There is no specific clinical value for the probability of accidents during labor, which varies from person to person and is generally related to the physical condition of the mother, her age, the condition of the fetus, and so on. If all the pregnancy tests are normal and there is no pathologic pregnancy, the chance of an accident during delivery is usually very small. During vaginal delivery in the hospital, the doctor will give the mother a systematic examination to find out if she can have a normal delivery, and if the risk of a normal delivery is relatively high, the doctor will usually ask the mother to consider having a cesarean section for delivery. Pregnant women should pay attention to rest, relax their emotions, eat more warm food, usually do not have strenuous activities, observe the changes in appetite, do not blindly activities in the late stage, pay attention to protect the fetus. Pregnant women should follow the doctor’s instructions to carry out various examinations during pregnancy, to understand their own condition as well as the condition of the fetus, and choose the appropriate way of delivery according to the actual situation in order to ensure a smooth delivery.
