妊高征剖腹产腰-硬联合麻醉效果观察

Effect of Combined Spinal-epidural Anesthesia in Caesarean Section of Pregnancy-induced Hypertention

目的 观察腰麻-硬膜外联合麻醉(CSEA)用于妊高征剖腹产术的可行性。方法 将 40 例妊高征拟行剖腹产手术的患者,随机分为CSEA组和EA组,每组20例。分别于椎管内注药后记录痛觉阻滞平面达T8 水平的时间、评定麻醉效果、并记录注射局麻药至胎儿娩出的时间(I-DI)及新生儿娩出1min和5min的Ap gar评分。结果 两组术中SP、DP、HR和SpO2 的变化及新生儿娩出1min和5min的Apgar评分差异无显著性(P>0.05)。与EA组比较, CSEA组的麻醉起效时间和 I-DI明显缩短(P<0.05)。结论 CSEA用于妊高征剖腹产有用药量小,麻醉起效快,效果更确切之优点,对母婴无不良影响。

Objective To observe the availability of combimed spinal epidural anesthesia(CSEA) used in pregnancy-induced hypertension (PIH) caesarean section.Methods 40 PIH patients for caesarean section were randomized into epidural anesthesia group (EA,n=20 ) and combined epinal-epidural anesthesia(CSEA,n=20). After local anesthetic given to record the time of reaching the level of T_8 block , to assess the effect of each anesthesia to record the duration between the induction of spinal or epidural block and delivery (I-DI)and Apgar score of the neonate at 1 and 5 min after birth . Results In two groups , the change of SP、DP, HR , SpO_2 and Apgar scores of the neonates at 1 and 5 min after birth has no obvious difference(P>0.05). In comparing with EA, CSEA group effecting time and I-DI shorter obviously(P<0.05). Conclusion CSEA for PIH caesarean section has no adverse effects on maternal and neonates.
