探析临床检验在诊断小儿肺炎支原体感染中的应用价值(1)
[摘要] 目的 研究臨床检验在诊断小儿肺炎支原体感染中的应用价值。方法 方便选取2017年11月—2019年12月间95例该院收治的疑似小儿肺部支原体感染患儿作为研究对象，均行血细胞分析、血生化检验、冷凝集试验、血尿常规检验、痰及细菌培养等临床检验，以病理结果作为“金标准”，统计检查结果，对比各项检查单独及联合诊断小儿肺部支原体感染的诊断效能[准确度(ACC)、灵敏度(SEN)、特异度(SPE)。结果 该组共95例疑似小儿肺部支原体感染患儿，病理诊断显示，小儿肺部支原体感染患儿63例，非小儿肺部支原体感染患儿32例;血细胞分析诊出阳性58例，其中真阳性54例;血生化检验诊出阳性61例，其中真阳性53例;冷凝集试验诊出阳性62例，其中真阳性55例;血尿常规检验诊出阳性61例，其中真阳性53例;痰及细菌培养诊出阳性61例，其中真阳性55例;联合诊断诊出阳性70例，其中真阳性62例。临床检验联合诊断小儿肺部支原体感染的SEN(98.41%)、ACC(90.53%)均较二者单独诊断高(χ2=4.932、4.220，P<0.05)。结论 血细胞分析、血生化检验、冷凝集试验、血尿常规检验、痰及细菌培养等临床检验联合诊断小儿肺炎支原体感染可降低漏诊率，提高诊断准确度、灵敏度，为小儿肺部支原体感染的诊疗提供依据。

[Abstract] Objective To study the application value of clinical tests in the diagnosis of Mycoplasma pneumoniae infection in children. Methods Ninety-five children with suspected pulmonary mycoplasma infection (from November 2017 to December 2019) admitted to our hospital were convenient selected as the research objects. All of them underwent blood cell analysis， blood biochemical test， cold collection test， blood and urine routine test， sputum and bacterial culture and other clinical tests， using pathological results as the "gold standard"， statistical examination results， and comparison of the diagnostic efficacy of individual and combined diagnosis of mycoplasma infection in children [accuracy (ACC)， sensitivity (SEN)， specificity (SPE)]. Results There were 95 children with suspected pulmonary mycoplasma infection in this group. Pathological diagnosis showed 63 children with pulmonary mycoplasma infection and 32 children with non-pediatric pulmonary mycoplasma infection; blood cell analysis showed positive 58 cases， of which true 54 cases were positive; 61 cases were positive by blood biochemical test， of which 53 cases were true positive; 62 cases were positive by cold set test， including 55 cases were true positive; 61 cases were positive by routine blood urine test， including 53 cases were true positive; sputum and bacterial culture diagnosed positive 61 cases， of which 55 were true positives; combined diagnosis diagnosed 70 positive cases， of which 62 were true positives. The combined diagnosis of SEN (98.41%) and ACC (90.53%) in the combined diagnosis of pediatric pulmonary mycoplasma infection by clinical tests were higher than those diagnosed alone (χ2=4.932，4.220，P<0.05). Conclusion The combined diagnosis of mycoplasma pneumoniae infection in children with blood cell analysis， blood biochemical test， cold set test， blood and urine routine test， sputum and bacterial culture can reduce the missed diagnosis rate， improve the diagnostic accuracy and sensitivity， and provide the diagnosis and treatment of mycoplasma lung infection in children in accordance with., http://www.100md.com(张宏)
