[Atelectasis without bronchial obstruction]

G Favez, B Raaflaub

    Schweizerische Medizinische Wochenschrift
    |February 12, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Acute pneumonia can cause temporary lung collapse (atelectasis) without airway blockage. This reduced lung volume, seen in shock lung and pulmonary embolism, may indicate a surfactant system disorder.

    Area of Science:

    • Pulmonary Medicine
    • Critical Care
    • Respiratory Physiology

    Context:

    • Presents five patients with acute pneumonia experiencing transitory atelectasis.
    • Observes reduced lung volume in these patients, distinct from bronchial obstruction.
    • Compares this phenomenon to similar findings in shock lung and pulmonary embolism.

    Purpose:

    • To investigate the potential cause of transitory atelectasis in acute pneumonia.
    • To explore the relationship between reduced lung volume and surfactant system function.
    • To hypothesize a link between surfactant dysfunction and atelectasis in various acute lung conditions.

    Summary:

    • Reports on five acute pneumonia cases with transient, non-obstructive atelectasis.
    • Documents reduced lung volumes in these patients.

  • Suggests a potential surfactant system disorder as a unifying factor for atelectasis in pneumonia, shock lung, and pulmonary embolism.

    • Impact:

    • Highlights a potential novel mechanism for atelectasis in acute respiratory conditions.
    • Suggests surfactant dysfunction as a target for future research and therapeutic interventions.
    • Enhances understanding of the pathophysiology of acute lung injury and collapse.
