目的:比较静注氯胺酮与吸入七氟醚麻醉在小儿疝气手术中的麻醉效果。方法:随机分为氯胺酮组和氯胺酮复合七氟醚组,每组各40例。氯胺酮氯胺酮2mg/kg,术中根据需要追加首剂的1/3;七氟醚组入室在家人陪同下给予氯胺酮0.5mg/kg待小儿入睡后面罩吸入6%～8%的七氟醚,氧流量4L/分。观察两组麻醉效果术中SPO2,HR,术后角膜反射时间,定向力恢复时间,恶心呕吐发生率及手术时间。结果:与氯胺酮组相比,七氟醚组SPO2>90%无差别,HR增快不明显,角膜反射,定向力恢复时间及手术时间均缩短。结论:七氟醚对呼吸道的刺激小,具有诱导快、苏醒迅速、后遗症少,能有效抑制手术应激反应等特点。
OBJECTIVE: To compare the anesthetic effects of intravenous ketamine and inhaled sevoflurane anesthesia in pediatric hernia surgery. Methods: Randomly divided into ketamine group and ketamine combined sevoflurane group, 40 cases in each group. Ketamine Ketamine 2mg / kg, additional 1/3 of the first dose as needed; sevoflurane group room accompanied by family Ketamine 0.5mg / kg to be asleep in children after the mask inhalation of 6% to 8% sevoflurane, oxygen Flow 4L / min. The anesthetic effect of the two groups were observed SPO2, HR, postoperative corneal reflex time, recovery time of orientation force, incidence of nausea and vomiting and operation time. Results: Compared with the ketamine group, the SPO2> 90% of the sevoflurane group did not show any significant difference, HR increased rapidly, and the corneal reflex, the recovery time of the directional force and the operation time were shortened. CONCLUSIONS: Sevoflurane is less irritating to the respiratory tract and has the characteristics of rapid induction, rapid recovery, fewer sequelae, and effective suppression of surgical stress response.
