Research on Effect of Amiodarone Combined with Metoprolol in Treatment of Tachyarrhythmias

目的探讨骨科导向复位钳的研制及在髌骨骨折中的初步临床应用效果.方法：自2012年2月至2016年6月,将92例髌骨骨折患者按照奇偶数字法均分为骨科导向复位钳组（A组）与点式复位钳组（B组）,各46例.两组均采用胥氏改良张力带钢丝固定法固定,粉碎性骨折加用环形钢丝结合张力带固定.A组采用骨科导向复位钳加压复位减少骨折间隙、引导克氏针置入.B组则采用点式复位钳复位,不借助任何定位导向置入克氏针.观察手术时间、克氏针首次置入位置、置入次数、透视次数、遗留的骨折端间隙,并依Bstman评分标准对膝关节功能进行评估.结果（1）骨科导向复位钳组临床优良：46/46（优良率100%）,显著髙于点式复位钳组优良：42/46（优良率91.30%）,（P=0.04,卡方检验）.（2）两组间手术时间、穿针次数及术中透视次数有统计学意义（t检验,分别为p〈0.001,p=0.03andp〈0.001）;两者间首次置钉合格和遗留间隙例数有统计学意义（分别为P〈0.001和p=0.03,卡方检验）.结论骨科导向复位钳在髌骨骨折患者手术治疗中的应用效果显著,应加以推广及应用.

Objective To discuss the clinical effect and value of amiodarone combined with metoprolol in treatment of tachyarrhythmias.Methods Convenient selection 76 cases of patients with tachyarrhythmias admitted and treated in our hospital from April 2015 to April 2016 were selected as the research objects and randomly divided into two groups with 38 cases in each,the control group were treated with simple amiodarone,while the control group were treated with amiodarone combined with metoprolol,and the difference in the clinical effect of the two methods was compared.Results After treatment,the sinus rhythm conversion rate,effective rate and onset time in the observation group were respectively94.7%,97.4%,（0.5±0.1）h,which were obviously better than those in the control group,and the differences between the two groups had statistical significance（P〈0.05）,the diastolic pressure,systolic pressure and rhythm of the heart in the observation group were respectively（75.1±11.2）mmHg,（116.2±15.4）mmHg,（72.1±13.7）time/min,and the change range before and after treatment was obviously bigger than that in the control group,and the difference between the two groups had statistical significance（P〈0.05）,and the incidence rate of adverse reactions was respectively 5.3%and 7.9%,and the difference had no statistical significance（P〈0.05）.Conclusion The effect of amiodarone combined with metoprolol in treatment of tachyarrhythmias is obvious,which is worth promotion and application.
