This study assessed the effect of bevel direction on the success rate of ultrasound guided radial artery catheterization. Methods: A total of 204 patients requiring radial artery catheterization were randomly divided into bevel-up (n = 102) and bevel-down (n = 102) groups. Success rate, cannulation time, and number of attempts were compared groups. |
