The First national survey on Practices of Neurological Prognostication after Cardiac Arrest in China, still a lot to do.

AIMS To investigate current awareness and practices of neurological prognostication in comatose cardiac arrest (CA) patients. METHODS An anonymous questionnaire was distributed to 1600 emergency physicians in 75 hospitals which were selected randomly from China between January and July 2018. RESULTS 92.1% respondents fulfilled the survey. The predictive value of brain stem reflex, motor response and myoclonus was confirmed by 63.5%, 44.6% and 31.7% respondents respectively. Only 30.7% knew that GWR value <1.1 indicated poor prognosis and only 8.1% know the most commonly used SSEP N20. Status epilepticus, burst suppression, suppression was considered to predict poor outcome by only 35.0%, 27.4%, 20.9% respondents respectively. 46.7% knew NSE, and only 24.7% knew S-100. Only a few respondents knew that neurological prognostication should be performed later than 72h from CA either in TTM or non-TTM patients. In practice, the most commonly used method was clinical examination (85.4%). 67.9% had used brain CT for prognosis, and 18.4% for MRI. NSE (39.6%) was a little more widely used than S-100β (18.0%). However, SSEP (4.4%) and EEG (11.4%) were occasionally performed. CONCLUSIONS Neurological prognostication in CA survivors had not been well understood and performed by emergency physicians in China. They were more likely to use clinical examination rather than objective tools, especially SSEP and EEG, which also illustrated that multimodal approach was not well performed in practice.
