The bacterial colonization of devices and especially central venous catheter (CVC) tips has an impact on morbidity and mortality, high associated costs, and prolonged hospital stay. The aim was to determine the biological behavior of biofilm formation in central venous catheters for total parenteral nutrition (TPN) with or without intravenous therapy. Descriptive, cross-sectional, prospective, non-random observational case study. The study population was 54 central venous catheter tips from medicine, surgery, general intensive care unit wards for 21 months and 20 days, with the Maki technique (MT) and scanning electron microscopy techniques (SEM). 18/54 were found positive with the MT and 54/54 positive from the same samples with the SEM. The MT had 36/54 (66.66%) false negative. Of 24 CVCs used for intravenous therapy (not including TPN), 16 CVCs were culture-negative, 6 CVCs were culture-positive, and 2 CVCs were culturenegative. Of the CVCs employed for TPN, 4 had a negative result, 2 had a positive result, and 28 had no result with TM. The analysis with the SEM shows the bacterial presence of biofilms on the intraluminal surface of all the catheters studied. The prevalence of bacterial colonization of CVC tips has been evidenced in more than half of the catheter tips using TM, but the biofilm formation was demonstrated in all the catheters studied by scanning electron microscopy.
