| Popis: | Neutron activation analysis and skinfold measurement were used to measure body composition of 12 surgical patients before and after a 2 week course of intravenous nutrition with glucose as the source of energy. Pre-illness body composition was predicted using regression equations which considered age, sex and height. At the onset of intravenous nutrition, mean total body potassium was 1857 mmol or 30% less than predicted. Other components of body cell mass which included body nitrogen, were reduced by 15–20%. Although 60% of the deficit of potassium could be explained by depletion of body protein and glycogen, 40% probably reflected a subnormal intracellular potassium concentration. Intravenous nutrition with dextrose and amino acids resulted in a gain of body potassium of 210 ± 44 mmol (p |
