Abstract :
Background: One of the most common and important diagnostic methods for the detection of heart diseases is coronary angiography.
The aim of this study was to determine the optimum angle of the bed by using vital signals to optimize the patient’s position after the
angiography. Materials and Methods: This study was a randomized clinical trial (RCT) on participants after angiography who were
divided into five groups. The first group was placed routinely in a supine position. In the other groups, all of the patients were placed
in bed by angle 15°, 30°, 45°, and 60° upward. In each group, vital signals were measured that included blood pressure, percent of
blood oxygen saturation, heart rate, respiratory rate, and temperature. All of measured data compared with the pain score has been
achieved from numerical pain scale. The data were analyzed by descriptive statistics method, variance analysis, and post hoc tests
in the Statistical Package for the Social Sciences (SPSS) software, version 16. Estimation of the relationship was done by MATLAB
version 2011. The level of significance was considered to be 0.05. Results: In various groups, there was no significance difference
in demographic variables such as gender, age, height, and weight. The mean of pain score, heart rate, systolic blood pressure, and
respiratory rate changed significantly (P < 0.05) but the temperature variation, blood oxygen saturation, and diastolic blood pressure
in subjects were not significant (P > 0.05). It showed linear changes between pain and systolic blood pressure, respiratory rate,
and heart rate changes. A dramatic reduction was also seen in systolic blood pressure, respiratory rate, heart rate, and also pain at
an angle of 45°. Conclusion: This study showed that, 45° was the best angle of the bed to optimize the patient’s position after the
procedure, based on his/her vital signs and pain score. Thus, in order to relive pain, this change in bed angle is advised to be planned
by postangiography nurses in patients after coronary angiography.
