Patients with clinical brain death following head injury are important potential cadaveric organ donors. We analyzed our series of cranial gunshot wounds with particular attention to the frequency and patterns of organ donation after fatal injuries. Sixty-six patients with gunshot wounds to the head, including 59 with intracranial involvement (43 male, average age 26 years) were seen during a 4-year period. Injuries were limited to the head in 50 of 59 patients. Overall mortality was 66 per cent. Predictors of mortality included Glasgow Coma Scale (GCS) of six or less (93%), self-inflicted gunshot wounds (75%), and computed tomography (CT) findings of bihemispheric injury (87%) or ventricular injury (82%). Of the 39 patients who died, 28 met standard criteria for brain death, and nine of these went on to organ procurement. Thirteen families refused donation, and six patients were not harvested for reasons including old age, pregnancy, suspicion of AIDS, coroner refusal, and failure to pursue consent. Principles essential to maximal organ retrieval include: 1) Recognition that patients suffering cerebral gunshot wounds represent potential organ donors and that certain factors are predictive of mortality; 2) Critical care/trauma team approach with standardized management and timely declaration of brain death; 3) Early search for family members and prompt notification of organ procurement agencies; 4) Sensitivity to cultural issues influencing donation; and 5) Programs to increase public awareness of organ donation.
头部受伤后出现临床脑死亡的患者是重要的潜在尸体器官捐赠者。我们分析了我们收治的一系列颅脑枪伤病例,特别关注致命伤后器官捐赠的频率和模式。在4年期间,共诊治了66例头部枪伤患者,其中59例有颅内损伤(男性43例,平均年龄26岁)。59例患者中有50例损伤仅限于头部。总体死亡率为66%。死亡率的预测因素包括格拉斯哥昏迷量表(GCS)评分6分及以下(93%)、自伤性枪伤(75%)以及计算机断层扫描(CT)显示双侧半球损伤(87%)或脑室损伤(82%)。在39例死亡患者中,28例符合脑死亡标准,其中9例进行了器官获取。13个家庭拒绝捐赠,6例患者因包括年龄过大、怀孕、怀疑感染艾滋病、验尸官拒绝以及未获得同意等原因未进行器官摘取。实现最大程度器官获取的关键原则包括:1)认识到颅脑枪伤患者是潜在的器官捐赠者,且某些因素可预测死亡率;2)采用重症监护/创伤团队方法,进行标准化管理并及时宣布脑死亡;3)尽早寻找家庭成员并及时通知器官获取机构;4)对影响捐赠的文化问题保持敏感;5)开展提高公众器官捐赠意识的项目。
