Surgical wound infections following traumatic injury remain a source of morbidity and mortality. A simple system for estimating the risk of infectious complications was evaluated in 949 trauma patients requiring operative therapy. The majority of cases were caused by penetrating trauma (784). Truncal, neck, and extremity procedures were included. The overall wound infection rate was 7%. Infection rates were related to amount of bacterial contamination and mechanism of injury. Age, type of antibiotics, and delay time from injury to operation were not risk factors for any injury type. Wound classification, shock, blood loss, number of organs injured, and operative time were significant risk factors, but had different effects on infection rate related to injury type. Multivariate analysis revealed no significant infectious risk factors for stabwounds. Significant factors were wound class (p = 0.02) and shock (p = 0.001) for gunshot wounds, wound class (p = 0.03) and number of organs injured (p = 0.01) for blunt trauma, and blood loss (p = 0.01) for shotgun wounds. This classification system can be used to review outcome and compare trauma patient populations for infectious morbidity in a more uniform fashion.
创伤后的手术伤口感染仍然是发病和死亡的一个原因。在949例需要手术治疗的创伤患者中评估了一种简单的感染并发症风险评估系统。大多数病例由穿透性创伤引起（784例）。纳入了躯干、颈部和四肢手术。总体伤口感染率为7%。感染率与细菌污染量和损伤机制有关。年龄、抗生素类型以及受伤至手术的延迟时间对任何损伤类型都不是危险因素。伤口分类、休克、失血量、受伤器官数量和手术时间是显著的危险因素，但对与损伤类型相关的感染率有不同影响。多因素分析显示刺伤没有显著的感染危险因素。枪伤的显著因素是伤口类别（p = 0.02）和休克（p = 0.001），钝性创伤的显著因素是伤口类别（p = 0.03）和受伤器官数量（p = 0.01），霰弹枪伤的显著因素是失血量（p = 0.01）。这种分类系统可用于更统一地回顾结果并比较创伤患者群体的感染发病率。
