Neonatal artificial ventilation may lead to long-term respiratory issues like airway obstruction and hyperinflation in children. Follow-up lung function tests and chest imaging are recommended for these children.

Area of Science:

  • Pediatric Pulmonology
  • Neonatal Intensive Care
  • Respiratory Medicine

Background:

  • Neonatal artificial ventilation is a critical intervention for premature infants.
  • Long-term respiratory sequelae in children previously requiring mechanical ventilation are not fully understood.
  • Bronchopulmonary dysplasia (BPD) is a known complication of neonatal respiratory support.

Purpose of the Study:

  • To assess the long-term pulmonary function and respiratory health of children who underwent neonatal artificial ventilation.
  • To identify potential risk factors and complications associated with neonatal ventilation.
  • To evaluate lung function, exercise capacity, and cardiac status in this cohort.

Main Methods:

  • A cohort of 40 children (8-10 years old) with a history of neonatal artificial ventilation were studied.

  • Pulmonary function tests (spirometry, nitrogen washout), bicycle exercise tests, pulse oximetry, ECG, vectorcardiogram, and chest radiography were performed.
  • Gestational age, birth weight, and indication for ventilation (e.g., hyaline membrane disease) were recorded.

    • Main Results:

    • Bronchopulmonary dysplasia was diagnosed in 27% of the children.
    • Airway obstruction was prevalent, affecting 10/11 with BPD and 9/29 without.
    • Significant improvements in FEV1 were noted after terbutaline inhalation. Hyperinflation and increased functional residual capacity were common in those with abnormal radiographs.
    • Oxygen saturation decreased significantly during maximal exercise in both groups.

    Conclusions:

    • Children with a history of neonatal ventilation exhibit persistent respiratory abnormalities, including airway obstruction and hyperinflation.
    • Abnormal chest radiographs correlate with altered lung volumes.
    • The findings underscore the need for ongoing monitoring of lung function and radiographic changes to anticipate future respiratory problems.
