What is the standard approach to achieving hemostasis after radial artery access?

• A. Use manual pressure indefinitely until bleeding stops
• B. Leave the sheath in place and call it a day
• C. Use systemic anticoagulation to keep blood thin
• D. Achieve hemostasis with a radial compression device, monitor perfusion, and ensure adequate time and pressure to prevent hematoma

Answer: (D)

After radial artery access, the standard approach is to use a radial compression device to achieve hemostasis with a carefully controlled pressure profile, while actively monitoring hand perfusion. This method supports “patent hemostasis,” where enough pressure is applied to stop bleeding but enough flow remains through the artery to prevent thrombosis and radial artery occlusion. The device allows gradual decompression and staged reduction of pressure, which helps minimize hematoma formation and allows earlier mobilization. Monitoring perfusion—checking the radial pulse, skin color, capillary refill, and signs of ischemia—ensures the hand stays well perfused during and after closure. Other approaches, like manual pressure indefinitely, are impractical and risk tissue injury; leaving the sheath in place is unsafe; and relying on systemic anticoagulation alone does not achieve reliable local hemostasis and can increase bleeding risk.
