This meta-analysis aimed to assess the diagnostic accuracy of lung ultrasonography in pneumonia-affected pediatric patients. Literature search of published articles in Medline, Web of Science, Scopus, Embase and Journal of Web till September 2020 were reviewed for the predescribed accuracy assessors. In compliance with the inclusion and exclusion criteria, two researchers independently screened the literature, collected the results and assessed the risks of bias using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. The pooled sensitivity and specificity, pooled positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were estimated for the meta-analysis. The overall efficiency of lung ultrasonography (LUS) was evaluated using a summary receiver operating characteristic curve. Q and I² statistics were used to determine heterogeneity. Meta disc software was used for the analysis of the study. Out of 1182 studies, only 29 articles were chosen; 25 of them were prospective studies and 4 studies were retrospective. The overall pooled sensitivity was 0.83 [95% confidence intervals (CI), 0.81–0.84] and specificity was 0.84 (95% CI, 0.81–0.86), depicting good diagnostic performance. LUS is an efficient imaging technique for detecting childhood pneumonia with a high accuracy rate. It is an appealing alternative to chest X rays to detect and follow-up pneumonia in children because it is simple to do, widely available, comparatively cheap and free of radiation hazards.

这项荟萃分析旨在评估肺部超声检查在受肺炎影响的儿科患者中的诊断准确性。为预先描述的准确性评估者审查了截至 2020 年 9 月在Medline、Web of Science、Scopus、Embase和Journal of Web上发表的文章的文献搜索。根据纳入和排除标准，两名研究人员独立筛选文献，收集结果并使用诊断准确性研究质量评估-2（QUADAS-2）工具评估偏倚风险。汇总的敏感性和特异性、汇总的阳性似然比、阴性似然比和诊断优势比被估计用于荟萃分析。肺超声检查 (LUS) 的总体效率使用汇总的受试者工作特征曲线进行评估。Q 和I ²统计量用于确定异质性。Meta disc 软件用于研究分析。在 1182 项研究中，仅选择了 29 篇文章；其中25项为前瞻性研究，4项为回顾性研究。总体汇总敏感性为 0.83 [95% 置信区间 (CI)，0.81–0.84] 和特异性为 0.84 (95% CI, 0.81–0.86)，说明诊断性能良好。LUS 是一种高效的成像技术，用于检测儿童肺炎，准确率高。它是一种有吸引力的替代胸部 X 射线检测和随访儿童肺炎的方法，因为它操作简单、可广泛使用、相对便宜且无辐射危害。
