Background. Pneumonia is a widespread disease and an often cause of hospitalizations both in Vietnam and Georgia. The supportive treatment of pneumonias includes the respiratory support, the support of fluid and electrolyte balance, parenteral nutrition and some additional drugs (analgesics, corticosteroids, inotropes). Rheo-STAT study is an interventional open-label randomized controlled study of Reosorbilact (“Yuria-Pharm”) effectiveness in pneumonia treatment. The study was held in 7 countries (Ukraine, Moldova, Georgia, Vietnam, Kazakhstan, Kyrgyzstan, Uzbekistan). Objective. To assess Reosorbilact effectiveness in the elimination of the intoxication syndrome. Materials and methods. 628 adult patients with sepsis, peritonitis, pneumonias and burns took part in this study. The pneumonia subgroup included 150 people (62 % males, mean age – 41.3 years, 33 % had some concomitant diseases). Inclusion criteria were the following: age – 18-60 years, community-acquired pneumonia and antibiotic therapy, administered not later than after 48 hours after the disease beginning, at least IV class according to PSI/PORT index, the presence of informed consent, baseline level of SOFA points ≥2. The assessment according to the SOFA scale on the 3rd day of treatment in comparison to the baseline level was the primary endpoint. Secondary endpoints included the change of mean result according to other scales (APACHE II, SAPS II, MODS, PSI/PORT, CURB-65) and changes of biochemical, immunological and integral markers of endogenous intoxication. Results and discussion. Infusion therapy with the help of Reosorbilact (200-400 ml per day) led to the increase of circulating blood volume and to the decrease of total infusion volume without any risk of volume overload. Lactate – one of the Reosorbilact components – did not increase the endogenous lactate level, which testifies a high safety. Inclusion of Reosorbilact into the combined treatment in 3 days led to the body temperature decrease from 39.37 to 36.77 °С, heart rate decrease from 105.27 to 77.81 bpm, leucocytes amount – from 9.38 to 6.64×109/L. Blood oxygenation also increased at the 3rd day of treatment, and PSI/PORT index decreased from 101.47 to 49.07. Pulmonary edema or pleural effusion were not revealed in any patients. Conclusions. 1. Pneumonia is a widespread disease, which often requires hospitalization. 2. Infusion therapy with the help of Reosorbilact increases the circulating blood volume without a risk of volume overload. 3. Inclusion of Reosorbilact into the combined treatment of pneumonia in 3 days leads to the decrease of body temperature, heart rate, leucocyte amount and to the increase of blood oxigenation.

Background. Peritonitis is a consequence of complications of the abdominal cavity organs’ diseases (inflammation, injury) and systemic inflammatory reaction of the organism, which is manifested by symptoms of intoxication and dysfunction of all the organs. In case of diffuse peritonitis mortality is about 80 %. Prerequisites of the lethal outcomes include a late visit to the doctor, elderly age, the presence of cancer and diabetes, antibiotic resistance of the pathogen, diagnostic errors. In the department of purulent gynecology peritonitis most often accompanies endometritis, purulent salpingitis, pyosalpinx, abscesses, uterine perforation during curettage. In Moldova, the principles of treatment of peritonitis include the urgent surgery to remove the infection source, aspiration of exudate, massive lavage, abdominal drainage, antibiotic therapy, and correction of metabolic disorders. Objective. To determine the effectiveness of Reosorbilact in eliminating the intoxication syndrome in peritonitis. Materials and methods. The Rheo-STAT study was an international multicenter, randomized, open-label clinical trial of the efficacy and safety of Reosorbilact (“Yuria-Pharm”) in the treatment of sepsis, peritonitis, community-acquired pneumonia, and burn disease. The study was conducted in 7 countries (Ukraine, Moldova, Georgia, Vietnam, Kazakhstan, Kyrgyzstan, Uzbekistan). 5 of them (Ukraine, Moldova, Georgia, Kazakhstan, Uzbekistan) took part in the sub-study Rheo-STAT Peritonitis. The study involved 628 adult patients with sepsis, peritonitis, pneumonia and burns. The subgroup of peritonitis consisted of 180 people (27 % males, 73 % females; mean age – 37 years; concomitant infectious diseases were observed in 25 %, complicated appendicitis – in 17 %), 117 of them were treated in Moldova (87 % females, 13 % males, mean age – 45.2 years). The inclusion criteria were age 18-60 years, diagnosis of peritonitis, the first hours of the postoperative period, no later than 24 hours from diagnosis to the first visit of the study, obtaining informed consent, baseline level on the SOFA scale ≥2. The total score on the SOFA scale on day 3 of treatment compared to baseline was considered a primary endpoint. Secondary endpoints were the change in the overall score on the APACHE II, SAPS II, MODS, PSI/PORT, CURB-65 scales; changes in biochemical, immunological and integral markers of endogenous intoxication. Results and discussion. Low-volume infusion therapy with Reosorbilact (200-400 ml per day) resulted in an increase in circulating blood volume and a decrease in the total volume of infusions required without the risk of volume overload. Exogenous lactate in Reosorbilact did not increase the content of endogenous lactate, which indicates the high safety of the drug. The inclusion of Reosorbilact in the comprehensive treatment after 3 days provided a decrease in body temperature from 37.1 to 36.75 °C, heart rate – from 88.5 to 82.0 bpm, the leukocyte count – from 11.0 to 7.2×109/L. Reosorbilact therapy in 3 days improved the acid-base balance, as evidenced by the increase in the base excess from -2.73 to -0.57 mmol/L and an increase in standard bicarbonate from 21.8 to 23.5 mmol/L. Conclusions. 1. Prerequisites for the lethal consequences of peritonitis include a late visit to the doctor, elderly age, the presence of cancer and diabetes, antibiotic resistance of the pathogen, and diagnostic errors. 2. Elimination of intoxication syndrome is one of the main components of peritonitis treatment. 3. Reosorbilact infusion therapy increases the volume of circulating blood without the risk of volume overload. 4. The inclusion of Reosorbilact into the comprehensive treatment of sepsis after 3 days provided a decrease in body temperature, heart rate, white blood cell count and normalization of the acid-base composition of the blood.

Background. Infusion therapy (IT) is one of the main methods of drug therapy optimization. The essence of IT is to correct homeostasis disorders in order to detoxify, to restore the disrupted microcirculation and tissue perfusion, to eliminate the disorders of rheological and coagulation blood properties, to eliminate metabolic disorders, to improve drug delivery to the pathological focus, to restore circulating blood volume, to normalize fluid and electrolyte and acid-base balance. Objective. To describe modern IT. Materials and methods. Analysis of the literature sources on this topic. Results and discussion. Requirements for modern plasma substitutes include safety, sufficient and long-lasting volemic effect, rapid renal excretion, lack of accumulation and effect on the coagulation system, maximum similarity to blood plasma, and availability. There are several classes of plasma substitutes, and each of them has its own indications. For example, crystalloids are prescribed for dehydration, and colloids – for hypovolemia. The infusion volume is calculated based on the physiological needs of the organism, taking into account pathological fluid loss (fever, shortness of breath, postoperative wound drainage, vomiting, polyuria). Endogenous intoxication (EI) – a pathological condition that occurs as a result of exposure to toxic substances of exogenous or endogenous nature, which cause dysfunction and the development of extreme conditions – is an important field of IT application. EI can accompany chronic heart failure, peripheral vessels atherosclerosis, autoimmune and allergic diseases. Toxins have a direct (direct destruction of proteins and lipids, blocking of synthetic and oxidative processes in the cell) and indirect (microcirculation system and vascular tone disorders, changes of blood rheological properties) adverse effects. Clinical manifestations of EI include fever, malaise, and the dysfunction of various internal organs. As EI depletes the natural mechanisms of detoxification, worsens the clinical course of the disease, reduces drug sensitivity, suppresses immunity, it is an indication to detoxification via infusion. The tasks of the latter are to improve tissue perfusion, to provide hemodilution with a decrease in the toxins’ concentration, to stimulate diuresis, to eliminate acidosis, and to maintain the functional state of hepatocytes. For this purpose, solutions of polyatomic alcohols (Reosorbilact, Xylate, “Yuria-Pharm”) can be used. Reosorbilact increases the circulating blood volume, improves microcirculation and rheological blood properties, increases tissue perfusion, promotes “wash-out” of toxins, corrects acidosis and fluid and electrolyte balance, normalizes hepatocyte function, improving the own detoxification mechanisms. In case of microcirculation disturbances, it is reasonable to use the combined IT with the inclusion of Reosorbilact, Latren and Tivortin (“Yuria-Pharm”). Latren increases the elasticity of erythrocytes, reduces the aggregation of erythrocytes and platelets, normalizes the electrolyte composition of blood plasma, and Tivortin acts as a substrate for the formation of nitric oxide – the main signaling molecule of the endothelium. In addition to EI, IT usage is often prescribed for diabetic ketoacidosis. In such cases, it is advisable to use Xylate (“Yuria-Pharm”), which has antiketogenic properties, improves hemodynamics, corrects acidosis, and does not increase blood glucose levels. Xylate is recommended to be used only after preliminary rehydration with the help of isotonic saline solutions. Conclusions. 1. IT is an important method of treating a number of diseases. 2. EI accompanies not only diseases that involve intoxication syndrome, but also almost all internal diseases. 3. Reosorbilact and Xylate are the optimal solutions for detoxification. 4. It is reasonable to use combined IT, for example, the combination of Reosorbilact with Latren and Tivortin.

Intraosseous Infusion

Traumatic shock is considered to be the most common clinical form of a severe patient’s condition (63%). Timely and adequate blood volume resuscitation is one of the most important procedures in providing medical care to critically injured casualties and patients at the forward medical evacuation stage. The key to this problem, especially when the infusion therapy is needed at the pre-hospital stage, is the development of alternative (extravascular) techniques of plasma volume expander administration. The article presents the results of testing of the first domestic medical devices for intraosseous infusion in critically injured casualties and patients. At present, on commission of the Russian Ministry of Defense and with the scientific support of Kirov Military Medical Academy, domestic enterprises developed test samples of medical devices to provide intraosseous infusions: a «Disposable device for intraosseous infusion of solutions if there is no intravenous access, which was designed on the basis of a spring drive» - the index «VKI-P», developed by limited liability company «Novoplast-М» and a set for intraosseous infusion using an electric drive - the index « VKI-E», developed by limited liability company «Research engineering company «Spetsproekt». Assessment of performance of test samples of the medical devices for intraosseous infusions «VKI-P» and «VKI-E» was carried out using pathophysiologic model of traumatic shock in 14 experimental animals (pigs) by creating artificial blood loss of medium severity, 25% of circulating blood volume (in average 440 ml), followed by its resuscitation with intraosseous infusion of 0,9% solution of NaCl. As a result of the performed tests it was found that the device «VKI-P» and the set «VKI-E» provide for NaCl infusion in major vessels (with an intraosseous infusion), 750 ml of volume during 45-50 min, and can be used as an alternative access to provide infusion as a part of anti-shock therapy, which solves the problem of volume resuscitation when giving care to severely injured casualties and patients at the forward medical evacuation stages. These samples may be recommended for inclusion into the medical service list of complete supplies and the Medical Corps supply support, the Armed Forces of the Russian Federation.

In the article, there are considered questions of physiological changes of the blood volume status during pregnancy, parturition and in the postpartum period, features of functional and structural changes of the cardiovascular system. The determination of the circulating blood volume is still a stumbling block for obstetrician-gynecologists and anesthesiologists-resuscitators. Our view of the normal blood volume status during pregnancy is important in light of the assessment of the blood loss in the development of massive obstetric hemorrhage. The doctor needs to know what changes in the cardiovascular system are physiological and which are pathological in case of blood loss, with taking into account the functional changes in the heart that occur during pregnancy, parturition and in the earliest postpartum period. A deeper understanding of this problem will help the doctor avoid aggressive infusion therapy, which can lead to complications.

The rectal temperature of dogs was reduced to 27°C and stabilized at this level for a period of at least 3 hours. The heart rate, blood pressure, respiration rate, blood volumes, extracellular volume (thiocyanate space), and total body water (antipyrine space) were recorded during the reduction in temperature and the period of stable body temperature. No change was observed in the mean arterial pressure during any period of hypothermia; the heart rate decreased exponentially during the reduction in body temperature but remained constant during the stable period. Blood volume increased during the initial stages of hypothermia (33°C to 36°C) and remained at this level. Hematocrit and erythrocyte volume followed the same pattern as total blood volume, with no alteration in the plasma volume. There were no shifts in the extracellular or intracellular volumes at any time during the hypothermic state.

1. The aim of this study was to determine the effects of caffeine on haemodynamic and neurohumoral responses to meal ingestion in elderly patients with a history of symptomatic postprandial hypotension. 2. Postprandial hypotension is a common disorder of blood pressure regulation in the elderly, associated with falls and syncope. The pathophysiological mechanism is thought to be related to impaired vascular compensation for splanchnic blood pooling after a meal. Since caffeine inhibits vasodilatory adenosine receptors in the splanchnic circulation, we postulated that caffeine would reduce splanchnic blood pooling and prevent the development of postprandial hypotension. 3. We conducted a randomized, double-blind, placebo-controlled, cross-over study in nine elderly patients [age 76 ± 9 (SD) years] with histories of symptomatic postprandial hypotension. Standardized 1674 kJ liquid meals with 250 mg of caffeine or placebo were given on two occasions, at least 1 week apart. Blood pressure, heart rate, forearm vascular resistance (by venous occlusion plethysmography), and plasma caffeine and catecholamine levels were measured. Cardiac and splanchnic blood volume were determined by radionuclide scans. 4. By 30 min after both caffeine and placebo meal studies, supine mean arterial blood pressure fell significantly (P = 0.006) by 31 ± 7 and 19 ± 6 mmHg, respectively (mean ± SEM, between group difference was not significant). Heart rate, cardiac output and splanchnic blood volume increased significantly, but to a similar extent, after caffeine and placebo. Forearm vascular resistance was unchanged after both meals. 5. Oral caffeine given with a meal does not reduce splanchnic blood pooling nor prevent postprandial hypotension in symptomatic elderly patients.

Abstract Background Post-spinal anesthesia (PSA) hypotension in elderly patients is challenging. Correction of PSA hypotension by fluids either colloids or crystalloids or by vasoconstrictors pose the risk of volume overload or compromising cardiac conditions. Dexamethasone is used to treat conditions manifested by decrease of peripheral vascular resistance. The research team was the first to test the hypothesis of its role in preventing or decreasing the incidence of PSA hypotension. Methods One hundred ten patients, aged 60 years or more were recruited to receive a single preoperative dose of dexamethasone 8 mg IVI in 100 ml normal saline (D group) (55 patients) 2 h preoperatively, and 55 patients were given placebo (C group) in a randomized, double-blind trial. Variations in blood pressure and heart rate in addition to the needs of ephedrine and/or atropine following spinal anesthesia (SA) were recorded. SA was achieved using subarachnoid injection of 3 ml hyperbaric bupivacaine 0.5%. Results Demographic data and the quality of sensory and motor block were comparable between groups. At 5th, 10th minutes post SA; systolic, diastolic and mean arterial pressures were statistically significant higher in D group. At 20th minutes post SA; the obtained blood pressure readings and heart rate changes didn’t show any statistically significance between groups. The need for ephedrine and side effects were statistically significant lower in D group than C group. Conclusion Post-spinal anesthesia hypotension, nausea, vomiting and shivering in elderly patients were less common after receiving a single preoperative dose of dexamethasone 8 mg IVI than control.

Abstract Introduction Stress reactivity and autonomic nervous system (ANS) dysregulation have been suggested to be the pathophysiology of insomnia. Based on the finding PSG-measured short sleep duration was associated with higher morbidity of metabolic and cardiovascular disease. Vgontzas and Fernandez-Mandoza (2013) proposed that objective sleep duration is a biomarker for insomnia phenotypes. The phenotype with short objective sleep duration is associated with increased stress-related physiological hyperarousal. The present study aims to test this hypothesis by comparing the stress-induced cardiovascular reactivity between insomnia patients with short and long objective sleep durations. Methods 27 insomnia patients (age mean 34.48 ±12.87, Male: Female= 6:21) without comorbidity of psychiatric, medical or sleep disorders participated in this study. They went through one night of 8-hour PSG recording and were divided into two groups by their total sleep time with a cutoff of 6 hours. Nine participants were in short sleep duration group and 18 in longer sleep duration group. Psychophysiological reactivity profile, as recorded with EKG, skin conductance (SC), body temperature (BT), blood volume pulse (BVP), respiration rate (RR), was measured under three conditions: baseline resting state, arithmetic word problems solving, and recovery resting state. Results Both groups showed similar stress physiological response with increased heart rate (HR) and SC, nearly equivalent BT and BVP, and decreased RR when solving arithmetic problems, and opposite reaction during recovery resting state. Mann-Whitney U test comparing the changes from baseline resting state on all the psychophysiological measures between two phenotypes of insomnia showed no significant differences: stress-induced heart-rate (U=106, p=.119.) recovery heart-rate (U=44, p=.095), stress-induced skin conductance (U=104.5, p=.132),recovery skin conductance (U=51.5, p=.198), stress-induced body temperature (U=79, p=.897),recovery body temperature (U=60.5, p=.418), stress-induced blood volume pulse amplitude (U=77, p=1.0), and recovery blood volume pulse amplitude (U=69, p=.735), stress-induced respiration rate (U=76, p =.696), and recovery respiration rate (U=85, p=.658). Conclusion Our results indicate that the insomnia phenotypes with short and long objective sleep duration are not different in their stress-induced physiological responses. Future studies are needed to confirm these results and to explore other mechanisms for the increased metabolic and cardiovascular disease risk in insomnia patients with short objective sleep duration.
