA selected hospital

Suctioning the airways through an endotracheal tube is an important intervention to manage patients under mechanical ventilation, which is usually performed by nurses and if not accomplished properly, it can cause lots of side-effects.
The aim of this research was to determine the effects of standard and routine endotracheal suctioning on hemodynamic indexes of patients admitted to intensive care unit.
This was a clinical trial conducted at Besat hospital in Tehran in 2015. After preparing the instruction of standard suction by the researcher and validity confirmation, standard suction (by researcher) , and in the second turn routine suction (by the nurse of patient) , or conversely was performed for 36 patients considering their needs, randomly by tossing coin. HR, O2Sat and PIP were recorded just before and immediately, 5, 10 and 15 minutes after the procedure. Data were analyzed with independent t-test and ANOVA with repeated measurement.
there was no significant difference in the mean O2Sat between the two groups before the procedure, but a significant increase was observed immediately, 5, 10 and 15 minutes after the standard procedure. HR and PIP did not change significantly between the two groups.
Discussion and considering the necessity of endotracheal suctioning for cleaning the secretions, by performing it in a correct way, conducting hyper-oxygenation before suctioning for 30-60 seconds and after that for one minute, reducing its time to less than 15 seconds, and using a catheter with a diameter less than the half of endotracheal internal diameter, we can reduce the side-effects, as well as preventing hypoxia in patient.
