The duration of opening 1 to 2 fingers is usually not clear, but varies from person to person, and is mainly related to the number of births and contractions. 1, the number of births: as women who have given birth once or more, when the uterus starts contracting, the external cervical opening expands, and its resistance is smaller than that of primiparous women, so the labor progresses faster in primiparous women. If the contractions are regular and the fetal position and fetal condition are good, the time from 1 finger to 2 fingers can be as short as tens of minutes, or can last for several hours; while the time from 1 finger to 2 fingers is relatively long for primiparous women due to the slow dilatation of the cervix, which is 2-4 hours on average, and up to 10 hours for very few primiparous women; 2, contractions: if the contractions are regular and good, the time from 1 finger to 2 fingers can be shortened, so it is recommended that the women can keep their emotions stable during contractions by deep breathing and other ways to avoid consuming Therefore, it is recommended to keep the mother emotionally stable during contractions by breathing deeply to avoid consuming too much energy, which will help the opening of the uterus. Usually, if the contractions are regular, the time of opening 1 to 2 fingers is not significantly prolonged, and the fetal heart monitoring is good and there is no abnormality in the fetus, it is considered as normal development of labor. From the time of labor to the opening of the uterus 4-6 cm, more than 20 hours for primigravida and more than 14 hours for menstruating mothers is called prolonged latent period, first of all, we need to find the cause, we can use sedatives to rest, and after the pregnant woman’s strength recovers as much as possible, then consider oxytocin to induce labor.
