Noninvasive ventilation in difficult endotracheal intubation: systematic and review analysis.

Overview

Noninvasive ventilation has been widely used in the management of acute respiratory failure in appropriate clinical settings. In addition to known benefit of alleviating the need for invasive mechanical ventilation, recent literature suggested its beneficial use in the process of endotracheal intubation. Search of the PubMed database and manual review of selected articles investigating the methods and outcomes of endotracheal intubation in difficult airway due to hypoxemic respiratory failure and the role of noninvasive ventilation in this process. Large randomized controlled studies focused on alternative approaches to endotracheal intubation in severe hypoxemic respiratory failure are largely missing but there are several retrospective cohort analysis and reports describing the novel technique describing the application of noninvasive ventilation during endotracheal intubation. Noninvasive ventilation can be used as an adjunct intervention that may maintain oxygenation and ventilation, prevent significant hemodynamic instability and provide a pneumatic stent to maintain upper airway patency, thus reducing the risks of intubation-related complications.
