摘要
目的分析单胎超重产妇产程特点以及围产期结局。方法以2003年"中国肥胖问题工作组"提出针对我们国家的BMI标准,18.5≤BMI<23.9为正常体重,24.0≤BMI<27.9为超重,BMI≥28.0为肥胖,将孕前超重24.0≤BMI<27.9的310例妊娠晚期(28-42周)单胎妊娠初产妇作为研究对象,另选同期650例孕前正常体重18.5≤BMI<23.9的产妇为对照组。比较两组患者一般资料、活跃期起点、活跃期时限、宫口扩张速度、产程时间、分娩结局等计量资料进行统计学分析。结果两组产妇分娩孕周、孕前体重、孕期体重增长、产检次数、孕期运动、新生儿体重、产后42天体重滞留差异均有统计学意义;对照组产妇第一产程时间长于研究组;各组产妇活跃期起点分布、观察组/对照组3cm 98例(31.6%)/395例(60.8%),4cm 90例(29.0%)/118例(18.2%),5cm 83例(26.8%)/68例(10.4%),≥6cm 28例(9.1%)/31例(4.8%);研究组产妇临产后宫口每进展1cm所需时间中位数高于对照组产妇。6cm之前对照组1cm进展时间较研究组更短(P<0.05),差异有统计学意义。地诺前列酮栓与球囊引产,研究组产妇引产有效率低于对照组,差异有统计学意义(P>0.05)。结论随着BMI的增加,超重产妇会发生延期妊娠,引产宫颈成熟有效率低,通常于4-6cm进入活跃期,超重影响了第一产程时间,但对第二产程无影响,对于超重产妇孕期产前检查时即应该引起足够重视,分娩时更需要有足够的耐心应对产程。
Objective To analyze the characteristics of maternal overweight on the course of labor and perinatal out-come.Methods Pre-pregnancy BMI was categorized into 4 groups using WGOC 2003 standard(<18.5 kg/m^2,18.5-23.9 kg/m^2.24.0-27.9 kg/m^2 and 28.0 kg/m^2)which were defined as underweight,normal weight,overweight and o-besity.310 pregnant women with overweight before pregnancy were randomly selected into the observation group.and.another 650 pregnant women with normal weight before pregnancy were selected into the control group during the same period.The following items were retrospectively analyzed and compared,pregnancy-related indexes.onset of active phrase of labor were ollected.to analyze the efct of individual differences between two groups were statistically ana-lyzed by independent samples t test or chi-square test.Results There were statistically significant differences between.the two groups in gestational weeks,pre pregnancy weight,gestational weight gain,antenatal examination times,gesta-tional exercise.neonatal weight and 42 days postpartum weight retention.The first stage of labor was longer in control group than in observation group.The distribution of the initial phase of the delivery of active overweight women:3 cm control group 395 cases(60.8%)/observation group 98 cases(31.6%),4 cm control group 118 cases(18.2%)/ob-servation group 90 cases(29.0%).5 cm control group 68 cases(10.4%)/observation group 83 cases(26.8%),and≥6 cm control group 31cases(4.8%)/observation group 28 cases(9.1%).The median time for each 1 cm of progression in control group was higher than that in the observation group.Before 6 cm,the 1 cm progression time of the control group was shorter than that of the observation group(P<0.05).The effective rale of induction of labor by dinopros-tone and double-balloon in control group was lower than that of the observation group,and the difference was statisti-cally significant(P>0.05).Postpartum hemorrhage.urine retention and vaginal midwifery rate are higher than that of normal weight
