摘　　要：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 observe alteration of blood pressure and heart rate in patients injecting iodine contrast media for computed tomography（ CT） examination,and evaluate correlation between alteration of blood pressure and heart rate and relative factors. Methods The systolic pressure values,diastolic pressure values and heart rate values were recorded before and after injection of iodine contrast media for CT examination in 1327 patients and the difference between them were compared. Results Systolic pressure and diastolic pressure significantly increased after injection of iodine contrast media（ t = 15. 340,P = 0. 000,t = 7. 574,P = 0. 000）. However,there was no significant change of heart rate after injection of iodine contrast media（ t = 0. 589,P = 0. 556）. The systolic pressure increased more than 10 mm Hg in 36. 4% patients and the diastolic pressure increased more than 10 mm Hg in 32. 0% patients. There was no significant correlation between alteration of blood pressure and gender,age,history of hypertension or diabetes,volume and injection velocity of contrast media. Conclusion The blood pressure would change significantly in patients after injection of iodine contrast media for CT examination,indicating that more attention should be paid to it.
