Abstract:
Objective:To observe the effect of medium-length intravenous catheter infusion on the intima and hemodynamics of the implanted blood vessel, in order to early detect the asymptomatic ultrasound imaging manifestations of indwelling blood vessel injury in patients, and observe the occurrence of catheter-related complications.Methods:Totally 105 patients who had medium-length venous catheters inserted through the upper arm in Huangshi Central Hospital from July to December 2021 were selected by random sampling. A self-control study was adopted. According to the time of data collection, they were divided into pre-catheterization group and the post-extubation group. Color Doppler ultrasonography was used to observe the image morphology, blood flow velocity, and blood flow of the vein intima at the outlet of the catheter tip before catheterization and after extubation, and to monitor the incidence of catheter-related complications. Among the 105 patients, 5 cases dropped out, and the effective sample size was 100 cases.Results:Among the 100 patients, before catheterization and after extubation, the vascular intima at the indwelling catheter tip showed no damages such as roughness and thickening; there was no statistically significant difference in venous blood flow velocity and the blood flow at the catheter tip before and after catheter extraction ( P>0.05) . There were 5 cases (4.76%, 5/105) of catheter-related complications. Conclusions:Medium-length intravenous catheter infusion of hyperosmolar parenteral nutrition solution does not significantly affect the morphology and hemodynamics of the intima of the implanted vessel, the implanted vessel is not damaged, and no serious complications such as catheter-related thrombosis and bloodstream infection occur, which achieve relatively safe clinical outcomes.
