Can meconium aspiration cause pneumonia?

Meconium particles in the amniotic fluid can block small airways and prevent a baby from breathing properly, causing respiratory distress. If this occurs, some babies may need the help of a mechanical breathing machine. A baby who has inhaled meconium may also develop an infection, which can cause pneumonia.

What causes cyanosis in bacterial pneumonia?

It is evident that the cyanosis of pneumonia patients is due to the incomplete saturation of venous blood with oxygen in the lungs, and that the various shades of blue observed in the distal parts are caused by an admixture of reduced hemoglobin and oxyhemoglobin in the superficial capillaries.

What are the most common causes of bacterial pneumonia in neonates?

Pneumonia in neonates younger than three weeks of age most often is caused by an infection obtained from the mother at birth. Streptococcus pneumoniae and viruses are the most common causes in infants three weeks to three months of age.

Can meconium aspiration cause asthma?

Living with meconium aspiration syndrome However, babies who experienced MAS may be at higher risk for an asthma-like disease called “reactive airway disease.” This can cause wheezing, coughing, and shortness of breath.

What happens if baby swallows amniotic fluid?

When the thick meconium mixes into the amniotic fluid, it is swallowed and breathed into the airway of the fetus. As the baby takes the first breaths at delivery, meconium particles enter the airway and can be aspirated (inhaled) deep into the lungs.

Why does hypoxia develop with pneumonia?

Arterial hypoxemia early in acute pneumococcal pneumonia is principally caused by persistence of pulmonary artery blood flow to consolidated lung resulting in an intrapulmonary shunt, but also, to a varying degree, it is caused by intrapulmonary oxygen consumption by the lung during the acute phase and by ventilation- …

Why does hypoxia cause cyanosis?

The presence of abnormal hemoglobin causes significant impairment in the oxygen-carrying capacity of the blood. This can cause tissue hypoxia which can manifest clinically as cyanosis.

What is the primary mode of prevention for pneumonia in a child?

Immunization against Hib, pneumococcus, measles and whooping cough (pertussis) is the most effective way to prevent pneumonia. Adequate nutrition is key to improving children’s natural defences, starting with exclusive breastfeeding for the first 6 months of life.
