AbstractThe catastrophic wildfires of February 2009 in Victoria, Australia killed 173 people and hospitalised 18 adults with burns. We conducted a case-control study of wildfire victims (WFVs) compared to routine burns patients to assess early differences in bacteriology. Demographic, outcome and bacteriology data (for the first 72 h) were prospectively collected on all 18 WFVs, and compared to those of 36 RBPs matched 2:1 for age, gender, burns severity (total body surface area ≥20%) and ICU admission. We found that WFVs had more positive cultures overall (10/18 [56%] vs 7/36 [19%], p=0.04), and we cultured more Gram negative bacteria from wounds (11/13 [85%] vs 3/12 [25%], p=0.005). Although WFVs were more likely to culture Enterobacteriaceae (5/18 vs 2/36) and Aeromonas spp. (3/18 vs 1/36), and less likely to culture Staphylococcus aureus (2/18 vs 6/36), these differences were not statistically significant. Given the predominance of Gram negative organisms cultured from WFVs, our routine burn wound prophylaxis (intravenous cephazolin) would have been inadequate in the WFV group. We suggest that an alternative regimen of oxacillin/nafcillin/flucloxacillin plus gentamicin (or a fluoroquinolone if renal impairment present) may be more appropriate for burn wound prophylaxis in this complex group of patients.Crown Copyright © 2012.
