2013年某院儿童哮喘急性发作住院患儿的病原特点分析

目的：了解2013年某院儿童支气管哮喘急性发作的病原分布特点。方法回顾性分析2013年该院收治的哮喘急性发作的447例住院患儿的临床资料，采用 SPSS 19．0进行数据分析。结果细菌检出率43．8％，其中肺炎链球菌检出率25．5％，居细菌检出首位；25例患儿完成了肺泡灌洗液细菌培养，阳性率44．0％，与痰培养检出结果差异无统计学意义（ P＞0．05）；呼吸道常见7种病毒检出率27．3％，其中呼吸道合胞病毒检出率18．8％，居常见7种病毒检出首位，小于1岁组病毒检出率较高，各年龄组检出率差异有统计学意义（ P＜0．05）；肺炎支原体检出率23．5％，未检出肺炎衣原体。结论该院儿童哮喘急性发作与呼吸道感染密切相关，细菌检出率在各年龄组均较高。

Analysis of etiological agents in children with asthma exacerbation in 2013

Objective To investigate the distribution of etiological agents in children with asthma exacerbation in Chongqing during 2013 .Methods Four hundred and forty seven cases of hospitalized children with asthma exacerbation in 2013 in Children′s Hospital of Chongqing Medical University were retrospectively analyzed in SPSS19 .0 software .Results Among the 447 children with asthma exacerbation ,the percentage of bacteria was 43 .8% ,streptococcus pneumonia(SP)(25 .5% ) was the most common bacteria .Among the 25 cases with bacteria culture of bronchoalveolar lavage ,the positive rate was 44 .0% ,and the difference to sputum culture was not significant (P>0 .05) .The positive rate of 7 common respiratory viruses was 27 .3% ,RSV accounted for 18 .8% ,and it was the most common virus .The virus infection rate was higher in the groups below one years old ,and compared each groups′virus detection rates ,the difference was significant (P< 0 .05) .The positive rate of mycoplasma pneumoniae was 23 .5% ,chlamydia pneumonia was not detected .Conclusion Asthma exacerbation in children is closely related to respiratory infec‐tion .Bacteria detection rate was high in all ages ,which suggests that bacterial infection is an important factor in asthma exacerbation that can′t be ignored .
