    Aim of the study. To investigate the preconditioning effect of sevoflurane on small intestinal mucosa in experimental hemorrhagic hypotension.Material and methods. The study was performed on a cohort of 106 male rats that included two experimental groups: one exposed to ether (Group 1, n=40) and another one exposed to sevoflurane (Group 2, n=40); two control groups included 20 intact animals, of which 10 were anesthetized with ether and 10 with sevoflurane. Six animals were excluded from the study because they died by the 2nd hour of hemorrhagic hypotension under ether anesthesia. The study parameters were measured at 15 min, 30 min, 1 h, and 2 h of hemorrhagic hypotension. Amylolytic activity of the small intestine mucosa was determined by E. A. Zabelinsky, B. W. Smith and I. M. Roe technique modified by A. M. Ugolev. The data were statistically analyzed using the nonparametric Mann-Whitney method.Results. By 15 min of hemorrhagic hypotension, the activity of amylase fractions in all small intestine regions in Group 2 animals was significantly lower vs the Group 1 rats. By 30 min of hemorrhagic hypotension, the activity of the enzyme fractions in all small intestine regions in Group 2 animals remained significantly lower than in Group 1, by an average of 2 to 9 times (P=0.01; P<0.001), and after 1 h of hemorrhagic hypotension, it was 2 and 4 times lower (P=0.02; P<0.001). By the 2nd hour of hemorrhagic hypotension, the activity of nearly all duodenal amylase fractions in the Group 2 animals remained 3-4 times lower compared to Group 1. Meanwhile, a significantly higher activity of slowly desorbing and intracellular amylase fractions vs the control group was observed in jejunum and ileum.Conclusion. In hemorrhagic hypotension under sevoflurane anesthesia, a decrease of the pancreas excretory function, stabilization of the brush border of the mucosa of all small intestine regions, including enterocyte membranes, was found during the first hour of experiment. Two hours after the hemorrhage, the biochemical evidence of brush border damage in the jejunum and ileum was revealed

    Objective: to study the efficiency of pre-administration of trimetazidine in experimental cardiac contusion in order to lower the degree of posttraumatic myocardial dysfunction. Materials and methods: experiments were carried out on non-inbred albino male rats anesthetized with sodium thiopental. Cardiac contusion was reproduced by an original device that imitated a blow of the steering wheel to the anterior chest, as that observed when a moving car clashes against an obstacle. Some animals were traumatized after preadministration of trimetazidine (25 mg/kg intraperi-toneally). An electrocardiogram, left carotid blood pressure, an integral rheogram, and the first derivative of a differential rheogram were recorded in the direct fashion prior to cardiac contusion simulation and in different posttraumatic periods. Stroke volume, cardiac output, and total peripheral vascular resistance were calculated. Results. Preinjection of trimetazidine significantly prevented the development of arrhythmias in the early posttraumatic period and improved systemic hemodynamic parameters: stroke volume, cardiac output, blood pressure, and total peripheral vascular resistance. No death case within the first hour of a posttraumatic period was an integral criterion for the efficiency of preventive use of trimetazidine in cardiac contusion. Conclusion: trimetazidine produces a cardioprotective effect in experimental cardiac contusion, which shows it possible to clinically use the agent and provides indirect evidence that the ischemically hypoxic mechanism is involved in cardiac traumatic lesion. Key words: experimental cardiac contusion, central hemodynamics, arrhythmias, trimetazidine.ЦСль исслСдования .

    Objective: to study the efficiency of pre-administration of hypoxen in experimental cardiac contusion in order to lower the degree of posttraumatic myocardial dysfunction. Materials and methods: experiments were carried out on non-inbred albino male rats anesthetized with sodium thiopental. Cardiac contusion was reproduced by an original device that imitated a blow of the steering wheel to the anterior chest, as that observed when a moving car clashes against an obstacle. Some animals were traumatized after pre-administration of hypoxen. An electrocardiogram, left carotid blood pressure (BP), an integral rheogram, and the first derivative of a differential rheogram were recorded prior to cardiac contusion simulation and in different posttraumatic periods. Stroke volume (SV), cardiac output (CO), and total peripheral vascular resistance were calculated. Results. Preinjection of hypoxen completely prevented the development of sinus arrhythmia, paroxysmal ventricular tachycardia, and intraatrial and intraventricular conduction disturbances, irrespective of the baseline BP. In a subgroup of animals with a baseline low BP, the agent reduced the incidence of bradycardia by 1.5 times, heterotopic rhythms by 5.3 times, ventricular premature contractions by 6 times, atrioventricular (AV) block by 5.3 times and diminished the changes in the terminal of a ventricular complex by 6.3 times. In a subgroup of animals with baseline normal BP, bradycardia and heterotopic rhythms were recorded 2 and 7 times more infrequently recorded; ventricular premature beats, AV block, and ST-segment displacement were present in none case. Preinjection of hypoxen improved myocardial contractility, as evidenced by 17β€”25% SV increases within an hour posttraumatically. However, significant arterial hypotension and lowered CO due to bradycardia in most experimental animals during the preinjection of hypoxen before injury and throughout the posttraumatic period caused a ten-fold increase in mortality rates as compared with the non-hypoxen group. Conclusion. The hemodynamic effects of hypoxen can substantially limit the possibility of using the agent to diminish the degree of posttraumatic cardiac dysfunction. Key words: experimental cardiac contusion, central hemodynamics, hypoxen.ЦСль исслСдования β€” ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ ΡΡ„Ρ„Π΅ΠΊΡ‚ΠΈΠ²Π½ΠΎΡΡ‚ΡŒ ΠΏΡ€Π΅Π΄Π²Π°Ρ€ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ ввСдСния гипоксСна ΠΏΡ€ΠΈ ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½ΠΎΠΌ ΡƒΡˆΠΈΠ±Π΅ сСрдца с Ρ†Π΅Π»ΡŒΡŽ ΡƒΠΌΠ΅Π½ΡŒΡˆΠ΅Π½ΠΈΡ выраТСнности посттравматичСской ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ дисфункции.

    Objective: to study the incidence and pattern of cardiac arrhythmias and other abnormalities in the early posttraumatic period of experimental cardiac contusion and to assess their contribution to death and the development of posttraumat-ic myocardial dysfunction.Materials and methods: experiments were carried out on non-inbred albino male rats anesthetized with sodium thiopental. An electrocardiogram, respiration rate, and left carotid blood pressure were recorded in the direct fashion. Cardiac contusion was reproduced by an original device that imitated a blow of the steering wheel to the anterior chest, as that observed when a moving car clashed against an obstacle. Some animals were traumatized after preadministration of atropine sulfate.Results: sinus bradycardia accompanied by bradypnoea or short-term apnoea and lowered blood pressure is a compulsory and persistent ECG abnormality. Preinjection of atropine significantly prevents the occurrence of these changes and points to the likely reflectory mechanism of their development. Other ECG abnormalities (heterotopic rhythms, premature beats, conduction blockade, terminal ventricular complex changes, etc.) are encountered in a variety of combinations, including those among which typical changes that are undetectable, are diverse, short-term, and labile. Among them, there are virtually no hemodynamic and potentially fatal arrhythmias.Conclusion: in experimental isolated cardiac contusion, the pattern of cardiac arrhythmias differs from that observed in the inpatient setting. Cardiac arrhythmias and other ECG abnormalities do not make a considerable contribution to a mortality rate under the conditions of this experiment since there are no hemodynamic ones. ЦСль исслСдования : ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ частоту развития ΠΈ структуру Π½Π°Ρ€ΡƒΡˆΠ΅Π½ΠΈΠΉ сСрдСчного Ρ€ΠΈΡ‚ΠΌΠ° ΠΈ Π΄Ρ€ΡƒΠ³ΠΈΡ… Π­ΠšΠ“-ΠΎΡ‚ΠΊΠ»ΠΎΠ½Π΅Π½ΠΈΠΉ Π² Ρ€Π°Π½Π½Π΅ΠΌ посттравматичСском ΠΏΠ΅Ρ€ΠΈΠΎΠ΄Π΅ ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ ΡƒΡˆΠΈΠ±Π° сСрдца, Π° Ρ‚Π°ΠΊΠΆΠ΅ ΠΈΡ… Π²ΠΊΠ»Π°Π΄ Π² Π»Π΅Ρ‚Π°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ ΠΈ Ρ„ΠΎΡ€ΠΌΠΈΡ€ΠΎΠ²Π°Π½ΠΈΠ΅ посттравматичСской ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ дисфункции.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹: экспСримСнты Π²Ρ‹ΠΏΠΎΠ»Π½Π΅Π½Ρ‹ Π½Π° Π±Π΅Π»Ρ‹Ρ… бСспородных крысах-самцах, Π½Π°Ρ€ΠΊΠΎΡ‚ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹Ρ… Ρ‚ΠΈΠΎΠΏΠ΅Π½Ρ‚Π°Π»ΠΎΠΌ натрия.

    Aim. To provide a rationale for the feasibility of using the succinate-containing drugs to treat hypoxia associated with COVID-19 based on the analysis of experimental and clinical studies.Materials and methods. 84 Russian and international literature sources concerning the pathogenesis of COVID-19 and the pathogenetic role of succinate in the management of COVID-19 associated hypoxia, oxidative stress and diaphragmatic dysfunction were analyzed. The literature search was performed using Pubmed and ELIBRARY.ru databases.Results. The literature analysis showed that tissue hypoxia, triggering the pathomorphological cascade of events and resulting in multiple organ failure is a central element of COVID-19 pathogenesis. Experimental and clinical studies show the positive impact of tissue hypoxia correction using succinate in both adult patients and children with various conditions associated with acute respiratory failure.Conclusion. The literature data provide a rationale for using succinate-containing drugs in the treatment of severe COVID-19

    The paper estimates the hypoxic sensitivity of isolated isovolumetrically contracting hearts of non-inbred albino male rats experiencing 4-min clinical death from acute blood loss. In the early postresuscitative period, the inhibited contractility of the myocardium and its increased hypoxic sensitivity has been ascertained to be due to impaired bioenergetics and activated lipid peroxidation processes. A four-fold pO2 reduction in the Krebs-Henseleit solution causes a more rapid and more marked development of myocardial contractures and oxygenized solution-induced reperfusion brings about greater myocardial damages.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ оцСниваСтся Ρ‡ΡƒΠ²ΡΡ‚Π²ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ ΠΊ гипоксии ΠΈΠ·ΠΎΠ»ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹Ρ… ΠΈΠ·ΠΎΠ²ΠΎΠ»ΡŽΠΌΠΈΡ‡Π΅ΡΠΊΠΈ ΡΠΎΠΊΡ€Π°Ρ‰Π°ΡŽΡ‰ΠΈΡ…ΡΡ сСрдСц Π±Π΅Π»Ρ‹Ρ… бСспородных крыс-самцов, ΠΏΠ΅Ρ€Π΅Π½Π΅ΡΡˆΠΈΡ… 4-ΠΌΠΈΠ½ΡƒΡ‚Π½ΡƒΡŽ ΠΊΠ»ΠΈΠ½ΠΈΡ‡Π΅ΡΠΊΡƒΡŽ ΡΠΌΠ΅Ρ€Ρ‚ΡŒ ΠΎΡ‚ острой ΠΊΡ€ΠΎΠ²ΠΎΠΏΠΎΡ‚Π΅Ρ€ΠΈ.

    Objective. To prove pathogenically the reasonability of multimodal anesthesia in patients with lung cancer toΒ improve the efficacy of pain management.Materials and methods. 74 patients (59 men and 15 women) aged 46 to 60 years with lung cancer were examined and treated. 42 patients (the main group) underwent surgery under multimodal anesthesia accompanied withΒ epidural blockade, and 32 patients (the comparison group) were subjected to a surgical intervention under inhalation and intravenous anesthesia with mechanical ventilation. The surgeries including atypical lung resection,Β lobectomy and pneumonectomy were performed. In preoperative, intraoperative and early postoperative periods,Β the systemic hemodynamics parameters were determined; adrenaline, noradrenaline, dopamine, cortisol, insulinΒ and glucose were measured in plasma, and acidbase balance parameters β€” in arterial blood. Pain intensity wasΒ assessed by the visual analog scale. Data processing was carried out using Microsoft Exсel 2000, STATISTICA6.0Β and Biostat software. Normality of distribution was assessed by KolmogorovSmirnov test. Since the ordered sample did not follow the normal distribution law, the data are presented as a median (Me) and interquartile amplitude (25 and 75 percentiles).Results. It has been found that the most significant pathogenic factor in patients being operated due to lungΒ cancer under the standard anesthesia is the expressed activation of the sympathoadrenal system due to the impactΒ of surgical stress. This is manifested by disorders of the central hemodynamic parameters, such as metabolism,Β nociception and oxygen balance. In surgeries carried out under multimodal anesthesia, the minimal changes ofΒ basic homeostasis parameters are registered; these changes are shorttermed, compensated and reversible. PainΒ syndrome upon completion of surgery and in the early postoperative period is either absent or mild.Conclusion. It is more expedient to perform surgeries to remove malignant tumors in the lungs under the multimodal anesthesia, because these interventions are distinguished by high traumatic rate and having a Β«fine lineΒ» between compensation and decompensation of the basic vital functions in the perioperative period.ЦСль исслСдования β€” патогСнСтичСски ΠΎΠ±ΠΎΡΠ½ΠΎΠ²Π°Ρ‚ΡŒ Ρ†Π΅Π»Π΅ΡΠΎΠΎΠ±Ρ€Π°Π·Π½ΠΎΡΡ‚ΡŒ использования ΠΌΡƒΠ»ΡŒΡ‚ΠΈΠΌΠΎΠ΄Π°Π»ΡŒΠ½ΠΎΠΉΒ Π°Π½Π΅ΡΡ‚Π΅Π·ΠΈΠΈ Ρƒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… со злокачСствСнными новообразованиями Π»Π΅Π³ΠΊΠΈΡ… для ΠΏΠΎΠ²Ρ‹ΡˆΠ΅Π½ΠΈΡ эффСктивности обСзболивания.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
