Great question.... I am a dialysis nurse, and have been for many, many years. I am an acute dialysis nurse, and I wish more nurses were concerned about medication administration as it relates to hemodialysis. Reading the responses to your posting, they are right on the money. That pocket guide that has been mentioned is readily available and most dialysis nurses carry one with them or have one easily accessable. We have a chart in our medication room that covers a huge portion of the wall that has most frequent medications listed. So, if your dialysis nurses aren't being helpful, it isn't because the information isn't available. (dialysis nurses can be a little obstinant, in my opnion - I think many of them go into dialysis because they don't play well with other!) As a "rule", we do not administer drugs during hemodialysis with the exception of dialysis meds (epogen, zemplar, iron, etc...), certain antibiotics, and prn medications for pain/anxiety.
One reply to your post mentioned bringing food trays to the dialysis unit. This should not be an issue. I recently researched just this subject, and conducted a very throrough literature review. All of the studies that I found were 100% against patients receiving food during dialysis... for various reasons. First and most important, postprandial hypotention. If there is food in the gut, there is diversion of blood flow to aid in digestion. This shunting of blood can cause a decrease in blood pressure. Another reason follows that same reasoning... with the blood shunting/diversion to the gut, the dialysis clearances are effected (i.e., less efficient hemodialysis).
