Abstract

Objectives: To describe epinephrine dosing distribution using time-stamped data and assess the impact of dosing strategy on survival after ECPR in children.

Methods: This was a retrospective study at five pediatric hospitals of children <18 years with an in-hospital ECPR event. Mean number of epinephrine doses was calculated for each 10-minute CPR interval and compared between survivors and non-survivors. Patients were also divided by dosing strategy into a frequent epinephrine group (dosing interval of ≤5 min/dose throughout the first 30 minutes of the event), and a limited epinephrine group (dosing interval of ≤5 min/dose for the first 10 minutes then >5 min/dose for the time between 10 and 30 minutes).

Results: A total of 191 patients were included. Epinephrine was not evenly distributed throughout ECPR, with 66% of doses being given during the first half of the event. Mean number of epinephrine doses was similar between survivors and non-survivors the first 10 minutes (2.7 doses). After 10 minutes, survivors received fewer doses than non-survivors during each subsequent 10-minute interval. Adjusted survival was not different between strategy groups [OR of survival for frequent epinephrine strategy: 0.78 (95% CI 0.36-1.69), p = 0.53].

Conclusions: Survivors received fewer doses than non-survivors after the first 10 minutes of CPR and although there was no statistical difference in survival based on dosing strategy, the findings of this study question the conventional approach to EPCR analysis that assumes dosing is evenly distributed.
