Feasibility and safety analysis of distal radial arterial catheterization for arterial pressure monitoring in intensive care unit (ICU)
Authors' conclusion
Despite lower first-attempt success rates, DRA catheterization provides equivalent monitoring stability to CRA with significantly reduced hemostasis time and comparable safety profiles.
Study context

Secondary outcomes
Total catheterization time · similar between groups
P = 0.175
Hemostasis time · significantly shorter in DRA
P < 0.001
