Immunonutrition Versus Standard Enteral Nutrition Before Major Surgery
|ClinicalTrials.gov Identifier: NCT00512213|
Recruitment Status : Completed
First Posted : August 7, 2007
Last Update Posted : April 24, 2012
The aim of this trial is to compare preoperative Imunnonutrition with standard enteral nutrition regarding morbidity after major abdominal surgery in patients with NRS greater 3.
The primary end point is the complication rate until 30 days after surgery.
|Condition or disease||Intervention/treatment|
|Major Abdominal Surgery||Dietary Supplement: Immunonutrition for 5 days preoperative Dietary Supplement: Standard enteral nutrition for 5 days preoperative|
Malnutrition affects about 20-50% of all patients in hospital [1, 2]. Major surgery further increases postoperative malnutrition and immunity reduction. Therefore, postoperative complication and infection rates after major surgery exceed 30% [3-6].
The nutritional risk score (NRS)  is based on the ESPEN (European society of parenteral and enteral nutrition) screening guidelines and identifies patients who are likely to benefit from nutritional support. Patients with a NRS ≥ 3 are considered severely undernourished, or to have a certain degree of severity of disease in combination with certain degree of malnutrition .
In a prospective cohort study patients with a NRS ³ 3 had significant more infectious and overall complications after major abdominal surgery [4, 7, 8]. Several studies showed a benefit by nutritional support on complications [3, 5, 6]. International guidelines suggest therefore preoperative oral nutritional support for malnourished patients undergoing major surgery . However, it remains controversial whether standard enteral nutrition (SEN) or immunonutrition (IN) is preferable .
IN, containing arginine, ribonucleic acid and omega-3 polyunsaturated fatty acids aims to improve the nutritional status, immunological function and clinical outcome [5, 10].
