目的比较喉罩下七氟醚吸入麻醉与氯胺酮静脉麻醉在小儿腹股沟斜疝手术中的麻醉效果。方法择期行腹股沟斜疝修补术手的患儿60例,年龄3～9岁,ASAⅠ～Ⅱ级,随机均分为喉罩下七氟醚麻醉组(S组)和氯胺酮麻醉组(K组)。S组给予七氟醚吸入诱导,置入喉罩成功后保留患儿自主呼吸,术中根据手术刺激大小调整七氟醚浓度为3%～4%;K组患儿诱导时静脉注射氯胺酮1mg/kg,术中间断静脉追加氯胺酮0.5～1.0mg/kg维持麻醉。记录麻醉前(T0)、切皮前(T1)、切皮后1min(T2)、30min(T3)、术毕时(T4)MAP与HR;记录两组患儿意识消失、苏醒、清醒时间;观察两组患儿麻醉期间及麻醉后不良反应情况。结果两组术中镇静、镇痛效果良好,差异无统计学意义(P>0.05);与K组比较,S组麻醉诱导后及术中血流动力学变化小,意识消失、苏醒、清醒时间短,麻醉期间及麻醉后不良反应发生率低(P<0.05)。结论喉罩下七氟醚吸入麻醉在小儿腹股沟斜疝手术中优于氯胺酮静脉麻醉。
Objective To compare the anesthetic effects of anesthesia with sevoflurane and ketamine intravenous anesthesia in children undergoing inguinal indirect hernia surgery. Methods Sixty children (aged 3-9 years old, ASA Ⅰ ~ Ⅱ) undergoing inguinal hernia repair were randomly divided into two groups: sedation group (group S) and ketamine anesthesia group (group K) . S group were given sevoflurane induction, laryngeal mask after the successful placement of children with spontaneous breathing, intraoperative resuscitation according to the size of the adjustment sevoflurane concentration of 3% to 4%; K group induction of ketamine at the induction of 1mg / kg, intraoperative intermittent intravenous ketamine added 0.5 ~ 1.0mg / kg to maintain anesthesia. The MAP and HR before anesthesia (T0), before skin incision (T1), 1min after skin incision (T2), 30min (T3), and at the end of surgery were recorded. The consciousness, consciousness and awake time of the two groups were recorded; The adverse reactions of the two groups were observed during anesthesia and anesthesia. Results The intraoperative sedation and analgesic effect were good in both groups, with no significant difference (P> 0.05). Compared with K group, the change of hemodynamics was less and the consciousness disappeared, awake, awake time Short, narcotic and narcotic adverse reaction rate was low (P <0.05). Conclusion The laryngeal mask sevoflurane inhalation anesthesia in children with inguinal hernia surgery is better than ketamine intravenous anesthesia.
