  • Effect of Different Pre-Labor Positions for Premature Rupture of Membranes with Vertex and Engaged Presentation on the Maternal and Neonatal Outcomes

    Objective To explore the effect of different pre-labor position for premature rupture of membrane (PROM) after 37 weeks with vertex and engaged presentation on the maternal and neonatal outcomes. Methods A total of 120 women over 37 weeks PROM with single fetus in vertex presentation and engaged head were randomly allocated into two groups. The trial group (60 women) received no limit of movement after hospitalization and before labor while the control group (60 women) adapted lateral and supine position alternatively with hip-up. Labor process and neonatal outcomes were observed and recorded. SPSS 13.0 software was adopted to analyze the data. Results Compared with the control group, the trial group had higher rate of normal birth (70% vs. 46.7%, χ2=6.72, P=0.01), shorter first and second stage of labor (t=2.11, P=0.039; t=2.75, P=0.007), fewer incidence of dysuria during labor (χ2=8.11, P=0.0041), and less amount of amniotic fluid (107±55 mL vs. 248±42 mL, t=4.188, P=0.000 1). Conclusion For PROM over 37 weeks pregnancy with single vertex presentation and engaged head, no limit on the position before labor is safe and feasible, and it can improvie spontaneous delivery rate, shorten labor process, decrease amount of amniotic fluid, and eliminate the incidence of dysuria. It is worth to be popularized in the clinic.

Methods: From in January 2005 to December 2006, treated 217 cases of premature rupture of membranes in pregnant women as control group, from January 2007 to December 2008 treated 248 cases of premature rupture of membranes as observation group. The control group used the traditional textbook approach to care. The observation group to determine the correct premature rupture of membranes, fetal assessment, pregnant women to choose the correct prelying, strengthen the preproduction, the postnatal care norms positive measures such as the prevention of infection. Results:The suitable medication and nursing procedure could effectively reduce postpartum hemorrhage, fetal distress, the occurrence of incision infection. Conclusion: The maternal premature rupture of membranes, as soon as possible to take the correct and effective nursing interventions can reduce the incidence of obstetric  complications to protect the health of mothers and infants.

  • Preterm Birth

    截止至2002年5月,现有早产治疗的临床证据如下: (1) 高危早产:在一些国家实施的RCT发现,在降低早产危险方面,加强产前保健与普通产前保健没有明显差异.包括5个RCT的1个系统评价发现,对有宫颈改变的妇女行宫颈环扎术有不同的结果,没有明确的结论.1个大样本的RCT发现,孕9~29周宫颈功能可能不全的妇女进行预防性宫颈环扎手术与不环扎相比,能明显降低早产(<33孕周),但也会明显增加产褥感染的危险.另外4篇较小样本的RCT发现,孕10~30周、具各种早产高危因素的妇女,进行预防性宫颈环扎手术与不环扎相比,并不能降低早产(<34孕周).1篇系统评价的2个RCT报告,对有宫颈改变的妇女进行环扎术有不同的结果,其中1个RCT发现其并不能明显降低早产(<34孕周),而另外1个较小样本的RCT却发现宫颈环扎手术加卧床休息与单纯卧床休息比较,能明显降低34周前的早产.没有1个RCT证实行环扎术加卧床休息与单纯卧床休息相比,能降低围生儿死亡率. (2) 胎膜早破:1个系统评价发现,对胎膜早破的妇女,抗生素较安慰剂能明显延长孕周、降低新生儿发病率的危险,如新生儿感染、出生后氧疗、脑部超声异常等.阿莫西林加克拉维酸治疗与新生儿坏死性小肠结肠炎的发生率明显增加有关.一个基于1个RCT的系统评价发现,没有充足的证据证实羊膜腔灌注与不灌注比较能改善胎膜早破后的新生儿结局. (3) 先兆早产的治疗:①β-肾上腺素兴奋剂:1个系统评价发现,β-肾上腺素兴奋剂与安慰剂或不治疗相比,并不能明显降低围生儿死亡率、呼吸窘迫综合征及低体重儿(<2 500 g)发生率,且与与安慰剂或不治疗相比,β-肾上腺素兴奋剂增加孕母副反应,如胸痛、心悸、呼吸困难、震颤、恶心、呕吐、头痛、高血糖、低钾血症.②钙离子通道拮抗剂: 没有关于钙离子通道拮抗剂与安慰剂比较的系统评价或RCT.1个系统评价发现,钙离子通道抑制剂与其它保胎药(主要是β-肾上腺受体兴奋剂)比较,能显著降低48 h内的早产分娩,减少因孕母副反应退出治疗和新生儿发病率.③硫酸镁:1个系统评价发现,硫酸镁与安慰剂比较,并不能明显降低孕36周前的早产率、围生儿死亡率、呼吸窘迫综合征的发生率.另一个系统评价发现,硫酸镁和其他宫缩抑制剂(β-肾上腺素兴奋剂、钙离子通道拮抗剂、前列腺素合成抑制剂、硝化甘油、酒精和葡萄糖注射剂)比较,并不能明显降低48 h内早产率(尽管结果没有差异).④垂体受体拮抗剂(阿托西班):1个系统评价纳入 2个RCT,对阿托西班和安慰剂治疗早产进行比较有不同的结果.较大样本的RCT发现,阿托西班较安慰剂能延长孕周,但阿托西班增加了孕28周以下的胎儿死亡率.另一个RCT发现,阿托西班增加了48 h内的早产.⑤前列腺素抑制剂(消炎痛):1个系统评价发现,消炎痛与安慰剂比较,能明显降低孕37周前的48 h和7天的早产率的证据有限.然而,同时发现消炎痛与安慰剂或不治疗相比,并不能明显降低围生儿死亡率、新生儿呼吸窘迫综合征、肺支气管发育不良、坏死性小肠结肠炎、新生儿败血症或低体重儿.但这个系统评价样本太小,尚不能发现有临床意义的差异. (4) 择期或非择期剖宫产对早产妇女治疗效果:1个系统评价结果发现,择期剖宫产较非择期剖宫产会增加孕母的发病率,却不能降低新生儿的发病率和死亡率.但尚不能证明此效果是否对新生儿有临床意义. (5) 改善早产妊娠结局的干预措施:①对早产者采用皮质类固醇:1个系统评价认为,对可能发生早产的妇女使用皮质激素较安慰剂或不处理能明显降低早产儿出生后呼吸窘迫综合征、新生儿死亡率和颅内出血的发生.②促甲状腺激素释放激素在早产中的运用:1个系统评价发现,在早产的高危妇女中,促甲状腺激素释放激素和类固醇激素联合应用与单用皮质类固醇激素比较,对新生儿结局的影响无明显差异,但会明显增加孕母和胎儿的不良反应.③抗生素:1个系统评价发现,抗生素与安慰剂比较,不能延长孕周、降低新生儿死亡率,但可降低孕母感染率.

  • Risk factors for full-term prelabor rupture of membranes: a prospective nested case-control study

    Objective To investigate the incidence of full-term prelabor rupture of membranes (FPROM) and risk factors for FPROM. Methods A prospective nested case-control study was performed on pregnant women in early pregnancy and their spouses, who underwent prenatal examination for the first time in Zhuhai Center for Maternal and Child Health Care from May 2021 to December 2022. Pregnant women with a clear diagnosis of FPROM were included in the case group, and pregnant women without FPROM were randomly selected at a 1∶3 ratio for inclusion in the control group. A questionnaire survey was performed to collect exposure information possibly related to FPROM. The hospital's medical record system was used for information verification and to record the pregnancy outcomes. A multivariate logistic regression analysis was used to investigate the risk factors for FPROM. Results The incidence of FPROM in this study was 24.27%. The multivariate logistic regression analysis showed that obesity pregnant women, smoking, drinking, unbalanced diet, high-intensity physical activity during pregnancy, eating areca nut before pregnancy, using glucocorticoids during pregnancy, older at the time of first pregnancy, a history of adverse pregnancy outcomes, a history of pregnancy complications, a history of diabetes, a history of scar uterus, no folate supplementation during pregnancy, repeated intrauterine operations, polyembryony, polyhydramnios, transverse fetus and fetal cephalopelvic disproportion as the way of conception were risk factors for FPROM (P<0.05). Additionally, the pregnant women whose spouses were obese or smoked or drinking had an increased risk of FPROM (P<0.05). Lower gravidity and lower parity were protective factors against FPROM (P<0.05). Conclusion There are many risk factors for FPROM. Special attention should be given to the life behaviors of pregnant women during pregnancy, and health education should be strengthened for pregnant women and their spouses to help them develop good living habits and reduce the incidence of FPROM.
