地西泮联合美托洛尔应用于64层螺旋CT冠状动脉成像心率干预

Combined use of Diazepam and metoprolol to control heart rate during 64-slice spiral CT coronary angiography

目的:观察64层螺旋CT冠状动脉成像应用地西泮联合美托洛尔干预心率的效果。方法:将100例患者按预约检查先后顺序,随机分为实验组和对照组各50例,在造影检查前与受检者充分沟通后,遵医嘱给予实验组受检者联合应用地西泮注射液及盐酸美托洛尔片;对照组单纯口服盐酸美托洛尔片。观察两组受检者心率控制时间及检查时心率波动范围、检查成功率及不良反应发生率之间的差异。结果:实验组受检者心率控制时间明显比对照组短(P<0.01);检查过程中心率波动幅度>10次/min的发生率明显低于对照组(P<0.05);检查成功率明显高于照组高(P<0.05);不良反应发生率两组受检者之间差异无统计学意义(P>0.05)。结论:在做好安全防护的前提下,适当的联合应用地西泮注射液及盐酸美托洛尔片可快速有效地控制受检者紧张情绪,增强控制心率效果,优化工作流程,使设备、人力资源得到最大程度利用。

Objective：To observe the outcome of heart rate control with combined use of diazepam injection and oral metoprolol in 64-slice spiral CT coronary angiography.Methods：100 patients were divided into experimental group and control group according to their examination sequence at random 50 patients in each group.Patients were fully communicated and consents were signed.Diazepam injection plus oral metoprolol were prescribed in experimental group before examination;oral metoprolol was given in control group.The differences in heart rate control time,heart rate flotation and examination success rate,incidence rate of adverse reaction were compared.Results：Heart rate control time was spastically significant short in experimental group than in control group（P〈0.01）.Heart rate flotation higher than 10 bpm was less common in experimental group.Examination success rate was higher in experimental group（P〈0.05）.The difference was not statistically significant in incidence rate of adverse reaction.Conclusion：Combined use of diazepam injection and oral metoprolol can rapidly reduce patients＇ mental stress,enhance heart rate control effect,optimize working process,and greatly improve the cost-effect of equipment and human recourses.
