Studies are inconclusive regarding clinical outcomes after administration of recombinant activated coagulation factor VII (rFVIIa) during severe haemorrhage. The circumstances encountered during desperate haemorrhage make it difficult to include the most critically ill patients that could possibly benefit the most from such treatment into randomized controlled trials. We report our experience with rFVIIa as last-resort treatment of desperate haemorrhage when all standard treatment has failed.
Hospital charts of all consecutive patients treated with rFVIIa for desperate non-haemophilic bleeding over a 10-year period at the single institution administering rFVIIa were surveyed for treatment indications, clinical outcome, transfusion need and coagulation profiles.
Fifty-five rFVIIa treatment occasions of desperate bleeding were identified in 54 patients (median age 54 years). A single rFVIIa dose was used in 86%, and haemorrhage was considered effectively contained by immediate clinical response on 81% of occasions. Overall, 38 patients (71%) survived for over 30 days. Two thromboembolic events occurred (3.6%). The 24-h mortality in 45 rFVIIa immediate clinical responders and 10 non-responders was 2% and 50%, respectively (P = 0.0004), and the 30-day mortality was 25% and 60%, respectively (P = 0.05). Blood product use decreased with rFVIIa (P < 0.01) as did the prothrombin time (20.0-13.3 s, P < 0.0001).
The majority of unselected consecutive patients receiving rFVIIa as last-resort treatment for desperate haemorrhage were considered to have immediate clinical response as well as reduced transfusion requirements and correction of coagulation parameters. An immediate clinical response to rFVIIa may possibly be predictive of survival.
在严重出血期间给予重组活化凝血因子 VII(rFVIIa)的临床结果尚不确定。在绝望性出血期间遇到的情况使得难以将最病危的患者纳入可能最受益于这种治疗的随机对照试验中。当所有标准治疗均失败时,我们报告了使用 rFVIIa 作为绝望性出血的最后手段治疗的经验。
在单中心使用 rFVIIa 的 10 年期间,对所有连续接受 rFVIIa 治疗的非血友病性急迫性出血患者的病历进行调查,以确定治疗适应证、临床结局、输血需求和凝血谱。
在 54 例患者中,共确定了 55 例 rFVIIa 治疗的急迫性出血(中位数年龄 54 岁)。86%的患者单次使用 rFVIIa,81%的患者即时临床反应有效控制出血。总体而言,38 例(71%)患者存活超过 30 天。发生了 2 例血栓栓塞事件(3.6%)。45 例 rFVIIa 即时临床反应者和 10 例无反应者的 24 小时死亡率分别为 2%和 50%(P=0.0004),30 天死亡率分别为 25%和 60%(P=0.05)。rFVIIa 降低了血制品的使用(P<0.01),凝血酶原时间也降低(20.0-13.3s,P<0.0001)。
大多数连续接受 rFVIIa 作为绝望性出血的最后手段治疗的未选择患者被认为具有即时临床反应以及减少输血需求和凝血参数纠正。rFVIIa 的即时临床反应可能预示着生存。
