Controlled trial of backrest elevation after coronary angiography

Area of Science:

• Cardiology
• Nursing Research
• Patient Care

Background:

• Current protocols mandate flat head of bed positioning for 5.5 hours post-coronary angiography.
• This prolonged flat positioning may impact patient comfort and recovery.

Purpose of the Study:

• To evaluate the impact of head of bed elevation on patient comfort after diagnostic coronary angiography.
• To assess the incidence and timing of post-procedural complications with elevated head of bed positioning.

Main Methods:

• 120 adult patients undergoing elective diagnostic coronary angiography were randomized into two groups.
• The experimental group experienced gradual head of bed elevation (15-60 degrees) over 5.5 hours, while the control group remained at <=15 degrees.
• Outcomes included dizziness, hypotension, bleeding, hematoma, diminished pulses, and pain levels (0-10 scale).

Main Results:

• No significant differences in complication rates (dizziness, hypotension, bleeding, hematoma, pulse changes) were observed between groups.
• The experimental group reported significantly less back pain (<=3 on a 0-10 scale) compared to the control group.

Conclusions:

• Gradual head of bed elevation after coronary angiography enhances patient comfort, specifically reducing back pain.
• This intervention does not elevate the risk of common post-procedural complications.
• Further studies are recommended to validate these findings.
