A modified supine position significantly improves bladder emptying after percutaneous coronary intervention (PCI). This simple nursing intervention reduces voiding difficulties and promotes better bladder function in cardiovascular disease patients.
Area of Science:
- Cardiology
- Urology
- Nursing Care
Background:
- Percutaneous coronary intervention (PCI) is a common cardiovascular disease treatment.
- Standard post-PCI care involves supine bed rest, which can cause voiding difficulties.
- Impaired micturition post-PCI can negatively impact patient recovery and comfort.
Purpose of the Study:
- To evaluate the effectiveness of a modified supine position in facilitating bladder emptying after PCI.
- To compare bladder function outcomes between patients receiving standard care and those in a modified supine position.
- To identify potential improvements in post-procedural voiding for cardiovascular patients.
Main Methods:
- A randomized controlled trial was conducted with 300 patients undergoing PCI.
- The intervention group was positioned supine with the bed tilted 20° upright and a pillow support.
- The control group received standard supine positioning post-PCI.
Main Results:
- The intervention group showed a significantly shorter time to first void (5 vs. 15 minutes).
- Fewer patients in the intervention group required voiding assistance (8.6% vs. 35.3%).
- Residual urinary volumes were significantly lower in the modified supine position group (88.71 vs. 248.22 mL).
Conclusions:
- A modified supine position effectively reduces impaired micturition after PCI.
- This nursing intervention helps preserve normal bladder function in patients post-cardiac procedure.
- The modified position offers a simple, non-invasive method to improve patient outcomes after PCI.
