摘　　要：目的比较中等长度导管尖端置入不同位置对老年病人的影响。方法选取2020年8月至2021年10月在我院住院接受输液治疗的老年病人86例,按导管尖端位置分为对照组(n=40)和研究组(n=46)。对照组病人导管尖端位于腋静脉胸段,研究组病人导管尖端位于锁骨下静脉,置管护士使用血管超声定位导管尖端在血管内的位置,比较2组间并发症发生率的差异。结果2组年龄、性别、穿刺血管差异均无统计学意义,均未发生静脉炎及血管导管相关感染,但研究组导管堵塞的发生率及并发症总发生率明显低于对照组(P<0.05)。结论中等长度导管应用于老年病人,将导管尖端置于锁骨下静脉可有效降低导管堵塞的发生率。Objective To compare the effects of different tip positions of midline catheter positioned under ultrasound in the elderly patients.Methods A total of 86 elderly patients hospitalized in our hospital from August 2020 to October 2021 were selected.According to the position of catheter tip,they were divided into control group(n=40)and study group(n=46).The tip of the catheter in the control group was located in the thoracic segment of axillary vein,and the tip of the catheter in the study group was located in the subclavian vein.The catheterization nurse used vascular ultrasound to position the catheter tip within the blood vessel,and the incidence of the complications was compared between the two groups.Results There were no significant differences in age,gender and puncture vessels between the two groups.No one presented with phlebitis and vascular catheter-related infection,but the incidence rate of cathter obstruction and the total incidence rate of the complications in the study group was lower than that in the control group(P<0.05).Conclusions The application of medium length catheter in the elderly patients with the tip in the subclavian vein can reduce the incidence of catheter obstruction.
