Preoperative nutritional risk screening and application of nutritional support in patients undergoing hepatobiliary surgery

Abstract

Objective To provide reference for rational nutritional support by investigating the incidence of preoperative nutritional riskd and the clinical use of nutritional support in patients undergoing hepatobiliary surgery. Methods The patients who had been hospitalized due to hepatobiliary surgery during the period of January 2009 to April 2011 were consecutively enrolled in this study. Nutritional Risk Screening 2002(NRS2002)was conducted on the next morning after admission and the preoperative nutritional support was surveyed. The relationship of nutritional risks with nutritional support was analyzed. Nutritional risk was defined as NRS2002 score ≥ 3. Nutritional therapy included parenteral and enteral nutrition. Results A total of 125 patients were enrolled, and NRS2002 scoring was conducted in all the patients. The total incidence of nutritional risk was 20. 8%. The nutritional risk was significantly higher in the elderly patients(≥65 years old)than in those younger than 64 years(P＜ 0.05). 14 of 26 patients(53.8%)with a score ≥3 received nutrition support while 5 of 26(5.1%)with a score ＜ 3 received nutritional support. The ratio of parenteral nutrition to enteral nutrition was 2. 0 ∶ 1. Conclusions NRS2002 is suitable for the assessment of nutritional risk in patients undergoing hepatobiliary surgery. A proportion of patients were at nutritional risk. The use of nutritional support is currently somehow inappropriate. Evidence-based guidelines are required to improve this situation.
