Induced labor refers to the use of artificial methods to induce uterine contractions to end pregnancy after 12 weeks of pregnancy due to maternal or fetal reasons. According to the gestational age at the time of induced labor, it can be divided into mid-term induced labor (14 to 28 weeks) and late-term induced labor (after 28 weeks).

Methods of inducing labor

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).

Pre-labor induction check

1. Ask about the medical history in detail, including past history, bleeding history, history of liver and kidney diseases, menstrual history, pregnancy and delivery history, and the course of this pregnancy.

2. General and gynecological examination, routine leucorrhea testing.

3. Measure body temperature, pulse, blood pressure, blood test, urine routine, etc., and if necessary, measure liver and kidney function, chest X-ray, and electrocardiogram.

4. Severe cervicitis or heavy secretions require treatment first, and surgery can only be performed after the condition improves; antibiotics are given before surgery to prevent infection. If necessary, secretion culture and drug sensitivity test should be performed.

5. Patients who are in advanced pregnancy, have hypoplastic cervix, small cervical os, and long cervical canal need to be given certain medications before surgery.

6. Perform B-ultrasound to locate the placenta when necessary. It is contraindicated for patients with low-lying placenta.
