title: [In vitro evaluation of lubrication properties of a suction catheter].
abstract: BACKGROUND
  Lubrication is an important factor for passage of a suction catheter through a tracheal tube. This study was carried out to evaluate the effects of lubricants on resistance against removal of a suction catheter from a tracheal tube in an experimental setting.
  
  
  METHODS
  A tracheal tube (I.D. of 7.5mm) was inserted into a mannequin, and the resistance against removal of a suction catheter from the tube was measured.
  
  
  RESULTS
  Lubrication was improved by using a lubricant (lidocaine jelly or KY jelly), but there was no difference between the effects of the two lubricants. The use of water as lubricant markedly decreased lubrication. Differences in lubrication depending on the type of tracheal tube used, probably due to differences in coating, were also found.
  
  
  CONCLUSIONS
  The use of water as a lubricant is not recommended for tracheal suction.
