[Advances in biomarkers for delayed encephalopathy after acute carbon monoxide poisoning]

Acute carbon monoxide poisoning (ACMP) is a common harmful gas poisoning. Underwent systematic treatment and a 2-3 week pseudo-healing period, some ACMP patients may still develop delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). DEACMP is the most severe complication that could happen to ACMP patients and comes with an exceeding high disability rate. Early identification and adequate intervention measures of DEACMP are particularly crucial for preventing its occurrence in clinical practice. At present, multiple studies have found that after ACMP occurred, a series of biomarkers showed predictive value for detecting the occurrence and development of DEACMP. This paper reviews these biomarkers and their predictive effects on DEACMP, aiming to provide theoretical guidance for the prevention and intervention of DEACMP.
