Role of trans-radial band protocols in radial artery occlusion: Randomized trial
Cardiology; School of Nursing and Midwifery, Pakistan
Background: Radial artery occlusion is a common complication of coronary angiography via radial artery, attributed to the prolonged use of trans-radial band post procedure. Literature suggests there is no standard protocol for radial band deflation, and it varies across institutions. However, the protocol suggested by Cohen and Alfonso is widely used globally. This study aims to test whether our hospital's radial band deflation protocol is non-inferior to the protocol of Cohen and Alfonso, which affirms lesser complications.
Methods: This is an outcome assessor blinded, non-inferiority trial conducted at a tertiary care hospital in Karachi. We enrolled 100 patients who underwent coronary angiography from radial access and gave written informed consent. The intervention group received protocol A, that is in practice at the institution, while the control group received protocol B, developed by Cohen and Alfonso. The primary outcome was occurrence of radial artery occlusion at 24 h. The secondary outcomes included hematoma and bleeding after radial band removal.
Results: The mean age of the participants in the trial was 58.3 ± 11.5 years, while 63% of them were men. Participants in both the groups had similar baseline characteristics. Radial artery occlusion was not significantly different between protocol A and protocol B (10% vs. 14%, p = 0.49, respectively). Similarly, hematoma and bleeding after trans-radial band removal showed no statistical difference between the groups.
Conclusion: Trans-radial band deflation practice at our institution was non-inferior to Cohen and Alfonso's protocol in the incidence of radial artery occlusion after coronary angiography.
