There is no direct causal relationship between the failure of primiparous women to enter labor and the success rate of labor induction, therefore, the success rate of labor induction cannot be projected purely by entering labor. Usually, the success rate of labor induction is related to the condition of the birth canal of the pregnant woman, cervical maturity, the size of the fetus, the force of delivery and other factors. When the fetus has not yet entered into the pelvis, the primiparous woman can be given labor induction if contraindications to labor induction, such as cephalo-pelvic asymmetry, are ruled out; however, there is no direct cause-and-effect relationship between the success rate of labor induction and the lack of fetal pelvic instillation. If the pregnant woman’s birth canal is in good condition, cervical ripeness is high, the fetus is of appropriate size, and the force of delivery is good, the success rate of labor induction is relatively high, but there are risks of intrauterine distress and uterine rupture in the process of labor induction, which can seriously jeopardize the life of the mother and child, so the patient should not blindly pursue labor induction. If the patient has the need to induce labor, it must be carried out under the close guidance of a professional physician, so as to avoid blindly inducing labor, which may lead to an adverse pregnancy outcome.
