When the fetus is hypoxic in utero, it depends mainly on the severity of the hypoxia. When the fetus is mildly hypoxic, oxygen is given to the pregnant woman, which can improve the hypoxic state. When the fetus is severely hypoxic and the oxygen is not relieved, the pregnancy needs to be terminated as soon as possible. In order to avoid endangering the life of the fetus. I. Mild hypoxia: 1. Oxygen inhalation: Once the fetus is found to have hypoxia, it should immediately seek medical attention and supplement oxygen. Oxygen can increase the blood oxygen content of the pregnant woman, which can be delivered to the fetus through the placenta, which can improve the state of hypoxia. If the fetal heart rate returns to normal, you can continue to observe; 2. Left side lying: it can reduce the pressure of the uterine body on the inferior vena cava, make the blood flow delivery more smoothly, increase the blood supply of the uterus and the placenta, which can effectively improve the hypoxia. Second, severe hypoxia: 1, the opening of the uterus is complete: patients whose fetal previa reaches 3cm below the level of the sciatic spine can choose to perform delivery as soon as possible; 2, the opening of the uterus is not open: if the cervix is not completely dilated, the fetal distress is serious, the fetal heart rate is abnormal, and after oxygen and other treatments are ineffective, a cesarean section is feasible to avoid brain damage aggravated by intrauterine hypoxia of the fetus. The labor and delivery examination should not be neglected, as it can detect various factors that may cause intrauterine hypoxia in the fetus and can provide timely diagnosis and treatment.
