Patient comfort and access site outcomes with a screw-based mechanical radial compression device following transradial coronary intervention: A quasi-randomized study

Objective: To evaluate whether a screw-based mechanical radial compression device improves hemostasis success, patient-reported pain and satisfaction compared with conventional manual compression after transradial coronary intervention.Methods: A prospective, quasi-randomized trial was conducted in 248 patients undergoing percutaneous coronary intervention (PCI).Participants were allocated to either mechanical (n = 124) or manual groups (n = 124) in an 1:1 ratio.The primary outcome was successful hemostasis at 6 hours after compression.Bleeding and hematoma were assessed within 24 hours after the procedure.Pain intensity, discomfort, and overall satisfaction, were also recorded.Betweengroup comparisons were summarized using risk ratios with 95% confidence intervals.Results: Successful hemostasis at 6 hours was significantly higher in the mechanical group compared with the manual group (89.5% vs. 83.9%;p = 0.016).The mechanical group had lower access-site bleeding (5.7% vs. 14.5%, p = 0.02) and fewer hematomas (4.8% vs. 12.1%, p = 0.04).Pain scores were significantly lower with the screw-based device both before (2.0 (1.8) vs. 2.7 (2.2), p = 0.009) and 30 minutes after band removal (1.2 (1.3) vs. 1.9 (2.0), p = 0.005).Patients also reported less discomfort (25.0% vs. 37.1%; p = 0.040) and higher satisfaction (84.7% vs. 67.7%;p = 0.002) in mechanical group.The were no complications related to a screw-based device use.Conclusions: Compared with manual compression, a screw-based device provides superior hemostatic efficacy and reduces access-site complications while significantly improving patient experience, with lower pain during compression and after band removal.
