Whereas oxygen, continuous positive airway pressure (CPAP) and mechanical ventilation are the mainstays of treatment of pulmonary conditions in newborns, there are a number of adjunctive therapies that may improve the pulmonary function of these infants. These include the use of bronchodilators and diuretics given either systemically or through the inhaled route, mucolytic agents, and anti-inflammatory agents. This chapter gives an overview of the use of the most-studied agents including aerosolized bronchodilators, systemic and inhaled diuretics, and systemic and inhaled corticosteroids in the treatment and prevention of, where appropriate, respiratory distress syndrome, bronchopulmonary dysplasia, and meconium aspiration syndrome. Evidence on the use of mucolytic agents including acetylcysteine and deoxyribonuclease, and the anti-inflammatory agents including the macrolide antibiotics, cromolyn, pentoxyfylline, and recombinant human Clara cell protein are also reviewed.

Atelectases, over-inflation of ventilated regions of the lung, and consecutive pneumothoraces are life-threatening conditions in mechanically ventilated infants with acute respiratory distress syndrome-type respiratory syncytial virus-pneumonia. The accumulation of viscous secretions secondary to impaired mucociliary clearance in the more proximal parts of the bronchial tree is the prerequisite for atelectases and also prevents the delivery of inhaled medications to the more distal parts of the lung. Herein, we describe four moderately premature infants with respiratory failure on mechanical ventilation, displaying a total of 20 radiologically verified new atelectases that were treated by bronchoscopic interventions with consecutive suctioning of secretions, restoration of the surfactant film within the airways, and deposition of recombinant human deoxyribonuclease at the first segment level of the bronchial tree. On 13 occasions (65%), resolution of atelectases was proven by chest X-ray and resulted in improved lung function. We conclude that these bronchoscopic interventions may contribute to the restoration of the gas exchange area in moderately premature infants with acute respiratory distress syndrome-type respiratory syncytial virus-pneumonia.
