Caring for the radial artery post-angiogram: a pilot study on a comparison of three methods of compression

A coronary angiogram, a diagnostic tool to visualize the coronary anatomy, has traditionally been accessed through the femoral artery. However, in the last 20 years, the radial artery has gained more popularity among physicians and patients, offering an alternative to the femoral approach. Various methods of applying compression to the radial puncture site have been used, but no research has been done to demonstrate the most effective way of achieving hemostasis while limiting complications and ensuring the efficient use of nursing and medical resources.

The purpose of this pilot study was to compare two devices and three methods for achieving hemostasis after a transradial angiogram while assessing vascular complications and time endpoints.

A mechanical device (Terumo™ wristband) and a hydrophilic wound dressing (Clo-Sur P.A.D.) were used. The Terumo band was studied twice, using the current method and a fast-release method.

Taking into account the small sample size of this pilot study (N = 25 per group), statistically significant differences (p ≤ 0.005) are seen in time to discharge in the fast-release Terumo (134.0 minutes) and Clo-Sur P.A.D. groups (113.7 minutes), as compared with the control Terumo group (178.2 minutes), without increasing vascular complications.
