Insights
Acute lung injury in children alters the surfactant system through inflammation and injury. This review explores the pathophysiology of lung injury and surfactant therapy for respiratory failure.
Area of Science:
- Pediatric critical care medicine
- Pulmonology
- Biochemistry of lung surfactants
Background:
- Acute lung injury (ALI) in pediatric patients involves complex pathophysiological mechanisms.
- The endogenous surfactant system plays a crucial role in maintaining lung function and is significantly impacted in ALI.
- Inflammation, vascular dysfunction, oxidant stress, cellular damage, and edema are key contributors to ALI pathophysiology.
Purpose of the Study:
- To examine the pathophysiology of acute lung injury in children.
- To review the role and application of surfactant therapy in treating acute respiratory failure in infants and children.
Main Methods:
- Literature review and synthesis of existing research on pediatric acute lung injury.
- Analysis of the mechanisms affecting the endogenous surfactant system in ALI.
- Examination of clinical evidence regarding surfactant use in pediatric respiratory failure.
Main Results:
- Multiple mechanisms, including inflammation and cellular injury, disrupt surfactant function in pediatric ALI.
- Surfactant dysfunction is a critical component of the respiratory compromise seen in ALI.
- Surfactant therapy is a potential treatment modality for acute respiratory failure in this population.
Conclusions:
- Understanding the multifaceted pathophysiology of ALI is essential for effective treatment strategies.
- Surfactant replacement or modulation may offer therapeutic benefits for children with acute respiratory failure due to ALI.
- Further research into surfactant's role in pediatric ALI is warranted.
Abstract:
In children with acute lung injury the endogenous surfactant system is altered via a variety of different mechanisms, including inflammation, vascular dysfunction, oxidant injury, cellular injury and oedema. This article examines the pathophysiology of acute lung injury and surfactant use for treatment of acute respiratory failure in infants and children.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
