We studied an effect of different nutrition algorithms on the outcome of neurological symptoms and laboratory data in patients with ischemic stroke. The active nutrition support included in the basic therapy from the beginning of the disease has a positive effect on the patient's state. The mixed artificial nutrition (enteral + intravenous) was more effective compared to the intravenous or enteral nutrition alone in improving the clinical state, shortening the duration of staying in intensive care wards and complete compensation of disturbances of protein and energy metabolism during the first day of disease.
