Meconium aspiration syndrome: a comprehensive review

Area of Science:

• Neonatal Medicine
• Pediatric Pulmonology
• Critical Care

Background:

• Meconium aspiration syndrome (MAS) is a significant cause of neonatal morbidity and mortality.
• Pathophysiological mechanisms include airway obstruction, inflammation, surfactant inactivation, and persistent pulmonary hypertension of the newborn (PPHN).

Purpose of the Study:

• To review the complex respiratory management of MAS.
• To emphasize the importance of individualized care and PPHN management.

Main Methods:

• Review of current literature on MAS pathophysiology and respiratory support strategies.
• Discussion of challenges in mechanical ventilation for MAS patients.

Main Results:

• Supplemental oxygen and non-invasive support are initial therapies.
• Mechanical ventilation can be challenging due to atelectasis and air trapping.
• No single ventilatory modality is universally superior.

Conclusions:

• Respiratory management for MAS should be tailored to patient pathophysiology, severity, and clinician expertise.
• Early identification and management of PPHN are crucial for improving outcomes.
