TY - SER TI - Balance nitrogenado en el paciente quirúrgico sometido a nutrición artificial: nuestra sitemática SN - 0210-5020 N1 - Este artículo se encuentra disponible en su edición impresa; Bibliografía: p. 18 N2 - The Nitrogen Balance (B.N.) is essential in nutritional techniques to demonstrate the effective protein-caloric performance of the subject subjected to Enteral or Patenteral Nutrition.

The most accurate method for this calculation is the Kjeldahl method, but it requires expensive and delicate equipment. Avoiding this problem we use a modification of the method of S. Dudrick. The calculation of nitrogen losses represents a reliable and simple method to elaborate the B.N. in the patient subjected to Artificial Nutrition ER -
