Abstract
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.
