Radial artery catheterization in neonates, infants, and young children is a common and useful invasive procedure that brings technical placement challenges and potential complications due to the small diameter size of the radial artery in these patients.

The aim of this study is to determine appropriate catheter sizes in infants up to 6 months of age.

A total of fifty infants undergoing general anesthesia or hospitalized in the neonatal intensive care unit were included.

Images of the radial artery diameter were obtained from the infant's wrist using Philips EPIQ Diagnostic Ultrasound System CVX Release 4.0. All images obtained were distal in the forearm, medial to the border of the styloid process of the radius, at the point of maximal impulse of the radial artery, and with the wrist at a 45-degree angle position.

We recorded postmenstrual age, chronological age, gender, weight, location, comorbidities, medications, weight, and vital signs of each individual.
