The time it takes to induce labor from pain to birth varies from person to person and is usually between 6-10 hours. Induced labor is mainly performed externally to help facilitate the contractions of the uterus and then to deliver the fetus. The time from the onset of labor to the onset of pain varies from person to person due to their physical condition, sensitivity to drugs, intensity of contractions, size of the baby, fetal position, and pelvic condition. In some cases, due to the small size of the fetus and the small size of the fetus during the vaginal trial of labor or induction of labor, and if the woman’s pelvis is wide and easy to deliver, she will be able to achieve dilatation of the uterus and smooth delivery of the fetal head in a very short time under the stimulation of very effective regular contractions. However, in some women, even if the conditions for induction of labor are very good and regular contractions occur, the progress of labor may be very slow due to pelvic abnormalities, large fetus and abnormal fetal position, and it may take longer to deliver after regular contractions. Therefore, in the process of induction of labor, if very regular and effective pain starts to appear, most of it means that labor has already started and the time of delivery can be judged according to the speed of opening of the uterus and the degree of fetal head descent, so that the situation can be handled accordingly.
