At this time, you should pay attention to daily care after induced abortion.

The ideal method of promoting cervical ripening is similar to its natural ripening process, will not cause excessive uterine contraction, will not affect uterine blood flow, and will not endanger the safety of the fetus and mother. There are many ways to promote cervical ripening, but there is still no perfect and effective method. Currently, the commonly used methods are divided into two categories: non-drug and drug:

1. Non-drug methods

① Artificial membrane stripping (basically not used); ② Artificial membrane rupture (not effective when used alone); ③ Water bag or Foley catheter (not routinely used); ④ Hygroscopic dilator or Lamicel rod (rarely used); ⑤ Nipple stimulation (not often used); ⑥ Acupuncture therapy (basically not used).

2. Drug therapy

① Oxytocin, small dose and low concentration intravenous drip; ② Prostaglandin PGE2 (routine use); ③ PGE2 gel intracervical administration (rarely used); ④ PGE2 vaginal controlled release tablets - Probeson (commonly used); ⑤ Misoprostol (not routinely used); ⑥ Vaginal placement of misoprostol; ⑦ Carboprostol suppository (basically not used); ⑧ Mifepristone (not used for late induction of labor).

Strictly follow aseptic techniques during surgery to avoid contact between the water bag and the vaginal wall.
