When pregnant mothers go to the hospital for prenatal check ups in the later stage, doctors will ask them to pay more attention to their reactions and rest, to avoid any unexpected situations that may cause danger to the fetus in their belly, such as amniotic fluid and fecal contamination before birth. So what are the reasons for amniotic fluid fecal staining?
The cause of meconium stained amniotic fluid may be due to the conditioned reflex caused by fetal hypoxia in the mother's womb. The fetus will excrete meconium, which will then merge into the amniotic fluid, leading to amniotic fluid contamination. If the fetus breathes again, it will inhale meconium and amniotic fluid into the body, causing amniotic fluid infection. meconium and amniotic fluid can irritate the respiratory mucosa or cause secondary infection, which can lead to pneumonia.
If the fetus is immersed in meconium and amniotic fluid for about 6 hours, the fetal toenails will be stained yellow green by meconium, and around 12 hours, the fetal umbilical cord, placenta, amniotic membrane, etc. will be stained meconium color by meconium. Newborns' breathing can also be severely affected, and symptoms such as slow heartbeat and shock may occur. After birth, the fetus may experience rapid breathing or even difficulty breathing due to spontaneous breathing.
The cause of meconium stained amniotic fluid is usually due to insufficient oxygen content in the mother's blood, which leads to intrauterine hypoxia in the fetus, causing fetal respiratory distress and resulting in hypoxia. The fetal heart rate will be stimulated by vagus nerve due to continuous hypoxia, accelerating intestinal peristalsis. The fetus will excrete feces and contaminate amniotic fluid. At this time, it is necessary to strengthen fetal monitoring, provide appropriate oxygen therapy, and enhance exercise during pregnancy to protect the fetus. If problems are found during pregnancy, they should be actively treated.
