Postoperative nutritional support of patients with abdominal trauma.
The response to major trauma is characterized by a significant erosion of the body cell mass. Intensive nutritional support can decrease morbidity and mortality. Preservation and restoration of the body cell mass involves amino acid synthesis into protein, and this process requires nutrient energy. Newer methods of assessing energy expenditure have revised traditional concepts about energy requirements following trauma. The use of fat to meet some of the caloric requirements may obviate problems with ventilatory distress, glucose intolerance, and hepatic steatosis that occur with glucose-based nutritional regimens. Selection of the delivery method for intensive nutritional support should consider gastrointestinal integrity, physiologic tolerance, and cost. Enteral nutrition is superior to parenteral nutrition in maintaining gastrointestinal mucosal integrity, hormonal balance, and nutrient utilization. Furthermore, it is safer, more convenient, and more economical than parenteral nutrition.
