Dynamically titrated crystalloids are the standard of care for burn shock resuscitation. There are theoretical concerns that the adjunctive use of allogeneic plasma may perturb the patient's coagulation and inflammation status deleteriously. It was hypothesized that plasma-inclusive resuscitation (PIR) would not be associated with prothrombotic changes relative to baseline after thermal injury.
Patients admitted to a regional burn center who were treated with PIR as part of their burn resuscitation were enrolled. Whole blood samples were analyzed prospectively via rapid thromboelastography and rotational thromboelastometry to assess for coagulopathy at four time points throughout their acute burn resuscitation. The mixed-effect model for repeated measures followed by Tukey's post hoc test for comparisons was used to examine group differences.
There were 35 patients in the analysis. Most were male (74.3%) with a median age of 43 y (32-55), concomitant inhalation injury of 28.6%, total body surface area burn size of 34% (27%-48.5%), and the overall mortality of the cohort was 28.6%. There were no transfusion reactions or thrombotic events. There were no differences in thromboelastography or rotational thromboelastometry parameters overall or when stratified by mortality, total body surface area burn, and inhalation injury. There were no significant differences between the fibrinolytic phenotypes over time.
Data suggest that PIR was not associated with prothrombotic or lytic changes in burn patients relative to baseline. Further research is needed to confirm these findings and evaluate efficacy of PIR in acute burn resuscitation.
在烧伤休克复苏中,动态滴定晶体液是标准的治疗方法。有理论上的担忧认为,添加异体血浆可能会对患者的凝血和炎症状态产生有害影响。本研究假设,相对于热损伤后的基线水平,包含血浆的复苏(PIR)不会与促血栓形成变化相关。
纳入在区域性烧伤中心接受 PIR 治疗的烧伤患者。通过快速血栓弹性描记术和旋转血栓弹性测定法对全血样本进行前瞻性分析,以在急性烧伤复苏的四个时间点评估凝血功能障碍。采用重复测量混合效应模型,随后进行 Tukey 事后检验进行组间比较。
共纳入 35 例患者进行分析。大多数患者为男性(74.3%),中位年龄为 43 岁(32-55 岁),伴有吸入性损伤占 28.6%,总体表面积烧伤占 34%(27%-48.5%),死亡率为 28.6%。没有发生输血反应或血栓事件。总体上和按死亡率、总体表面积烧伤和吸入性损伤分层时,血栓弹性图或旋转血栓弹性测定参数均无差异。纤维蛋白溶解表型在不同时间点也没有显著差异。
数据表明,与基线相比,PIR 并未导致烧伤患者发生促血栓形成或纤溶变化。需要进一步的研究来证实这些发现,并评估 PIR 在急性烧伤复苏中的疗效。
