Abstract

Background: Endotracheal suctioning is a common procedure used to mechanically remove pulmonary secretions from patients on artificial airways. Suctioning can be done with an open or closed suction system. Paradoxical conclusions have been drawn in the literature about the superiority of these methods. The aim of this study was to determine the effect of closed suctioning on haemodynamic parameters in intensive care mechanically ventilated patients.
Methods: This prospective observational study was conducted on intensive care patients who were mechanically ventilated at a university hospital between July and November 2022. Closed suctioning was performed on patients, and haemodynamic parameters and pain were registered before and after the suctioning by a research nurse.
Results: Sixty-seven patients were included (38 males and 29 females; total mean age 67.64 ± 16.16 years) in the study. Mean systolic blood pressure, respiratory rate, and oxygen saturation were higher one minute and 30 minutes after suctioning than before. Similarly, mean pulse rate and pain were higher at one, five, and 30 minutes after suctioning than before suctioning.
Conclusion: As a result, the closed suctioning technique caused significant changes in intensive care patients at both haemodynamic parameters and perceptual levels. Although this technique temporarily increases vital signs such as blood pressure and pulse in patients receiving mechanical ventilation, these increases remain within clinically safe limits. In addition, it has been determined that closed aspiration has a positive effect on oxygen saturation levels, indicating that this method plays a supportive role in oxygenation of patients.
