A cesarean section can be performed at 38 weeks of gestation if indicated. At this time, the fetus is full-term, its organs are largely developed and its survival rate is high. The organs of the fetus at 38 weeks of pregnancy are well developed, the lung function is slowly starting to function, the immune system is gradually improving, and the body fat is gradually increasing every day. At this time, the fetus is about 47.5 cm long and weighs about 3100 g. The heart, lungs, liver and other important organs have all been formed and have the ability to survive independently outside the mother’s body. If the fetus meets the indications for cesarean section, the operation can be performed. If the fetus is too large and the pregnant woman’s pelvis cannot accommodate the fetal head; the fetus has intrauterine hypoxia, or the delivery cannot be delivered smoothly for a short time due to hypoxia during labor. Pregnant women with serious pregnancy complications, such as combined heart disease, diabetes, chronic nephritis, etc., and with a history of multiple miscarriages or bad deliveries, may undergo a cesarean section as prescribed by the doctor. The doctor will give appropriate advice according to the maturity of the placenta and the condition of the amniotic fluid. Therefore, whether to perform a cesarean section at 38 weeks of pregnancy should be done according to medical advice.
