Elevated serum neurologic biomarker profiles after cardiac arrest in a porcine model.

ABSTRACT:

Introduction

Swine exhibit cerebral cortex mitochondrial dysfunction and neuropathologic injury after hypoxic cardiac arrest treated with hemodynamic-directed CPR (HD-CPR) despite normal Cerebral Performance Category scores. We analyzed the temporal evolution of plasma protein biomarkers of brain injury and inflammatory cytokines, as well as cerebral cortical mitochondrial injury and neuropathology for five days following pediatric asphyxia-associated cardiac arrest treated with HD-CPR.

Methods

One-month-old swine underwent asphyxia associated cardiac arrest, 10-20 min of HD-CPR (goal SBP 90 mmHg, coronary perfusion pressure 20 mmHg), and randomization to post-ROSC survival duration (24, 48, 72, 96, 120 h; n = 3 per group) with standardized post-resuscitation care. Plasma ne
