Effect of Radial Artery Compression with a Novel Automatic Pressure-Controlled Radial Compression Device: A Short-Term Prospective Interventional Pilot Study

Abstract

This study was conducted to design a novel radial compression device with the function of automatic pressure control and evaluate the feasibility and safety of this new technique. Patients who underwent transradial access (TRA) coronary angiography and percutaneous coronary intervention (PCI) in the First Hospital of Jiaxing between August 2021and October 2021 were prospectively enrolled in this pilot interventional study. The patients were grouped in a 1 : 1 ratio to receive compression with a novel device (the experimental group) or a conventional device without pressure control (the control group). The primary endpoint was the compression time, and the main secondary endpoints were rebleeding, upper-limb swelling, radial artery occlusion (RAO), and device-related pressure injury (DPI). Eighty-four patients were enrolled in this study. No significant differences were found in the baseline clinical characteristics between the two groups. Compared with the control group, the compression time in the experimental group was significantly reduced (207.4 ± 15.5 vs. 378.1 ± 19 min, $p$  < 0.001). Besides, the rate of upper-limb swelling was also significantly lower in the novel device group (2.4% vs. 85.7%, $p$  < 0.001), as well as the rate of DPI (19.05% vs. 100%, $p$  = 0.005). Furthermore, the pain score in the experimental group was significantly lower than in the control group (0.79 ± 0.42 vs. 1.83 ± 0.58, $p$  < 0.001). There were no significant differences in the rate of rebleeding (7.1% vs. 14.3, $p$  = 0.48) between the two groups. In addition, no RAO occurred in any of the groups. The novel automatic pressure-controlled radial compression device could reduce the hemostasis time and decrease the rate of adverse complications. It might be a promising and effective compression device in TRA coronary invasive procedures.
