Integration of Fieldâ…¡and SiteRite5 In Vascular Ultrasound Improves One-Time Success Rate of Peripherally Inserted Central Catheter
Abstract
Medical ultrasound has been used in clinical diagnosis for decades. In recent decades, vascular stenosis or aneurysm caused by cardiovascular and cerebrovascular diseases caused growing number of deaths, and early detection of those diseases drawn increased attention. In the present study, we used the Doppler method to simulate the distribution of axial blood flow velocity in vessels with varying degrees of stenosis. Then we propose a Fieldâ…¡simulation model of ultrasonic RF signal for varying degrees of vascular stenosis. The experimental results show that the ultrasonic RF signal generated by Field â…¡ and its estimated velocity profile are concordant with the theoretical results, which shows that the simulation model of ultrasonic radiofrequency signal with narrow blood vessel established by the Field II is effective and is practical in clinical settings, such as assessing the processing methodologies and feature extraction algorithms of ultrasonic signals for blood flow. With the assitance of Field II simulation, the SiteRite5 vascular ultrasound system and the micro-catheter sheath technique were used to puncture the upper arm PICC. The patients with vascular disease were divided into two groups: observation group and comparison group. The upper arm PICC for patients in the observation group were assisted by American Bart SiteRite5 system to monitor the blood vessels and performed by micro-catheter sheath technique. In comparison group, blood vessel line PICC. The one-time success rate of total puncture, and the recovery rate of the in-observation group was significantly improved compared with comparison, and the incidence of complication was accordingly reduced.
