[Parenteral use of a fat emulsion in the early postoperative period].
Parenteral application of fat emulsions has been established as useful in long term artificial nutrition especially during weaning off the ventilator. In order to ascertain whether these advantages can also be proved in nonventilated patients in the immediate postoperative phase, alternatively carbohydrates versus a new fat emulsion were investigated. 30 patients were randomly allocated to three different nutrition regimens. The caloric and nitrogen supplementation was identical for all groups, while the carbohydrate and fat content was different. Group I: only carbohydrates (as caloric source), group II: high fat load (3 g/kg/day), group III: medium fat dosage (1.5 g/kg/day). Routine laboratory parameters as well as acid-base-status and fat metabolism were evaluated. While most of the routine parameters were not significantly different between the groups, triglyceride levels in serum were highest in group II but never exceeding 280 mg/dl (-x). Nitrogen balance as well as protein metabolism were significantly improved using regimen III, thus documenting the beneficial effect of a medium fat dosage in the immediate postoperative phase. Parenteral nutrition combining amino acids, carbohydrates and a fat emulsion seems to be the optimal postoperative regimen even in patients without ventilatory support.
