Overview
Brief Summary
Because of its high incidence, it is essential to determine the neurological prognosis after cardiac arrest. However, there is not much information to guide post-cardiac arrest care. Also, dynamic monitoring of the state of the brain can help provide information about the patient's prognosis other than previously described serum biomarkers. Therefore, the researchers will monitor postcardiac arrest patients in the intensive care unit for 48 hours by electroencephalogram and cerebral oximetry and collect blood samples for serum biomarkers: neuron-specific enolase (NSE), human neurogranin (NRGN) and human trigger receptor expressed on myeloid cells (TREM-2), which are associated with neuronal damage. And investigate the relation of these data to mortality.
Detailed Description
After cardiac resuscitation and intubation, the patient will be followed up with electroencephalogram-based monitoring and cerebral oximetry in the ICU for 48 hours. As standard, post-CPR patients will be sedated with midazolam (0.02- 0.1 mg/kg/s) and remifentanil (0.25- 0.5 mcq/kg/min) for 24 hours. Brain function measurements will be recorded under sedation for the first 24 hours and without sedation for the second 24 hours. The values recorded were suppression ratio, suppression time, patient state index, oxyhemoglobin and deoxyhemoglobin, and regional oxygen saturation. After 24 hours, a 2 ml blood sample will be taken for biomarkers (NSE, NRGN, TREM-2). Patient survival will be followed up for seven days and 28 days. The demographic data of the patients (age, gender, body mass index, ASA scores, comorbidities, history of previous operations), blood pressure, heart rate and SpO2, CPR duration, the reason for arrest(4H/4T), and inotropic-vasopressor support before and after arrest will be recorded; GCS, APACHE-2, and SOFA scores will be recorded when the patient is first admitted to the intensive care unit and at the time of cardiac arrest.
