title: [Cuffed pediatric endotracheal tubes].
abstract: BACKGROUND
  The goal of this investigation was to evaluate the details of cuffed pediatric endotracheal tubes (PCETTs, I.D. 3.0-6.0 mm) available in Japan.
  
  
  METHODS
  Following dimensions of all PCETTs were measured; the distance from the tube tip to the distal/proximal border of cuff, cuff length, cuff volume and cuff diameter at 20 cmH2O cuff pressure, outer diameter and length of tubes, the distance from tube tip to the distal border of depth markings, length and the number of depth markings, calculated cross sectional area of the Murphy eyes, and the number of the Murphy eyes.
  
  
  RESULTS
  A total of 73 PCETTs, including 20 brands from 10 manufacturers, were investigated, in which 82.2% of PCETTs are larger than I. D. 5.0. There are significant differences in the distance from tube tip to the distal/proximal border of the cuff, and the cuff length at 20 cmH2O cuff pressure for a given I.D. Some tubes have no depth markings, others have multiple ones, and depth markings are positioned differently. Eighty-three point six % of PCETTs have one Murphy eye.
  
  
  CONCLUSIONS
  There is no uniformity in the details of PCETTs available in Japan. The details of PCETTs including cuff design and depth marking should be updated.
