Episode 29: AHA Pediatric Post Cardiac Arrest Scientific Statement with Alexis Topjian

Cardiac Arrest, Critical Care, Emergency Medicine, Pediatric Emergency Medicine

On this episode, host Jason Woods talks with Alexis Topjian about the 2019 “AHA Pediatric Post–Cardiac Arrest Care Scientific Statement.” Dr. Topjian is the first author on the statement, which is the first pediatric post arrest care statement from the AHA (previously children had primarily been discussed as a special population within a primarily adult guideline). The document itself is long, but contains a large amount of useful information for bedside providers, health care administrators, and researchers.

Episode 24: Metabolic Resuscitation for Pediatric Septic Shock

Critical Care, Emergency Medicine, Sepsis

On this episode, host Jason Woods speaks with Dr Nelson Sanchez-Pinto, pediatric intensivist, about an article he co-authored that was just e-published in the last week! The article concerns a retrospective analysis of the use of HAT therapy (hydrocortisone, ascorbic acid, thiamine) at a single center PICU for the treatment of pediatric septic shock. The e-pub link is below and this post will update when it is published in print. This topic has caused significant controversy and strong emotions for the last several years, and I expect that to continue. Please take a look at the additional resources below, as well as Dr. Sanchez-Pinto’s twitter feed (@nelsonspinto), for even more information.

The highlights:

  • Study details
    • Single center, retrospective, propensity score matched
    • 557 septic shock patients in the PICU
    • 43 received HAT, 181 hydrocortisone alone, 333 neither
    • HAT patients matched 1:1 with the other groups
  • Results
    • HAT patients had lower mortality at 30-days (9 vs 28%, P=0.03) and 90-days (14 vs 37%, P=0.01) compared to no HAT or hydrocortisone
    • Similar results comparing mortality in HAT to those with hydrocortisone alone – 30-day (9 vs 30%, p=0.01) and 90 day (14 vs 37%, p=0.01)
    • No difference at 30 days in vasoactive free days or hospital free days
