Abstract
Objective:To analyze the bacteriological distribution and drug resistance of nasopharynx in patients with adenoid hypertrophy complicated with secretory otitis media, and to clarify the distribution of pathogenic bacteria, so as to provide guidance and basis for antibiotic use in clinical treatment. Methods:A retrospective analysis was performed on 311 patients with adenoid hypertrophy and secretory otitis media who underwent surgical treatment in the department of otolaryngology head and neck surgery, Affiliated Hospital of Qingdao University from February 2013 to January 2020. They were divided into 3 groups by age: Group A（0-5 years old）, Group B（6-10 years old）, and Group C（11-16 years old）. The secretions from deep adenoid near the eustachian tube of the affected ear were collected during the surgery for bacterial culture and drug resistance analysis. Results:One hundred and forty-two strains of pathogenic bacteria were isolated and cultured, with a detection rate of 45.66%. Staphylococcus aureus （63 strains）, streptococcus pneumoniae （15 strains） ,streptococcus pyogenes （13 strains） and moraxella cachinella（28 strains）was the main strain.Staphylococcus aureus had high drug resistance rate to penicillin, erythromycin and clindamycin.Streptococcus pneumoniae and Streptococcus pyogenic had high resistance rates to erythromycin,clindamycin and tetracycline. The resistance rate of Moraxella catarrhalis to ampicillin and co-trimoxazole was higher. Conclusion:The main pathogens detected in patients with adenoid hypertrophy complicated with secretory otitis media are staphylococcus aureus, streptococcus pneumoniae, streptococcus pyogenes and moraxella catarrhalis. Drug resistance of different pathogens is quite different. So it is recommended to carry out extensive bacteriological detection, and select antibiotics according to the principle of rational drug use and the results of drug resistance test, so as to achieve good therapeutic effect.
