Which of the following clinical findings are usually seen in meconium aspiration syndrome?

Signs of meconium aspiration syndrome include tachypnea, nasal flaring, retractions, cyanosis or desaturation, rales, rhonchi, and greenish yellow staining of the umbilical cord, nail beds, or skin. Meconium staining may be visible in the oropharynx and (on intubation) in the larynx and trachea.

Which of the following clinical manifestations are observed at birth on infants who have meconium aspiration syndrome?

Affected newborns have bluish skin and/or lips, rapid and labored breathing, and can make a grunting sound when breathing out. The diagnosis is based on seeing meconium in the amniotic fluid at birth, along with trouble breathing and abnormal chest x-ray results.

What are 4 common signs of respiratory distress in a newborn?

Babies who have RDS may show these signs:.
Fast breathing very soon after birth..
Grunting “ugh” sound with each breath..
Changes in color of lips, fingers and toes..
Widening (flaring) of the nostrils with each breath..
Chest retractions - skin over the breastbone and ribs pulls in during breathing..

Does meconium aspiration cause pulmonary hypertension?

Meconium aspiration is believed to cause persistent pulmonary hypertension syndrome of the newborn (PPHN) via vasoconstriction, whereas meconium has a relaxant effect on rat tracheal muscle.
