BACKGROUND: Fluid therapy in the intensive care unit is one of the most common components of therapy, but at the same time one of the most controversial and widely discussed. The choice of volume and type of infusion is a multifactorial issue. Currently, the search continues for a convenient non-invasive method, which can be used to assess the water composition of the patient's body.
AIMS: analysis of the distribution of fluid sectors in patients in chronic critical illness using the bioimpedance with standard fluid therapy.
MATERIALS AND METHODS: The study included 63 patients in CCI after brain damage, 28 men, 35 women, the average age 54 19 years. According to nosology: ischemic stroke 22, traumatic brain injury 17, hemorrhagic stroke 14, condition after brain surgery 7, post-hypoxic conditions 2. The study was carried out in the morning before breakfast using the analyzer of bioimpedance metabolic processes and body composition ABC-02 "Medass". A total of 140 measurements were conducted.
RESULTS: It drew attention to the fact that in most cases the volume of the total body water (TBW) in patients was within the age and sex norm (78.6%), however, the volume of extracellular water (ECW) reached normal values only in 45.7%. Moreover, both indicators were simultaneously within the normal range only in 44.3%. Then we found that TBW and ECW did not coincide at 35.7%. The most common option for this was an increase in ECW while maintaining a normal TBW (24.3%). When conducting a correlation analysis of TBW and ECW indicators with biochemical blood test data (a decrease in the total protein level, a decrease in the albumin level), the strength of the relationship between the correlation coefficients of the samples on the Chaddock scale turned out to be very weak for all the options considered.
CONCLUSIONS: In patients in CCI after brain damage, in more than 50%, there may be an accumulation of water in the extracellular space without visible edema, while in 24.3% the total body water indicator is within the age and sex norm. This indicator doesnt depend on either the level of hypoproteinemia or hypoalbuminemia.
