Comparison of Micronutrient Levels between Oral Feeding and Enteral Feeding in Chronic Stroke Patients

  • 1Department of Rehabilitation Medicine, Veterans Health Service Medical Center, Seoul, Korea. Yang7310@naver.com


This study aimed to investigate the difference in micronutrient levels between oral feeding and enteral feeding in chronic stroke patients to assess the risks of enteral feeding.
Patients with chronic stroke who were admitted to the Department of Rehabilitation Medicine between January 2011 and June 2012 were enrolled. The serum concentrations of iron, copper, zinc, folate, and vitamin B12, as well as the absolute CD4 and CD8 lymphocyte counts, were assessed.
Of the 73 patients enrolled in this study, 50 were fed orally, while the other 23 were fed through a percutaneous endoscopic gastrostomy (PEG) or nasogastric (NG) tube. The serum concentrations of vitamin B12 and folate were significantly higher in the enteral feeding group than in the oral feeding group. However, the serum concentration of zinc was significantly lower in the enteral feeding group.
There is little difference between enteral feeding and oral feeding in terms of micronutrient provision except that the serum concentration of zinc in the enteral feeding group was significantly lower than that in the oral feeding group. Clinicians should recognize that chronic stroke patients who require tube feeding have a risk of micronutrient deficiency. Early detection of malnutrition and micronutrient deficiency is important for providing the necessary nutrients.
