Meconium Aspiration Syndrome

Intrapartum meconium aspiration may cause an inflammatory pneumonitis and a mechanical bronchial obstruction with respiratory distress syndrome. The findings include tachypnea, rales, cyanosis or decreased oxygen saturation. The diagnosis is suspected when a respiratory distress syndrome occurs after birth and contains the amniotic fluid meconium, and confirmed by a chest x-ray. Treatment consists of thorough vacuuming after birth before the baby takes its first breath. Then the breathing, to the extent necessary, supported. The prognosis depends on the underlying physiological causes.

Intrapartum meconium aspiration may cause an inflammatory pneumonitis and a mechanical bronchial obstruction with respiratory distress syndrome. The findings include tachypnea, rales, cyanosis or decreased oxygen saturation. The diagnosis is suspected when a respiratory distress syndrome occurs after birth and contains the amniotic fluid meconium, and confirmed by a chest x-ray. Treatment consists of thorough vacuuming after birth before the baby takes its first breath. Then the breathing, to the extent necessary, supported. The prognosis depends on the underlying physiological causes. Etiology A Mekoniumentleerung is noted in 10-15% of births. Physiological stress during labor and birth (eg. B. hypoxia through the umbilical cord or placental insufficiency by infections) may cause the fetus to be emptied before the birth of meconium into the amniotic fluid. During childbirth aspirate 5% of newborns meconium that can trigger a lung injury and respiratory distress syndrome, meconium aspiration syndrome called. Children who are born after the official date of birth with reduced fruit water, are at greater risk because the meconium is not diluted and thus may cause airway obstruction. Pathophysiology The mechanisms by which aspiration leads to clinical symptoms are non-specific cytokine airway obstruction surfactant inactivation pneumonitis Underlying physiological stressors can also help. Is a complete closure of the bronchi before, this results in atelectasis, a partial transfer leads to entrapment of air during exhalation, followed by a hyperinflation of the lungs and pulmonary possible leak (Pulmonary Air leak syndrome) with a pneumomediastinum or pneumothorax. Persistent pulmonary hypertension may be associated with meconium aspiration as a comorbid condition or because of persistent hypoxia (Persistent pulmonary hypertension of the newborn). Newborns can aspirate, which can cause respiratory distress syndrome and may show symptoms of aspiration pneumonia on chest x-ray during birth also vernix, amniotic fluid and maternal or fetal blood. Symptoms and discomfort symptoms are tachypnea, nasal flaring, retractions, cyanosis or low oxygen saturation, crackle, crackles and yellow-green color of the umbilical cord, the nail bed or skin. The Mekoniumfarbe can be seen in the oropharynx and intubation in larynx and trachea. Newborns with trapped air can have a barrel chest and signs and findings of pneumothorax, a pulmonary interstitial emphysema and pneumomediastinum have one (Pulmonary Air leak syndrome: pneumomediastinum). Diagnosis meconium breathlessness Characteristic radiological findings Diagnosis is suspected when a newborn respiratory distress shows when accompanied by meconium-stained amniotic fluid. The diagnosis is confirmed by a chest x-ray that shows hyperinflation with variable areas of atelectasis and flattening of the diaphragm. Initial radiographic findings may be confused with the results of transient tachypnea of ??the newborn (Transient tachypnea of ??the newborn). In the Lungenfissuren or pleural fluid can be seen and air be present in the soft tissues or the mediastinum. Since the meconium promotes bacterial growth, a meconium aspiration syndrome sometimes can not be distinguished from a bacterial pneumonia. Therefore, blood cultures and cultures should be removed from the tracheal aspirate.
