INTRODUCTION: Intubation with a laryngeal tube (LT) is a recommended alternative to endotracheal intubation during @entity1442 ( @entity1442 ). LT insertion is easy; therefore, it may also be an alternative to bag-mask ventilation ( @entity1899 ) for untrained personnel performing @entity402 ( @entity402 ). Data from manikin studies support the influence of LT on @entity450 ( @entity450 ) during @entity1442 . METHODS: We performed a prospective, randomized manikin study using a two-rescuer model to compare the effects of ventilation using a LT and @entity1899 on @entity450 during @entity402 . @entity1 were trained in @entity1899 and were inexperienced in the use of a LT. RESULTS: There was no significant difference in total @entity450 with the use of a LT and @entity1899 (LT: mean 83.1        37.3  s; @entity1899 : mean 78.7        24.5  s; p   =   0.313), but we found significant differences in the progression of the scenario: in the @entity402 -scenario, the proportion of time spent performing chest compressions was higher when @entity1899 was used compared to when a LT was used. The quality of chest compressions and the ventilation rate did not differ significantly between the two groups. The mean tidal volume and mean minute volume were significantly larger with the use of a LT compared with the use of @entity1899 . CONCLUSIONS: In conclusion, in a two-rescuer @entity402 scenario, @entity450 is longer with the use of a LT (without prior training) than with the use of @entity1899 (with prior training). The probable reasons for this result are higher tidal volumes with the use of a LT leading to longer interruptions without chest compressions.
