关于静脉切开术中的附加残留风险的公开证据仍不清楚说明肝素和柠檬酸盐添加剂的影响。我们的目的是评估柠檬酸和肝素化血液的潜在影响,以及临床化学和凝血试验所需的相对体积。

我们使用钠和锂作为替代品,模拟了标准化的静脉切开术,以量化蒸馏水中柠檬酸盐和肝素添加剂残留的风险。 我们还研究了随着柠檬酸血液和纯柠檬酸盐体积的增加对肝素化血液样本的污染对钠,钾,氯,镁,总钙和离子钙和磷酸盐的测量的影响。 同样,我们研究了随着肝素化血液量的增加而对柠檬酸血样的污染对肝素(抗Xa)活性,锂,活化的部分凝血活酶时间(APTT),凝血酶原时间(PT)和凝血酶时间(TT)的影响。 我们根据超出分析,生物学和临床意义的测量偏差解释了这些结果。

标准化静脉切开术模拟显示替代标记物浓度无显著差异。肝素化血样污染后,在柠檬酸盐血样中离子化钙的血量超过5-50μL,钠,氯化物和总钙的血量超过100-1000μL,观察到临床上的重大变化。 对纯柠檬酸盐残留物的研究表明,在稍低的体积下,结果相似。 肝素化血液残留量超过5–100μL时,显示临床上明显的凝血测试干扰。

结果表明,在标准化的静脉切开术中,肝素或柠檬酸污染是非常不可能的。然而,较小的体积足以严重违反静脉切开术指导原则而改变测试结果。
