Official Title: Aspiration of Subglottic Secretions in Intubated Critically Ill Patients Using Hi-Lo Evac Endotracheal Tube: Correlation Between Tube Size and Incidence of Suction Lumen Dysfunction

Further study details as provided by University Hospital, Alexandroupolis:

Estimated Enrollment: 60
Study Start Date: January 2007
Detailed Description:

In mechanically ventilated patients, aspiration of subglottic secretions is a widely used intervention for prevention of ventilator-associated pneumonia. Using Hi–Lo® Evac endotracheal tube (Hi-Lo Evac; Mallinckrodt; Athlone, Ireland), dysfunction of suction lumen and subsequent failure to aspirate the subglottic secretions is not uncommon. The objective of this prospective observational study is to determine the causes and the incidence of suction lumen dysfunction of Evac endotracheal tube.
