The modified Evan's blue dye procedure fails to detect aspiration in the tracheostomized patient: Five case reports


The modified Evan's blue dye procedure (MEBD) is a method of performing tracheal suctioning of the patient through the tracheostomy tube after administration of color-contrasted food and liquid. The MEBD is done when radiographic or fiberoptic procedures are not available or practical. In 5 tracheostomized patients, the MEBD does not detect aspiration.
