【摘要】 目的 :探讨硬膜外泵注芬太尼与布比卡因用于分娩镇痛的有效性及安全药物剂量。方法 :以 0 15 %布比卡因为对照 ,比较 0 0 0 0 5 %至 0 0 0 12 %范围内四种不同浓度芬太尼与之混合硬膜外泵注的分娩镇痛效果。结果 :选用 0 0 0 0 8%与 0 0 0 1%两种浓度芬太尼与 0 15 %布比卡因混合泵注时 ,镇痛作用起效快 ,镇痛时间明显延长 ,而且不增加副作用。结论 :硬膜外连续泵注芬太尼与布比卡因用于分娩镇痛能明显改善镇痛效果 ,芬太尼使用浓度以限制在0 0 0 0 8%至 0 0 0 1%为宜更多还原

【Abstract】 Objective:To investigate the efficiency and safe drug volumes of fentanyl and bupivacaine for epidural analgesia in labor.Methods:The efficiency of four different concentrations of bupivacaine and fentanyl combination was compared with 0 15% bupivacaine during delivery.Results:0 0008% fentanyl and 0 15% bupivaine or 0 001% fentanyl and 0 15% bupivacaine was faster and longer without side effect.Conclusion:Fentanyl and bupivacaine provide a better pain relief in delivery analgesia.The suitable range of concentration of fentanyl should be from 0 0008% to 0 001%.更多还原
