研究目的: |
心血管手术因术中肝素化、体外循环、血液稀释及低温等因素,显著破坏凝血-纤溶系统稳态,导致患者术后出血量增加及异体输血需求升高。目前,术后失血因缺乏规范化回收技术而直接废弃,不仅加剧血液资源浪费与医疗成本负担,还可能因异体输血需求增加而诱发感染、免疫反应等并发症。本研究为一项多中心、前瞻性、随机对照临床试验,旨在通过洗涤式回收与回输术后失血,验证回收式自体输血技术降低异体红细胞输注量的临床有效性(主要有效性终点),并评估其输血安全(主要安全性终点)及医疗经济成本(次要终点),最终建立标准化操作流程以推动临床规范化应用。研究结果将优化自体血液资源利用效率,减少异体输血需求,从源头缓解血液资源紧张问题,紧扣国家“节约用血、推广自体输血”的战略导向,为医疗资源可持续发展提供循证依据。 |

Objectives of Study: |
Cardiovascular surgery significantly disrupts the hemostatic and fibrinolytic balance due to intraoperative heparinization, cardiopulmonary bypass, hemodilution, and hypothermia, often leading to increased postoperative bleeding and a heightened need for allogeneic blood transfusion. Currently, postoperative shed blood is often discarded due to the absence of standardized salvage protocols, resulting in wasted autologous blood resources, increased healthcare costs, and a higher risk of transfusion-related complications such as infection and immune reactions. This multicenter, prospective, randomized controlled trial aims to evaluate the clinical efficacy of postoperative autologous cell salvage and transfusion in reducing allogeneic red blood cell transfusion (primary efficacy endpoint), while also assessing transfusion safety (primary safety endpoint) and healthcare economic costs (secondary endpoint). The study further seeks to establish a standardized operating protocol to facilitate its clinical implementation. The results are expected to improve the utilization efficiency of autologous blood, reduce allogeneic transfusion needs, and ultimately alleviate blood supply shortages at the source—supporting the national strategy of promoting autologous transfusion and rational blood use, and contributing to the sustainable development of healthcare resources. |
