Using a laryngeal tube suction-device ( LTS-D ) reduces the " no flow time " in a single rescuer manikin study . BACKGROUND In 2005 , the European Resuscitation Council and the American Heart Association published new guidelines for Advanced Life Support . One of the points was to reduce the time without chest compressions in the first phase of cardiac arrest . OBJECTIVE We evaluated in a manikin model whether using the single-use laryngeal tube with suction option ( LTS-D ) instead of endotracheal intubation ( ET ) and bag-mask-valve ventilation ( BMV ) for emergency airway management could reduce the " no-flow time " ( NFT ) . The NFT is defined as the time during resuscitation when no chest compressions take place . METHODS A randomized , prospective study was undertaken with 150 volunteers who performed management of a standardized simulated cardiac arrest in a manikin . Every participant was randomized to one of three different airway management groups ( LTS-D vs . ET vs. BMV ) . RESULTS The LTS-D was inserted significantly faster than the ET tube ( 15 s vs. 44 s , respectively , p < 0.01 ) . During the cardiac arrest simulation , establishing and performing ventilation took an average of 57 s with the LTS-D compared to 116 s with ET and 111 s with the BMV . Using the LTS-D significantly reduced NFT compared to ET and the BMV ( 125 s vs. 207 s vs. 160 s ; p < 0.01 ) . CONCLUSIONS In our manikin study , NFT was reduced significantly when the LTS-D was used when compared to ET and BMV . The results of our manikin study suggest that for personnel not experienced in tracheal intubation , the LTS-D offers a good alternative to ET and BMV to manage the airway during resuscitation , and to avoid the failure to achieve tracheal intubation with the ET , and the failure to achieve adequate ventilation with the BMV .
