研究目的: |
1. 探究胎盘从低置状态自然转归为正常位置的中位时间及时间分布特征。 2. 分析不同初始位置(如前壁、后壁、侧壁等)胎盘低置状态的迁移时间差异。 3. 评估影响胎盘位置迁移的相关因素(如母体年龄、孕产史、子宫形态、胎盘附着部位等)。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. Investigate the median time and temporal distribution characteristics of the natural transition of the placenta from a low-lying state to a normal position. 2. Analyze the differences in migration time of low-lying placenta with different initial positions (such as anterior wall, posterior wall, lateral wall, etc.). 3. Assess the relevant factors affecting placental position migration (such as maternal age, obstetric history, uterine morphology, placental attachment site, etc.). |
