摘　　要：目的探讨静脉给予右美托咪定对罗哌卡因蛛网膜下腔阻滞效果的影响。方法选择2013年3月-2015年9月我院收治的内外痔患者80例,分为两组,各40例,对照组使用单纯蛛网膜下腔阻滞,观察组在实施蛛网膜下腔阻滞前静脉给予右美托咪定,比较两组麻醉起效时间,以及术中发生的不良反应。结果观察组感觉神经阻滞及运动神经阻滞起效时间均快于对照组（P〈0.05）,观察组发生寒颤、心动过缓及镇痛不全的比例低于对照组（P〈0.05）。结论右美托咪定能有效提前罗哌卡因蛛网膜下腔阻滞起效时间,减少术中并发症。Objective To investigate the effect of intravenous dexmedetomidine given spinal anesthesia ropivacaine.Methods 80 cases were divided into two groups from March 2013 to September 2015,40 cases in each group,the control group were used spinal anesthesia,the observation group were used the method under the subarachnoid space barrier lag before intravenous dexmedetomidine,then onset time of anesthesia between the two groups,as well as adverse reactions surgery were compared.Results The sensory nerve block and motor block onset time in the observation group were faster than control group（P〈0.05）,the ratio of had chills,bradycardia and incomplete analgesia in the observation group were lower than control group（P〈0.05）.Conclusion Dexmedetomidine will be able to effectively advance ropivacaine spinal anesthesia onset time,it can reduce intraoperative complications.
