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
Objective: To investigate the effectiveness and safety of epidural pump fentanyl and bupivacaine in labor analgesia. Methods: 0 15% bupivacaine was used as a control to compare the labor analgesic effect of epidural pump with four different concentrations of fentanyl in combination with epidural pump in the range of 0 0 0 0 5% to 0 0 0 12%. Results: The analgesic effect was rapid and the analgesic time was significantly prolonged without any increase of the analgesic effect when using the mixed pump of 0 0 0 8% and 0 0 0 1% of two concentrations of fentanyl and 0 15% bupivacaine side effect. CONCLUSIONS: Epidural continuous infusion of fentanyl and bupivacaine for labor analgesia can significantly improve the analgesic efficacy. The concentration of fentanyl used is limited to 0 0 0 0 0% to 0 0 0 1%
