目的:评估前置胎盘对胎儿出生体重的影响。方法:选取2010年5月～2011年8月间因前置胎盘于嘉兴市妇幼保健院住院分娩的68例患者为研究对象,依分娩孕周不同,依次分为孕28周+0天～31周+6天(A组)、孕32周+0天～33周+6天(B组)、孕34周+0天～36周+6天(C组)、孕37周+0天～40周+0天(D组)及孕40周+1天～41周+0天(E组)为实验组;同时取同时期同孕周单纯早产及足月妊娠的患者为对照组,按不同前置胎盘类型分类,比较相对应孕周出生时新生儿体重。结果:孕37周前新生儿体重与单纯早产组比较无统计学差异;孕37周～40周组新生儿体重与足月妊娠组相比无统计学差异;孕40周后前置胎盘新生儿体重较正常足月妊娠组偏高,且在前置胎盘合并胎盘植入患者中明显增高。结论:孕40周前前置胎盘对胎儿生长无影响,而孕40周后胎儿生长体重增高患者需警惕胎盘植入。
Objective: To evaluate the impact of placenta previa on birth weight. Methods: From May 2010 to August 2011, 68 patients with prepartal placenta inpatient delivery in Jiaxing MCH hospital were selected as study subjects. According to different gestational weeks of delivery, they were divided into 28 weeks pregnant +0 days ~ 31 Weeks +6 days (group A), 32 weeks pregnant +0 days to 33 weeks +6 days (group B), 34 weeks pregnant +0 days to 36 weeks +6 days (group C), 37 weeks pregnant +0 days ~ 40 weeks +0 days (group D) and 40 weeks pregnant +1 days to 41 weeks +0 days (group E) for the experimental group; at the same time take the same period of gestational weeks simple preterm and full-term pregnancy patients as control group, according to Different types of placenta previa, gestational age corresponding to the birth weight of newborns. Results: There was no significant difference in weight of newborns between 37 weeks before pregnancy and that of premature newborns. There was no significant difference in weight of newborns between the 37th week and the 40th week when compared with the full-term pregnancy group. The body weight was higher than that of normal term pregnancy group, and was significantly higher in placenta accreta patients with placenta accreta. CONCLUSION: Placement of the placenta 40 weeks before pregnancy has no effect on fetal growth. However, placenta accreta should be monitored in patients with increased fetal weight after 40 weeks of gestation.
