[Value of post-operative parenteral nutrition as shown by various plasma protein measurements (author's transl)].

A significant improvement in urea nitrogen and plasma protein metabolism during the first 10 days after abdominal surgery was obtained in 24 patients who received parenteral carbohydrates combined with essential amino acids and histidine. A control group of 15 patients who only received water and electrolyte balance in the post-operative phase showed significantly worse results. The observation that immunoglobulins (IgG) and complement components (C1q, C3 activator) recovered more quickly from the stress of surgery under the influence of parenteral nutrition seems to be particularly important.
