A Prospective Study Of Nutritional Support To Improve The Nutritional Status Of Critically Ill Patients With Kidney Disease

Objctive:To investigate the prevalence of nutritional risk and malnutrition in critically ill patients with kidney disease; To prospectively observe the clinical efficacy of short-term nutritional support.Methodology:Adult patients in renal ICU were enrolled from August,2011to June,2012. Nutritional Risk Screening2002(NRS2002) was performed in all patients. We decided nutritional support upon Patients with a total score of≥3.Results:466patients underwent NRS2002, Overall prevalence of nutritional risk was25.1%and malnutrition was87.3%.137patients [76males,61females, mean age(40.0±17.3)years] received nutritional support. Among them, food fortification in23cases(16.8%),enteral nutrition(EN) in97cases(70.8%),parenteral nutrition(PN) in2cases (1.5%),EN plus PN in15cases(10.9%).The energy intake were (15.4±7.3)Kcal/kg in first day,(20.9±8.2)Kcal/Kg in third day,(22.3±8.5)Kcal/Kg in seventh day (P=0.001). The protein intake were0.5±0.2g,0.6±0.3g,0.7±0.3g respectively (P=0.001).After a week of nutritional support, the serum concentrations of Alb, PA, TF and LC increased obviously (p=0.001); the I/E of male and female were increased respectively(P=0.044and0.248).Conclusion:The prevalence of nutritional risk and malnutrition was87.3%,25.1%respectively in critically ill patients with kidney disease. After short-term nutritional support, the serum concentrations of Alb, PA, TF and LC as well as Abnormal distribution of body water were improved.
