The changing microbiology of neck abscesses in children: implications for antibiotic therapy.

Abstract

To provide an update on the microbiology, sensitivity rates and antibiotic prescribing patterns for superficial neck lymph node abscesses at Scotland's largest paediatric tertiary centre. Findings were compared to historical data from our institution. A retrospective case series was conducted of paediatric patients undergoing incision and drainage of a superficial neck lymph node abscess at the Royal Hospital for Children in Glasgow, from 2018 to 2021. Thirty-nine abscesses were identified. Methicillin-susceptible Staphylococcus aureus was the commonest micro-organism (28 per cent), followed by Streptococcus pyogenes (13 per cent). Eighty-two per cent of patients were administered a drug regimen containing co-amoxiclav. Only three children required a change in their antibiotics. There was a significant change in causative micro-organisms, including a decrease in S aureus and an increase in the Streptococcus anginosus group. Empirical use of co-amoxiclav is recommended. In abscesses showing no clinical improvement, second-line options such as clindamycin, cefotaxime and vancomycin should be considered.
