目的探讨CT增强扫描碘对比剂注射前后血压和心率的变化特点及其与患者相关情况的相关性。方法分析1327例CT增强扫描患者注射碘对比剂前后的血压和心率变化情况,并与性别、年龄、糖尿病和/或高血压史、对比剂注射流率和用量进行相关性分析。结果注射对比剂后,患者收缩压(t=15.340,P=0.000)和舒张压(t=7.574,P=0.000)均升高,而心率变化没有统计学意义(t=0.589,P=0.556)。36.4%的患者收缩压升高>10 mm Hg,32.0%的患者舒张压升高幅度>10 mm Hg。患者的性别、年龄、糖尿病和/或高血压史、对比剂注射流率和用量等均不是收缩压、舒张压和心率变化的影响因素。结论患者注射碘对比剂后血压会发生明显变化,应密切关注。
Objective To investigate the changes of blood pressure and heart rate before and after CT contrast enhanced contrast-enhanced iodine contrast agent injection and its correlation with patients. Methods The changes of blood pressure and heart rate before and after injection of iodine contrast medium in 1327 cases of CT enhanced scanning were analyzed. Correlation analysis was made between gender, age, history of diabetes mellitus and / or hypertension, contrast agent injection rate and dosage. Results The systolic blood pressure (t = 15.340, P = 0.000) and diastolic blood pressure (t = 7.574, P = 0.000) were all increased in the control group after injection of contrast agent, but there was no significant difference in heart rate (t = 0.589, P = 0.556) . Thirty six percent of patients had systolic blood pressure> 10 mm Hg, and 32.0% of patients had an increase in diastolic blood pressure> 10 mm Hg. Patient’s sex, age, history of diabetes and / or hypertension, contrast agent injection rate and dosage are not the influencing factors of systolic blood pressure, diastolic blood pressure and heart rate. Conclusion In patients with iodine contrast agent after significant changes in blood pressure should be closely watched.
