摘　　要：目的探究肺超声定量评分(LUS)对于预测重症肺炎患者病情的价值。方法选取2020年1月—2021年1月沈阳市第四人民医院重症医学科收治的86例重症肺炎患者作为研究对象。根据急性生理与慢性健康评分(APACHEⅡ),将研究对象分为非危重组、危重症组、极危组,比较不同组别研究对象LUS、氧合指数(OI)、肺泡-动脉氧分压差(A-aDO_(2))水平。随访3个月,根据研究对象预后情况将其分为存活组及死亡组,分析不同预后结局研究对象LUS、OI、A-aDO_(2)水平差异,并使用受试者工作特征曲线(ROC)分析LUS、OI、A-aDO_(2)水平对重症肺炎患者预后的预测效能。结果非危重组、危重症组、极危组患者LUS、A-aDO_(2)水平依次上升,而OI水平依次下降(P<0.05);存活组患者LUS、A-aDO_(2)水平均低于死亡组,OI水平高于死亡组(P<0.05);ROC曲线显示,LUS、OI、A-aDO_(2)水平对重症肺炎患者预后的预测效能依次降低(曲线下面积分别为0.826、0.683、0.675,均P<0.05)。结论LUS、OI、A-aDO_(2)均与重症肺炎患者病情严重程度存在一定相关性,且将以上指标用于预测重症肺炎患者预后有一定指导价值。Objective This paper aims to investigate the value of quantitative lung ultrasound score(LUS)in predicting the severity of patients with severe pneumonia.Methods Eighty-six patients with severe pneumonia admitted to the Department of Critical Care Medicine of the Fourth People's Hospital of Shenyang from January 2020 to January 2021 were selected as the study participants.According to the Acute Physiology and Chronic Health EvaluationⅡ(APACHEⅡ),they were allocated into the non-risk group,critical group,and very critical group,The LUS,oxygenation index(OI),and alveolararterial partial pressure of oxygen difference(A-aDO_(2))levels were compared between the different groups.The patients were followed up for 3 months,and allocated into the survival/death group following the prognosis of the study participants.The differences in LUS,OI,and A-aDO_(2) levels in the participants with different prognostic outcomes were analyzed.The predictive efficacy of LUS,OI,and A-aDO_(2) levels for the prognosis of patients with severe pneumonia was analyzed using receiver operating characteristic(ROC).Results The levels of LUS and A-aDO_(2) increased in turn,while the levels of OI decreased in turn in the non-risk,Critical,and very critical groups,with statistical significance(P<0.05).The levels of LUS and A-aDO_(2) in the survival group were significantly lower than those in the death group,and the levels of OI were significantly higher than those in the death group(P<0.05).ROC curves showed that the predictive efficacy of LUS,OI,and A-aDO_(2) levels for the prognosis of patients with severe pneumonia significantly decreased in turn(areas under the curves were 0.826,0.683,and 0.675,respectively,all P<0.05).Conclusion LUS,OI,and A-aDO_(2) have a certain correlation with the severity of patients with severe pneumonia,and the above indicators have a certain guiding value for predicting the prognosis of these patients.
