摘　　要：目的　通过对比 ,选择较为科学、有效的评价硬膜外麻醉的手段。方法　 1～ 3岁ASAⅠ～Ⅱ级小儿下腹、下肢、足手术 6 0例 ,先肌注氯胺酮 5mg/kg ,再行硬膜外麻醉 ,给 0 .8～ 1.2 %利多卡因 (含肾上腺素 5ug/ml) 4ml试验量 ,5min排除腰麻 ,追加量 ,使首次量达 8mg/kg。 15min后 ,用反射消失法和针刺法测定阻滞平面。 结果　反射法均能较准确测定出相应阻滞平面 ,而针刺法仅 1/ 3(2 0 / 6 0 )病人测出 (P <0 .0 1) ,而且此 2 0例病人针刺法比反射消失法推出的阻滞平面略高 (P >0 .0 5 )。结论　氯胺酮基础麻醉后进行硬膜外麻醉时 。Objective To assess the blocking levels of epidural anesthesia by measuring vanishment of reflection. Methods 60 ASAⅠ～Ⅱ infants aged 1～3 years undergoing operation on lower abdomen, lower limbs and feet have heen performed epidural anesthesia (EA) using 0.8%～1.2% Lidocaine (including 5ug/ml adrenaline) after ketamine IM.15 minutes after EA, measuring blocking levels by vanishment of reflection or acupuncture way.Results The blocking levels could be measured accurately in all infants by vanishment of reflection and in 20 cases by acupuncture way (P<0.01). In 20 infants, blocking levels was similar between the two means ((P>0.05). Conclusion The epidural blocking levels can be determined by venishment of reflection in infants with ketamine anesthesia.
