Abstract

Abstract:

Objective

To investigate the effect of a new power PICC catheter for CT enhanced contrast access.

Methods

A total of 60 patients who had completed the catheterization of the Power PICC SOLO in Sun Yat-sen Memorial Hospital of Sun Yat-sen University on July 1, 2019 and June 30, 2020 and needed CT enhanced examination were selected. The envelope method was used for random grouping. Among them, 30 patients who used PICC as contrast access were selected as PICC group, and the remaining 30 patients were treated as routine group. Conventional high-pressure resistant vein indwelling needle was used as contrast agent channel. CT enhanced scan was performed to compare and analyze the image quality of the two groups of patients, including the overall, liver and pulmonary vascular quality, as well as collateral and artifacts.

Results

There was no statistically significant differences in the overall quality of baseline data and images between the two groups. However, the scores of sub clavicular artery, superior vena cava and right atrium in the PICC group were significantly lower than those in the conventional group (P<0.01). Collateral vessels and reflux were significantly lower in the conventional group than those in the PICC group (P<0.01).

Conclusions

The new power PICC is a safe and efficient contrast access for enhanced CT scan, with fewer adverse reactions and better image quality.
