90例急性中耳炎患儿分泌物病原菌分布及耐药性分析

Distribution and drug resistance analysis of secretion pathogens in 90 children with acute otitis media

目的:分析90例急性中耳炎患儿分泌物病原菌分布及耐药性。方法:回顾性分析90例急性中耳炎患儿的临床资料,分析所有患儿的病原菌分布情况,根据年龄将其分为A组(≤1岁,n=38)、B组(>1~3岁,n=27)和C组(>3岁,n=25),比较各组患儿的肺炎链球菌检出情况及肺炎链球菌对各抗菌药物的耐药性。结果:患儿病原菌检测阳性率为75.6%(68/90),其中,肺炎链球菌所占比例最高,为61.8%(42/68);A、B两组患儿的肺炎链球菌检出率明显高于C组(P<0.05);肺炎链球菌对不同抗菌药物的耐药率存在较大差异。结论:肺炎链球菌是<3岁急性中耳炎患儿的主要病原菌,其对不同种类抗菌药物的耐药性不同。

Objective: To analyze the pathogenic bacteria distribution and drug resistance of secretion in 90 child patients with acute otitis media. Method: The clinical data of 90 cases of acute otitis media child patients were retrospectively analyzed. The distribution of pathogenic bacteria in all child patients were analyzed. The child patients were divided into A group(less than 1 year old, n=38), B group(1 to 3 years old, n=27) and C group(more than 3 years old, n=25) according to the age. The streptococcus pneumoniae detection in each group and the streptococcus pneumoniae resistant to various antibacterial agents were compared. Result: The positive rate of pathogen detection in children was 75.6%(68/90), and the highest proportion was streptococcus pneumoniae with 61.8%(42/68). The detection rate of streptococcus pneumoniae in A and B group was significantly higher than that of C group(P<0.05). The resistance rate of streptococcus pneumoniae to different antibacterial drugs is quite different. Conclusion: Streptococcus pneumoniae is the main pathogenic bacterium in child patients with acute otitis media less than 3 years old, and different types of antibacterial drugs have different drug resistance.
