ABSTRACT
Ultrasound-guidance increases success rate and reduces complications compared to traditional palpation for radial artery catheterization. However, in special groups of patients, such as pediatric, older, obese, hypotensive population, and patients with chronic kidney disease (CKD), ultrasound-guided arterial cannulation can still be improved. The current available evidence revealed some techniques for improvement of success rate, in consideration of various modifiable factors during the procedure. In this narrative review, we summarized and illustrated techniques in four different aspects related to plane-needle relationship, ultrasound probe, patient’s artery, and insertion needle, which may provide inspiration for better practice in the future.
