Abstract:
Objective?To investigate the preventive effect of heating pretreatment before coronary artery CTA examination on the contrast agent exudation. Methods?A total of 269 patients accepted coronary artery CTA examination in our hospital from January 1st, 2016 to June 30th, 2016 were recruited in the study. Patients were randomly divided into the observation group (temperature up to 37℃) and the control group (constant temperature 21-25℃) according to heating or no heating pretreatment, with 135 cases in the observation group and 134 cases in the control group. The 18 G retention needles were reserved before examination, and all patients accepted the coronary artery CTA examination after the injection of contrast agent iohexol. The exudation of contrast agent was observed. Results?There was 1 case of contrast agent exudation in the observation group with an exudation rate of 0.74%, and 10 cases of exudation in the control group with an exudation rate of 7.46%. The exudation rate of the observation group was lower than control group; the difference between two groups was statistically significant (χ2=7.748, P＜ 0.01). Conclusions?Contrast agent heating pretreatment can reduce the incidence of exudation of contrast agent.
