高频肺部超声与X线在新生儿肺炎诊断中的价值比较

Comparison of the value of high-frequency pulmonary ultrasound and X-ray in the diagnosis of neonatal pneumonia

目的比较高频肺部超声与X线在新生儿肺炎诊断中的应用价值。方法选取2021年1月至12月江西省宜春市人民医院收治的90例疑似肺炎的新生儿作为研究对象,对入选患儿分别进行高频肺部超声及X线检查,以临床病理学结果为金标准,计算并比较两种检查方式的诊断效能。结果临床病理学结果显示阳性84例,阴性6例;高频肺部超声检查结果显示阳性81例,阴性4例,其灵敏度、特异度、准确率及阳性和阴性预测值分别为96.43%、66.67%、94.44%、97.59%、57.14%;X线检查结果显示阳性75例,阴性2例,其灵敏度、特异度、准确率及阳性和阴性预测值分别为89.89%、33.33%、85.56%、94.94%、18.18%。结论高频超声技术与X线应用于新生儿肺炎中均可达到较好的诊断效果,但高频肺部超声诊断效能较高,适用于临床新生儿肺炎诊断。

Objective To compare the application of high-frequency pulmonary ultrasound and X-ray in the diagnosis of neonatal pneumonia.Methods A total of 90 neonates with suspected pneumonia admitted to People′s Hospital of Yichun City,Jiangxi Province from January to December 2021 were selected as the research objects.High frequency lung ultrasound and X-ray examination were performed on the selected children respectively.The clinicopathological results were taken as the gold standard,and the diagnostic efficacy of the two methods was calculated and compared.Results Clinicopathological results showed that 84 cases were positive and 6 cases were negative.The examination results of high-frequency pulmonary ultrasound showed that 81 cases were positive and 4 cases were negative.The sensitivity,specificity,accuracy,positive and negative predictive values were 96.43%,66.67%,94.44%,97.59%and 57.14%,respectively.X-ray examination results showed that 75 cases were positive and 2 were negative.The sensitivity,specificity,accuracy,positive and negative predictive values were 89.89%,33.33%,85.56%,94.94%and 18.18%.Conclusion Both high-frequency ultrasound and X-ray can help to diagnose neonatal pneumonia.However,the former can achieve better diagnostic performance,and is more suitable for clinical diagnosis of neonatal pneumonia.
