亚剂量氯胺酮静脉麻醉应用儿童斜视矫正术临床观察

Clinical observation of subdose Ketaminum intravenous anthesia for strabotomy in children

氯胺酮镇静镇痛术用于儿童眼病斜视矫正术，２０例使用亚剂量静脉注入与静脉滴入方法，配合局部麻醉，首次静脉注入０．５～０．６ｍｇ／ｋｇ，患儿安静入睡５～６分钟，静脉滴入０．１％氯胺酮０．８～１．５ｍｇ／ｍｉｎ，术中儿童意识消失，维持镇静镇痛Ⅳ级，停药２～３分钟，患儿能唤醒顺利观察眼位。平均麻醉时间２７．３５±１０．９ｍｉｎ，氯胺酮最大用量６０ｍｇ，最小用量２５ｍｇ，术毕全部立即安返病房。结果：此方法减少氯胺酮用量，未发生氯胺酮精神症状和未出现眼心反射等并发症，提高了儿童斜视矫正术的麻醉效果。

Analgesic sedation of Ketaminum was applied for strabotomy in 20 children.Subdose Ketaminum was used in intravenous infusion and intravenous drip,and local ansthesia was applied to cooperation.At first,Ketaminum 0 5～0 6mg/kg was given intravenously.When patient fell asleep for 5～6 minutes,0 1% Ketaminum was given in intravenous drip 0 8～1 5mg/min.During the operation the child was unconscious and was kept in IV grade level of analgesic sedation.After stopping 2～3 minutes of Ketaminum,the patient could be awakened to observe the eye position.Everage anesthsic time was 27 35±10 9min.The largest dose of Ketaminum was 60mg and the smallest dose was 25mg.After operation all patients returned to the ward safely. Result:Ketaminum dose was reduced in this method.There were no complications such as psychical symptom and oculocardiac reflex in ketaminum anesthesia.The anesthesic effect of child strabotomy was increased
