M-A | Routine anaerobic coverage for aspiration pneumonia: limited evidence of benefit
13 Mar, 2023 | 15:03h | UTCSummary: Treating aspiration pneumonia with antibiotics that cover anaerobic bacteria has become common practice in many services, but recent studies suggest that this may not necessarily improve prognosis.
Out of 2523 publications, this systematic review and meta-analysis only included one randomized control trial and two observational studies. The study found no clear benefit of anaerobic coverage and concluded that there is not enough data to evaluate the necessity of anaerobic coverage in the antibiotic treatment of aspiration pneumonia.
The authors suggest that covering anaerobic bacteria with antibiotics may not be needed as an initial treatment for aspiration pneumonia if there is no formation of abscess or empyema and the patient has good oral hygiene.
