不同采集方法对肺炎患儿痰培养标本检验的影响

Effects of Different Gathering Methods on Sputum Culture Specimen Examination in Children with Pneumonia

目的探讨采集肺炎患儿痰标本提高痰菌培养阳性率,减少退回标本留取率的方法。方法随机选择住院肺炎婴幼儿384例,分为两组。实验组采用入院后糜蛋白酶雾化后排痰机排痰或叩背后再吸痰留取痰标本的方法,对照组采用漱口后吐痰或刺激排痰留取痰标本的方法。结果实验组痰标本退回率明显低于对照组(P<0.01);痰培养结果阳性率明显高于对照组(P<0.01),具有显著性差异。结论对肺炎患儿采用吸痰法留取痰标本的方式可以大大提高病原菌阳性率,减少重留标本带来的麻烦,减少患儿痛苦。

Objective To discuss the methods of gathering sputum specimens in children with pneumonia for increasing the positive rate of sputum culture and reducing the taking rate of returning specimens. Methods 384 hospitalized babies and infants with pneumonia selected randomly were divided into two groups. The experimental group used the methods of sputum excretion by sputum elimination machine after chymotrypsin spray or percussion on back to take sputum specimens,the control group used the methods of expectoration after gargling or sputum excretion stimulated to take sputum specimens. Results The returning rate of sputum specimens in experimental group was lower obviously than the control group（P 0.01）;the positive rate of sputum culture was higher obviously than the control group（P 0.01） ,there was significance difference. Conclusion Using the sputum suction methods to take sputum specimens in children with pneumonia can greatly improve the positive rate of pathogens,reduce the hassle of re-samples left and reduce pain in children.
