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.
