阈下剂量氯胺酮麻醉剖宫产对新生儿氧摄取率的影响

目的研究阈下剂量氯胺酮全凭静脉麻醉用于剖宫产手术对新生儿全身氧摄取率的影响。方法 ASAI～II级的剖宫产病人80例,随机分为全凭氯胺酮麻醉组(Ket组)和连续硬膜外麻醉组(EA组)。术中持续监测BP、SpO2、HR并比较两组新生儿娩出后1分钟和5分钟Ap-gar评分,新生儿全身氧摄取率(ERO2)的差异。结果两组新生儿ERO2及Apgar评分均无显著性差异(P>0.05)。结论阈下剂量氯胺酮在新生儿娩出前单独实施全凭静脉麻醉,新生儿氧摄取率及Apgar评分未见明显变化。

Object ive To investigate the effection of a subdissociative—dose ketamine used in total intravenous anesthesia for cesarean section on the neonates＇ERO2..Method Eighty pregnant women undergoing cesarean sections,ASA class I～II,were randomly divided into two groups with forty cases each,one group was ketamine anesthesia（Ket）,and the other group received the continuous epidural anesthesia（EA）.The data of BP,HR,SpO2,Apgar scores,oxygen extration rate（ERO2） were recorded or measured.Results There were no statistically significant differences between the two groups in terms of ERO2 and the neonatel Apgar scores（P0.05）.Conclusion A subdissociative-dose ketamine in total intravenous anesthesia for cesarean section has no effection on the neonates＇ERO2 and the Apgar scores.
