If the newborn’s amniotic fluid is third degree contaminated, if the mouth of the uterus is fully opened and the fetus has a good heartbeat, the baby needs to be delivered immediately; if the mouth of the uterus is not fully opened and the fetus shows symptoms of hypoxia, the baby needs to be delivered by cesarean section in time, not waiting for observation. If the newborn’s amniotic fluid is third degree contaminated, it means the amount of amniotic fluid is reduced, the amniotic fluid is dark green, the fetus has symptoms of hypoxia and intrauterine distress, and the situation is more critical. If the mouth of the uterus is fully opened and the fetal heart is good, the baby needs to be delivered immediately; if the mouth of the uterus is not fully opened and the fetus shows symptoms of hypoxia, the baby needs to be delivered by cesarean section in time, otherwise the fetus will easily die in the womb due to hypoxia. In addition, third-degree contamination of newborn amniotic fluid, whether delivered vaginally or by cesarean section, is likely to cause neonatal respiratory distress syndrome, so the baby needs to be sent to the neonatal unit for treatment in a timely manner after delivery. In conclusion, it is recommended to deliver the fetus early to avoid serious consequences.
