![]() ![]() In 17 of these (43%), it was attributed to blockage of the subglottic suction port by suctioned tracheal mucosa.Įvacuation of subglottic secretions using the Evac ETT is often ineffective due to prolapse of tracheal mucosa into the subglottic suction port. However, using the Hi-Lo Evac endotracheal tube (Hi-Lo Evac Mallinckrodt Athlone, Ireland) (Evac ETT), dysfunction of the suction lumen and subsequent failure to aspirate the subglottic secretions are common. In all cases for which dysfunction of the suction lumen was observed, the subglottic suction port was examined visually using a flexible bronchoscope.ĭysfunction of the suction lumen occurred in 19 of 40 patients (48%). Abstract Background: Aspiration of subglottic secretions is a widely used intervention for prevention of ventilator-associated pneumonia. We studied 40 adult patients intubated with the Evac ETT. Our objective in this study was to determine the causes of suction lumen dysfunction experienced with the Evac ETT. Incorporates a taper-shaped cuff that reduces microaspiration by an average of 90 compared to the MallinckrodtÖ Hi-Lo tracheal tube. OVERSTOCK SALE Shop IV Products, Surgical Supplies & Much More.
