The Use of Prophylactic Antibiotics In the Management of Dog Bites

Not Recruiting

Trial ID: NCT00185939


This double blinded RCT will help to ascertain the usefulness of prophylactic antibiotics in the management of uncomplicated dog bites, utilizing currently best available antibiotics (Augmentin) and an important clinical outcome of infection. By enrolling 100-150 patients in this pilot trial as part of a k-award the investigators plan to utilize the point estimates of infection, side effects and other important outcomes and incorporate these into a cost most to determine the most cost effective management of these wounds and to determine if further study is warranted based on the findings.
