Hypothermia should also have been considered to be a predictor of adverse perioperative cardiac events.

LMA-PTM. It is not a single-use LMA-PTM because substantial details are designed and constructed in a different way to overcome weaknesses of other LMAsTM, as the producers of the LMA-STM promote their device. The LMA-STM’s clinical performance can only be evaluated in clinical trials. First published comparisons with a reasonable sample size between the LMA-PTM and LMA-STM showed clinically important differences in the seal pressure between both devices. We affirm our statement that acute airway obstruction of LMAsTM can occur at any time, and backup strategies for the failure of the backup device LMATM have to be considered.
