作者们为确定急性化脓性中耳炎的致病菌在鼻咽部和中耳的分布情况,对505例从初生到7岁的患儿进行了中耳和鼻咽部分泌物的细菌学检查,并对其致病性和对青霉素治疗的敏感性作了分析。方法:将患儿无选择地分成三组:鼓膜切开组(151例),青霉素V治疗组(190例)和两者结合治疗组(164例)。分泌物标本的采集来自中耳/耳道的297例,来自鼻咽部/鼻腔的432例。棉拭子拭取后插入含有营养肉汤的消毒玻璃管中
To determine the distribution of pathogenic bacteria in acute suppurative otitis media in the nasopharynx and the middle ear, the authors performed a bacteriological examination of the middle ear and nasopharyngeal secretions in 505 children from birth to 7 years of age Its pathogenicity and sensitivity to penicillin treatment were analyzed. Methods: The children were randomly divided into three groups: eardrum excision group (151 cases), penicillin V treatment group (190 cases) and both combined treatment group (164 cases). Collection of secretions samples from the middle ear / ear canal 297 cases, from nasopharynx / nasal 432 cases. Swab the swab and insert into a sterile glass tube containing nutrient broth
