Clinical study of nonionic contrast agents in the enhancement of intravenous CT / 中国生化药物杂志

ABSTRACT

Objective To evaluate the efficacy of nonionic contrast agent, CT, in intravenous enhanced scan. Methods 84 cases of patients with CT venous enhancement scanning were admitted in our hospital from January 2016 to December 2016, ioversol dosage is 80~100 mL, the injection speed is 3~6 mL/s, both in the scan and enhanced scan before 2 h, immediately after scanning after 1 h, 48 h to record vital signs, observation of the injection site, ECG, enhanced scan in the 2 h before and after 48 h enhancement scanning, blood biochemical examination and renal function tests, and immediately, in enhanced scan and scan after scan after 15 min, 1 h and 48 h in different time periods of adverse reactions were observed and recorded. Results The excellent rate of systemic tolerance was 100%, 7 cases had flushing and thermal sensation, accounting for 8.3%. Slight adverse reactions occurred in 1 cases, accounting for 1.2%. No moderate or severe adverse reactions occurred. Conclusion The use of non-ionic contrast agent CT in intravenous enhanced scan, low adverse reaction rate, high safety, and has a very important application value.
