Abstract
Subject selection for the study was carried out in accordance with the non-probabilistic intentional-type method and on the basis of inclusion and exclusion criteria.
The most outstanding results were as follows: 87% of the catheters were categorised as "easily managed" and 12.1% as "very easily managed" in accordance with pre-established observational guidelines that included 20 items relating to the asepsis and antisepsis criteria, dressing change frequency every 48 hours, change of the flask-bag, and complete protocol to be followed in Total Parenteral Nutrition (TPN), as well as the use of devices such as flow rate regulators, double-channel lines and endovenous filters.
65% of the catheters were inserted into the subclavian vein while 35% were inserted into the internal jugular vein. Catheter-associated infections reached the 35% mark while bacterial catheter-associated infections reached 22.5%. The predominant germs found were staphylococcus aureus (85.7%) and candida albicans (14.3%).
The most relevant conclusions were that nurses working at the "Artificial Nutritional Support Unit" apply asepsis and antisepsis measures before, during and after the procedure in patients with a central line for TPN purposes. These measures did not hinder significantly the results of catheter tip positive cultures. However, the negative results show high percentages of catheter-associated infections, which comes to demonstrate that the nursing management is not a causal factor of great magnitude. As insufficient evidence exists, the presented hypothesis that nursing management is directly related to the incidence of catheter-associated infections (CAIs) is therefore rejected, and that both variabilities behave independently from each other.
