| 目的 探讨两种超声多平面测量公式用于定量坐位患者胸腔积液体积的准确性。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，均取坐位行超声检查，采用一个线性公式和两个多平面测量（柱体模型、可变柱体模型）公式计算胸腔积液体积（V预1、V预2、V预3），随后立即于超声引导下行胸腔穿刺引流，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预与V实的一致性。结果 共收集87例胸腔积液患者，其中9例进行了双侧胸腔积液引流（共96处胸腔积液）；V实为99.9～799.6 ml，平均（532.8±183.2）ml；训练组中各模型测得胸腔积液体积V预1、V预2、V预3分别为（507.6±158.2）、（515.2±170.7）、（508.3±166.9）。线性回归分析显示，V预1、V预2、V预3与V实均呈线性相关（R2=0.697、0.912、0.945）；一致性分析显示，训练组中V预1、V预2、V预3与V实的ICC分别为0.833、0.955、0.972，验证组中V预1、V预2、V预3与V实的ICC分别为0.828、0.957、0.984；Bland-Altman图分析显示，V预与V实均具有良好的一致性。结论 超声多平面测量能准确定量胸腔积液体积，可变柱体模型具有最高的准确性，柱体模型次之，均可在临床推广应用。 |

| Abstract: |
| Objective To research the accuracy of two ultrasound multiplanar measurement formulas for quantitative pleural effusion volume in patients in the seated upright position.Methods A prospective study was used to collect patients with pleural effusion treated for clinical need of drainage during the February-July, 2023 .Patients went an ultrasound examination in the seated upright position，we used a linear formula and two multiplanar measurement formula（column model，variable column model） to calculate the pleural effusion （Vforecast1、Vforecast2、Vforecast3），then immediately did chest puncture drainage with ultrasound guided，recorded the actual chest drainage as Vreal.Linear-regression analysis was taken between Vforecast and Vreal，The intra-group correlation coefficient (ICC) and Bland-Altman diagram were used to analyze the consistency between Vforecast and Vreal .Results A total of 87 patients with 96 pleural effusion were collected include 9 patients which had bilateral pleural effusion; Vreal was 99.9-799.6 ml, mean value was (532.8 ± 183.2) ml; in the training groupVforecast1、Vforecast2、Vforecast3 were (507.6 ± 158.2), (515.2 ± 170.7), and (508.3 ± 166.9).Linear regression analysis showed that Vforecast1、Vforecast2、Vforecast3 were linearly associated with Vreal (R2=0.697,0.912 and 0.945 respectively).The consistency analysis showed that the ICC of Vforecast1、Vforecast2、Vforecast3 in the training group were 0.833,0.955 and 0.972 respectively, while the ICC of Vforecast1、Vforecast2、Vforecast3 in the validation group were 0.828,0.957 and 0.984 respectively; the Bland-Altman plot analysis showed good agreement between Vforecast and Vreal.Conclusion Ultrasound multiplanar measurements can accurately quantify the pleural effusion volume, and the variable column model has the highest accuracy, followed by the column model，both can be used in clinical practice. |
