Retrospective analysis of statewide out-of-hospital cardiac arrests on over 1000 patients receiving either passive ventilation or bag-valve-mask ventilation treatment by paramedics. Adjusted neurologically intact survival between ventilation techniques was the main results category compared. Passive ventilation proved more successful under the terms used.

This letter is a response to a small LMA Supreme® study. The authors say that they have been using the device in patients having nasopharyngeal surgery as it protects the airway from any bleeding and has a gastric channel to remove any blood in the stomach. However, they have reviewed recent research and believe that their current practice may change. In previous studies, the i-gel® has performed as well as the LMA Supreme® even when all i-gel® patients have been given a size 4 device and the LMA Supreme® has been sized correctly. Gastric tube placement in the two devices and the LMA Proseal® is also comparable. The authors are considering the use of the i-gel® or ProSealTM instead of the SupremeTM.
