AbstractAlthough there are many studies on arterial catheter-related infection (ACRI) there is little information on the relative risks associated with different catheter access sites. In previous studies we have shown a higher incidence of ACRI in femoral than in radial access sites. This prospective observational study was designed to compare the incidence of ACRI in patients on an intensive care unit with femoral versus dorsalis pedis access sites. We compared 1085 femoral arterial catheters inserted for a cumulative 6497 days with 174 dorsalis pedis catheters inserted for a cumulative 1050 days. We detected 33 cases of ACRI in the femoral access group (11 with bacteraemia and 22 with line site infection; 5.08 infections per 1000 catheter-days) but none in the dorsalis pedis access group. There were no significant differences between the two groups regarding age, sex, Acute Physiological Assessment and Chronic Health Evaluation (APACHE) II, diagnosis, previous arterial catheter insertion, use of mechanical ventilation, use of antimicrobials or catheter duration. Regression analysis showed a higher incidence of ACRI for femoral than for dorsalis pedis access sites (odds ratio: 7.6; 95% confidence interval: 1.37-infinite; P=0.01). These results suggest that dorsalis pedis arterial access should be used in preference to femoral arterial access in order to reduce the risk of ACRI.Copyright (c) 2009 The Hospital Infection Society.
