If a newborn baby chokes on amniotic fluid, it may show the following sequelae: first, it shows a decrease in respiratory function, because after choking on amniotic fluid, some amniotic fluid is contaminated by meconium, which will stimulate the respiratory tract, leading to respiratory inflammation and chemical damage, resulting in a decrease in respiratory function; second, it will cause pulmonary hypertension, because after the respiratory tract is damaged, it will cause hypoxia and acidosis of the body. Secondly, it can cause pulmonary hypertension, because after the respiratory tract is damaged, it will cause hypoxia and acidosis, and hypoxia and acidosis will cause pulmonary artery spasm. Pulmonary artery spasm will cause the resistance of pulmonary artery to increase, thus causing continuous pulmonary hypertension, which will lead to high pulmonary artery pressure, thus affecting respiratory function and growth and development.
