左旋布比卡因腰麻在剖宫产术中的临床应用

目的比较0．5％等比重左旋布比卡因与布比卡因腰麻用于剖宫产手术的麻醉效果。方法选择ASAI～Ⅱ级，拟在腰麻下行剖宫产手术病人60例，随机分为两组，即左旋布比卡因组（LB组）和布比卡因组（B组）.所有病人分别蛛网膜下腔注射0．5％等比重左旋布比卡因与布比卡因2ml，记录各组感觉和运动神经阻滞的起效时间和维持时间、新生儿1min和5min Apgar评分和麻醉并发症。结果LB组病人的感觉阻滞起效时间（14．1±1．6）min，要晚于B组（8．9±2．7）min（P〈0．05），术中运动阻滞级别、新生儿LApgar评分以及术后感觉和运动消退时间两组比较差异无显著性（P〉0．05）。结论0．5％等比重左旋布比卡因腰麻用于剖宫产手术是安全有效的，并能达到较为完善的麻醉效果。

Spinal anesthesia with levobupivacaine in caesarean section

Objective To compare the anesthetic effect of 0.5% isobaric levobupivacaine versus levobupivacaine in cesarean section. Methods 60 ASA Ⅰ - Ⅱ patient undergoing caesarean section under spinal anesthesia were randomly assigned to receive injections of 0.5% isobaric levobupivacaine (LB group) or bupivacaine of 2ml (B group) into the subarachnoid space Time to onset and to maintenance for sensory and motor nerve blockade, 1 min- and 5 min- Apgar's scores for neonates, and complications of the anesthetics were noted. Results The time to onset for sensory blockade was delayed in LB group LB as compared with B group (14.1 ± 1.6) min vs. (8.9 ± 2.7) min, P< 0.05]. There were no significances between the two groups in the degree of motor blockade, Apgar's scores, and postoperative time to disappearance of sensory and motor blockade (P> 0.05). Conclusions Spinal anesthesia with 0.5% isobaric levobupivacaine in caesarean section is safe and effective and achieves an ideal anesthetic effect.
