On the day before cesarean section, 2 ml of maternal blood is collected as a research sample in addition to normal blood collection.
Perform cesarean section as usual until lower uterine exposure: laparotomy
At the stage where the lower uterus can be exposed, intraoperative ultrasound is used to confirm the position of the fetus and appendages, then the lower uterine muscle layer is incised to confirm the uveal bulge, and the bulge is punctured with a 20-gauge needle. Collect 2 mL of amniotic fluid.
Child delivery and placenta delivery after artificial rupture. Thereafter, uterine suture and abdomen are performed as usual cesarean section.
After fetal delivery, normal umbilical arterial blood is collected, and 2 ml of umbilical venous blood is collected from the umbilical vein as a research sample.
TSH and freeT4 in amniotic fluid, umbilical vein blood, and maternal blood are measured by ECLIA method.
