Abstract

Background: Acute rhinosinusitis (ARS) is one of the common diseases of upper respiratory tract infection in children. Bacterial infection is a significant aggravating factor in pediatric ARS. In this research, our goal was to detected the bacterial flora and antibiotic sensitivity of ARS in Chinese children.

Methods: We recruited 133 children with ARS between January 2020 and January 2022 from our hospital. Sinus secretion were collected and cultured for Gram stain as well as antimicrobial susceptibility tests.

Results: Moraxella catarrhalis, Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas aeruginosa were detected in order in children with ARS, of which 25% were negative for bacterial culture and 10% were positive for two strains. Amoxicillin and clavulanate potassium were useful for Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis. Quinolones are useful for Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas aeruginosa.

Conclusions: This research updates the proportion of ARS bacterial infection in children in southern China and the antibiotic sensitivity.

Keywords: ARS; Antibiotic sensitivity; Bacteriology; Children.
