How long does it take to have a first child?

The first child needs more than ten hours. Oxytocin is a prostaglandin preparation. Its mechanism of action is to soften the cervix and shorten the cervical canal after insertion into the vagina. After insertion, it is necessary to observe the uterine contractions of the pregnant woman and the fetal heart. Continuous fetal heart monitoring is needed, because if the uterine contractions are very strong, it is easy to cause hypoxia in the fetus. If vaginal fluid, strong contractions, or five contractions occur in ten minutes after the drug is inserted, the drug needs to be removed and the contractions continue to be observed after the drug is taken.
