Prevention of infections associated with combat-related eye, maxillofacial, and neck injuries.
The percentage of combat wounds involving the eyes, maxillofacial, and neck regions reported in the literature is increasing, representing 36% of all combat-related injuries at the start of the Iraq War. Recent meta-analysis of 21st century eye, maxillofacial, and neck injuries described combat injury incidences of 8% to 20% for the face, 2% to 11% for the neck, and 0.5% to 13% for the eye and periocular structures. ⋯ Further studies of bacterial infection epidemiology and postinjury antimicrobial use in combat-related injuries to the eyes, maxillofacial, and neck region are needed to improve evidence-based medicine recommendations. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections associated with Combat-related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

During combat operations, extremities continue to be the most common sites of injury with associated high rates of infectious complications. Overall, ∼ 15% of patients with extremity injuries develop osteomyelitis, and ∼ 17% of those infections relapse or recur. The bacteria infecting these wounds have included multidrug-resistant bacteria such as Acinetobacter baumannii, Pseudomonas aeruginosa, extended-spectrum β-lactamase-producing Klebsiella species and Escherichia coli, and methicillin-resistant Staphylococcus aureus. ⋯ We emphasize postinjury antimicrobial therapy, debridement and irrigation, and surgical wound management including addressing ongoing areas of controversy and needed research. In addition, we address adjuvants that are increasingly being examined, including local antimicrobial therapy, flap closure, oxygen therapy, negative pressure wound therapy, and wound effluent characterization.

Combat-related injuries to the central nervous system (CNS) are of critical importance because of potential catastrophic outcomes. Although the overall infection rate of combat-related CNS injuries is between 5% and 10%, the development of an infectious complication is associated with a very high morbidity and mortality. This review focuses on the prevention of infections related to injuries to the brain or the spinal cord and provides evidence-based medicine recommendations from military and civilian data for the prevention of infection from combat-related CNS injuries. ⋯ Areas of focus include elimination of cerebrospinal fluid leaks, wound coverage, postinjury antimicrobial therapy, irrigation, and debridement. Given that these recommendations are not supported by randomized control trials or adequate cohort studies in a military population, further efforts are needed to determine the best treatment strategies.

Bleeding often poses significant life-threatening situations to surgeons. After trauma, a one-third of civilian casualties and one-half of combat casualties die as a result of exsanguination. Recent advances have provided promising new hemostatic dressings that are applied directly to severely bleeding wounds in the pre-hospital period. ⋯ The mRDH trauma/surgery bandage was able to increase survival of patients after high-grade liver trauma with an associated coagulopathy. Additional clinical studies support this result.

Despite advances in resuscitation and surgical management of combat wounds, infection remains a concerning and potentially preventable complication of combat-related injuries. Interventions currently used to prevent these infections have not been either clearly defined or subjected to rigorous clinical trials. ⋯ These guidelines focus on care provided within hours to days of injury, chiefly within the combat zone, to those combat-injured patients with open wounds or burns. New in this update are a consolidation of antimicrobial agent recommendations to a backbone of high-dose cefazolin with or without metronidazole for most postinjury indications and recommendations for redosing of antimicrobial agents, for use of negative pressure wound therapy, and for oxygen supplementation in flight.
