intercostal retractions
Visible inward pulling of the muscles between the ribs during inspiration, indicating increased work of breathing.
Full Definition
Intercostal retractions occur when the muscles between the ribs are pulled inward during inspiration, creating visible indentations in the chest wall. This clinical sign indicates increased work of breathing and respiratory distress in pediatric patients. The phenomenon results from increased negative pressure generated during inspiration when airways are obstructed or lung compliance is reduced. Intercostal retractions may be accompanied by subcostal, suprasternal, or supraclavicular retractions, with the severity and location providing information about the degree of respiratory compromise.
Usage
Usage note: Document the severity (mild, moderate, severe) and location of retractions for comprehensive assessment.
