AbstractThe objective of the study is, on one hand, to determine the etiology and the clinical implications as a function of the isolated germ, of central venous catheterization in patients with parenteral nutrition in our hospital, and on the other hand, to determine which factors are associated with the selection of germs of central venous catheterization in parenteral nutrition. For this we included venous catheters, colonized for 5 years, and with a study of the different segments (connection, insertion point, and tip). As a function of the appearance of associated clinical symptoms, of the results of the blood culture, and of the clinical evolution of the patient, the variables which determine the level of pathogenicity of the different groups of germs in the central venous catheterization, are defined; for the study of the factors associated with the selection of the different groups of germs, 8 variables were chosen. The data obtained are statistically treated, and the results are considered to be significant if p < 0.05. The understanding of the different factors associated with the selection of germs, and the level of clinical pathogenesis of the different groups, allows a better level of the clinical action in the prevention of the infection associated with the catheter.
