Furthermore,excessive volumes of intravenous fluids may pose risks to both the mother and her newborn and different fluids are associated with different risks.;Objectives To evaluate whether the routinead ministration of intravenous fluids to low-risk nulliparous labouring women reduces the duration of labour and to evaluate the safety of intravenous fluids on maternal and neonatal health.;Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trils Register(13February2013。;Selection criteria Randomised controlled trials of intravenous fluid administration to spontaneously labouring low- risk nulliparous women. ? 选择标准 ? 低危初产妇进行静脉输液管理的随机对照试验。;Data collection and analysisi The review authors independtly assessed trials for inclusion,trial quality and extracted data. ? 数据收集和分析 作者对纳入标准、试验质量和提取的数据进行独立评估。;Main results We included nine randomised trials with 1781 women.Three trials had more than two treatment arms and were included in more than one comparison. ? 主要结果 ? 我们纳入9个随机试验，其中包含1781名孕妇。三个试验包括两种以 上治疗和进行一个指标以上的比较。;Two trials compared women randomised to receive up to 250mL/hour of Ringer’s lactate solution as well as oral intake versus oral intake only. For women delivering vaginally, there was a reduction in the duration of labour in the Ringer’s lactate group(mean diference (MD)- 28.86minutes,95%confidence interval(CI)-47.41to-10.
