Objectives Current guidelines emphasize early recognition of pediatric septic shock using clinical examination findings. Elevated serum lactate has been associated with increased mortality in adult patients with septic shock. Our objective was to determine the association between the initial serum lactate obtained in the pediatric emergency department (PED) from patients treated for septic shock and the use of vasoactive medication within 24 hours. Methods This was a retrospective study from 2008 through 2012 of PED patients at a tertiary care children’s hospital. Patients younger than 18 years treated for septic shock were included if they had a serum lactate obtained in the PED. Results Eight hundred sixty-four PED encounters met inclusion criteria. Median initial PED lactate was 2.1 mmol/L (interquartile range, 1.4-3.2 mmol/L). Overall, 121 patients (14%) received vasoactive medication within 24 hours of the initial PED lactate. A multivariable logistic regression analysis demonstrated associations between initial lactate levels of 3.1 to 5 mmol/L (odds ratio, 1.82; 95% confidence interval, 1.02-3.26) and 5.1 mmol/L or greater (odds ratio, 5.00; 95% confidence interval, 2.56-9.76) and the use of vasoactive medication within 24 hours. Other factors associated with use of vasoactive medication within 24 hours included hypotension, abnormal pulses, and mental status changes. Conclusions Increased initial lactate is associated with use of vasoactive medication within 24 hours in PED patients with septic shock.
