RESUMEN
PURPOSE: The management of post-surgical subdural empyema and subdural abscess is not standardised. The objective was to analyse the efficacy and safety of oral sequential therapy (OST). METHODS: Retrospective observational study in a tertiary hospital in Vigo (Spain). We included adult patients with subdural abscess or epidural empyema with microbiological isolation. Clinical and demographic variables, isolated microorganisms and treatment regimens were included, as well as mortality and adverse effects during the follow-up period. RESULTS: Thirty patients were reviewed, two died due to causes other than infection. Six-month recurrence rate was 2/28 and all other patients (26/28) had clinical cure at the end of the treatment. The commonest isolated microorganisms were Gram-positive, especially Staphylococcus aureus. The most widely used oral antibiotic was trimethoprim-sulfamethoxazole (80%). No side effects related to oral treatment were observed. CONCLUSION: After adequate source control, OST can be a safe practice in the management of post-surgical epidural abscess and subdural empyema.
