Usually during labor, if a woman opens to 4 fingers, the baby can be born successfully in about 3-4 hours, but the time of birth is affected by various factors such as the size of the fetus, the degree of fetal head descent, and the softness of the cervical opening, so the exact time of birth varies from person to person. If the mother’s contractions are strong, the fetal position is relatively positive, the fetus is small, the fetal head is descending faster, and the cervical texture is softer, the opening of the uterus will be faster and the time required for delivery will be shorter. On the contrary, if the pregnant woman is slow to open her fingers, if the contractions are weak, if the fetus is large, if the fetal position is not correct or if the woman’s cervix is not in good condition, the opening of the uterus may be slower, resulting in a longer delivery time. A vaginal or anal examination is usually done during labor to observe how quickly the opening of the uterus is opening, once every 4 hours at first, to determine if the woman can deliver vaginally. In addition, if the opening of the uterus is fast and the fetal heartbeat is good, vaginal delivery is more likely. If the opening of the uterus is slow and the fetal head does not descend, or if, after dynamic observation, there is cloudy amniotic fluid, slow fetal heartbeat or even intrauterine distress, the pregnancy should be terminated by cesarean section in time. During labor, pregnant women should keep their mood calm, avoid excessive tension and anxiety, and avoid excessive emotional ups and downs. It is recommended that women should replenish the energy needed before delivery to avoid physical exhaustion. After delivery, it is also important to replenish nutrition in time, pay attention to rest and get enough sleep.
