After performing a radial artery puncture, what should be checked at the puncture site?

After performing a radial artery puncture, it is essential to check that all bleeding has stopped at the puncture site. This step is critical for ensuring patient safety and preventing complications such as excessive bleeding or the formation of a hematoma. If bleeding continues, it can lead to significant blood loss or other issues, such as infection.

While assessing the pressure and swelling, the color of the skin, and the temperature of the site are important considerations in monitoring the site after a procedure, they are secondary checks compared to ensuring that bleeding has been adequately controlled. The primary focus immediately after any venipuncture or arterial puncture should be on achieving hemostasis, which is the process that prevents and stops bleeding. Therefore, confirming that all bleeding has stopped is the most crucial step following a radial artery puncture.
