Examining brain injury markers in patients after cardiac arrest

The Relationship Between Brain Injury Biomarkers in Cerebrospinal Fluid and Blood of Patients After Cardiac Arrest and Prognosis.

Observational Capital Medical University · NCT06624488

This study is trying to see if certain brain injury markers in the fluid around the brain and in the blood can help predict how well patients will recover after cardiac arrest.

What this trial studies

This observational study investigates the relationship between brain injury biomarkers found in cerebrospinal fluid and blood of patients who have experienced cardiac arrest. Following successful cardiopulmonary resuscitation, patients will undergo lumbar puncture at various time points to collect cerebrospinal fluid samples for analysis. The study aims to evaluate the prognostic value of these biomarkers in predicting patient outcomes after cardiac arrest. The collected samples will be analyzed using enzyme-linked immunosorbent assay (ELISA) to detect specific markers associated with brain injury.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who exhibit a lack of directive movements after restoration of spontaneous circulation.

Not a fit: Patients with contraindications for lumbar puncture or those with concurrent severe brain injuries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve prognostic assessments and treatment strategies for patients recovering from cardiac arrest.

How similar studies have performed: While similar studies have explored biomarkers in brain injury, this specific approach focusing on cardiac arrest patients is relatively novel.
