等比重布比卡因腰硬联合麻醉在剖宫产术中的应用

目的探讨0.5%等比重布比卡因腰硬联合麻醉在剖宫产手术中的麻醉效果及安全性。方法选择60例剖宫产手术患者,ASAⅠ~Ⅱ级,随机分为等比重组和重比重组,每组30例,观察各组麻醉起效时间、阻滞平面、达峰时间、麻醉效果、血压变化和不良反应。结果两组患者麻醉效果满意,在给药后5min,重比重组患者的SBP、DBP低于等比重组(P<0.05),等比重组感觉阻滞达峰时间长于重比重组(P<0.05),下肢运动恢复时间短于重比重组(P<0.05),等比重组患者低血压和恶心呕吐发生率低于重比重组(P<0.05)。结论 0.5%等比重布比卡因腰硬联合麻醉较重比重布比卡因更适用于剖宫产手术。

Application of Isobaric Bupivacaine Combined with Spinal and Epidural Anesthesia in Cesarean Section Operation

Objective To evaluate the clinical efficacy and safety of the isobaric bupivacaine combined with spinal and epidural anesthesia for cesarean section operation compared with hyperbaric bupivacaine.Methods Sixty cesarean section operation patients with ASA I ~ Ⅱwere randomly divided into isobaric group and hyperbaric group with 30 patients each.The onset time,sensory block level,quality of anaIgesia were assessed,and the changes of bIood pressure and side effects were recorded.Results The anesthesia of all cases were satisfactory.Systolic and diastolic blood pressures at postanesthetic 5th minute in hyperbaric were lower than in isobaric group (P <0.05).Isobaric group presented a longer onset time than hyperbaric group (P <0.05),but the analgesia and movement recovery time was shorter (P <0.05).Hypotension,nausea,vomiting incidence rates in isobaric group were lower than in hyperbaric group (P <0.05).Conclusion Isobaric bupivacaine combined with spinal and epidural anesthesia is an effective and safe method for cesarean section operation.
