Difficult labor, in clinical terms, is characterized by slow or even stopped labor. Difficult labor is not only harmful to the physical and mental health of the pregnant woman, but also a threat to the life of the fetus. As the due date is approaching, many couples are worried about having a difficult labor. So, how can we avoid difficult labor? Labor is the process of pushing the fetus out of the uterus through the birth canal and the delivery of the placenta after the contraction of the uterus and the increase of abdominal pressure and amniotic fluid after labor. In this process, three major elements – labor force, birth canal and fetus – determine the possibility of obstructed labor. Accordingly, if these three decisive factors are safeguarded, obstructed labor can be largely reduced or even avoided. In order to avoid difficult births, pregnant mothers should be reminded to observe the following three principles during pregnancy: 1. Regular maternity checkups to reduce or eliminate maternal and fetal factors that cause difficult births. The role of maternity checkups is to check whether the mother has relevant diseases on the one hand, and to check whether the fetus is developing normally on the other hand, which can effectively monitor the whole pregnancy, so it is still very necessary. For example, fetal malposition is an important cause of obstructed labor, which can be detected early through maternity checkups. If you don’t do maternity checkups during pregnancy and only know that the fetal position is not correct when you are in labor, it will be very harmful to the smooth delivery and the health of the mother and fetus. Therefore, pregnant women should have regular maternity checkups to find out the problem early and solve it. 2, balanced nutrition, to avoid eating too much to cause fetal obesity. The fetus is too big, is now the most important reason for difficult delivery. Now people’s living standards have improved, plus they are only child, the family are very baby. So desperately give pregnant women nutrition, resulting in pregnant women fat fetus is also fat, bringing great difficulties to the birth. During pregnancy, it is advisable to control the weight gain of pregnant women within a reasonable range of 10 to 14 kg. If the baby’s head is too large (BPD over 10 cm), delivery will be difficult and once the BPD exceeds 10.5 cm, a normal delivery will be impossible. Therefore, it is enough to have balanced nutrition during pregnancy to ensure the nutrients needed for fetal development. 3, pay attention to exercise to help labor. Some pregnant women do not like to exercise themselves, or try not to exercise during pregnancy for the safety of the fetus, which is very undesirable. If the physical condition allows, you should do proper exercise during pregnancy. Childbirth is a very energy and physical exercise, pregnant mothers should build up energy for a smooth delivery. Some pregnant women do not have good enough stamina to sustain during labor, resulting in a prolonged labor, which can cause the fetus to lack oxygen. Therefore, it is better for expectant mothers to exercise more during pregnancy to strengthen their cardiorespiratory function and all aspects of their physical condition, so as to lay a good foundation for a smooth delivery.
