    Abstract:
    An evaluation is made of liver malfunctions in patients receiving TPN over a period of > or = 15 days between 1989 and 1991. Use was made of the monitoring records on patients undergoing TPN and, subsequently, of clinical records, with analysis of diagnoses and type of intervention, the biochemical parameters (SGOT, SGPT, GGT, FA, LDH, and total and direct bilirubin), and the type and degree of malnutrition, nutritional backup, associated medication, etc. A group of patients was excluded from the study on the basis of the following criteria: liver-biliary disease, cardiac insufficiency, liver metastasis, sepsis, kidney insufficiency and hepatotoxic drugs. Of 237 patients, 75 (31.64%) had liver alterations: following application of the exclusion criteria, 24 patients (10.12%) were taken with liver alterations attributable to the TPN. Macro- and micronutrients were included in the TPN. We found no relation between the kcal/kg of weight, nor with the quantity of glucose and fats nor of nitrogen, calculated according to individual requirements: they remained within the limits established. No serious case of cholestatic jaundice was encountered. Moderate to severe malnutrition was found in 50% of patients, so that this must be treated as a risk factor. GGT is the first enzyme to alter; this occurred in the largest proportion of patients (91.66%), followed by SGPT. FA and GOT are altered in the same percentage of patients. Biochemical parameter monitoring is essential in patients undergoing TPN, not only for appraisal of the nutritional state but also to prevent or correct potential serious metabolic complications.
