title: The novel intubating laryngeal tube (iLTS-D) is comparable to the intubating laryngeal mask (Fastrach) - a prospective randomised manikin study.
abstract: BACKGROUND
  Supraglottic devices are helpful for inexperienced providers who perform ventilation in emergency situations. Most supraglottic devices do not allow secondary tracheal intubation through the device. The novel intubating laryngeal tube (iLTS-D) and the intubating laryngeal mask (Fastrach) are devices that offer supraglottic ventilation and secondary tracheal intubation.
  
  
  METHODS
  We evaluated the novel iLTS-D and compared it to the established Fastrach using a manikin-based study. Participants used both devices in a randomised order. The participants conducted four consecutive trials on a manikin. One trial was composed of the following procedures. First, participants ventilated the manikin using either iLTS-D or Fastrach. 'Time to ventilation', success rates and number of attempts were recorded for the supraglottic device. Second, participants intubated the manikin through the previously inserted supraglottic device. 'Time to tracheal ventilation', success rate and tube localisation were recorded. The primary endpoint was the results of the final fourth trial, which mirrored the standardised training of trials 1, 2 and 3.
  
  
  RESULTS
  A total of 64 participants were enrolled. All of the participants successfully inserted both devices on their first attempt in trial 4. Fastrach was applied 1 s faster in trial 4 than the iLTS-D (median 'time to ventilation' Fastrach: 13.5 s., iLTS-D: 14.5 s., p = 0.04). All participants successfully intubated through both devices in trial 4. There was no difference in 'time to tracheal ventilation' by tracheal intubation between either device (median 'time to tracheal ventilation': Fastrach: 14.0 s., iLTS-D: 14.0 s., p = 0.16).
  
  
  CONCLUSIONS
  The iLTS-D performed similarly to the ILMA in insertion and intubation times in a manikin setting.
