NEUROprotection Via optimizINg Cerebral Blood Flow afTer cArdiaC arresT (NEURO-INTACT) Study

Summary

This single-center proof of concept study aims to assess the efficacy of a blood pressure strategy targeting person- and time-specific cerebral blood flow compared with standard-of-care using neuron-specific enolase as a quantitative biomarker of brain injury. Our central hypothesis is that an individualized blood pressure strategy targeting cerebral perfusion will reduce the extent of brain injury as indicated by changes in levels of neuron-specific enolase from baseline at 72 hours. To test this hypothesis, we will recruit 49 patients to an individualized blood pressure management strategy targeting cerebral blood flow, where optimal blood pressure will be serially calculated by the ICM+ brain monitoring software (Cambridge, UK) using inputs from transcranial Doppler ultrasound and near-infrared spectroscopy.
