摘要 目的分析急诊精神障碍患者的血氨及其他实验室指标,探讨血氨在急诊精神障碍疾病鉴别诊断中的价值。方法收集179例精神障碍患者[肝性脑病74例,非肝性脑病105例(酒精性精神障碍32例,颅内感染性精神障碍30例、精神性精神障碍25例、其他18例)]血清、全血、血浆及动脉血,检测血氨、肝功能指标[丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、γ-谷氨酰基转移酶(GGT)、碱性磷酸酶(ALP)、总胆红素(TBil)、直接胆红素(DBil)、总蛋白(TP)、白蛋白(Alb)]、肾功能指标[尿素(Urea)、肌酐(Cr)]、电解质[钠(Na+)、钾(K+)、氯(Cl-)]、血常规[红细胞计数(RBC)、白细胞计数(WBC)、血红蛋白(Hb)、血小板计数(PLT)]、凝血指标[凝血酶原时间(PT)、凝血酶时间(TT)、纤维蛋白原(FIB)]及血气指标[(pH值、二氧化碳分压(PCO2)、氧分压(PO2)]。结果肝性脑病精神障碍组TBil、DBil、ALP、Urea、Cr、K+、PT、pH值高于非肝性脑病精神障碍组(P<0.05、P<0.001);Alb、Na+、RBC、WBC、PLT、FIB、PCO2低于非肝性脑病精神障碍组(P<0.01、P<0.001)。肝性脑病精神障碍组血氨水平为64.80(44.80~101.90)μmol/L,高于非肝性脑病精神障碍组[24.50(15.25~32.30)μmol/L](P<0.001)。血氨诊断肝性脑病的ROC曲线下面积为0.895(P<0.001),以血氨50μmol/L为诊断肝性脑病的界值,其敏感度为67.6%、特异度为96.2%、阳性预测值为0.929、阴性预测值为0.821。结论血氨是急诊精神障碍患者早期鉴别诊断的敏感特异指标。
