Hi Kim49, Thanks for your 2/17/11 reply about your experiences as a dialysis nurse on Dialysis at Sea Cruises. I was looking for some sort of review about what I was getting myself into, as the nephrologist for a 9/3/17, last minute commitment for a 7 day NJ-Bermuda-NJ Celebrity Summit cruise. Yours was the best review I could find. Of course, I'd love to know what it's like from the nephrologist's perspective. But, as any honest nephrologist would tell you, it's the nurses, God Bless Them!, who do the real work, and we, nephrologists, would be totally lost without them. Naturally, I'm curious about the availability of labs, the ability to do extra runs for over hydration, EKG availability for unexpected arrhythmia, Kayexalate, emergency drugs, and special diets for the patients. I know that many of the patients I've cared for in a long, long career, practice denial, and I must readjust my concept of my role as simply a caretaker, just to get them through a week of vacation and return them unscathed to their regular environment. Thank you for your comment.
