【 摘 要 】

Background & Objective: The use of two dimensional ultrasound technique allows radial artery cannulation to take place under real time visualization and may increase the success rate of first time pass of the needle and reduce the complications of the invasive procedure compared to traditional palpation and trial method. We aimed to compare the success rate of radial arterial catheter insertion at first attempt and average time for successful first attempt by traditional palpation method with ultrasound guided technique in adult patients undergoing open heart surgery.
