Safety and Sustainability of Axillary Versus Radial Arterial Catheters in Critically Ill Children: A Retrospective Comparative Study
Authors' conclusion
In this critically ill pediatric cohort, axillary arterial catheters were used longer and in a more severely ill population than radial catheters. Despite these differences, both catheter types demonstrated comparable safety and sustainability profiles.
