The OBJECTIVE was to evaluate the informative value of various methods for determining the volume of blood loss during early surgical excision with simultaneous skin grafting with split grafts in patients with full thickness burns.MATERIAL AND METHODS. Our study included 10 patients with burns more than 20 % TBSA. In these patients, from the 2nd to the 5th day after the burn, fascial surgical excision with simultaneous skin grafting with perforated split grafts was performed. To assess the volume of operative blood loss, we used visual, empirical (B. S. Vikhriev; 1986, I. V. Chmyrev; 2011, T. A. Housinger; 1993, T. Janezic; 1997) and calculated (J. B. Gross; 1983, P. G. Budny; 1993, G. D. Warden; 1982) methods. The obtained data were processed by the generally accepted methods of nonparametric statistics.RESULTS. The minimum volume of blood loss was ascertained by visual assessment. We observed the maximum losses in the same patients when using calculated methods. In 5 out of 10 patients, the difference between the minimum and maximum results obtained using different methods exceeded 1000 %.CONCLUSION. Most of the methods used in burn surgery for determining the volume of surgical blood loss are insufficiently representative. To determine the optimal tactics for surgical treatment of patients with severe burns, it is necessary to create formulas for assessing the volume of blood loss, which will take into account laboratory parameters, features of surgical treatment, hydrobalance indicators, anthropometric data and other variables with high predictive value.

Research of the last decade, which revealed the relationship of various socially significant diseases (Alzheimer’s disease, parkinsonism, multiple sclerosis, etc.) with the impact of heavy metals on the human body, stimulates modern science to create drugs that can quickly and safely remove these toxic substances from the body. The article presents a review of studies on the effectiveness of heavy metal adsorption by modern enterosorbents officially registered in the Russian Federation as drugs. The prospects of using non-starch polysaccharides, which are part of modern biologically active additives, in order to create new medicinal substances for the elimination of heavy metals that pose a threat to public health are indicated.

Relevance. The problem of determining intraoperative blood loss in combustiology remains relevant today. With the variety of existing methods of its assessment, the issue of optimizing transfusion therapy remains debatable. Intention. To evaluate effects of the eschar excision area on the complete blood count and to compare results of computational methods for determining volumes of blood loss with actual volumes of blood exfusion. Methodology. 73 burned patients were included in the retrospective study. Early surgical excision with simultaneous autodermoplasty was performed in all patients. To achieve the study purposes, the intervention areas were compared with changes in hemoglobin, hematocrit, volume and number of red blood cells. The prospective study included 20 volunteers who donated 450 ml of the whole blood. In this group, donated volumes were compared with calculated volumes of blood loss (according to PG. Budny and G.D. Warden). The data obtained were processed via Microsoft Office Excel 2007 and IBM SPSS Statistics 20.0 using descriptive, parametric and nonparametric statistics. Results and Discussion. According to the retrospective analysis, actual areas of excision were not consistently related to the changes in complete blood count in the postoperative period. Based on the results of prospective analysis, we were able to reveal correlations between actual volumes of blood loss and changes in hemoglobin concentrations in somatically healthy volunteers (by PG. Budny). There were no similar correlations between volumes of blood loss and decreased hematocrit (by G.D. Warden). Conclusion. According to the results of the study, we couldn't confirm the effectiveness of empirical methods for determining volumes of blood loss in burned patients. The PG. Budny formula gives representative results of blood loss volumes in healthy volunteers. However, the effectiveness of this method in combustiology requires further research.
