Comparison of Hemostasis Times with a Chitosan-Based Hemostatic Pad (Clo-Sur Radial™) vs Mechanical Compression (TR Band®) Following Transradial Access: A pilot Study.

Background: Hemostasis following transradial arterial access (TRA) is usually achieved by mechanical compression. This study investigated if use of a chitosan-based hemostatic pad (Clo-Sur Radial™) combined with mechanical compression (TR Band®) could shorten hemostasis time after TRA, compared with a TR Band® alone.

Methods: 40 patients undergoing cardiac catheterization and/or percutaneous coronary intervention were assigned into 4 cohorts post TRA: 10 patients received mechanical compression with a TR Band® alone for 120 min. The other 30 patients received compression with a Clo-Sur Radial™ pad combined with a TR Band® for 60 min, 45 min, and 30 min, respectively (n = 10/per cohort). Times to hemostasis and access-site complications were recorded.

Results: There were no differences in patient characteristics, mean dose of heparin, or mean activated clotting time value at the end of procedure among the four cohorts. Median time to hemostasis with the TR Band® alone was 120.5 min versus 60 min, 45 min and 30 min for the 60-min, 45-min, and 30-min Clo-Sur Radial™ pad combined with the TR Band® cohorts, respectively. No radial artery occlusion, late rebleeding nor hematoma was noted in this series of patients.

Conclusions: In this pilot trial, use of a Clo-Sur Radial™ pad in combination with a TR band® significantly shortened hemostasis time, as compared to a TR band® alone, with no increased complications noted.
