摘要
本文通过对8例连续硬膜外注药分娩镇痛的产妇应用连续宫腔内测压的方法了解硬膜外阻滞分娩镇痛对子宫收缩力的影响。方法:在放置宫腔内测压管后,产妇依次接受硬膜外注入(1)3ml0.125％布比卡因;(2)10ml0.125％布比卡因;和(3)以10ml/h的速度连续输注0.0625％布比卡因/0.2％氯胺酮混合液。宫口开全后停止输注。结果:注入初始量镇痛药后子宫收缩有轻度抑制,持续30min后恢复,连续输注及第二产程中子宫收缩无抑制现象。结论:低浓度局麻药及合并少量氯胺酮进行连续硬膜外输注分娩镇痛虽然对子宫收缩有短时间的轻度抑制,但不会影响产力。第二产程不用药有可能避免第二产程延长。
Uterine contractivity was measured in 8 nulliparous women with continuous epidural analgesia during labor. After vaginal catheter was inserted, each patient received in sequence: (1) 3ml 0. 125%bupivacaine; (2) 10ml 0. 125% bupivacaine; and (3) a continuous epidural infusion of 0. 0625% bupivacaine /O. 2% ketamine at a rate of 10ml/h.The epidural infusion was discontinued in the second stage of labor. Results:As the top-up dose was given, a mild depression of uterine activity, lasting 30 minutes, was noted. There was no depression of uterine activity during the infusion period and the second stage of labor. Conclusion;The mixture of low concentration bupivacaine and ketamine epidurally infused does not result in depression of uterine activity for nulliparous women.
