Introduction. Damage to the central nervous system and multi- organ trauma are conditions that qualify patients for treatment in the intensive care unit. The diagnosis of nutritional disorders and the early implementation of nutritional therapy is extremely important, accelerates the process of regeneration of the body, and thereby hospitalization of the patient. Aim. Evaluation and comparison of nutritional status of patients with damage to the central nervous system and multi-organ trauma treated in the intensive care unit Material and methods. The study involved 102 people: with the central nervous system damage (48 people) and multi-organ trauma (54 people). The methods of descriptive statistics were used and a qualitative analysis was carried out. Results. In the study group, the nutritional status assessed in the 5th week of stay for albumin values deteriorated compared to the 1st week of admission to the ward. Patients with damage to the central nervous system had the protein value in the blood serum below the accepted norm. Each week, the values approached the normal range, while patients with multiple -organ trauma statistically maintained the level of protein below the accepted norm throughout the entire period of hospitalization. In the group of patients with the central nervous system damage, the nutritional status assessed in the 5th week of stay for the total number of lymphocytes improved compared to the fi rst week of stay, and in the group of patients after multi-organ trauma, the nutritional status evaluated in the 5th week of stay for the total number of lymphocytes deteriorated compared to the fi rst week of the stay. Conclusions. Evaluation of the nutritional status of all patients in the intensive care unit indicated the occurrence of malnutrition in 76% of these patients and the worsening during 5 weeks of hospitalization.
