新生儿肥厚性幽门环肌切开术的麻醉安全性

目的 :探讨新生儿先天性肥厚性幽门环肌切开术的麻醉安全性。方法 :肥厚性幽门环肌切开术新生儿 2 0例分两组 ,每组 10例。A组 :在浅基础麻醉下行骶管阻滞 (0 .2 %布比卡因 2 mg/ kg) ;B组 :氯胺酮和 r- OH静脉复合全麻。对两组患儿术中的 SPO2 、RR、HR变化及麻醉效果、围术期并发症作比较。结果 :术中 SPO2 、RR A组变化不大 ,但 B组变化幅度较大 ,两组比较统计学有显著性意义 (P<0 .0 1) ;A组围术期分泌物增多、呕吐、误吸等并发症明显少于 B组。结论 :浅基础麻醉下骶管阻滞是新生儿先天性肥厚性幽门环肌切开术安全可靠的麻醉方法 ,有效预防围术期并发症。

Optimal Anesthetic Method during Hypertrophic Pyloric Circular Muscle Section in Neonate

Objective:To explore an optimal anesthetic method during hypertrophic pyloric circular muscle resection in neonate.Methods:20 neonates scheduled for hypertrophic pyloric circular muscle resection were randomly divided into two groups. Neonates in group A(n=10) underwent caudal block (0.2% bupivacaine 2 mg/kg)combined with basal anesthesia. Neonates in group B(n=10) received ketamine and r-OH. SPO 2,RR,HR,anesthetic effect and complication during anesthesia were monitored and recorded in two groups and the effects of sedation were observed in two groups.Results:Compared with preoperation,SPO 2 and RR kept unchanged in group A ,but remarkably reduced in group B during operation. There was significant difference in SPO 2 and RR between two groups during operation(P<0.01).The complication such as excessive secretion,vomit and aspiration of vomit were less in group A than those in group B.Conclusion:Caudal block combined with basal anesthesia was a reliable anesthetic method during hypertrophic pyloric circular muscle resection,which could prevent anesthetic complication effectually.
