Invention and Pilot Study of the Efficacy and Safety of the SUPRAtube Device in Continuous Supraglottic Aspiration for Intubated and Mechanically Ventilated Patients.

ABSTRACT:

Background

Bronchoaspiration of content that accumulates in the supraglottic area (eg, saliva, gastroesophageal reflux) is a risk factor for ventilator-associated pneumonia. A continuous supraglottic suction system may decrease the risk of bronchoaspiration in these patients.

Objective

(1) Constructing a conceptual model and functional prototype of a continuous supraglottic suction device for use in humans; (2) defining functional characteristics in ex vivo swine head models; and (3) evaluating its efficacy and safety in mechanically ventilated patients.

Methods

Study conducted in three phases. First phase: definition of distances and diameters of the triangle determined by dental arch, posterior oropharynx and vallecula, and diameter of the oropharynx in axial projec
