[Catheter management in parenteral nutrition]

Following the appearance of Staphylococcus epidermidis positive hemocultures in four patients undergoing parenteral nutrition in different services, and after microbiological controls of the mixtures prepared by the Pharmacy Service in order to discard contamination during preparation, it was decided to assess the handling o catheters and central pathways by the Hospital Nursing Staff. A survey was carried out of 34 nurses, 17 each from the morning and evening shifts, from the floors with patients undergoing parenteral nutrition, representing 13.3% of all the nurses of those floors. There were five sections in the survey, with fifty-two questions referring to the introduction of catheters, change of dressing, care of the point of insertion, uses of the administrative pathway, change and handling of the parenteral nutrition bag, intravenous administration of medicines and parenteral nutrition, and withdrawal of the catheter. According to the results, 76% of central catheters are introduced in the operating theatre: once in place, the catheter is checked by X-ray to ensure that it is in the correct position, in all cases. There were major differences in the changing of dressings. The pathway for administration of the parenteral nutrition is used for a variety of functions. Medicines are administered in "Y" with the nutrient mixture, although their stability is not known. In changing the parenteral nutrition bag and the handling of the catheter, adequate sterilization measures were not taken.(ABSTRACT TRUNCATED AT 250 WORDS)
