Raina you said they last 6 to 10 hours. If you are on first shift you could pass them on to someone and them to someone. Recycle, Recycle, Recycle.When I cut off an arm of a sweatshirt that I plan on wearing to dialysis, I keep the sleeve to put over my lower arm to keep warm. My fistula is in my upper left arm.
Homemade rice bags work too... and every dialysis center I been too, has a microwave, so they can easily throw it in for a few minutes when it needs reheating. They stay warm awhile, and feel good.
A now-deceased fellow patient told me about this and hooked me up with my first fix and its really helped me. I used to be really, really cold during treatments, especailly my hands, and quite miserable. They have these hand-warmers you can buy during the winter at 711 and Walgreens. They are 2 for 99c. In the winter you can only get them at outdoor stores and they jack up the price to 2/2.50 (for the exact same thing!) If you really like them you can do like I did and get a case of 240 pairs for $156. http://industrialsavings.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=1100-10R_CASEAnywhoo they work on some kind of a chemical reaction when they are exposed to air and shaken lightly and get warm in about 15 minutes, REALLY warm in about a half hour. They last for 6-10 hours. Because they get allittle too hot sometimes I like to put them between small and large gloves. My hands haven't turned blue since. Sometimes if the rest of me is cold I throw one in my blankets.I don't see why the centers don't buy these for us, I can get them wholesale for $0.31 so they can get them much cheaper than running to get gloves full of warm water. A few words of caution.. it says not to use them if you are diabetic. I think this is because they can get a bit too hot and burn you, I have two permanent scars on my wrist from tying them to bone spurs. It also says not to use them anywhere portable oxygen is used.. I didn't read this until I'd been using them in dialysis (with a half dozen people on oxygen) and have not yet, myself, caused any explosions.Thats prolly why the centers wont buy them, laibility. Anywhoo I hope this helps someone. It sure helped me!
