Utilization of Energy Substrate in Critically Ill Patients
Total parenteral nutrition (TPN) is a new medical discipline whose development has been spectacular over the past twenty-five years. Technical and septic complications related to long-term keeping of intravenous catheters have represented for many years the major risks of parenteral feeding. These problems have been progressively solved by the availability of improved equipment, the creation of nursing teams specialized in the care of these patients and the respect of very strict guidelines. The progresses in the technical aspects of parenteral nutrition are very similar to those reported for haemodialysis.
