Study Design Combination of narrative and systematic literature reviews. Objectives Massive perioperative blood loss in complex spinal surgery often requires blood transfusions and can negatively affect patient outcome. Systemic use of the antifibrinolytic agent tranexamic acid (TXA) has become widely used in the management of surgical bleeding. We review the clinical evidence for the use of intravenous TXA as a hemostatic agent in spinal surgery and discuss the emerging role for its complementary use as a topical agent to reduce perioperative blood loss from the surgical site. Through a systematic review of published and ongoing investigations on topical TXA for spinal surgery, we wish to make spine practitioners aware of this option and to suggest opportunities for further investigation in the field. Methods A narrative review of systemic TXA in spinal surgery and topical TXA in surgery was conducted. Furthermore, a systematic search (using PRISMA guidelines) of PubMed (MEDLINE), EMBASE, and Cochrane CENTRAL databases as well as World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov (National Institutes of Health), and International Standard Randomized Controlled Trial Number registries was conducted to identify both published literature and ongoing clinical trials on topical TXA in spinal surgery. Results Of 1,631 preliminary search results, 2 published studies were included in the systematic review. Out of 285 ongoing clinical trials matching the search criteria, a total of 4 relevant studies were included and reviewed. Conclusion Intravenous TXA is established as an efficacious hemostatic agent in spinal surgery. Use of topical TXA in surgery suggests similar hemostatic efficacy and potentially improved safety as compared with intravenous TXA. For spinal surgery, the literature on topical TXA is sparse but promising, warranting further clinical investigation and consideration as a clinical option in cases with significant anticipated surgical site blood loss.
研究设计 叙述性和系统文献回顾的结合。目的 复杂脊柱手术中大量围手术期失血通常需要输血,并可能对患者的预后产生负面影响。抗纤维蛋白溶解剂氨甲环酸(TXA)的系统使用已广泛应用于手术出血的管理。我们回顾了 TXA 作为脊柱手术止血剂的临床证据,并讨论了其作为局部制剂使用以减少手术部位围手术期失血的新作用。通过对发表的和正在进行的关于脊柱手术中局部 TXA 的研究进行系统回顾,我们希望使脊柱医生了解这一选择,并提出该领域进一步研究的机会。方法 对脊柱手术中的全身 TXA 和手术中的局部 TXA 进行叙述性综述。此外,还按照 PRISMA 指南对 PubMed(MEDLINE)、EMBASE 和 Cochrane CENTRAL 数据库以及世界卫生组织国际临床试验注册平台、ClinicalTrials.gov(美国国立卫生研究院)和国际标准随机对照试验编号注册库进行了系统搜索,以确定关于脊柱手术中局部 TXA 的已发表文献和正在进行的临床试验。结果 在 1631 项初步搜索结果中,有 2 项发表的研究被纳入系统评价。在与搜索标准匹配的 285 项正在进行的临床试验中,共有 4 项相关研究被纳入并进行了综述。结论 静脉内 TXA 已被确立为脊柱手术中有效的止血剂。与静脉内 TXA 相比,手术中使用局部 TXA 具有相似的止血效果,且潜在安全性提高。对于脊柱手术,局部 TXA 的文献稀少但有前景,值得进一步临床研究,并考虑作为手术部位预计大量失血的临床选择。
