    ObjectiveTo assess whether the initiation of vasopressor infusions via peripheral venous catheters (PVC) compared to central venous catheters (CVC) in ED patients with early septic shock was associated with differences in processes of care and outcomes.MethodsWe conducted a post-hoc analysis of the ARISE trial. We compared participants who had a vasopressor infusion first commenced via a PVC versus a CVC. The primary outcome was 90 day mortality.ResultsWe studied 937 participants. Of these, 389 (42%) had early vasopressor infusion commenced via a PVC and 548 (58%) via a CVC. Trial participants who received a vasopressor infusion via a PVC were more severely ill, with higher median (interquartile range [IQR]) Acute Physiology And Chronic Health Evaluation (APACHE II) scores (17 [13-23] versus 16 [12-21], P = 0.003), and higher median (IQR) lactate (mmol/L) (3.6 [1.9-5.8] versus 2.5 [1.5-4.5], P < 0.001). After adjusting for baseline covariates, the estimated odds ratio for mortality for PVC-treated patients was 1.26 (95% confidence interval 0.95-1.67, P = 0.11). Trial participants who had vasopressors commenced via PVC had a shorter median (IQR) time to commencement of antimicrobials (55 [32-96] versus 71.5 [39-119] min, P < 0.001) and a shorter median (IQR) time to commencement of vasopressors (2.4 [1.3-3.9] versus 4.9 [3.5-6.6] h, P < 0.001).ConclusionThe practice of commencing a vasopressor infusion via a PVC was common in the ARISE trial and more frequent in trial participants with higher severity of illness. Commencement of a vasopressor infusion via a PVC was associated with some improvements in processes of care and, after adjustment, was not associated with an increased risk of death.© 2019 Australasian College for Emergency Medicine.
