• Delayed Primary Closure (DPC)
– 4 - 6 days
Vietnam
• Kell, 1991:
–“A single injection of a broadspectrum antibiotic with a long halflife should be given prophylactically to personnel on the battlefield to provide bactericidal coverage from the earliest moment after injury occurs.”
» Used penicillins
• Somalia
– Pseudomonas and polymicrobial
• Russian Afghanistan Experience
– Clostridial
» Recommended PCN, Rifampin, Metronidazole, or Ceftriaxone
– Fullen, et al.
• Both the timing and the choice are important.

抗生素合理使用策略(英文PPT)Antibiotic stewardship in the Acute and Community setting
Why are antibiotics used inappropriately?
• Lack of knowledge of drug spectrum, dosing etc. • Lack of knowledge of adverse drug reactions and
resistance associated with antibiotics • Lack of access to diagnostic facilities
• Time pressure
– Quicker to write prescription than explain what a virus is
• Influence of pharmaceutical promotion • Habit
– The First Law of Therapeutics: “The patient is doing well; continue the antibiotics!”
Meticillin-Resistant S. aureus
• MRSA in New York*
– ineffective empiric treatment of bacterial infection at the time of its identification
– the wrong choice, dose or duration of therapy – use of an antibiotic to which the pathogen
• 75% questionable therapeutic value
Harrison and Lederberg, Antimicrobial Resistance 1998

What Bugs?
• Yom Kippur War
– Pseudomonas – 25.6% isolates – Gm Neg bacilli – 70% isolates overall
General Preventive Measures
• Adequate and Timely Resuscitation
• Early Wound Care • Antibiotics • Tetanus Immune Prophylaxis
Adequate and Timely Resuscitation
Why not?!
• Antibiotics not routinely given in the field by civilian pre-hospital personnel (EMT/paramedic model for
medic training).
• Combat medics don’t typically see wound infections during the time they care for them – may not appreciate their devastating effect.
• Debridement
– excise devitalized tissue
• Irrigation
– high pressure, solution
• Eliminate Dead Space
– fluid, blood
• Both the timing and the choice are important.
