Medically, pain is divided into 12 levels, with the higher the level the more intense the pain. Grade 1 pain is the lightest, the pain level is equivalent to being bitten by a mosquito; being slapped is equivalent to grade 4 pain, the pain of mutilation caused by external force is equivalent to grade 10 pain, and the pain caused by contractions in women giving birth is grade 12 pain, the highest level of pain, so you can imagine how painful it is to give birth to a child. Induced labor is the termination of pregnancy after 12 weeks of gestation by artificially inducing contractions in the uterus. In general, the risk of inducing labor is higher the older the fetus is. At four months of age, the fetus is basically formed, and after the induction of labor, the mother will experience abdominal pain (i.e., contractions) induced by drugs, at which time the opening of the uterus will open and the fetus will be delivered. As mentioned above, the pain level of labor contractions is 12, so it is also unusually painful to induce labor. However, pain varies from person to person, as each person has different pain tolerance and sensitivity to pain, so their perception of pain also varies. The so-called painless induction is the injection of anesthesia before entering the delivery room, so that the patient does not feel pain during the induction, but before the induction, the pain of contractions still exists. Therefore, before the birth of a child is determined to do a good job of contraception to avoid induction of labor.
