In vitro analysis of overall particulate contamination exposure during multidrug IV therapy: impact of infusion sets
Abstract
Drug incompatibilities, recognizable through precipitate, may have clinical consequences for patients, especially during multidrug IV therapies, where vancomycin and piperacillin are present. Drug concentration and infusion set influence the overall particulate contamination of pediatric infusion protocols. The use of multi-lumen infusion sets could prevent such incompatibilities. Our goal was to define and assess a new way to infuse these drugs during leukemia treatment in children. This in vitro study focused on a pediatric multidrug protocol for patients diagnosed with lymphoblastic leukemia and receiving allogeneic transplantation. Different vancomycin concentrations were tested to infuse incompatible drugs simultaneously without any particle formation (optimized multidrug protocol). A dynamic particle count test was used over 24 hr to evaluate the overall particulate contamination of our standard and optimized multidrug protocols, using both a standard and a multi-lumen infusion set. No visible particles were detected on a decreased vancomycin concentration compared to the standard dose. For the optimized multidrug protocol, the use of a multi-lumen infusion set reduced overall particulate contamination by 68%, compared to...Continue Reading

Blood And Marrow Transplantation
The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
