[Bacteriologic control of total parenteral nutrition formulations at the Bellvitge Hospital].
Septic complications often lead to halting nutritional parenteral therapy. In general, the source of infection lies in the mixture, the connection and/or point of catheter insertion. The objective of this study is to show the need for bacteriological control throughout the parenteral nutrition process in order to assess the efficacy of the methods used, discover the source of infection and establish an in-house quality control. Different methods for bacteriological control of parenteral nutrition mixtures are studied and are compared with the method used at our hospital which is based on routine culture sampling after the mixture is prepared and before it is perfused, on repeating bacteriological control cultures and on performing bacteriological assessments of the catheter. In order to achieve this goal, 28.501 nutritional parenteral samples from 1,782 patients were studied. Only 185 (0.65%) samples were originally positive, and only 59 of them (0.21%) remained positive following a verification culture. Of the 6 culture-verified septic cases, 5 corresponded to Enterobacter cloacae and 1 to Klebsiella pneumoniae.
