title: Left double-lumen tube with or without a carinal hook: A randomised controlled trial.
abstract: BACKGROUND
  Left double-lumen tracheal tubes (DLTs), with or without a hook to engage the carina, remain the standard device for lung isolation during anaesthesia.
  
  
  OBJECTIVE
  The purpose of the study was to compare these DLTs with and without a hook.
  
  
  METHODS
  A randomised, controlled, single-blinded study.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  One hundred and eighty-four patients undergoing lung resection.
  
  
  METHODS
  Time required to position the tube from the introduction of the tube into the mouth to confirmation of correct placement in the supine position.
  
  
  RESULTS
  Baseline characteristics were well balanced between the groups. Time to place DLTs was similar in both groups: median (interquartile range, IQR) 81.0 (50.0 to 146.2) s for DLTs without a hook and 67.5 s (45.0 to 138.7) for DLTs with a hook (P = 0.43). The incidence of adequate position at the first attempt was 68.5% in the No hook group and 69.6% in the Hook group (P = 0.95). Patients in both groups suffered similar incidences of sore throat at day 0 and day 1 (P = 0.80 and P = 0.20, respectively). No major lesion of the vocal cords or tracheobronchial tree was discovered and the incidence of minor lesions was similar in both groups.
  
  
  CONCLUSIONS
  When a DLT is used, the presence of a carinal hook gives neither advantage nor added complications.
