The effect on back pain, anxiety, and comfort levels of an elevated supine position and back support applied to patients undergoing coronary angiography: A randomized controlled experimental study.

Objectives: To determine the effect of elevated supine position with back support on back pain, anxiety and comfort in patients undergoing coronary angiography.

Methods: This randomized-controlled, experimental study was conducted in the Coronary Intensive Care Unit between September 2021 and January 2022, with an intervention group of 51 patients and a control group of 53 patients. Data were collected using a patient information form, a visual analog scale, the anxiety state inventory and the immobilization comfort questionnaire. Following angiography, the intervention group received pillow support to the back and the bedhead was elevated to 30 degrees. Routine nursing care was applied to the control group. In both groups, the severity of back pain was measured at 0, 2, and 4 hours, and anxiety and comfort at 0 and 4 hours.

Results: The pain severity at 2 and 4 hours after the procedure was determined to be significantly lower in the intervention group than in the control group (p<0.001, p<0.001). At 4 hours, the anxiety levels were similar in both groups (p<0.05), and the comfort level was higher in the intervention group (p<0.001). The mean pain value was 6.003 points lower and the comfort level was 20.499 points higher in the intervention group than in the control group.

Conclusion: The elevated supine position with back support was seen to reduce back pain, increase comfort, and did not change anxiety levels.Clinical Trials No: NCT05546216.
