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 nonrandomized 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.
