Traumatic WoundsTraumatic Wounds Virtually all wounds are contaminated with bacteria, only a
small fraction (4.5-6.3%) developed traumatic wound
Best way to prevent wound infection Thorough wound cleansing
Appropriate closure (consider delayed primary closure in high-risk wound)
Radiographic imaging to evaluate foreign body
Appropriate antibiotic prophylaxis

When to Give Prophylactic Antibiotics for Traumatic WoundWhen to Give Prophylactic Antibiotics for Traumatic Wound
Available data do not support prophylactic antibiotics in simple Available data do not support prophylactic antibiotics in simple wounds, but recommended in high-risk situations:
Immunocompromised patients (eg, poorly controlled p p ( g, p ydiabetes, steroid use, AIDS)
Open fractures or wounds into joints
Wounds involving tendons or cartilage
Grossly contaminated wounds that cannot be adequately y q ycleaned, esp. retained foreign body
Puncture wounds and crush injuries
Bite wounds
Oral wounds
Wounds with a significant delay (> 18 hours)Moran GJ, et al. Infect Dis Clin N Am 2008;22:117-43.

Prophylactic Antibiotics for Traumatic WoundProphylactic Antibiotics for Traumatic Wound Most settings for traumatic wound
Cloxacillin, dicloxacillin
1st cephalosporin: cephalexin
Grossly contaminated wounds, devitalized wound in immunocompromised patients:
Amox/clav
Intraoral wounds Penicillin 3-5 days for prophylaxis
7 10 days for treatment Bite wound Amox/clav
7-10 days for treatment of established infection

Comparison of the efficacy of ceftibuten and norfloxacin in the treatment of acute gastrointestinal infection in children
A prospective randomized study at an ID hospital in Thailand. Ceftibuten was compared with norfloxacin, both given orally for 5 days for treatment of acute gastroenteritis in children.
170 cases were included: 88 cases were treated with ceftibuten and 170 cases were included: 88 cases were treated with ceftibuten and 82 cases with norfloxacin.
No statistically significant differences in either comparison (p > 0.05). Neither complications nor clinical relapses were observed.
