[Serum creatine phosphokinase as a predictor of upper limb amputation in electrical trauma]. / Soderzhanie kreatinfosfokinazy v plazme krovi kak prediktor amputatsii verkhnei konechnosti pri elektrotravme.

OBJECTIVE: To study the relationship between serum creatine phosphokinase and outcomes of injury in victims with electrical burns. MATERIAL AND METHODS: Among 40 patients with electrical injury, 7 (18%) ones underwent upper limb amputation. There were 37 (92.5%) men and 3 (7.5%) women aged 37 (28; 47) years. We analyzed total serum creatine phosphokinase and MB fraction on the first day in patients with and without amputations. RESULTS: Total serum creatine phosphokinase exceeded the upper reference value in 11 out of 33 patients without amputation and in all 7 patients with limb amputation (p=0.001). Patients with limb amputation had significantly higher total serum creatine phosphokinase and MB fraction (p<0.001 and p=0.030, respectively). Logistic regression equation showed that high total serum creatine phosphokinase significantly influenced amputation rate (p<0.001), as evidenced by odds ratio (42.7, 95% CI 3.5-514.8). ROC analysis revealed the cut-off value of total serum creatine phosphokinase (950 IU/L). Sensitivity was 100% (63; 100), specificity - 94% (86; 94), positive predictive value - 78% (49; 78), negative predictive value - 100% (92; 100). CONCLUSION: Total serum creatine phosphokinase depends only on severity of electrical and flame burns. Serum creatine phosphokinase is a predictor of upper limb amputation in patients with electrical injury. Total serum creatine phosphokinase ≥ 950 IU/L is significant for upper limb amputation (in CK-MB fraction within the reference values).

[Correlation between biochemical parameters of oxidative stress, endogenous intoxication and regulation of vascular tone in patients with burn injury].

Burn injury is accompanied by the formation of reactive oxygen species (ROS). Excessive production of ROS results in oxidative stress. Peroxidation damage of proteins causes their degradation and the formation of toxic fragments con- tributing to the development of endogenous intoxication. Furthermore, burns cause pronounced inflammatory reaction in the lesion site leading to poor circulation. The purpose of this study was an investigation of relationship between disturbances in the prooxidant/antioxidant system, severity of endogenous intoxication and disturbances of endogenous vascular regulation to assess the severity and prognosis of complications in patients with burn injury. 26 patients with- burn injury were investigated; they were divided into 2 groups according to the severity of injury on the basis of Frank index (FI): group 1--FI < 60 CU and group 2--FI ≥ 60 CU. The investigation of blood serum was performed on 1-3, 7, 14, 21 and 28 day after burn injury. Malondialdehyde (MDA), total antioxidant status (TAS), the level of middle weight molecules, stable metabolites of nitric oxide (NOx) and angiotensin-converting enzyme (ACE) activity were determined in the serum. Significant increase of MDA level, decrease of TAS and NOx level were found in two groups of patients throughout the observation period. We also found a disturbance in coupled interaction of NO and ACE. These data point to the development of oxidative stress and imbalance in endogenous regulation of vascular tone. There was a trend toward more pronounced oxidative stress in group 2. Significant correlations between parameters of oxidative stress, endogenous intoxication, endogenous factors of vascular regulation, depth of burn injury and FI were obtained in two groups. MDA, TAS can serve as one of the prognostic markers of condition severity of burned patients and therapy adequacy.

[Gastroduodenal bleedings in critical illness]. / Gastroduodenal'nye krovotecheniia pri kriticheskikh sostoianiiakh.

Acute erosive lesions of upper parts of gastrointestinal tract with bleeding aggravate severe burn trauma, postoperative period after extensive surgeries and is the often component of polyorganic insufficiency syndrome. Gastric secretion in patients with severe burn trauma and neurotrauma was studied. Decrease of gastric secretory function due to central paresis of gastrointestinal tract and reflux of bile into stomach was seen in majority of patients with neurotrauma and acute gastric ulcers. On the contrary, in patients with burn shock increase of acid-secretory function of stomach was revealed. Schemes of prophylaxis and treatment of acute ulcers were developed. They included antacid therapy (for patients with increased secretion), regulators of motor-evacuatory function of stomach and intestine (for patients with paresis), drugs increased regenerative properties of mucosa, early enteral nutrition with balanced mixtures. This treatment in combination with hemostatic therapy and cure of main disease permitted to reduce number of gastroduodenal bleedings and lethality in these patients.

[Criteria for assessment of endogenous intoxication in burn trauma]. / Kriterii otsenki éndogennoi intoksikatsii pri ozhogovoi travme.

Registered in patients with burn trauma was the presence of endogenous intoxication (EI), which was determined by a higher value of coefficient CLP/AOS, a higher contents of medium-molecular peptides (MMP), a lower total and effective concentration of albumin (TAC and EAC) and by a reserve of the binding albumin ability. Intoxication coefficients, i.e. IC MMP/EAC and IC C/EAC showing the deposition and binding of toxic ligands, were acknowledged as the most informative EI parameters.

Clinical and laboratory evaluation of pectins application efficacy demonstrated that the patients treated with pectines has lower frequency of bacteriemia, intoxication, infectious complications and lethality. Pectins use per os resulted by acceleration of burns wounds healing and by lower microbial dissemination. Frequency of coagulase-positive staphylococci, streptococci and enterococci isolation was also lower in the treated group of patients when compared to the control group. Feces microbial profile also demonstrated positive trend--normal microflora (bifidobacteria and lactobacilli) enhanced, opportunistic bacteria diminished. Pectins application provided normalization of leucocytes, lymphocytes, B-lymphocytes, immunoglobulins A and G. The results of investigation demonstrated pectins efficacy at the complex treatment regimes of the patients with burns.

The results of the burned wounds treatment with 1-2% solution of apple or beet pectins were analysed. The control results were examined at the same patients with symmetrical wounds treated by chlorhexidine, levomecol, furacillin liniment. Clinical evaluation demonstrated good tolerability of the treatment regime, absence of side effects and complications, inhibition of inflammation, acceleration of epithelisation of the burns II-IIIA class, allowed to diminish the preliminary period before autodermoplastic operation (burns of IIIB class), diminished microbial dissemination and dissemination with Pseudomonas aeruginosa. The best results were demonstrated when the pectins application was performed since the first day after the burned injury.

Acute erosive ulcerative hemorrhage (EUH) is one of the most grave complications of burn disease, caused by impaired blood rheology, clotting, and protein status. Twenty-three patients with burns of 12-70% body surface were examined, 17-25% of burns being deep. The most pronounced changes in blood rheology and clotting with formation of erythrocyte aggregations, fibrin precipitation and imbalance of visceral proteins were observed during the shock stage (days 1-3), particularly pronounced in patients with acute EUH. Development of septicotoxemia favored secondary increase in blood clotting and rheological parameters, which led to thrombotic complications. The data helped improve the complex of infusion-transfusion therapy for preventing and treating ulcerative and erosive lesions.

Results of clinical and laboratory evaluation of the treatment with pyobacteriophage in tablets of the patients with burn wounds are presented. It was shown that phagotherapy provided more rapid cure of pyoseptic complications, temperature normalization, wounds purification and lower lethality Bacteriological analysis of wound secretions revealed that after the treatment staphylococci and streptococci were cultured 2 times rarely, Proteus spp. Were isolated 1.5 times rarely, E. coli was not isolated. The amount of positive haemocultures also diminished. Investigation of immunologic status demonstrated statistically significant normalization of immunity on cell level. Phagocytosis level didn't change while in control group (without bacteriophage use) it became lower. Antibody level enhanced but less extensively than in control group. The results of trial demonstrates positive effect of phagotherapy use at the patients with burns.
