Influence of Neuromuscular Block on Mask Ventilation

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01849211
Recruitment Status : Completed
First Posted : May 8, 2013
Last Update Posted : February 21, 2020

Brief Summary:
Difficult mask ventilation might lead to a life-threatening situation, if endotracheal intubation is also impossible and neuromuscular blocking agents (NMBA) inhibit spontaneous ventilation. However, controversies exist if NMBA improve or impede face mask ventilation. Therefore, the effect of NMBAs on mask ventilation is assessed in patients with predictors for difficult face mask ventilation.
