Complete parenteral nutrition by means of continuous intravenous drip into large veins, over a long period, has already shown itself to be of therapeutic use in the field of pediatrics. While the nutritional-physiological aspect of this therapeutic method is clear -- it depends on an accurate and sufficient supply of water, salts, glucose, amino-acids, triglycerides and essential fatty acids, vitamins and trace elements -- in practice it presents difficulties which though often serious are not insurmountable. Especially are to cite the septic complications, which are nearly imperceptible during their development. They are only to accept in view of the often almost hopeless condition of the child, who would be lost without complete parenteral feeding. Similar problems arise through metabolic complications which are caused non rarely only by insufficient dosages and lack of careful supervision but it is generally possible to correct these at an early stage. Complete parenteral nutrition must be exactly indicated. It is indeed a great therapeutic help, particularly when over a longer period -- at least a week or longer -- oral nutrition is impossible or insufficient. Practicall experiences will be reported. A retrospective assessment of 50 cases has shown the tendency (through taking too much care?) to hold the quantity of liquids and supply of calories too short and to administer too much carbohydrates and too little fat.
