Ultrasound-Guided Artery Cannulation Technique Versus Palpation Technique in Adult Patients in Pre-Anesthesia Room: A Randomized Controlled Trial

Background The ultrasonography-guided technique is superior to the traditional palpation technique for artery cannulation. However, considering the complexity of assembling the ultrasonography machine, this technique has not been extensively used. Here, we compared the ultrasonography-guided technique with the traditional palpation technique in adult patients in the pre-anesthesia room.
