目的 观察联合腰麻硬膜外麻醉 (CSEA)不同剂量布比卡因腰麻用于剖宫产手术的效果及对母婴的影响。方法 2 0 0 2年 1月至 2 0 0 3年 6月将ASAⅠ级 ,择期剖宫产产妇 15 0例 ,随机分成 3组 ,每组 5 0例 ,麻醉方法为CSEA ,腰麻分别给予等容量、近似相对密度布比卡因 :A组 10 0mg、B组 7 5mg、C组 6 0mg ,观察其麻醉效果。结果 A、B两组麻醉效果相近 ,但A组低血压发生率高 (P <0 0 1) ,运动恢复慢 (P <0 0 0 1) ,C组麻醉效果不佳。各组新生儿Apgar评分均在 7分以上 ,无头痛等并发症发生。 结论 CSEA用于剖宫产手术 ,0 375 %布比卡因 2mL(7 5mg)腰麻 ,起效快 ,效果确切 ,术后恢复快 ,并发症少 ,对新生儿无明显影响 ,可供临床选用。
Objective To observe the effects of spinal cord anesthesia (CSEA) with different doses of bupivacaine for spinal cesarean section on cesarean section and its effects on mothers and infants. Methods From January 2002 to June 2003, 150 ASA class Ⅰ, elective cesarean section women were randomly divided into 3 groups (n = 50). The anesthesia was performed by CSEA and the spinal anesthesia was given respectively Volume, approximate relative density of bupivacaine: A group of 10 0mg, B group 7 5mg, C group 60mg, observe the anesthetic effect. Results The anesthetic effects in groups A and B were similar, but the incidence of hypotension in group A was higher (P <0.01), and the recovery was slower (P <0.01). The anesthesia in group C was not effective. Apgar scores of neonates in each group were more than 7 points, no headache and other complications. Conclusions CSEA is used for cesarean section and 0 375% bupivacaine 2mL (7 5mg) spinal anesthesia has rapid onset and definite effect, rapid recovery after operation, few complications and no effect on newborn Use.
