![]() ![]() Assessment of potential precipitation was performed by subvisual particle counting, visual examinations and measurements of turbidity and pH. Drug : TPN ratios were estimated from a wide range of age and weight classes, and the most extreme mixing ratios (drug > TPN, TPN > drug) in addition to 1 + 1 were chosen. Two three-in-one TPN admixtures (Olimel N5E and Numeta G16E) used for children of different age groups were tested with ten drugs (ampicillin, ceftazidime, clindamycin, dexamethasone, fluconazole, fosphenytoin, furosemide, metronidazole, ondansetron and paracetamol). The purpose of this study was to obtain Y-site compatibility data on intravenous drugs and total parenteral nutrition (TPN) relevant for children. And use a BIOPATCH, antimicrobial disc as part of the routine sterile drsg change procedure.Infusion of precipitate or destabilized emulsion can be harmful. Change you needleless injection caps daily, as well as the IV bag and IV tubing. Care for it well, and flush it well between the infusions and reconnections. In these instances when one has no OTHER option but this SL catheter. But, maintaining good techniques with hub cleaning and mantenance will decrease microbial formation/contamination. I can image that those neonates don't have vessels large enough for anything but a Single Lumen 1.9/2 French IV catheter, however, that does cause other issues, like an increase concern for precipitates and infection.īiofilm (organisms which collect inside the IV catheter and create a slime covering) inside the IV catheter will be increased with the high glucose infusion, and it's difficult to prevent this completely. If you are flushing, and many meds ARE compatible with our TPN, there shouldn't be a problem. ![]() I have not seen one clot off for this reason above. therefore you may get particulate adhering to the walls of the lumen of the PICC and the next med that you give is not compatible with the first one that you gave and reacts causing precipitation in the lumenĬan I ask where this information is from? In NICU, we almost exclusively use single piccs and we don't have a choice but to use it for TPn and meds. And if the TPN runs out, before your next bag is to you, the standard is to hang a Liter of D10, not D5W, and hang it to run at the same rate as the TPN, not KVO.Īlso because of the high dextrose content the lining of the lumen of the PICC becomes very viscous. No blood draws, or other IV medication should be piggybacked into this line. Ideally, the lumen used for TPN should be TPN dedicated only. ![]() So one should be concerned with infection control issues, but also incompatibilities. Yes that is "heavy duty" sugar, and yes, bacterial love it. If your TPN runs out or expires before the next bag is available the recommendation is to run a bag of 5% dextrose TKVO and maintain the sterility of the giving set.Īctually, most of the time, the dextrose in TPN is 50 to 70%. Once a lumen of a PICC has been used for TPN at all it cannot be used for anything else. So it is not ideal to stop and start TPN. therefore you may get particulate adhering to the walls of the lumen of the PICC and the next med that you give is not compatible with the first one that you gave and reacts causing precipitation in the lumen. Every time that the line is disconnected opportunist bacteria will get in.Īlso because of the high dextrose content the lining of the lumen of the PICC becomes very viscous. The problem with this is that it is a great media for bacterial growth. TPN has a high level of dextrose anywhere between 11-25%. ![]()
