Welcome to the site, wei! Glad you joined us.
I don't work with dialysis patients per se (usually outside of the dialysis unit), but know what you are talking about. Feel free to discuss away. The Staff Nurse Section is designed for that!
How long have you been a nurse, just to be curious? Perhaps you can share some dialysis hints, tips, and info. in our Dialysis/Renal Nursing Forum. (Look under the Specialty Heading)
