[Application value of BIS and S100β combined with Copeptin in patients with acute severe carbon monoxide poisoning].

Objective: To explore the application value of bispectral index(BIS) , specific protein 100β(S100β) combined with Copeptinin patients with acute severe carbon monoxide poisoning (ASCMP). Methods: A total of 256 patients with acute carbon monoxide poisoning admitted to Hengshui People's Hospital from June 2018 to June 2020 were collected, and they were divided into 30 mild cases, 40 moderate cases and 186 severe cases according to the degree of poisoning. Among them, patients with severe carbon monoxide poisoning were divided into a poor prognosis group (20 cases) and a good prognosis group (166 cases) according to whether adverse events occurred. The changes of creatine kinase isoenzyme (CK-MB) , N-terminal precursor B-type brain natriuretic peptide (NT-proBNP) , BIS, S100β, and Copeptin in poisoned patients were measured. Logistic regression analysis and receiver operating characteristic (ROC) curve were used to evaluate the significance of relevant indicators for ASCMP patients. Results: Compared with the mild-to-moderate group, CK-MB, NT-proBNP, S100β, Copeptin increased, and BIS value decreased in the severe group (P< 0.05). 24 hours after admission, compared with the good prognosis group, CK-MB, NT-proBNP, S100β, Copeptin in the poor prognosis group increased, and the BIS value decreased (P<0.05). In the poor prognosis group, CK-MB, NT-proBNP, S100β, and Copeptin at 72 hours after admission were all lower than those at 24 hours after admission, and the BIS value was higher than that at 24 hours after admission (P<0.05). Logistic regression analysis showed that ASCMP patients with increased S100β, Copeptin, and decreased BIS values had an increased risk of adverse events (P<0.05). The ROC curve showed that the area under the curve of the combined detection of BIS, S100β and Copeptin was 0.859, which had a great predictive value for the prognosis of ASCMP patients. Conclusion: BIS, S100β combined with Copeptin detection is of great value for early assessment of ASCMP disease and prognosis prediction.目的： 探讨脑电双频指数（BIS）与特异性蛋白100β（S100β）联合和肽素（Copeptin）在急性重度一氧化碳中毒（ASCMP）患者中的应用价值。 方法： 收集衡水市人民医院2018年6月至2020年6月收治的急性一氧化碳中毒患者256例，根据中毒程度分为轻度30例、中度40例和重度186例。其中，重度一氧化碳中毒患者以是否发生不良事件分为预后不良组（20例）和预后良好组（166例）。测定中毒患者肌酸激酶同工酶（CK-MB）、N末端B型脑钠肽前体（NT-proBNP）、BIS、S100β、Copeptin变化，采用logistic回归分析和受试者工作特征（ROC）曲线评价相关指标对ASCMP患者的意义。 结果： 与轻中度组比较，重度组中毒患者CK-MB、NT-proBNP、S100β、Copeptin升高，BIS值降低（P<0.05）。入院后24 h，与预后良好组比较，预后不良组患者CK-MB、NT-proBNP、S100β、Copeptin升高，BIS值降低（P<0.05）；预后不良组患者入院后72 h的CK-MB、NT-proBNP、S100β、Copeptin均低于入院后24 h，BIS值高于入院后24 h（P<0.05）。logistic回归分析显示，S100β、Copeptin升高，以及BIS值降低的ASCMP患者发生不良事件的危险性增加（P<0.05）。ROC曲线显示，BIS、S100β、Copeptin联合检测曲线下面积为0.859，对ASCMP患者预后的预测价值较大。 结论： BIS与S100β联合Copeptin检测对早期评判ASCMP病情及预后预测有重要价值。.
