Novel Local Infiltration Anesthesia for Radial Artery Cannulation.

Plain-language summary

This clinical trial aims to compare the pain scores and cannulation success rates of conventional, bar-shaped, and V-shaped local infiltration anesthesia in participants' radial artery cannulation. The main questions it aims to answer are: * Are bar-shaped and V-shaped more successful than the conventional block in radial artery cannulation? * Are bar-shaped and V-shaped less painful than the conventional block in radial artery cannulation? Participants will describe their pain score during their radial artery cannulation. Researchers will compare the pain scores and cannulation success rates in bar-shaped, V-shaped, and conventional line blocking to see if bar-shaped and V-shaped blocking is better choices than conventional line blocking.
