摘　　要：目的 提高老年重症患者行连续性血液净化治疗更换管路和滤器的效率和安全性。方法 将41例行连续性血液净化治疗的老年重症患者随机分为对照组20例、观察组21例。对照组按常规置换滤器与管路69例次,观察组采取双机法更换滤器与管路65例次。结果 观察组更换滤器与管路时间显著少于对照组,更换过程中血压波动值显著小于对照组(均P<0.05);心率波动值两组比较,差异无统计学意义(P>0.05)。结论 对行连续性血液净化治疗的老年重症患者采用双机法更换滤器和管路,可显著提高更换效率,患者血流动力学更稳定。Objective To improve the efficiency and safety of replacing circuit and filter in continuous blood purification(CBP)for elderly critically ill patients.Methods Forty-one elderly critically ill patients on CBP were randomly divided into a control group of 20 and an observation group of 21.The control group was given routine circuit and filter replacement for 69 times,while the observation group received 65 times of circuit and filter replacement following the double-machine replacement protocol.Results The observation group had significant reduction in circuit replacement time and smaller blood pressure fluctuations during the replacement process compared with the control group(all P<0.05).There was no significant difference in heart rate fluctuations between the two groups(P>0.05).Conclusion Application of the double-machine circuit replacement method in CBP for elderly critically ill patients can improve circuit replacement efficiency and stabilize hemodynamics.
