目的 研究七氟醚联合小剂量氯胺酮麻醉在小儿斜疝手术中的效果.方法 60例年龄3～8岁择期行斜疝修补术的患儿.随机均分为两组.七氟醚复合小剂量氯胺酮组(SK组)和氯胺酮组(K组),观察两组诱导和苏醒时间.诱导时是否合作.喉痉挛、呕吐、术中体动和知晓及苏醒期躁动发生率.结果 与K组相比,SK组能较好接受诱导,诱导、苏醒时间较短.术中体动及苏醒期躁动发生率较低(P<0.05);两组呕吐和术中知晓发生率差异无统计学意义.结论 七氟醚联合小剂量氯胺酮麻醉具有麻醉诱导、苏醒快,不良反应少,能较好地应用于小儿斜疝修补术.“,”Objective To study the effect of anesthesia of sevoflurane combined small dose ketamine in children during the operation of indirect hernia. Methods Sixty children aged from 3 to 8 years old with indirect hernia were randomly divided into sevoflurane combined small dose ketamine group and ketamine group with thirty cases each. Induction time, reovery time and the incidence of compliance in induction, laryngospasm, vomiting, movement, awareness during operation and agitation were recorded. Results The compliance of SK group was better than that of K group,the induction time and recovery time of SK group was shorter than that of K group(P<0.05);the incidence of movement during operation and agitation of SK group was less than that of K group(P<0.05);there was no significant difference in vomiting and awareness between the two groups.Conclusion Anesthesia with sevoflurane combined small dose ketamine is suitable for children during the operation of indirect hernia with quicker onset and recovery and less adverse effect.
