目的 :观察硬膜外低浓度布比卡因复合芬太尼行分娩镇痛的临床效果。方法 :5 0例产妇随机分为镇痛组(E组 )和对照组 (C组 )。E组在宫口开至 3～ 4cm时开始硬膜外注药 ,采用首量 +持续背景量 +PCA(LCP)模式。镇痛药为 0 12 5 %布比卡因 (每毫升含 2 μg芬太尼 )。宫口开至 8～ 9cm时停药。C组按产科常规处理。结果 :硬膜外镇痛对产妇的生命体征无明显影响。E组产妇疼痛感比C组显著良好 (P <0 0 1)。运动不受影响 ,但对宫缩的感觉部分缺失 ,助产率显著高于C组 (P <0 0 5 )。结论 :0 12 5 %布比卡因复合芬太尼用于硬膜外分娩镇痛能取得良好的镇痛效果。
Objective: To observe the clinical effect of epidural bupivacaine combined with fentanyl on labor analgesia. Methods: Fifty mothers were randomly divided into analgesic group (E group) and control group (C group). E group in the cervix to 3 ~ 4cm when the epidural drug injection, the first volume + continuous background + PCA (LCP) mode. Analgesics were 0,125% bupivacaine (2 μg fentanyl per ml). Miyaguchi open to 8 ~ 9cm when withdrawal. C group according to obstetric routine treatment. Results: Epidural analgesia had no significant effect on maternal vital signs. E group pain relief than the C group was significantly better (P <0.01). Exercise is not affected, but the sense of contractions is partially missing, midwifery rate was significantly higher than the C group (P <0 05). Conclusion: 0,125% bupivacaine combined with fentanyl for analgesia in epidural delivery can achieve good analgesic effect.
