Abstract
A variety of catheters, stylets, and obturators have been used to assist with problems in airway management. Obturators specifically designed for airway use are now available in different sizes. The pediatric-size obturators (2.2 mm diameter) can be placed into the airways of most patients without apparent respiratory impairment. Use of these obturators to preserve a path to the airway is described in cases of tracheostomy and tentative extubation. The advantages and disadvantages inherent in the use of such obturators are described.
