ABSTRACT
Indigo carmine is a blue dye that is widely applied to localise ureteral orifices. It is generally believed to be a safe, biologically inert substance, and hypotensive reactions are extremely rare. However, we experienced three cases of indigo carmine-induced hypotension within a period of two weeks.

Keywords: hypotension, indigotindisulfonate sodium
