研究目的:

肝素作为常用的抗凝剂,其个体化剂量调整一直是临床实践中的难点。目前,肝素抗凝的主要问题包括 1.个体敏感性差异大:患者对肝素的反应受体重、肾功能、抗凝血酶III水平、基础疾病等多种因素影响,导致APTT(活化部分凝血活酶时间)短期内难以达标,抗凝不足或过度的风险较高。 2.缺乏精准预测工具:传统肝素剂量调整依赖经验性方案,缺乏科学、快速的预测方法,导致滤器寿命缩短、治疗成本增加,甚至引发出血或血栓并发症。 3.肝素负荷试验(HLT):通过固定剂量肝素注射后观察APTT升高幅度,可直观反映患者对肝素的敏感性,为个体化剂量预测提供新思路。本团队前期研究发现,HLT APTT升高倍数与肝素维持量存在显著相关性。然而,HLT的临床应用流程以及与传统肝素调节方法的对比效果仍需进一步验证。  

Objectives of Study:

Heparin, as a commonly used anticoagulant, presents ongoing challenges in individualized dose adjustment in clinical practice. The main issues in heparin anticoagulation currently include: 1. Significant individual sensitivity variation: Patient response to heparin is influenced by multiple factors such as body weight, renal function, antithrombin III levels, and underlying diseases. This often leads to difficulties in rapidly achieving target activated partial thromboplastin time (APTT) levels, increasing the risks of both under-anticoagulation and over-anticoagulation. 2. Lack of precise predictive tools: Traditional heparin dosing adjustments rely on empirical protocols and lack scientific, rapid prediction methods. This can result in shortened filter lifespan, increased treatment costs, and even bleeding or thrombotic complications. 3. Heparin Loading Test (HLT): By observing the rise in APTT after a fixed-dose heparin injection, HLT directly reflects a patient's sensitivity to heparin, offering a new approach for individualized dose prediction. Our team's preliminary research found a significant correlation between the APTT increase multiple (post-HLT) and the required heparin maintenance dose. However, the clinical application workflow of HLT and its comparative effectiveness versus traditional heparin titration methods still require further validation.
