    Summary
    This summary is machine-generated.

    Pneumopericardium (PPC) in neonates, often linked to prematurity and respiratory support, presents a high mortality risk. Radiographic signs like the "halo" sign are key diagnostic indicators.

    Area of Science:

    • Neonatal Medicine
    • Pediatric Radiology
    • Critical Care

    Background:

    • Pneumopericardium (PPC) is a serious condition in neonates, frequently affecting premature infants with respiratory distress.
    • Ventilatory assistance, common in these infants, is a significant risk factor for PPC development.

    Purpose of the Study:

    • To review clinical data and radiographic findings in neonates diagnosed with pneumopericardium.
    • To identify contributing factors, diagnostic signs, and outcomes associated with PPC in this population.

    Main Methods:

    • Retrospective review of clinical data and radiographic images from 50 neonates with confirmed PPC.
    • Analysis of predisposing conditions, concurrent medical interventions, and radiographic signs.

    Main Results:

    Related Experiment Videos

    • The "halo" sign was the primary radiographic indicator of PPC, present in 96% of cases.
    • Contributing factors included prematurity, low birth weight, hyaline membrane disease, ventilatory support, and improper endotracheal tube placement.
    • Overall mortality was 72%, with 33% of deaths directly attributed to PPC.

    Conclusions:

    • PPC is associated with high mortality in neonates, particularly those with underlying respiratory conditions requiring mechanical ventilation.
    • While contributory factors are identifiable, the precise reason for PPC development in some infants remains unclear.
    • Long-term prognosis is more influenced by the severity of the primary lung disease and other complications than by PPC itself.
