Trauma-induced coagulopathy is a primary factor in many trauma-related fatalities. Management hinges upon rapid diagnosis of coagulation abnormalities and immediate administration of appropriate hemostatic agents. Use of crystalloids and packed red blood cells has traditionally been the core of trauma resuscitation, but current massive transfusion protocols include combination therapy with fresh frozen plasma and predefined ratios of platelets to packed red blood cells, limiting crystalloid administration. Hemostatic agents such as tranexamic acid, prothrombin complex concentrate, fibrinogen concentrate, and, in cases of refractory bleeding, recombinant activated factor VIIa may also be warranted. Goal-directed resuscitation using viscoelastic tools allows specific component-centered therapy based on individual clotting abnormalities that may limit blood product use and thromboembolic risks and may lead to reduced mortality. Because of the complex management of patients with trauma-induced coagulopathy, critical care nurses must be familiar with the pathophysiology, acute diagnostics, and pharmacotherapeutic options used to treat these patients.
创伤性凝血病是许多创伤相关死亡的主要因素。治疗关键在于快速诊断凝血异常并立即给予适当的止血剂。传统上,晶体液和浓缩红细胞的使用一直是创伤复苏的核心,但目前的大量输血方案包括新鲜冰冻血浆联合治疗以及血小板与浓缩红细胞的预定义比例,限制晶体液的输注。诸如氨甲环酸、凝血酶原复合物浓缩物、纤维蛋白原浓缩物等止血剂,以及在难治性出血情况下的重组活化因子VIIa也可能是必要的。使用粘弹性工具进行目标导向复苏可根据个体凝血异常进行以特定成分中心的治疗,这可能会限制血液制品的使用和血栓栓塞风险,并可能降低死亡率。由于创伤性凝血病患者的管理复杂,重症护理护士必须熟悉用于治疗这些患者的病理生理学、急性诊断和药物治疗选择。
