Summary

This study is a single-center, prospective, observational study. After successful cardiopulmonary resuscitation for patients with cardiac arrest, they will be transferred to the emergency intensive care unit for further standardized targeted temperature management. When evaluating that the patient meets the indications for lumbar puncture and there are no contraindications for lumbar puncture, lumbar puncture examinations will be completed immediately after return of spontaneous circulation (ROSC), at 24 hours of hypothermia, at 72 hours of hypothermia, and after rewarming. Routine cerebrospinal fluid examinations such as cerebrospinal fluid routine, cerebrospinal fluid biochemistry, and cerebrospinal fluid lactate will be sent for inspection. At the same time, 6 ml of cerebrospinal fluid will be retained and stored in a refrigerator at -80°C. After sample collection is completed, enzyme-linked immunosorbent assay (ELISA) will be used to detect markers such as NSE, HCH-L1, NFL, tau, MBP, GFAP, and S100β. While performing the lumbar puncture examination, peripheral blood will be collected. After centrifugation for 10 minutes (4000 revolutions), serum will be retained and stored in a refrigerator at -80°C to complete the examination of the above markers. After 3 months, the patient\'s neurological function prognosis will be followed up according to the Pittsburgh Cerebral Performance Category (CPC) scale.
