Analysis of the application value of high-pressure injection type PICC catheter in CT enhanced scanning
耐高压注射型PICC导管在CT增强扫描中的应用价值分析

摘要

目的 针对CT增强扫描中应用耐高压注射型PICC导管的价值进行分析。方法 选取在我院行CT增强扫描的患者，纳入对象为2022年10月~2023年10月的120例展开研究，根据电脑双盲法对患者分成两组，60例使用静脉留置针的患者作为对照组，60例应用耐高压注射型PICC导管的患者为观察组，对比观察患者扫描不良事件、所耗时与伪影评价情况。结果 观察组扫描出现的不良事件（CT成像不佳、不舒适、穿刺点红肿、二次穿刺、对比剂过敏、注射外渗、侧支血管及反流）发生率，与对照组的发生率进行比较发现，观察组明显更低，（p＜0.05）；从进入检查室-开展CT检查的时间、检查结束后-处理通路的时间，两组相比之下，观察组所耗时更短，（p＜0.05）；对于锁骨下动脉、上腔静脉与右心房的伪影进行评价，观察组各项指标高于对照组，（p＜0.05）。结论 耐高压注射型PICC导管应用在CT增强扫描中价值极高，能够规避扫描中不良事件，缩短扫描耗时，确保图像高质量，值得推广。

Abstract

Objective To analyze the value of using high-pressure injection type PICC catheters in CT enhanced scanning.
Methods A study was conducted on 120 patients who underwent enhanced CT scans in our hospital from October 2022 to October 2023. The patients were divided into two groups using a double-blind computer method, with 60 patients using intravenous indwelling catheters as the control group and 60 patients using high-pressure injection type PICC catheters as the observation group. The adverse events, time consumption, and artifact evaluation of the patients were compared and observed.
Results The incidence of adverse events (poor CT imaging, discomfort, redness and swelling at the puncture site, secondary puncture, contrast agent allergy, injection extravasation, collateral vessels, and reflux) in the observation group was significantly lower than that in the control group (p<0.05); Compared with the observation group, the observation group took a shorter time from entering the examination room to conducting CT examination, and from the end of the examination to processing the pathway (p<0.05); For the evaluation of artifacts in the subclavian artery, superior vena cava, and right atrium, the observation group had higher indicators than the control group (p<0.05).
Conclusion   The application of high-pressure injection type PICC catheters in CT enhanced scanning has extremely high value, can avoid adverse events during scanning, shorten scanning time, ensure high image quality, and is worth promoting.
