Lower arterial catheter-related infection in brachial than in femoral access.

ABSTRACT

Recent guidelines do not establish a recommendation about the arterial catheter site to minimize the arterial catheter-related infection risk. In this prospective and observational study, we found a higher arterial catheter-related infection in 1085 arterial femoral sites than in 141 arterial brachial sites (5.08 vs 0 per 1000 catheter-days, respectively; odds ratio, 6.18; 95% confidence interval 1.11-infinite; P = .02). Thus, arterial brachial access should be used in preference to femoral access.
