摘要
目的 探讨2个超声多平面测量公式用于定量坐位患者胸腔积液的准确性.方法 前瞻性收集我院2023年2～7月因临床需要行穿刺引流的胸腔积液患者87例(共引流96处胸腔积液),分为训练组56例,验证组31例.均取坐位进行超声检查,采用1个线性模型和2个超声多平面测量公式(柱体模型、可变柱体模型)分别计算胸腔积液量(V预1、V预2、V预3),随后立即于超声引导下行胸腔穿刺术,记录实际胸腔积液量(V实).采用线性回归分析V预1、V预2、V预3与V实的关系;采用组内相关系数(ICC)和Bland-Altman图分析V预1、V预2、V预3与V实的一致性.结果 训练组中V预1、V预2、V预3分别为(507.6±158.2)ml、(515.2±170.7)ml、(508.3±166.9)ml;验证组中V预1、V预2、V预3、V实分别为(551.0±172.7)ml、(568.1±198.4)ml、(563.2±200.6)ml、(563.2±208.6)ml.线性回归分析显示,训练组中V预1、V预2、V预3与V实均呈线性相关(R2 分别为0.697、0.912、0.945,均P<0.05).训练组和验证组中V预1、V预2、V预3 与V实的一致性均好(ICC分别为0.833、0.955、0.972和0.828、0.957、0.984,均P<0.05);Bland-Altman图分析显示,验证组中V预2、V预3与V实均具有良好的一致性.结论 通过超声多平面测量能准确定量坐位患者胸腔积液,其中可变柱体模型的准确率最高,柱体模型次之.
Abstract
Objective To investigate the accuracy of two ultrasound multiplanar measurement formulas for quantifying pleural effusion volume in patients in the seated upright position.Methods A prospective study was conducted,collecting data from 87 patients with pleural effusion who underwent thoracentesis drainage due to clinical indications between the February and July 2023 in our hospital,with a total of 96 sites of pleural effusion drainage.These patients were divided into a training group(n=56)and a validation group(n=31).All patients underwent ultrasonography in the seated upright position.One linear model and two ultrasound multiplanar measurement formulas(cylindrical model,variable cylindrical model)were used to calculate the volume of pleural effusion(Vforecast1,Vforecast2,Vforecast3).Subsequently,thoracentesis drainage was immediately performed under ultrasound guidance,and the actual volume of pleural effusion(Vreal)was recorded.Linear regression analysis was used to analyze the relationship between Vforecast1,Vforecast2,Vforecast3 and Vreal.Intra-class correlation coefficient(ICC)and Bland-Altman diagram were used to analyze the consistency between Vforecast1,Vforecast2,Vforecast3 and Vreal.Results In the training group,the Vforecast1,Vforecast2,Vforecast3 were(507.6±158.2)ml,(515.2±170.7)ml and(508.3±166.9)ml,respectively.In the validation group,the Vforecast1,Vforecast2,Vforecast3 were(551.0±172.7)ml,(568.1±198.4)ml and(563.2±208.6)ml,respectively.Linear regression analysis showed that Vforecast1,Vforecast2,Vforecast3 were linearly correlated with Vreal(R2=0.697,0.912,0.945,all P<0.05).There was good consistency between Vforecast1,Vforecast2,Vforecast3 and Vreal in both the training and validation groups(ICC=0.833,0.955,0.972,0.828,0.957,0.984,all P<0.05).Bland-Altman diagram analysis showed good consistency between Vforecast2,Vforecast3 and Vreal in the validation group.Conclusion Ultrasound multiplanar measurements can accurately quantify pleural effusion volume in patients in the seated upright position,with the variable cylindrical model demonstrating the highest accuracy,followed by the cylindrical model.
