To investigate the accuracy of three model formulae for ultrasound quantification of pleural effusion (PE) volume in patients in supine position.
A prospective study including 100 patients with thoracentesis and drainage of PE was conducted. Three model formulae (single section model, two section model and multi-section model) were used to calculate the PE volume. The correlation and consistency analyses between calculated volumes derived from three models and actual PE volume were performed.
PE volumes calculated by three models all showed significant linear correlations with actual PE volume in supine position (all p < 0.001). The reliability of multi-section model in predicting PE volume was significantly higher than that of single section model and slightly higher than that of two section model. When compared with actual drainage volume, the intra-class correlation coefficients (ICCs) of single section model, two section model and multi-section model were 0.72, 0.97 and 0.99, respectively. Significant consistency between calculated PE volumes by using two section model and multi-section model existed for full PE volume range (ICC 0.98).
Based on the convenience and accuracy of ultrasound quantification of PE volume, two section model is recommended for pleural effusion assessment in routine clinic, though different model formulae can be selected according to clinical needs.
探讨三种超声量化平卧位胸腔积液（PE）量的模型公式的准确性。
前瞻性纳入 100 例行胸腔穿刺及引流的 PE 患者。使用三种模型公式（单截面模型、双截面模型和多截面模型）计算 PE 量。分析三种模型计算值与实际 PE 量之间的相关性和一致性。
三种模型计算的 PE 量与平卧位实际 PE 量均呈显著的线性相关（均 p<0.001）。多截面模型预测 PE 量的可靠性明显高于单截面模型，略高于双截面模型。与实际引流量相比，单截面模型、双截面模型和多截面模型的组内相关系数（ICC）分别为 0.72、0.97 和 0.99。双截面模型和多截面模型在全 PE 量范围内计算的 PE 量具有显著的一致性（ICC 0.98）。
基于超声量化 PE 量的便利性和准确性，推荐在常规临床中使用双截面模型评估胸腔积液，但可根据临床需要选择不同的模型公式。
