ObjectiveThe aim of the study was to describe patterns of initiation (and factors associated with delayed initiation) of vasoactive agents among pediatric emergency patients with septic shock.MethodsPatients with septic shock from November 2013 to September 2016 who had a vasoactive agent initiated for documented hypotension were classified as "guideline adherent" (hypotensive following the final fluid bolus and had vasoactive agents initiated within 60 minutes) or "delayed initiation" (hypotensive after the final bolus and were initiated on vasoactive agents after >60 minutes). Patient-level factors (demographics, presence of underlying condition including central venous catheter, and markers of disease severity) and outcomes (mortality, length of stay) were compared between groups.ResultsOf the 37 eligible patients, 17 received vasoactive agents within "guideline adherent" timelines and 10 were "delayed initiation." An additional group was identified as "transient responders"; these patients were normotensive after a final fluid bolus but developed hypotension and were initiated on a vasoactive agent within 2 hours after admission (n = 10). We found no significant difference between the "guideline adherent" and "delayed initiation" groups according to patient-level factors or outcomes; "transient responders" were more likely than other groups to have a central venous catheter and had longer lengths of stay.ConclusionsAlthough there are perceived barriers to vasoactive agent initiation, we found no significant difference in patient-level factors between the timely and delayed groups. This study also identified a group of patients labeled as transient responders, who initially appeared volume responsive but who required vasoactive support within several hours. This cohort requires further study.Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
