小儿脐以下手术应用球后针行腰麻的临床研究

目的:探讨球后针应用于小儿单次腰麻的安全性和可行性。方法:择期行脐以下手术的患儿60例,年龄3～10岁,ASA Ⅰ～Ⅱ级,随机分为A、B两组,各30例。A组以氯胺酮行全凭静脉麻醉;B组用球后针行腰麻,术中均辅以咪达唑仑镇静。记录患儿术中血压、心率、脉搏血氧饱和度、氯胺酮总用量、苏醒时间及不良反应。结果:两组麻醉效果满意,两组患儿血压、心率术中各时点差异有统计学意义(P<0.05),B组苏醒时间较A组短,B组不良反应较A组少。结论:采用球后针进行腰麻,用于小儿脐以下手术麻醉,可取得满意效果。

Objective：To study the safety and feasibility of the retrobulbar needle used in spinal anesthesia of children in Operating under the navel level. Method：Sixty children ,aged 3 -10 years, in operating under the navel level, ASA Ⅰ - Ⅱ, were randomly divided into two groups：group A was intravenous anesthesia used ketamine,group B was single spinal anesthesia used the retrobulbar needle. Both groups were assisted midazolam for sedation. Recording the BP, HR, SpO2 , the quantity of intravenous anesthetics, awaking time and side effects. Result ： It was significantly difference of BP, HR during the operation （P 〈 0.05 ）. The awaking time of group A was longer than group B （P 〈 0. 05）. The side effects of group B was fewer than group A. Conclusion：Using the retrobulbar needle for the single spinal anesthesia of children in operating under the navel level is safety and feasibility.
