The use of bovine thrombin has been an effective approach to aiding hemostasis during surgery for over 60 years. Its use has a reported association with the development of antibodies to coagulation factors with limited evidence to the clinical significance.
The Collaborative Delphi survey methodology was used to develop a consensus on specified topic areas from a panel of 12 surgeons/scientists who have had experience with topical thrombins; it consisted of 2 rounds of a Web-based survey and a final live discussion.
Some key issues that reached consensus included: bovine, human plasma-derived and recombinant human thrombin are equally effective hemostatic agents with similar adverse event rates, and immunogenicity to a topical protein rarely translate into adverse events.
Although a risk of immunogenicity is associated with all topical thrombins, no conclusive clinical evidence is available that these antibodies have any significant effect on short- and long-term clinical consequences.
在过去的 60 多年里,使用牛凝血酶一直是一种有效的辅助手术止血的方法。据报道,它的使用与凝血因子抗体的产生有关,但临床意义的证据有限。
协作式德尔菲调查方法用于从 12 名具有局部使用凝血酶经验的外科医生/科学家小组中就特定主题领域达成共识;它由两轮基于网络的调查和一次最终的现场讨论组成。
达成共识的一些关键问题包括:牛、人血浆衍生和重组人凝血酶是同样有效的止血剂,不良反应发生率相似,局部蛋白的免疫原性很少转化为不良事件。
尽管所有局部使用的凝血酶都存在免疫原性风险,但目前尚无确凿的临床证据表明这些抗体对短期和长期的临床后果有任何重大影响。
