Clinical Trial Summary

Aim: The aim of this study was to examine the effect of different bed-head angles given to patients lying in the supine position in an intensive care unit on the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation. Methods: The study was conducted with 50 intensive care patients aged 18 and over in a general surgery intensive care unit in Turkey. With each patient in the supine position, the bed-head was raised to an angle of 0, 20, 30 and 45 degrees without a pillow, and the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation were recorded after 0 and 10 minutes.

Description:

Aim: The aim of this study was to examine the effect of different bed-head angles given to patients lying in the supine position in an intensive care unit on the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation. Design: This was a non-randomised quasi-experimental repeated measures study. Settings: The study was conducted with 50 intensive care patients aged 18 and over in a general surgery intensive care unit in Turkey. Methods: With each patient in the supine position, the bed-head was raised to an angle of 0, 20, 30 and 45 degrees without a pillow, and the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation were recorded after 0 and 10 minutes. The data obtained was evaluated using the Mann-Whitney test, the Kruskal Wallis test and the Bonferroni test.
