低剂量布比卡因联合芬太尼腰麻在剖宫产术中的应用

摘要

Objective To observe the efficacy of application of spinal anesthesia with low dosage of bupivacaine combined with fentanyl in caesarean section. Methods Eighty nulliparous women with physical status level 1 according to the classification of American Society of Anesthe-siologists(ASA)were undertaken with caesarean section under spinal anesthesia,and they were randomly allocated in two groups(LBF group and CB group,each with 40 cases). They were received spinal anesthesia with bupivacaine 7. 5 mg combined with fentanyl 25 μg in 0. 9% sodium chloride solution 2ml(group LBF,n = 40)or bupivacaine 10mg in 0. 9% sodium chloride solution 2 ml(group CB,n = 40). The hemodynam-ics,effect of spinal anesthesia,stability of anesthesia and side effects were observed in patients of these two groups. Results The stability of he-modynamics in patients of group LBF was significantly better than that of patients in group CB( P 0.05）。结论低剂量布比卡因（7.5 mg）联合芬太尼（25μg）腰麻是一种用于剖宫产手术中的安全、有效的方法。
