Hydroelectrolytic and infectious complications in one year of parenteral nutrition in critical care

Abstract Objective Parenteral nutrition consists of the intravenous administration of macronutrients, micronutrients and electrolytes. Our objectives were to evaluate the biochemical alterations during the first ten days of initiation and to quantify the bacteremia related to the central venous catheter during the administration of parenteral nutrition. Material and methods Retrospective study of incidence and prevalence. We included 51 patients who started intravenous nutritional support therapy at Critical Care. We intend to know the infectious complications of the central line associated with parenteral nutrition, to evaluate the most frequent hydroelectrolytic complications of parenteral nutrition, and to identify minimum control points in the detection of hydroelectrolytic alterations. Results Statistically significant daily variations were found for glucose, magnesium, potassium and creatinine, and bordering on the statistical significance for albumin and phosphate, the alterations occurring between the second and third days fundamentally. Hypoalbuminemia and hypocalcemia were very frequent. GGT was the liver enzyme that increased more frequently. The infection rate was 14.86 per 1000 days of central venous catheter. Conclusions We found daily variations in glucose, potassium and magnesium, as well as a decrease in creatinine. We emphasize the frequency of hypoalbuminemia, hypocalcemia and elevation of GGT. The most important variations occurred between the second and third day, highlighting the precocity of potassium alteration and the peak of glycemia. The rate of infection related to the central venous catheter in patients with parenteral nutrition was high.
