A placebo suspension which is made by the Investigational Drug Service (IDS) by adding the appropriate dye coloring to normal saline so that the appearance is identical to the indomethacin suspension.

Following instillation of the placebo suspension, the catheter is flushed with 5 cc of normal saline.
