This study was undertaken to examine the presentation and outcomes relative to solid organ donation in patients with fatal cerebral gunshot wounds at a level I trauma center over a 7-year period. A retrospective chart review of patients with such wounds over the years 1993-99 was completed. Eighty (80) patients were considered potential solid organ donors. Of these, 28 (35%) became organ donors, yielding 97 transplantable organs. Ninety-six percent presented with a GCS of less than 6. Mean SBP on presentation was 130, ranging from 48 to 225. Median time from presentation to death was 18 hours. Intravenous fluids given over the first 6 hours averaged 4.3 liters. Pressors were required in 68% of cases, blood products in 34%. Consent rate for donation was 32% when requested by a physician and 59% when requested by an organ procurement organization (OPO) co-ordinator. No request was made in 15 cases. Patients with fatal cerebral gunshot wounds, but with solid organ donor potential, have a characteristic presentation. Those with hemodynamic stability and those whose hypotension responds promptly to treatment can be expected to have a donor potential despite their devastating brain injury. Minimal time and resources are required to support such patients. Additional organs may have been obtained if the request for donation was consistently separated from the families' notification of brain death, and if the request was initiated by an OPO coordinator rather than a physician. Further, all patients admitted with cerebral gunshot wounds and poor neurologic function should have local OPO referral, potential survival notwithstanding.
本研究旨在调查一家一级创伤中心7年间致命性脑枪伤患者的实体器官捐献情况及相关结果。完成了对1993 - 1999年此类伤口患者的回顾性病历审查。80名患者被视为潜在的实体器官捐献者。其中,28名(35%)成为器官捐献者,提供了97个可移植器官。96%的患者格拉斯哥昏迷量表(GCS)评分低于6分。入院时平均收缩压(SBP)为130,范围为48至225。从入院到死亡的中位时间为18小时。最初6小时内静脉补液平均为4.3升。68%的病例需要使用升压药,34%需要使用血液制品。医生提出请求时,捐献同意率为32%;器官获取组织(OPO)协调员提出请求时,同意率为59%。15例未提出请求。致命性脑枪伤但有实体器官捐献潜力的患者有其特征性表现。那些血流动力学稳定以及低血压对治疗反应迅速的患者,尽管有严重脑损伤,仍有望具有捐献潜力。支持这类患者所需的时间和资源极少。如果将捐献请求与向家属通报脑死亡始终分开,并且由OPO协调员而非医生发起请求,可能会获得更多器官。此外,所有因脑枪伤入院且神经功能不佳的患者,无论其潜在的生存可能性如何,都应转介至当地OPO。
