When radial cannulation is not feasible, alternative sites like the axillary artery may be utilized. However, the safety and sustainability of axillary arterial catheters compared to radial catheters in this population remain unclear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>This study aims to assess the safety and sustainability of axillary arterial catheters compared to radial arterial catheters in pediatric intensive care unit patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective, case\u2013control study at a university\u2010affiliated tertiary care pediatric intensive care unit. Patients aged 18\u2009years or younger with axillary arterial catheters from January 2007 to December 2023 were compared to patients of similar ages with radial catheters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A computerized chart review identified 306 patients with axillary catheters, compared to 306 randomly selected patients with radial catheters. The rate of catheter site replacement was identical in both groups (40 out of 306). The median duration of axillary catheter use was 34\u2009h longer (95% CI: 24\u201348; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Only one patient in the axillary group (0.33%) experienced a vascular complication, recovering fully after intervention. Patients with axillary catheters were characterized by a higher Pediatric Index of Mortality 3 scores, Vasoactive\u2010Inotropic Scores, and PICU mortality rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In this critically ill pediatric cohort, axillary arterial catheters were used longer and in a more severely ill population than radial catheters.
