Abstract

We aimed to investigate the characteristics of bacterial profiles and antibiotic sensitivity in diabetic foot ulcers before and after wound bed preparation. This study involved 423 diabetic patients with Wagner grades 1 to 4 foot ulcers. Secretion culture was performed before wound bed preparation. The observation endpoint was when the wound showed a tendency toward healing and a specialist determined that stopping antibiotic treatment would not affect wound healing. A second secretion culture was performed after the observation endpoint. We obtained results from both secretion cultures from 411 patients. The proportion of multi-drug-resistant (MDR) gram-positive bacteria was 22.0% and 47.8% before and after treatment, respectively; that for gram-negative bacteria was 3.5% and 19.2%, respectively (P < .05). Pretreatment antibiotic sensitivity of staphylococci and other gram-positive bacteria was 48.7% and 44.8%, respectively; the rates decreased significantly after treatment to 36.8% (P = .031) and 34.8% (P = .027), respectively. Pretreatment antibiotic sensitivity of common and nonfermenting rare gram-negative bacteria was 55.4% and 54.6%, respectively, which decreased substantially after treatment to 33.2% (P = .002) and 32.9...Continue Reading
