Size of traumatic pneumothorax on initial chest x-ray is independently associated with failed observation in children
Topic overview
Retrospective study of 313 pediatric trauma patients found that pneumothorax size ≥12.5% on initial chest x-ray (measured by Collins method) independently predicted failure of observation without tube thoracostomy. Findings suggest smaller traumatic pneumothoraces can be safely observed, potentially avoiding prophylactic chest tube placement in select pediatric patients.
Key takeaways
- Traumatic pneumothorax ≥12.5% on initial chest x-ray (Collins method) independently predicts failed observation in children.
- Children with tPTX <12.5% can be safely observed without prophylactic tube thoracostomy in most cases.
- Failed observation occurred in 13.5% of children managed without initial tube thoracostomy.
- Hypotension, hemopneumothorax, and supplemental oxygen use were more common in failed observation but not independent predictors.
- The Collins volumetric method on chest x-ray provides a quantifiable threshold (12.5%) to guide tube thoracostomy decisions.
