title: Evaluation of a flexible fiberoptic catheter in confirming endotracheal tube placement in the intensive care unit.
abstract: We evaluated the use of an inexpensive 2.2-mm fiberoptic catheter (FOC) to assess endotracheal tube (ETT) placement in 22 critically ill adult patients.
  
  
  METHODS
  The distance between the carina and the distal tip of the ETT was measured under direct visualization with the FOC and compared to the corresponding measurement obtained from concomitant chest radiographs.
  
  
  RESULTS
  There was a significant linear correlation between measurements made by the two methods (r = 0.97, P less than 0.0001), and all FOC measurements were within 1 cm of the corresponding radiograph measurements. No complications or significant changes occurred in peak airway pressure, tidal volume, respiratory rate, or heart rate. The procedure usually was performed in less than 1 minute. Cost analysis revealed the possibility of major savings when the FOC is used instead of portable chest radiography.
  
  
  CONCLUSIONS
  We conclude that documentation of endotracheal tube placement by means of a fiberoptic catheter is rapid, accurate, safe, and cost-effective.
