妊娠41周后普贝生引产临床观察
摘要 目的: 探讨普贝生用于妊娠≥41周引产 的有效性及安全性。方法: 采用前瞻性分析的的方法,随机选取100例妊娠≥41周初产妇,阴道放置普贝生的可复性装置引产病例作为研究症组;另选100例妊娠≥41周初产妇予以人工破膜加催产素点滴引产自然分娩病例作为对照组,比较两组产妇的临产情况,剖宫产率,新生儿情况。结果: 研究组从给药至临产时间为平均为723.03512.45min,对照组为平均343.18471.53min,两组比较,差异有显著性(P〈0.01)。研究组总产程时间 372.8091.58min,对照组为 491.26173.60 min,差异有显著性(P〈0.01)两组产妇产程中的胎心变化,羊水异常发生率无明显差异;两组新生儿出生时状况无明显差异。结论:普贝生可安全,有效地用于妊娠过期者引产,它可以明显缩短产程,减轻产妇痛苦。

Abstract Objective:To investigate the effectiveness and security for Propess induced labor in patients more than 41 weeks’ gestation.Methods:100 patients entered into the study group with Bishop score 5~7 and vaginal-placed restorable Propess randomly.100 patients entered into control group with Bishop score 5~7 and oxytocin-induced labor after manual ruptured membrane.Labor process, cesarean section rate, and neonate conditions were compared.Results:The periods in study group from Propess use to onset of labor lasted 723.03512.45min while in control group 343.18471.53min with statistic significance (P0.01).Overall labor periods was 372.8091.58min min study group and 491.26173.60 min in control group with with statistic significance (P0.01).Periods for first labor were 287.5788.39min in study group and 428.00166.23min in control group with statistic significance (P0.01).Fetal heart variation and abnormality of amnio fluid made no statistics significance between two groups.There were no statistics significance in fetal Apgar score and birth weight between two groups too.Conclusion: Propess could shorten labor, alleviate pain, and is safe and effective for post-term labor inducement.

1 资料与方法
1.1 随机选择
2006年9月~2007年9月在我院妊娠≥41周(无羊水过少、胎儿窘迫等严重产科合并症)的单胎,头位,无青光眼及哮喘的初产妇100例,年龄在22~34岁,平均年龄为(28.20±3.41)岁。随机选择妊娠≥41周(无无羊水过少、胎儿窘迫等严重产科合并症)的单胎,头位,无青光眼及哮喘的对照病例(人工破膜+缩宫素组)100例,年龄在21~34岁,平均年龄 (27.05±3.30)岁,差异无显著性(P>0.05)。引产前均由专人进行宫颈评分,常规做B超排除胎儿窘迫,羊水过多或羊水过少,胎位不正。引产前均已获得产妇的同意并签同意书。临产后均未行分娩镇痛术。
1.2 引产方法
, 百拇医药
1.2.1 普贝生组
药物由英国CTS公司[Controlled Therapeutics (Scotland)Ltd.]生产,放置前由专人进行宫颈Bishop评分,在无菌操作下,将保留在冰箱中冷冻的普贝生放入阴道后穹隆,产妇卧床30min后,监护胎心及宫缩情况,在临产或破膜后将药取出,否则,在用药12h取出;普贝生放药未临产者,于放药24h行人工破膜+缩宫素引产,观察放药后至临产时间,总产程时间;剖宫产率;产后出血及新生儿情况。
1.2.2 人工破膜+缩宫素组
人工破膜后予5%葡萄糖500ml+缩宫素2.5IU,由8滴/分钟开始,逐渐增加滴数或缩宫素剂量,直至有效宫缩,即30s/3~5min。每日入液量不超过1500ml,用药8小时不临产则拔除点滴待产,第2日未临产者继续缩宫素点滴引产。
1.2.3 统计学方法
, 百拇医药
采用SPSS10.0统计软件。计数资料用卡方检验,计量资料用t检验。
2 结 果
2.1 一般情况
两组初产妇平均年龄,孕次,孕周,宫颈Bishop评分差异无显著性(P>0.05)。
2.2 引产时间
从用药到临产时间,普贝生组:(761.09±574.75 )min;缩宫素组:(351.92±482.82) min,两组比较,(t=2.708,P<0.01,差异有显著性。
两组产程比较见下表
2.3 分娩方式
两组相比,普贝生组剖宫产率(6/100)比缩宫素组(16/100)剖宫产率低,差异具有显著性( X2=27.65, P<0.01)。普贝生组剖宫产中3例胎儿窘迫,4例临产后考虑相对头盆不称行剖宫产;缩宫素组剖宫产中4例胎儿窘迫,3例临产后发热,10例临产后考虑相对头盆不称行剖宫产。两组新生儿Apgar 评分,体重均无明显差异。两组产后出血量:普贝生组产后出血量(274.78±39.41.03)ml,缩宫素组产后出血量(306.92±69.96)ml,差异无显著性( P>0.05)。

2.4 药物副作用
普贝生组2例子宫收缩过频;对照组(缩宫素组)无子宫收缩过频,普贝生组1例发生恶心、呕吐。
2.5 感染
普贝生组无产时宫腔感染及产褥感染,对照组(缩宫素组)2例产时发热,考虑宫内感染剖宫产,2例发生产褥感染。
3 讨 论
普贝生(Propess)为控释性前列腺素E2栓剂,化学成分含地诺前列酮10mg,带有一个不为生物所降解的药物控释装置,控释以每小时0.3mg的速度缓慢释放。外源性的PGE2有松弛宫颈平滑肌利于宫颈扩张,同时也能诱发宫缩,以达引产成功目的[1]。, 百拇医药(刘亚杰)
