摘要
目的回顾性总结751例不同年龄组小儿简易骶管麻醉(PCA)之成功率、并发症及量效关系。方法在基础麻醉下,三种不同浓度的利多卡因和/或罗哌卡因,分别0.75～1.25ml/kg(含肾上腺素1:200,000)容积注入骶管腔内。结果成功率为97%,起效时间和阻滞范围分别与局麻药性质、容积相关。然而相同的公斤体重容积在不同的个体中其阻滞范围存在差异,无一例发生局麻药中毒,10例存在呼吸抑制,其余SpO2维持在98%±1%,术中亦无明显的血流动力学改变。结论基础麻醉下行简易骶管麻醉是操作简单,较为安全,成功率较高,并发症较少的脐以下手术的小儿麻醉方法。
Objective The success rate and adverse effects and the relationship between volume and effects of pediatric caudal anesthesia were reported in a retrospective study of 751 pediatric cases. Methods The block was performed under basic anesthesia ,solution of lidocaine and/or ropivacaine （with 1：200, 000epinephrine ）were injected in volumes ranged from 0.75 to 1.25ml/kg. Results The success rate 97%,but in the children over 7years was 89%. The anesthetic onset time and extent analgesia level were positively correlated with the characteristics of the local anesthetics and the volume injected .However, the final extent of sensory blockade varied widely from on patient to anther with the same body weight -related volume. There was not a case had local anesthetic toxicity. Ten cases appeared respiratory depression. The SpO2 remained 98± 1% and there was no significant hemo-dynamic changes. Conclusions The simple caudal anesthesia was safer, success rate was more and adverse effects was less. Operation was simple ,and it was a pediatric anesthesia method of operating under the navel level.
