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.

- 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
- 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
