The 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). ⋯ 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.

They are analyzed the problems which are present during placement of multiple-lumen subclavian catheters using the Seldinger technique, such as: the difficulty in anesthesia of the puncture area; failure in location of the vein; difficulties in advancement of the guide wire, the dilator or the catheter; catheter malposition; and accidental puncture of the subclavian artery, the pleura or the trachea; and also some potential solutions.
