摘要
目的 探讨早期乳酸测定联合儿童危重病例评分(PCIS)在儿童重症监护室(PICU)脓毒症患儿预后评估中的作用。方法 回顾性分析2016年6月至2018年6月广东医科大学附属医院PICU 516例脓毒症患儿的临床资料,根据入院后28 d结局将患儿分为存活组和死亡组。记录2组患儿入PICU后24 h内PCIS评分相关生理学参数并评分;绘制受试者工作特征曲线(ROC曲线),采用ROC曲线下面积(AUC)评价早期乳酸测定联合PCIS评分在PICU脓毒症患儿预后评估中的作用。结果 516例脓毒症患儿中,普通脓毒症患儿238例(46.1%),严重脓毒症患儿262例(50.8%),脓毒性休克患儿16例(3.1%);存活组488例(占94.6%),死亡组28例(占5.4%)。死亡组乳酸值[2.8(1.1,10.3) mmol/L]明显高于存活组[1.2(0.8,1.9) mmol/L],PCIS评分[86(82,88)分]明显低于存活组[92(86,96)分],差异均有统计学意义(Z=9 953.5、3 259.5,均P<0.05)。ROC曲线分析显示,乳酸值、PCIS评分及乳酸值联合PCIS评分评估PICU脓毒症患儿预后的AUC分别为0.728、0.761、0.829(Z=3.744、6.127、7.759,均P<0.05)。早期乳酸测定联合PCIS评分与早期乳酸监测值、PCIS评分间AUC比较,差异有统计学意义(Z=2.114、2.122,均P<0.05);早期乳酸监测值与PCIS间AUC比较,差异无统计学意义(Z=0.480,P>0.05)。结论 早期乳酸监测及PCIS评分均能预测PICU脓毒症患儿的预后,但二者联合效果更佳。
