Influence of Neuromuscular Block on Mask Ventilation

Influence of a Neuromuscular Block on Face Mask Ventilation Conditions During Induction of Anaesthesia

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.

Inclusion Criteria:

• Patients with risk factors for difficult face mask ventilation
• Patients scheduled for general anaesthesia with endotracheal intubation

Exclusion Criteria:

• Increased Risk for pulmonary aspiration
• scheduled for awake fiberoptic intubation
• pregnancy
