Effects of endotracheal tube fixation methods on haemodynamic parameters during endotracheal suction: A single‐blind non‐randomized clinical trial study.

Aim: This study aimed to determine the effect of the methods used in endotracheal tube fixation on haemodynamic parameters (systolic and diastolic blood pressure, heart rate and oxygen saturation) during endotracheal suction. Methods: The sample of this prospective, parallel two‐armed, single‐blind non‐randomized clinical trial study included 86 intubated patients treated in the cardiovascular surgery intensive care unit between September 2016 and December 2017. The endotracheal tube was fixed with tube holders in the intervention group (n = 43), whereas the endotracheal tube was fixed with plasters in the control group (n = 43). The patients' haemodynamic parameters were measured before, during, at the end of suction, and 5 and 15 min after suction. Results: In comparison with the patients with plasters, patients with tube holders had significantly lower systolic blood pressure 15 min after endotracheal suction and significantly lower diastolic blood pressure during and at the end of endotracheal suction. Oxygen saturation of the patients with tube holder during, at the end, and following 5 min after endotracheal suction were higher than patients with plaster. Heart rate was not affected during endotracheal suction in both groups. Conclusion: The study showed the tube holder affected the haemodynamic parameters during endotracheal suction less than the plaster. Summary statement: What is already known about this topic? Endotracheal suction is one of the essential nursing care interventions with mechanically ventilated patients.Nurses are responsible for selecting and using the most secure endotracheal tube fixation.Haemodynamic parameters are affected during endotracheal suction. What this paper adds? Some haemodynamic parameters are affected during endotracheal suction in two endotracheal tube fixation methods.The endotracheal tube holder affects systolic blood pressure, diastolic blood pressure, and peripheral oxygen saturation less than plaster fixation during endotracheal suction.The heart rate and oxygen saturation were not affected in both endotracheal tube fixation methods during endotracheal suction. The implications of this paper: The endotracheal tube holder can be used safely in the cardiovascular surgery intensive care patients with unstable haemodynamic parameters.These study findings guide intensive care nurses in preventing some haemodynamic changes caused by endotracheal suction.
