摘要

目的评价应用不同流速的生理盐水不同剂量对血液净化患者体外循环管路和滤器的冲洗效果。方法采用500 ml、800 ml生理盐水，分别以100 ml/min、300 ml/min和100～300 ml/min的速度冲洗管路和滤器，检测3种方法对体外循环管路和滤器中气体和微粒的清除效果。结果 100 ml/min冲洗速度对清除滤器和管路中的气体效果好，300 ml/min的冲洗速度对滤器和管路中的微粒清除效果好，100～300 ml/min的序贯式冲洗方法则能够同时清除滤器和管路中的气体和微粒。结论 100～300 ml/min的序贯式冲洗方法是适用于滤器和管路冲洗的有效方法。

Abstract

Objective To evaluate the removal efficiency of gas and particles in extracorporeal circulation tubes and filters for hemodialysis by physiological saline with different flow velocity. Methods To irrigate the tubes at the speed of 100 ml/min, 300 ml/min and 100~300 ml/min with 800 ml physiological saline, and to assess the removal efficiency of gas and particles in the extracorporeal circulation tubes and filters. Results With the irrigation speed of 100 ml/min, we got the best removal result for gas; with the irrigation speed of 300 ml/min, we got the best removal result for particles; and with the sequential irrigation speed of 100~300 ml/min, we got the ideal removal result for both gas and particles. Conclusion The sequential irrigation method at 100~300 ml/min speed is the most effective way to wash the extracorporeal circulation tubes and filters for hemodialysis.
