The value of peri-operative nutrition in the sick patient

Abstract

In summary, therefore, the provision of TPN to malnourished patients in the pre-operative period reduces the incidence of post-operative complications, but does not affect post-operative mortality. It is likely that the provision of nutrition by the enteral route is as effective as that by the parenteral route, and may have the extra benefit of resulting in a reduction in infectious complications when compared with patients receiving TPN. Furthermore, the use of enteral nutritional support in the post-operative period may also reduce both septic and major complications, but does not alter mortality. The use of specific combinations of nutrients appears to offer the greatest promise in the use of peri-operative nutritional support. The initial studies reported to date demonstrate reductions in post-operative morbidity, but again there are no benefits on mortality. However, further studies to determine the optimal combinations of nutrients for use in patients in the peri-operative period are urgently required. © Nutrition Society 1997.
