Comparative StudyThe influence of preoperative total parenteral nutrition upon morbidity and mortality.
This study was done to examine the criteria for determining the adequacy of preoperative total parenteral nutrition (TPN). We hypothesized that an important criterion for adequate preoperative nutrition should be a contraction of the expanded extracellular fluid compartment known to occur in malnourished patients undergoing surgical treatment. Clinical evidence of this included a rise in the serum albumin level and weight loss. ⋯ The complication rate in the three groups was 4.3 per cent for those in group 1; 45 per cent for those in group 2a and 12.5 per cent for those in group 2b (p less than 0.05), group 2a versus group 2b). The results of this study demonstrate a high mortality and morbidity in patients who fail to increase the serum albumin level after one week of TPN. The data suggest that a prolonged period of parenteral nutrition results in a substantial decrease in perioperative complications in this group of patients.
