Timely correction of coagulopathy in patients with traumatic brain injury (TBI) improves mortality. Recombinant, activated factor VII (VIIa) has been identified as an effective method to correct coagulopathy in patients with TBI. We performed a retrospective study (January 1, 2008-December 31, 2009) of all patients with TBI and coagulopathy (international normalized ratio (INR) > 1.5) transferred to our Level I trauma center. Twenty-three patients with coagulopathy and TBI were transferred to our trauma center, 100 per cent sustained a fall, and 100 per cent were taking warfarin at the time of injury. Ten patients received VIIa to correct coagulopathy before transfer, whereas 13 did not. The purpose of this study was to compare outcomes in patients who received VIIa with those who did not. When comparing the VIIa group with the no-VIIa group there was no difference in age, gender, Glasgow Coma Scale score, injury severity score, transfer time, or INR at outlying facility. Both groups received one unit of plasma before arrival at our trauma center; patients in the VIIa group received a single 1.2 mg dose of VIIa at the outlying facility. Upon arrival to our trauma center the VIIa group had a lower INR (1.0 vs 3.0, P = 0.02) and lower mortality (0% vs 39%, P = 0.03). In coagulopathic patients with TBI presenting to outlying institutions with limited resources to quickly provide plasma, VIIa efficiently corrects coagulopathy before transfer to definitive care at the regional trauma center. More rapid correction of coagulopathy with VIIa in this patient population may improve mortality.
及时纠正创伤性脑损伤(TBI)患者的凝血病可降低死亡率。重组活化因子VII(VIIa)已被确认为纠正TBI患者凝血病的有效方法。我们对2008年1月1日至2009年12月31日期间转入我院一级创伤中心的所有TBI合并凝血病(国际标准化比值(INR)>1.5)患者进行了一项回顾性研究。23例凝血病合并TBI患者转入我院创伤中心,100%为跌倒所致,100%在受伤时正在服用华法林。10例患者在转运前接受VIIa纠正凝血病,而13例未接受。本研究的目的是比较接受VIIa治疗的患者与未接受VIIa治疗的患者的结局。将VIIa组与非VIIa组进行比较,两组在年龄、性别、格拉斯哥昏迷量表评分、损伤严重程度评分、转运时间或在外院时的INR方面无差异。两组在抵达我院创伤中心前均接受了1单位血浆;VIIa组患者在外院接受了单次1.2mg剂量的VIIa。抵达我院创伤中心时,VIIa组的INR较低(1.0 vs 3.0,P = 0.02),死亡率也较低(0% vs 39%,P = 0.03)。对于在资源有限、无法快速提供血浆的外院就诊的凝血病合并TBI患者,VIIa可在转运至区域创伤中心接受确定性治疗前有效纠正凝血病。在这一患者群体中,用VIIa更快速地纠正凝血病可能会降低死亡率。
