目的探讨血常规联合C反应蛋白(CRP)在儿童病毒性感染、细菌性感染及支原体感染中的诊断价值。方法选取儿科疾病患儿264例为观察组,264例健康体检儿童为对照组,对两组儿童进行血常规和CRP检验,观察两组儿童的差异,分析血常规和CRP对儿科疾病患儿的临床诊断价值及对不同类型疾病患儿的诊断敏感度、特异度。结果观察组儿科疾病患儿的血常规、CRP检验指标出现明显差异,非严重疾病患儿占51.14%,严重疾病患儿占48.86%,严重疾病患儿的白细胞(WBC)和CRP检验结果均明显高于非严重疾病患儿,差异有统计学意义(P<0.05);严重疾病患儿与非严重疾病患儿采用WBC和CRP联合检验的敏感度与特异度分别为61.50和91.60%。依据患儿不同感染类型分为病毒性感染、细菌性感染及支原体感染,不同感染类型患儿采用两种检验方法联合检验的敏感度与特异度差异具有统计学意义(P<0.05)。结论对患儿进行血常规与CRP联合检验,能够有效减少患儿抗生素滥用情况的发生,提高患儿临床诊断准确性。
Objective To investigate the diagnostic value of blood combined with C-reactive protein (CRP) in children with viral infection, bacterial infection and mycoplasma infection. Methods Two hundred and sixty-four children with pediatric diseases were selected as the observation group and 264 healthy children as the control group. Blood and CRP levels were measured in both groups. The differences between the two groups of children were observed. Clinical diagnostic value and diagnosis of different types of diseases in children with sensitivity, specificity. Results The blood routine and CRP test of children with pediatric diseases in observation group were significantly different. 51.14% of children with non-serious diseases and 48.86% of children with severe diseases were observed in the observation group. The results of WBC and CRP in children with severe diseases were all significant The difference was statistically significant (P <0.05). The sensitivity and specificity of the combined test of WBC and CRP in children with severe diseases and non-serious diseases were 61.50 and 91.60% respectively. According to different types of infection in children with viral infection, bacterial infection and mycoplasma infection, different types of infection in children with two test methods combined test the sensitivity and specificity of difference was statistically significant (P <0.05). Conclusion The combination of blood test and CRP in children can effectively reduce the incidence of abuse of antibiotics in children and improve the accuracy of clinical diagnosis in children.
