目的观察2种不同镇痛模式应用于可行走性分娩镇痛第一产程潜伏期的效果。方法对120例自愿接受可行性分娩镇痛的产妇随机分为2组(n=60):连续硬膜外镇痛组(A组),联合腰麻与硬膜外腔阻滞组(B组)。当产妇宫口开至1~2 cm时,A组在硬膜外穿刺成功后接电子泵,持续输入0.15%罗哌卡因复合芬太尼1μg/ml:首次剂量8 ml,维持量5 ml/h,追加量3 ml/次,间隔15 min。B组腰麻注入0.15%罗哌卡因1.5 mg,硬膜外持续泵入0.15%罗哌卡因复合芬太尼1μg/ml,速度为3 ml/h,追加量2 ml/次,间隔15 min。与未行分娩镇痛组(C组)对照,观察3组产妇镇痛效果、产程时间、产后出血率。结果与C组比较,A、B两组镇痛效果明显,第一产程缩短,应用催产素比例提高(P<0.05)。结论 2种镇痛方法能有效减轻产妇产程中的疼痛,缩短第一产程。
Objective To observe the effects of two different modes of analgesia on the latency of labor-induced labor analgesia in the first stage of labor. Methods One hundred and twenty cases of women receiving voluntary labor analgesia were randomly divided into two groups (n = 60): continuous epidural analgesia group (group A), combined spinal and epidural block group (group B ). When the maternal uterine opening to 1 ~ 2 cm, A group of successful epidural puncture after the electronic pump, continuous infusion of 0.15% ropivacaine combined fentanyl 1μg / ml: the first dose of 8 ml, the maintenance dose of 5 ml / h, the additional amount of 3 ml / time, interval 15 min. In group B, 0.15% ropivacaine 1.5 mg was injected into the spinal cord and 0.15% ropivacaine combined with fentanyl 1 μg / ml was injected into the epidural space at a speed of 3 ml / h with an additional volume of 2 ml / min. And did not make labor analgesia group (C group) control, analgesic effect of the three groups were observed, labor process, postpartum hemorrhage rate. Results Compared with group C, the analgesic effects of group A and group B were obvious. The first stage of labor was shortened and the proportion of oxytocin was increased (P <0.05). Conclusion The two analgesic methods can effectively reduce the pain in the labor process and shorten the first stage of labor.
