How long does it take to deliver after the fourth finger is opened is not a generalization, most pregnant women are in about 4 to 8 hours, the mouth of the uterus will be fully opened, and abdominal pressure can be used to deliver. However, different maternal physical condition, uterine contraction, etc., there will be differences in the time of labor, and there will also be differences between menstruating women and primiparous women, so the time is not fixed.
1. Maternal constitution: different maternal constitution is not the same, although all are open four fingers, but the time of labor will be different. The size of the pelvis and the size of the fetus will affect the time of labor. Menstruating women have a faster labor time and may deliver within a few hours, while primigravid women have a longer labor time.
2. Uterine contractions: If the uterus is in good contraction after the fourth finger is opened, the uterus may open fully within 4 hours or so, and the baby will be born more quickly. However, a few pregnant women may have poor uterine contractions and may not be able to deliver the baby for about 8 hours even after the fourth finger is opened.
Pregnant women with four fingers can walk around as much as they are allowed to, which can help with labor, and they need to cooperate with the midwife during labor.
