对因鼻塞诊断为腺样体肥大而行切除手术的55例儿童,将切除的腺样体制成组织匀浆进行定量需氧细菌培养。55例被分为两组即单纯腺样体肥大组(AH,29例)和腺样体肥大合并分泌性中耳炎组(病程>3月)(SOM,26例),两组年龄结构类似,所有病人前1月内均未接受过抗生素治疗。腺样体切除前先用金属卷棉子经鼻涂擦鼻咽部,接种于5％羊血琼脂和巧克力琼脂上,按常规进行细菌培养;腺样体切除后,立即在无菌条件下将切除标本分成几块,冻存于-70℃的
A total of 55 children who underwent resection for adenoid hypertrophy due to nasal obstruction were sacrificed and the resected adenoids were made into tissue homogenates for quantitative aerobic bacterial culture. 55 cases were divided into two groups: simple adenoid hypertrophy group (AH, 29 cases) and adenoid hypertrophy with secretory otitis media group (duration> 3 months) (SOM, 26 cases) None of the patients had been treated with antibiotics within a month before. Adeno-nasal resection with nasal swabs before the nasal swab nasal smear, inoculated on 5% sheep blood agar and chocolate agar, according to conventional bacterial culture; adenoid resection, immediately under sterile conditions will be Excised specimens were divided into several, frozen at -70 ℃
