Abstract: 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.
