hehady Posted November 30, 2006 Share Posted November 30, 2006 Do you routinely cover TPN solution? How? Link to comment Share on other sites More sharing options...
Stefan Johansson Posted December 3, 2006 Share Posted December 3, 2006 We don't cover the TPN-bags at all. (Do manufacturers of TPN constituents have different recommendations, as to whether their products are light-sensitive?) Link to comment Share on other sites More sharing options...
hehady Posted December 4, 2006 Author Share Posted December 4, 2006 A number of researchers have demonstarted that covering TPN solutions would decrease peroxide load. We have just finnished a RCT in our institution and we had similar reults. We are updating our guidelines and we are searching for other institutions guidelines Link to comment Share on other sites More sharing options...
Hans Joergen Posted December 4, 2006 Share Posted December 4, 2006 Some water-soluble vitamins (e.g. riboflavin’s) that are mixed with TPN (we use vaminolac) need to be protected from light. If you don’t, riboflavin will be reduced quite rapidly. Link to comment Share on other sites More sharing options...
Stefan Johansson Posted December 4, 2006 Share Posted December 4, 2006 Hmm, I will get in touch with our TPN group & the Pharmacy and see hear their opinion on why we don't cover the TPN. Link to comment Share on other sites More sharing options...
hehady Posted December 8, 2006 Author Share Posted December 8, 2006 Dear Stefan Lipids and multivitamines are particularliy involved in peroxides production on exposure to light. Using special bags or covering TPN solutions with alminum foil may be a good practice. Link to comment Share on other sites More sharing options...
brian777 Posted April 9, 2007 Share Posted April 9, 2007 yes, we cover all tpn's adult and neonatal. Link to comment Share on other sites More sharing options...
Guest nicurn2083 Posted May 14, 2007 Share Posted May 14, 2007 We use dark opaque brown bags to cover TPN in our NICU. They help to protect mutliple additives from photo-oxidation. Jennifer Tucker RN HCMC Minneapolis, MN Link to comment Share on other sites More sharing options...
Guest jwalden Posted August 17, 2007 Share Posted August 17, 2007 Yes, we use the amber plastic bags as well to cover the TPN. TPN arrives from Pharmacy in these bags, and once hung the amber bag is slipped over the TPN bag to keep it covered. Link to comment Share on other sites More sharing options...
satyen75 Posted August 31, 2007 Share Posted August 31, 2007 We have not been covering our TPN as fat soluble vitamins are not available in India. But such vitamins are known to produce peroxideson photooxidation. I will just like to ask how do You check for peroxides ? Is there a special test.
