It is strange how the process differs from hospital to hospital. I was given 8 scrub gizmos to use; one for upper torso and one for lower torso to be used for the four days preceding my surgery. I also received a mouthwash to be taken after each meal on Sunday before I go in for the surgery. I will be 69 next month and other than a gall bladder operation, this will be a first for me regarding surgery. Like you I have confidence in my surgeon and the Ottawa University Heart Institute. My Surgeon replaced a valve for my Aunt just this January past and she is older than I am and doing well, although she did not need the double bypass that I will also get. Good thoughts to you also for a speeding recovery.Gord
