title: [Comparison of the Intracuff Pressure Increase by Upper Gastrointestinal Endoscope Insertion in TaperGuard Cuffed Tube and High-volume Low Pressure Cuffed Tracheal Tube: A Porcine Larynx Model Study].
abstract: BACKGROUND
  The purpose of this study was to compare the upper gastrointestinal endoscope (UGE) insertion-mediated cuff pressure increase between a tracheal tube with a tapered cuff (Taper) and or conventional high volume low pressure cuff (HVLP) utilizing a porcine larynx model.
  
  
  METHODS
  The automated cuff pressure was adjusted to 10, 20, and 30 cmH2O. The Taper and HVLP cuff pressure increases by UGE insertion were measured.
  
  
  RESULTS
  Significant cuff pressure increase was observed by UGE insertion regardless of initial cuff pressure. The cuff pressure of the Taper was significantly lower than that of the HVLP by UGE insertion.
  
  
  CONCLUSIONS
  These findings suggest that the Taper may be more effective than the HVLP in preventing tracheal tube cuff increase by UGE insertion.
