利多卡因和丁卡因混合液硬膜外麻醉用于剖宫产术

EPIDURAL ANESTHESIA IN CAESAREAN SECTION BY USING MIXED FLUID OF LIDOCAINE AND TETRACAINE

130例剖宫产术均采用1.6％利多卡因与0.14％丁卡因(内含1:20万u肾上腺素)混合液作连续硬膜外麻醉。利多卡因用量180～240mg,平均3.05～3.34mg/kg,丁卡因用量15.8～20.9mg,平均0.21～0.28mg/kg,本组麻药首剂量为10～12ml,15～20分钟即可达到麻醉的目的。均不用术前药。在胎儿取出前,对产妇一律未用强化麻醉药及全麻药,输液以平衡液为主,限制葡萄糖液输注,以免新生儿产生高血糖症。避免新生儿出生前受到药物的影响。
