: Transfusion of red cell concentrates is a key component of medical therapy. To investigate the complex transfusion-associated biochemical and physiological processes as well as potential risks for human recipients, animal models are of particular importance. This scoping review summarizes existing large animal transfusion models for their ability to model the physiology associated with the storage of erythrocyte concentrates. : The electronic databases PubMed, EMBASE, and Web of Science were systematically searched for original studies providing information on the intravenous application of erythrocyte concentrates in porcine, ovine, and canine animal models. : A total of 36 studies were included in the analysis. The majority of porcine studies evaluated hemorrhagic shock conditions. Pig models showed high physiological similarities with regard to red cell physiology during early storage. Ovine and canine studies were found to model typical aspects of human red cell storage at 42 days. Only four studies provided data on 24 h in vivo survival of red cells. : While ovine and canine models can mimic typical human erythrocyte storage for up to 42 days, porcine models stand out for reliably simulating double-hit pathologies such as hemorrhagic shock. Large animal models remain an important area of translational research since they have an impact on testing new pharmacological or biophysical interventions to attenuate storage-related adverse effects and allow, in a controlled environment, to study background and interventions in dynamic and severe disease conditions.
输注浓缩红细胞是医学治疗的重要组成部分。为了研究与输血相关的复杂生化和生理过程以及对人类受者的潜在风险,动物模型尤为重要。本范围综述总结了现有的大型动物输血模型,以评估其模拟与红细胞浓缩储存相关的生理学的能力。
系统检索了 PubMed、EMBASE 和 Web of Science 电子数据库,以获取关于猪、绵羊和犬动物模型中静脉内输注红细胞浓缩物的原始研究的信息。
共有 36 项研究纳入分析。大多数猪的研究评估了出血性休克的情况。猪模型在早期储存期间的红细胞生理方面表现出高度的生理相似性。发现绵羊和犬的研究模型可模拟人红细胞储存 42 天的典型方面。只有四项研究提供了红细胞 24 小时体内存活的数据。
虽然绵羊和犬模型可以模拟典型的人类红细胞储存长达 42 天,但猪模型在可靠地模拟双重打击病理方面表现出色,如出血性休克。大型动物模型仍然是转化研究的一个重要领域,因为它们可以测试新的药理学或生物物理干预措施来减轻与储存相关的不良反应,并在受控环境中研究动态和严重疾病情况下的背景和干预措施。
