摘　　要：目的 探讨中心静脉置管(central venous catheter, CVC)持续泵入不同滴速生理盐水对堵管概率的影响。方法 随机选择2019年12月—2020年8月在南通市海门区人民医院接受治疗的130例置管患者为研究对象,根据泵入流速分为研究组和对照组,各65例。对照组给予5.0 mL/h泵入,研究组给予2.0 mL/h泵入。比较两组患者的出血率及堵管发生情况、导管使用时间、封管时间及生理盐水用量及导管并发症发生情况。结果 两组出血总发生率比较,差异无统计学意义(P>0.05)。研究组堵管发生率显著低于对照组,差异有统计学意义(P<0.05)。研究组导管使用时间、封管时间及生理盐水用量均显著低于对照组,差异有统计学意义(P<0.05)。治疗期间,两组并发症主要表现为导管内血栓、导管功能不良及导管相关性感染,两组并发症发生率分别为6.15%、18.46%,差异有统计学意义(χ^(2)=4.561,P<0.05)。结论 CVC 2.0 mL/h生理盐水持续泵入在置管患者中应用效果较好,可有效减少堵管发生率,且并发症发生较少。Objective To explore the effects of continuous pumping of different rates of saline at central venous cath-eter(CVC)on the probability of catheter occlusion.Methods A total of 130 cathetering patients treated in Haimen Dis-trict People's Hospital of Nantong City from December 2019 to August 2020 were randomly selected as the study ob-jects,and were divided into study group and control group according to pump flow rate,with 65 cases in each group.The control group was given 5.0 mL/h pump,and the study group was given 2.0 mL/h pump.The bleeding rate,the oc-currence of tube blockage,catheter service time,tube sealing time,normal saline dosage and the occurrence of cath-eter complications were compared between the two groups.Results There was no statistically significant difference in the total incidence of hemorrhage between the two groups(P>0.05).The incidence of tube blockage in the study group was significantly lower than that in the control group,and the difference was statistically significant(P<0.05).Catheter service time,tube sealing time and saline dosage in the study group were significantly lower than those in the control group,and the differences were statistically significant(P<0.05).During treatment,the main complications in two groups were intraductal thrombosis,catheter dysfunction and catheter-related infection,with the complication rates of 6.15%and 18.46%,respectively,and the difference was statistically significant(χ^(2)=4.561,P<0.05).Conclusion Con-tinuous pumping of CVC 2.0 mL/h normal saline has good application effect in patients with catheters,which can ef-fectively reduce the incidence of tube blockage and have fewer complications.
