摘要
目的观察右美托咪定用于急诊科小儿清创缝合术的镇静效果。方法选取2014年1月-2015年3月我院急诊科需清创缝合且难以配合的小儿40例,将其随机分为两组,每组20例,水合氯醛组（A组）和右美托咪定组（B组）。A组以10%水合氯醛0.5 ml/kg灌肠,B组以2μg/kg右美托咪定喷鼻,达镇到静效果后在2%利多卡因局部麻醉下行清创缝合术。监测比较两组患儿用药前后的心率（HR）、呼吸频率（RR）、末梢血氧饱和度（Sp O2）,观察镇静效果,进行Ramsay镇静评分,记录达到镇静所需时间及苏醒时间,并记录用药后患儿的不良反应。结果两组患儿用药后均能配合完成清创缝合术,B组镇静效果优于A组,清创缝合术后恢复所需时间短于A组,B组患儿无不良反应记录,A组患儿有1例出现恶心、呕吐不适。结论右美托咪定喷鼻用于急诊科小儿清创缝合术的镇静治疗效果确切,起效快、苏醒时间短,无明显不良反应,值得临床推广应用。
