Amniotic fluid aspiration syndrome

Symptoms of amniotic fluid inhalation syndrome

Amniotic fluid aspiration syndrome refers to the fetus during childbirth or in the uterus a large number of inhalation of amniotic fluid disease, then the fetal amniotic fluid aspiration syndrome symptoms what?

Because of the large number of inhaled amniotic fluid, the most common symptom is dyspnea. Babies with less inhalation of amniotic fluid may have dyspnea for a time, and can heal themselves. The heavier patients will suffer from dyspnea and cyanosis. Inhalation of 40% oxygen can maintain normal PaO2 and PaCO2. Severe patients may die within a few minutes of life or develop severe dyspnea and cyanosis within a few hours of life. General oxygen therapy is ineffective for patients with severe amniotic fluid aspiration syndrome, requiring mechanical ventilation and other comprehensive treatment. In addition, some children start with only mild respiratory distress, but a few hours later due to chemical pneumonia and deterioration of the disease, serious cases will also occur death.

After inhalation of thick meconium-contaminated amniotic fluid, the infant’s chest enlarges to a barrel-shaped chest due to gas retention. Such fetuses usually have shortness of breath, reduced breathing sounds, or moist rales and wheezing. Cyanosis and dyspnea aggravated when infants developed pneumothorax.

Fetuses exposed to meconium-contaminated amniotic fluid for more than 4-6 hours in utero often show yellowish-green or dark-green skin, nails and umbilical cord. In addition, other children may have persistent pulmonary hypertension. All in all, no matter what symptom it is, it is very critical for infants.

Causes of amniotic fluid inhalation syndrome

Many pregnant mothers know that amniotic fluid aspiration syndrome is very serious for their babies, but many pregnant mothers do not understand the causes of amniotic fluid aspiration syndrome. Now, Xiaobian is going to show you every treasure.

When the fetus has intrauterine distress or intrapartum distress, more amniotic fluid will be inhaled in utero or during childbirth. Generally speaking, amniotic fluid inhalation syndrome is due to early fetal hypoxia, because the fetal hypoxia can cause colony reflex, and excrete meconium, then the fetus will appear true respiration, then it is easy to meconium amniotic fluid keratinocytes inhaled together. If the thin meconium amniotic fluid or inhalation is not large, can lead to partial obstruction, causing obstructive emphysema, if alveolar rupture can lead to interstitial emphysema or pneumothorax. In addition, the occurrence of yellow-green fetus is due to fetal meconium pollution at birth, if the fetus immersed in meconium amniotic fluid for 4-6 hours, nails can be stained yellow-green, 10-12 hours of umbilical cord, fetal fat, placental amniotic membrane can be stained with meconium color. Pulmonary signs are related to the amount and thickness of meconium inhaled. Breathing sounds can be asymmetrical if there are breathing movements on both sides of the pneumothorax.

Babies with amniotic fluid aspiration syndrome developed pneumonia because meconium and amniotic fluid stimulated respiratory mucosa or secondary infection caused pneumonia. Some babies enter convalescence, their inhalation is absorbed or phagocytosis, serious cases of fibrosis, emphysema and other pathological changes.

Prevention of amniotic fluid inhalation syndrome

Knowing how much amniotic fluid aspiration syndrome is harmful to babies, many pregnant mothers want to know, how to prevent amniotic fluid aspiration syndrome? Now, let’s get together with Xiaobian.

Amniotic fluid aspiration syndrome is very unhealthy for babies, but the prevention of amniotic fluid aspiration syndrome in our lives can be prevented. First of all, the most important thing is regular production inspection. As the gestational age increases, the baby becomes more and more mature, the fetal stool gradually moves down close to the anus, when the anal dilator muscle relaxes, the fetal stool is discharged. Another situation is when the fetal baby appears hypoxia, will stimulate the sympathetic nerve, resulting in the anal sphincter suddenly relaxed, discharged fetal stool. When the fetal stool is excreted into amniotic fluid, amniotic fluid is yellow-green or dark-green, at this time the baby should be careful to inhale meconium through amniotic fluid. And if the mother wants to reduce the possibility of the baby inhaling meconium as much as possible, regular obstetric examination can prevent abnormal conditions.

It is suggested that pregnant mothers should cooperate with medical staff when approaching the expected period of labor to avoid prolonging the expected period of labor and fetal hypoxia, thus causing amniotic fluid aspiration syndrome. Secondly, follow the doctor’s advice, when necessary, use uterine relaxants to prevent acute hypoxia caused by acute childbirth. Pregnant mother at home should monitor fetal movement and fetal heart, and monitor the baby’s situation at any time.

Can amniotic fluid inhalation syndrome affect fetal intelligence?

Amniotic fluid inhalation syndrome, as the name implies, refers to the syndrome caused by inhalation of amniotic fluid. Therefore, many pregnant mothers have such worries, that is, amniotic fluid inhalation syndrome will affect fetal intelligence?

Fetal airway obstruction, pulmonary inflammation and a series of systemic symptoms of amniotic fluid contaminated by meconium inhalation occur in the uterus or during childbirth. Respiratory distress accompanied by other organ damage occurs in a group of syndromes after birth, which are more common in full-term and postpartum infants. The severity of symptoms is related to the physical characteristics of inhaled amniotic fluid (such as suspension or lump meconium). Because the fetus will defecate later, the amniotic fluid will be polluted more or less. Inhalation of small amounts of mixed amniotic fluid can be asymptomatic or mild. Respiratory distress is common. But if the amniotic fluid is polluted, it will lead to the symptoms of fetal hypoxia. Serious contamination of amniotic fluid can lead to aspiration pneumonia, hypoxia and encephalopathy.

For children with amniotic fluid contamination, fetal hypoxia can lead to symptoms, the consequences of fetal hypoxia is very dangerous will affect life. In addition, after normal fetal contamination can be born smoothly, it may also lead to the baby’s slow speech, slow reaction and other corresponding adverse consequences. This is because amniotic fluid contamination enters the blood circulation, and then stimulates the brain, causing chronic neurotoxic symptoms of brain cells, affecting the normal development of the child’s brain. In addition, inhalation of contaminated amniotic fluid can easily lead to pneumonia.
