[DYSPHAGIA] Blue dye.

[LOBSTERPAM@aol.com (LOBSTERPAM@aol.com)]

Irene, 

As the blue dye reacts with the colors of the existing secretions, making 
them greenish, would not red dye similarly react, and therefore "color" the 
possible interpretations one might make bedside?  How would one differentiate 
a potential color interaction from red dye from one that might be made from 
blood?  Blood comes in many hues; I've seen this in suctioning; it's my 
reason for using blue.  For blood, brick to crimson, at the very least.   
Blue's not perfect; but I've not been convinced that using red is either.  I 
have never expected a patient to bleed more green, unless (horors) his name 
was Spock.
