中文摘要：

目的：对乐蓓尔分娩镇痛仪用于临床分娩镇痛的效果进行观察。方法选择在佛山市南海区第四人民医院产科分娩的足月妊娠初产妇92例，采用随机数字表法分为镇痛仪组和硬膜外镇痛组各46例，镇痛仪组采用乐蓓尔分娩镇痛仪进行镇痛，硬膜外镇痛组采用硬膜外持续镇痛，观察两组产妇的镇痛效果差异及分娩结局。结果镇痛仪组的第一产程、第二产程、总产程均显著低于硬膜外镇痛组（t值分别为3．739、2．634、4．303，均P＜0．05）。镇痛仪组的轻度疼痛率（84．78％）高于硬膜外镇痛组（65．22％），中度疼痛率（15．22％）低于硬膜外镇痛组（34．78％），镇痛仪组的镇痛效果优于硬膜外镇痛组（χ2＝4．696，P＜0．05）。镇痛仪组的1、5、10min Apgar评分与硬膜外镇痛组比较差异均无统计学意义（均P＞0．05）。镇痛仪组的产后出血量显著低于硬膜外镇痛组（ t＝11．770，P＜0．05）。结论乐蓓尔分娩镇痛仪用于临床分娩镇痛较硬膜外持续镇痛具有缩短产程、减少产后出血量、减轻分娩疼痛的优势，同时不会影响新生儿及产妇的分娩方式。

英文摘要：

Objective To observe the effect of Le Beier analgesia apparatus on analgesia in delivery .Methods In Fourth People’s Hospital of Nanhai District 92 full-term primiparas were randomly divided into analgesia apparatus group and epidural analgesia group with 46 cases in each group according to random number table method .Le Beier analgesia apparatus was used in delivery for analgesia apparatus group , while epidural analgesia group received continuous epidural analgesia .Differences in analgesic effect and delivery outcomes of two groups were observed.Results The first stage, second stage and total labor were significantly shorter in analgesia apparatus group than in epidural analgesia group （t value was 3.739, 2.634 and 4.303, respectively, all P 〈0.05）.In analgesic apparatus group mild pain rate （84.78%） was higher than that in epidural analgesia group （65.22%）, while moderate pain rate （15.22%） was lower than in epidural analgesia group （34.78%）.The analgesia effect of analgesia apparatus group was superior to epidural analgesia group （χ2 =4.696,P〈0.05）.The differences in 1, 5 and 10min Apgar score were not significant between analgesic apparatus group and epidural analgesia group （all P〉0.05）.The amount of postpartum hemorrhage in analgesic apparatus group was significantly less than in epidural analgesia group （t=11.770,P 〈0.05）.Conclusion For clinical analgesia, Le Beier analgesia apparatus has the advantages of shortening production process, reducing the amount of postpartum hemorrhage and relieving labor pain , and it does not affect mode of delivery .
