Comparison of Vasopressin to Epinephrine during Pediatric In-Hospital Cardiac Arrest

Strategic Insights

— 1 min read

Fresh data from a recent study suggest that vasopressin and epinephrine may have comparable effects on time to return of spontaneous circulation (ROSC) during pediatric in-hospital cardiac arrest (IHCA). Researchers at the Children's Hospital of Philadelphia analyzed a retrospective cohort of 41 matched pairs of patients who received vasopressin or epinephrine during IHCA.

Key Takeaways:

  • The study compared time to ROSC and diastolic blood pressure (DBP) increase in vasopressin and epinephrine patients during pediatric IHCA.
  • Vasopressor response was defined as a 5 mmHg increase in DBP, and analysis found that vasopressin responders had a subset of responders who required further research on intra-arrest DBP response.
  • The study found no significant differences in time to ROSC or DBP increase between vasopressin and epinephrine administered late during CPR.
  • The study concludes that a subset of vasopressin responders suggests further research on intra-arrest DBP response to vasopressin is needed.

Statistics:

  • 41 matched pairs of patients analyzed
  • Median CPR duration was 36.5 minutes
  • Median time to dose was 14.5 minutes
  • ROSC occurred in 10/41 (24%) vasopressin patients
  • ROSC occurred in 15/41 (36%) epinephrine patients
  • Vasopressor response occurred in 4/12 (33%) vasopressin patients
  • Vasopressor response occurred in 1/7 (14%) epinephrine patients
  • Change in DBP after vasopressin was +2.3 mmHg
  • Change in DBP after epinephrine was -5.67 mmHg
