目的探讨孕期体重管理对初产妇产程及母婴结局的影响,为控制孕期体重过度增加,缩短产程,减少母婴不良结局提供理论依据。方法收集2016年10月-2017年1月在该院建卡的孕前体质量指数(BMI)≥24 kg/m2的初产妇100例作为研究对象,按照随机数字表法分为对照组(50例)和观察组(50例)。对照组孕妇接受常规产检,观察组孕妇在常规产检基础上进行体重管理,持续至分娩前。对比两组孕妇分娩前BMI值,分娩产程及母婴不良结局的差异。结果干预后,观察组孕妇分娩前BMI值低于对照组(P<0.05),分娩总产程、第一产程、第二产程时间短于对照组(P<0.05),巨大儿、胎儿宫内窘迫、新生儿窒息等围产儿不良结局,胎膜早破、产程阻滞、产后大出血等母体不良结局发生率均低于对照组(均P<0.05)。结论孕期体重管理可有效抑制孕妇BMI值的过度增加,缩短初产妇产程并优化母婴结局。 Objective To explore the effect of pregnancy weight management on the labor process and maternal and infant outcomes in primipara and provide a theoretical basis for controlling overweight during pregnancy, shortening labor and reducing maternal and infant adverse outcomes. Methods A total of 100 primiparages with a pre-pregnancy body mass index (BMI) ≥24 kg / m2 were enrolled in this hospital from October 2016 to January 2017. The patients were divided into control group (50 cases ) And observation group (50 cases). The pregnant women in the control group underwent routine birth control, and the pregnant women in the observation group underwent weight management on the basis of routine birth examination until the time of delivery. The differences of BMI before delivery, labor during labor and maternal and infant adverse outcomes between the two groups were compared. Results After intervention, the BMI of the pregnant women in the observation group before delivery was lower than that of the control group (P <0.05), and the time of delivery, the first stage of labor and the second stage of labor were shorter in the observation group than in the control group (P <0.05) , Neonatal asphyxia and other perinatal unfavorable outcomes, premature rupture of membranes, birth process block, postpartum hemorrhage and other maternal adverse outcomes were lower than the control group (P <0.05). Conclusion Pregnancy weight management can effectively inhibit the excessive increase of BMI in pregnant women, shorten the birth process and optimize the maternal and infant outcomes.
