CVS(Chorionic Villus Sampling) 一萬例
從不開預防性抗生素，無菌操作比較重要

4.Ladin sign:子宮前面正中處，有一柔軟的點出現。
5.Mc Donald sign:指屈曲子宮頸底部時沒有阻力，使子宮底易於屈曲而接觸子宮頸。
6.Braun von fernwald sign:妊娠第五週，受精卵著床處變軟，增大使子宮呈不規則球形。
7.Piskacek sign:指腹部似種瘤呈不對稱腫大。
8.Physiologic erosion:生理性糜爛、因局部血流增加，組織變軟易生糜爛屬生理變化。

Parikh's formula is a
calculation method that considers cycle duration. Naegele's rule assumes an
average cycle length of 28 days, which is not true for everyone. EDD is
calculated using Parikh's formula by adding nine months to the start of the
last menstrual period, subtracting 21 days, then adding duration of previous
cycles.
