[Experimental questions about parenteral nutrition].
In a synopsis theoretical and experimental problems of the parenteral nutrition are discussed. The infusional phlebitis and thrombose, the technique of exact dosage of infusion fluids, the balance of nitrogen utilization and questions of the essential and unspecifical nitrogen sources, the energy requirement and the carbohydrate utilization, the dynamique of insulin secretion and possibilities of energy preparation by lipid components are especially mentioned. Finally a general conception of parenteral nutrition inserted in cited and discussed results is developed which is proceeding from the thesis, that the nitrogen requirement related to the body weight is determinining the requirements of energy, potassium and water. The limiting factors of parenteral nutrition are the maximal turnover of substrates and the osmotical excretion capacity in the homoiostatic regulation.
