研究目的:

血液灌流联合血液透析(HAHD)的传统预冲过程复杂、耗时且资源消耗大。我们旨在通过系统评估其操作效率、管路清洁度、临床疗效和临床安全性,开发并验证一种标准化、高效且安全的串联预冲方案。  

Objectives of Study:

Conventional priming for Hemoadsorption Combined with Hemodialysis (HAHD) is complex, time-consuming, and resource-intensive. We aimed to develop and validate a standardized,efficient, and safe tandem priming protocol by systematically evaluating its operational efficiency,circuit cleanliness, clinical efficacy and clinical safety.

干预措施:

传统预冲方法:按照标准流程,HA130灌流器和Fx10透析器分别进行预冲。具体步骤如下: 1. 灌流器预冲:夹闭透析器侧;灌流器进行动态肝素化处理,包括以100 mL/min的速度用含6,250 U肝素的肝素盐水(2500 mL)缓慢冲洗,随后以50 mL/min的速度用含12,500 U肝素的肝素盐水(500 mL)缓慢冲洗,最后以250 mL/min的速度用500 mL生理盐水快速冲洗; 2. 透析器预冲:夹闭灌流器侧;透析器根据TSHNA 0006-2023标准进行预冲,通过用800 mL生理盐水冲洗血液腔以去除空气; 3. 连接透析液管路以冲洗透析液腔并去除外部空气,随后通过跨膜压力,使用200 mL生理盐水进行10分钟的闭环循环,完成整个过程。

干预措施代码:

Intervention:

Traditional priming method:Following standard guidelines, the HA130 cartridge and Fx10 filter were primed separately. The procedure was as follows: 1.Cartridge priming:the filter side was clamped; the cartridge underwent a dynamic heparinization process involving a 100 mL/min slow flush with 2500 mL of heparinized saline (containing 6,250 U of heparin), followed by a 50 mL/min slow flush with 500 mL of heparinized saline (containing 12,500 U of heparin), and a final 500 mL fast flush with normal saline at 250 mL/min; 2.Filter priming:the cartridge side was clamped; the filter was primed according to the TSHNA 0006-2023 standard, which involved flushing the blood compartment with 800 mL of normal saline to remove air; 3.Final circuit reparation:the dialysate lines were connected to rinse the dialysate compartment and remove external air, followed by a 10-minute closed-loop recirculation with 200 mL of normal saline by applying transmembrane pressure to complete the process.

干预措施:

采用改良预冲方法二预冲:1. 慢冲阶段:(500 mL肝素化生理盐水)以100 mL/min流速预冲;2. 快速冲洗阶段:2000mL生理盐水以250 mL/min流速预冲;3. 透析器弥散:用200 mL正常生理盐水进行最终10分钟闭环循环以完成整个流程。

干预措施代码:

Intervention:

The Second modified priming as follows: 1. The slow-prime phase (a fixed volume of 500 mL of heparinized saline) was delivered at the designated variable flow rate 100 mL/min; 2. The fast-flush phase (the designated variable volume of 2000 mL of saline) was delivered at the fixed flow rate of 250 mL/min; 3. Rinsing of the dialysate compartment, followed by a final 10-minute closed-loop recirculation with 200 mL of normal saline to complete the process.
