目的 分析创伤评分对颌面部爆炸伤预后的预测作用。方法 采用雷管爆炸和钢珠弹使犬面部致伤 ,并严格控制受伤部位和范围。观察致伤局部伤情并记录动物伤后的生理变化 ,分析生理和解剖评分对爆炸伤预后的预测作用。结果 有 1/ 3的动物在致伤后最终死亡 ,死亡组动物的院前指数 (PHI)较存活组高 ,而两组的简明损伤定级 (AIS)值相同 ,提示不应单纯依赖AIS作为面部爆炸伤严重度的评估指标。结论 在对面部爆炸伤的创伤评分中 ,应综合应用生理评分和AIS分析创伤预后并指导临床救治
Objective To analyze the predictive value of trauma score on the prognosis of maxillofacial explosive injury. Methods Detonating detonators and steel ball shells caused facial injuries in dogs and strictly controlled the injured parts and areas. Observe the local injury and record the physiological changes after the animal injury, and analyze the predictive value of the physiological and anatomic score on the prognosis of the explosive injury. Results One-third of the animals eventually died after the injury, and the PHI of the deceased animals was higher than that of the survivors, while the Concise Lesion Rating (AIS) values of the two groups were the same, suggesting that AIS alone should not rely on Assessment of the severity of facial explosive injury. Conclusion In trauma scoring of facial explosive injury, we should synthetically use physiological score and AIS to analyze trauma prognosis and guide clinical treatment
