Purpose: The 2010 American Heart Association (AHA) guidelines propose the use of a Laryngeal Mask (LMA) as an alternative to tracheal intubation for Cardiopulmonary Resuscitation (CPR). Use of a ProSealTM laryngeal mask, bent 90 degrees by an intubating stylet, has been reported to yield definite insertion. We compared speed and success of insertion between the styleted LMA (ProSeal-90D) and the conventional LMA (ProSeal-N).

Methods: A total of 20 novice doctors in our Department of Anesthesia performed insertion of both the ProSeal-N and ProSeal-90D on a manikin, with and without chest compression. Insertion times and successful insertion rate with first attempt were recorded.

Results: Chest compression decreased the ventilation success rate significantly for the ProSeal-N, but did not affect the results for the ProSeal-90D. Moreover, when chest compression was performed, ventilation success rate was significantly higher for ProSeal-90D than the ProSeal-N. Insertion time was lengthened by chest compression for ProSeal-N, but not for ProSeal-90D.

Conclusions: In simulated resuscitation, rapid successful placement was more frequent with the ProSeal-90D than the ProSeal-N during chest compressions.
