新生儿肺炎两种取样方法痰培养结果分析

目的:探讨两种取样方法对新生儿肺炎痰培养结果的影响。方法:对124例新生儿肺炎患者同步进行两种方法取痰样培养。结果:124例新生儿肺炎呼吸道病原细菌培养总阳性率为43.55%,咽喉深部吸痰培养阳性49例,阳性率为38.28%,喉镜直视下声门处取痰培养阳性59例,阳性率为47.58%,两种方法比较,差异有统计学意义(P<0.05)。咽喉深部吸痰培养出致病菌55株,喉镜直视下声门处取痰培养出致病菌61株,两种方法比较,差异无统计学意义(P>0.05)。结论:两种方法各有利弊,喉镜直视下声门处取痰培养阳性率高,可有效避免口咽部寄居菌的污染,方法简单、安全、对指导新生儿肺炎抗菌药物的合理应用意义较大,且对技术要求不高,在基层医院能广泛开展。

Analysis on two different sampling methods for sputum cultivation in neonatal pneumonia

Objective To discuss the effect of different sampling methods on sputum cultivation results in neonatal pneumonia.Method Using different sampling methods to get the sputum sample for cultivation at the same time in 124 neonatal pneumonia cases.Results The total positive rate was 43.55% in 124 cases,49 cases were positive in the deep laryngopharynx samples,the positive rate was 38.28%,59 cases were positive in glottis samples with laryngoscope help,the positive rate was 47.58%,there was statistical difference between the two methods.There were 55 bacterial colonies in the deep laryngopharynx samples and 61 bacterial colonies in the glottis samples,there was no statistical difference between the two methods.Conclusion Different methods with different advantages and disadvantages,we can get higher positive rate sample in glottis with laryngoscope help,avoid the contaminated of buccal and faucal bacteria,the method is simple and safe,it can conduct the normative administration of antibiotic in neonatal pneumonia,it can be actualized in junior hospital widely.
