Abstract: 

Introduction: Eendotracheal tube suctioning is one of the most nursing cares to improve oxygenation in patients with endotracheal tube. There is controversy over the amount of negative pressure during the endotracheal tube suctioning. This study aimed to evaluate the effects of endotracheal tube suctioning with negative pressure of 100 and 200 mmHg on physiologic indices in patients hospitalized in the intensive care units.
Method: In this clinical trial, 60 patients were selected among those undergone mechanical ventilation in ICU of Isfahan’s Al-Zahra Hospital using convenience sampling method. Then the subjects randomly allocated to two groups (suctioning with negative pressure of 100 and 200 mmHg). Arterial blood oxygen saturation (SpO2), Heart rate (HR) and mean blood pressure (MBP) was measured in stages immediately before, during, 5 and 20 minutes after each type of suctioning. Data were analyzed using repeated measures ANOVA, chi-square and independent t-test.
Results: The finding of this research showed that SpO2 significantly decreased and HR and MBP significantly increased after suctioning in both groups. (P<0.05). However, these changes were not significant between the two groups (P>0.05). Conclusion: Both endotracheal tube suctioning with negative pressure of 100 and 200 mmHg are similarly effective on SpO2, HR and MBP. Therefore, nurses can perform the endotracheal tube suctioning with each of these methods. Since both methods are effective on physiological indices of patients, nurses should measure these indices before and after the endotracheal tub suctioning.
