Clinical guidelines «Sepsis (in adults)» are an interdisciplinary document developed by 8 professional non-profit public organizations and approved by the Scientific and Practical Council of the Ministry of Health of Russia. They are intended to help doctors of various specialties (anesthesiologist and intensivist, surgeon, emergency physician, neurosurgeon, cardiovascular surgeon, thoracic surgeon, transfusiologist, orthopedic traumatologist, nephrologist, urologist, maxillofacial surgeon, infectious disease physician, clinical pharmacologist, medical microbiologist) in determining the treatment strategy and tactics for patients with sepsis or at risk of its development. The material presented to the reader’s attention reflects the main provisions of the document that are important for practical work. Its full content can be found on the websites of the Ministry of Health (https://cr.minzdrav.gov. ru/) and the public organizations (in particular, https://association-ar.ru/; https://общество-хирургов.рф/; https://sepsisforum.ru/; https://www. antibiotic.ru/) that developed them. In terms of their main provisions, the recommendations correspond to the latest international guidelines (Surviving sepsis campaign from 2021), but take into account the specifics of the work of medical organizations in the Russian Federation. These recommendations apply to the following codes of the International statistical classification of diseases and problems related to adult health: A40 – streptococcal sepsis (A40.0/A40.1/A40.2/A40.3/A40.8/A40.9); A41 – other sepsis (A41.0/A41.1/A41.2/A41.3/A41.4/A41.5/A41.8/41.9) and B37.7 – candidal septicemia.

In cardiac surgery with cardiopulmonary bypass (CPB) is a common complication. The incidence of this complication in cardiac surgery patients is estimated at about 10%. For this reason, the introduction of a patient blood management (PBM) in cardiac surgery is extremely relevant. Antifibrinolytic therapy is a key pharmacological tool of a multimodal PBM in cardiac surgery with CPB. The use of antifibrinolytics (tranexamic acid (TXA) and epsilon aminocaproic acid (EACA)) is standard practice in complex cardiac surgery with CPB. However, there is currently ongoing discussion regarding the search for the optimal dose of EACA and TXA to achieve an effective concentration in blood plasma in order to inhibit fibrinolysis with the minimization of adverse events. The use of aprotinin has a number of potential advantages, but its use in routine clinical practice is significantly limited. This review presents modern approaches to antifibrinolytic therapy, examines the mechanisms of action of the main drugs, highlights the side effects associated with the use of antifibrinolytic agents.

Fluoroscopy guided epidural injection is often used to treat radicular pain in the lumbar spine. Risk and effectiveness data vary depending on injection routes and underlying pathology. There are several options for accessing the epidural space in the lumbosacral spine to perform an analgesic injection – caudal, interlaminar and transforaminal. Transforaminal epidural injection is currently the most studied and widespread in the foreign practice of treating chronic pain. A brief overview describes transforaminal accesses to the epidural space of the lumbar spine and needles used for this purpose, lists possible adverse events and complications, and also provides a detailed illustrated description of supraneural transforaminal access.

The objective: Comparison of parameters characterizing the operation of the pressure support regime on modern anesthetic and intensive care ventilators.Subjects and Methods. The study included 5 anesthesia machines (Mindray WATO EX-65, Drӓger Primus, GE Avance S/5, GE Carestation 650, and GE Aisys CS2) and 5 intensive ventilators (Hamilton C1, Hamilton C2, GE Engstrӧm Carestation, Puritane Bennette 840, and Puritane Bennette 980). All devices were tested using the Ingmar medical ASL 5000 breathing device. The trigger delay time, the maximum pressure reduction below the PEEP level at the initiation of inspiration, PTP (pressure-time product), as well as the level of pressure achieved after 300 and 500 ms from the start of inspiration at different levels of pressure support and PEEP were evaluated.Results. The parameters characterizing operation of the trigger system and pattern of the inspiratory pressure set in ventilators used in intensive care and anesthesia ventilators had statistically significant differences. However, in terms of the response rate of the trigger system, modern anesthesia machines (GE Avance S/2, GE Caretation 650, and GE Aisys CS2) are not significantly inferior to traditional ventilators, their trigger delay time is about 100 ms. The maximum decrease in pressure below PEEP before the start of inhalation in the tested intensive ventilators was 1.0–1.5 cm H2O, in modern anesthesia machines this parameter was comparable and made approximately 1.5–2.0 cm H2O (GE Avance S/2, GE Caremation 650, and GE Aisys CS2). Assessment of the pressure level achieved after 300 and 500 ms showed that these parameters were closer to the target pressure for ventilators of the pneumatic compressor design, for turbine devices these parameters were approximately 25% less. Anaesthesia devices with a two-circuit pneumatic design had 40% less pressure values compared to devices with a pneumatic compressor design.Conclusion: The performance of the trigger system in modern anesthesia and intensive care ventilators does not differ significantly. Most of the anesthesia machines tested did not reach the target pressure within 500 ms, and by this parameter they differ significantly from intensive care respirators.

The epidural anesthesia has found widespread application in abdominal surgical interventions. But the relevance of its use is the subject to some doubt and discussion in connection with developing surgical technologies and reduction of the degree of surgical aggression, and introduction of new approaches to the management of patients in the perioperative period. Often the risks of epidural anesthesia exceed expected benefits. This is a limiting factor for its use. Today, there is no uniform approach to the way epidural analgesia is administered in the intraoperative period. However, there is a correlation between the frequency of adverse events related to epidural block and the route of administration (speed of administration, volume, and concentration).Therefore, selecting the optimal method of epidural analgesia within the framework of combined anesthesia can minimize the risks and maximize its positive effects in abdominal surgery.

The objective: to analyze the contemporary specific parameters of intraoperative management of epidural analgesia (EA) in combined anesthesia in abdominal oncological surgeries in different medical organizations of Russia.Subjects and Methods. The data necessary for analysis and statistical processing were obtained by developing a formalized questionnaire (21 questions, some of which with the possibility of choosing several answers at the same time – multiple choice), published on the official website of the Association of Anesthesiologists-Resuscitators (https://association-ar.ru/). The survey lasted for 16 days (from May 23, 2022 to June 7, 2022). The survey results were collected using the Google Forms online service and processed using the Google Spreadsheets. Multiple choice responses were processed as absolute numbers and presented as a percentage of the total number of responses to a particular question.Results. The total number of respondents who took part in the survey was 217 specialists from various medical organizations, mostly from the North-Western Federal District of the Russian Federation (34.1%) with more than 15 years of expertise in the specialty (44.7%). According to the survey results, the following specific features of EA during combined anesthesia practice in Russia have been identified: most participants perform EA in the sitting position (63.6%); ropivacaine is the drug of choice among local anesthetics (LA) (84.2%); as a rule, EA is initiated prior to incision (69.6%). During open surgical interventions, 44.7% use a combined EA method (continuous infusion and bolus injection – bolus-based mode), while during laparoscopic surgeries there is no preferred method (combined method – 33.1%; continuous infusion only – 35.5%; bolus injection only – 31.4%). Low concentrations of LA (0.2 ‒ 0.375%) combined with a low volume of administration (4‒10 ml for bolus, 4‒8 ml/h for infusion) are used more often both in open and laparoscopic surgeries. In most cases, achievement of effective EA is supported by lower doses of systemic opioid analgesics (65.4%). Insufficient degree of intraoperative analgesia is managed in different ways, such as using systemic opioids (68.7%), enhancing epidural analgesia (17.5%), and administration of non-opioid analgesics (13.8%).Conclusion. At present, there is no unified approach to the method of EA in combined anesthesia. The results of the survey showed the uncertainty of experts' opinions regarding the choice of LA concentrations for EA, the rate and volume of its administration into the epidural space. Finding the optimal method of intraoperative EA in abdominal oncological surgery is the most important clinical objective in terms of reducing perioperative complications.

It is believed that microcirculation dysfunction in sepsis primarily caused by damage of the endothelium by infectious agents and pro-inflammatory cytokines. Mechanisms of impaired microcirculation in the severe course of COVID-19 and sepsis likely to be similar. However, there are few reports studied microcirculation disorders in patients with COVID-19, and their results are sometimes contradictory. Objective. To assess the microcirculation of patients with severe Covid-19 and the development of bacterial sepsis using nail bed microscopy and laser Doppler flowmetry. Materials and methods. 16 intensive care unit COVID-19 patients subsequently diagnosed with bacterial sepsis were examined. Patients underwent vital capillaroscopy and an occlusive test using laser Doppler flowmetry. The average rate of capillary blood flow, the size of the perivascular zone, the density of capillaries, the presence of intravascular aggregates, the increase in the amplitude of the maximum post-occlusive blood flow and the average value of postocclusive blood flow relative to the initial one were valuated. Additionally, the level of serum proadrenomedullin was evaluated. Studies were performed on the day of admission and in dynamics. Results. By the capillaroscopy analysis, microcirculation disorders were detected in the form of a decrease in the linear speed of capillary blood flow (<400 μm/s), an extention of the perivascular zone (>100 μm), the circulation of microaggregates; the absence of postocclusive hyperemia was determined by an occlusive test. Secondary bacterial infection led to an even greater aggravation of microcirculation disorders: an increase of the perivascular zone, the progression of intravascular aggregation resulting in microthrombosis with a decrease of the density of the capillary network (according to capillaroscopy), as well as a sharp decrease of amplitude maximal increment of blood flow of post-осclusive circulation at the time of an occlusive sample. We also revealed a trend of negative correlation between the level of serum proadrenomedullin and the maximum increase in blood flow during the occlusive test. Conclusion. The secondary bacterial infection in patients with COVID-19 leads to a significant aggravation of microcirculation disorders with the development of perfusion deficiency and interstitial edema. The increased plasma proadrenomedullin level supports the concept of the significant role of endothelial dysfunction in the pathogenesis of severe COVID-10 and bacterial sepsis.

The objective: to compare effectiveness of pressure support and mandatory ventilation modes at the final stage of general anesthesia.Subjects and Methods. 58 patients were included in the study. All patients underwent laparoscopic or open surgery under combined general anesthesia with muscle relaxants and tracheal intubation. At the end of the operation, after suturing the muscle layer, patients were randomly divided into two groups, depending on the further mode of ventilation: the mandatory mode group with dual control until extubation (n = 29) and the spontaneous breathing mode group with pressure support (n = 29). The time of awakening, the severity of post-extubation cough, hemodynamic parameters and oxygenation immediately before and 5 minutes after extubation were assessed.Results. In the groups of patients, statistically significant differences were observed in the time of awakening (252 ± 67 sec and 426 ± 71 sec in PSV and PCV-VG Groups, respectively), extubation (287 ± 55 sec and 464 ± 67 sec in the PSV and PCV-VG groups, respectively), and transfer from the operating room (473 ± 60 sec and 687 ± 77 sec in the PSV and PCV-VG groups, respectively) (p < 0.0001). Also, patients receiving PSV respiratory support had higher saturation levels 5 minutes after extubation (p < 0.0001), and heart rate and mean arterial pressure immediately before extubation were lower than in the mandatory ventilation group (p = 0.013 and p < 0.0001, respectively). In addition, in the mode of spontaneous breathing with pressure support, a lower severity of post-extubation cough was observed (p = 0.003).Conclusion. The use of a spontaneous breathing mode with pressure support at the end of general combined anesthesia has several advantages versus mandatory ventilation mode. These advantages include faster awakening, extubation and transfer of the patient to the ward, lower severity of post-extubation cough, as well as better gas exchange after extubation, lower intensity of hypertension and tachycardia before it.

To compare efficacy of spontaneous breathing with pressure support and volum e-c ontrolled mandatory ventilation during combined general anesthesia using desflurane and without muscle relaxants. Subjects and Methods. 100 patients were included in the study. All underwent lo w-t raumatic operations on the lower limbs under general combined anesthesia using supraglottic air devices without muscle relaxants. Immediately prior to the induction of anesthesia, patients were randomly divided into two groups: Group 1 ( VCV ) where a mandatory volume control mode was used ( n = 50) and Group 2 ( PSV ) where a pressure support mode was used ( n = 50). The following parameters were assessed: hemodynamics, gas exchange, depth of anesthesia before induction, during and after the end of general anesthesia; arterial blood gas composition one hour after induction of anesthesia; indicators of pressure in the respiratory tract during mechanical ventilation, as well as time parameters of awakening. Results. In patients of Group 2 ( PSV ), according to the analysis of arterial blood gases, a higher level of PaO 2 ( p = 0.006), Horowitz index ( p = 0.005), and carbon dioxide level ( p < 0.0001) were noted. In Group 1 ( VCV ), higher mean and peak airway pressures were found one hour after induction and 10 minutes before the end of surgery ( p < 0.05). Also in the groups, there were statistically significant differences in the time parameters of awakening (233 ± 58 sec and 352 ± 83 sec in the PSV and VCV groups, respectively), supraglottic airway device removal time (268 ± 62 sec and 398 ± 84 sec in the PSV and VCV groups, respectively) and transfer to the ward (395 ± 60 sec and 571 ± 66 sec in the PSV and VCV groups, respectively) ( p < 0.0001). There were no significant differences in the main parameters of hemodynamics and depth of anesthesia, the consumption of anesthetics used during induction and maintenance of general anesthesia. Conclusion: The use of spontaneous breathing with pressure support during general combined anesthesia without muscle relaxants has a number of advantages versus mandatory ventilation mode. These include better oxygenation rates, lower airway pressure, faster awakening, supraglottic airway device removal time, and transfer of the patient to the ward. At the same time, acceptable ventilation, stable hemodynamic parameters and depth of anesthesia are maintained.

The objective: choosing the optimal method of epidural analgesia combined with general anesthesia for typical laparoscopic colorectal surgeries by comparing three different options for its implementation. Subjects and Methods. 90 patients aged 60 to 85 years were examined, they all underwent planned laparoscopic interventions for colorectal cancer under combined anesthesia (general + epidural anesthesia). Depending on the method of administration of ropivacaine to achieve an epidural block, they were randomized into three groups. In Group 1, it was administered at a concentration of 0.25% in the form of a continuous infusion at a rate of 8 m l/h during the first hour, then 6 ml/ h until the end of the operation. In Group 2, its concentration was increased to 0.375%, the rate of continuous infusion was 8 ml/ h in the first hour, then 6 m l/h . Patients of Group 3 first received ropivacaine as a bolus before the induction of general anesthesia (0.375% – 8 ml over 5 min), then continued administration continuously but at a concentration of 0.25% at a rate of 6 m l/h . Endpoints for hemodynamic assessment: upon admission to the operating room, after induction of anesthesia, after application of carboxyperitoneum, after 1 hour of laparoscopic stage, after elimination of carboxyperitoneum, after extubation, and 1 hour after transfer to the ICU . The total dose of fentanyl was recorded. The assessment of the sensory block was performed using a cold test, the severity of the pain syndrome ‒ on a visua l-a nalog scale (10 points), the density of the block ‒ on an ordinal scale, its upper and lower levels were noted. The motor block was evaluated using a modified Bromage scale. Results. The doses of fentanyl, rocuronium and the consumption of desflurane during general anesthesia, the values of the BIS index and the time of awakening of patients in all groups did not differ. The average doses of ropivacaine in the groups were different. The total volume of ropivacaine solution was the largest in Group 3, there were no significant differences in the volume of the injected local anesthetic between Group 1 and Group 2. The number of patients who needed vasopressor support with norepinephrine during anesthesia in Group 1 was less versus Groups 2 and 3. The maximum intraoperative dose of norepinephrine and duration of its use were also lower in Group 1. When applying carboxyperitoneum, the most pronounced decrease in hemodynamic parameters was revealed in patients of Group 3. At the 4th stage of the study, after 1 hour of the laparoscopic stage, hemodynamic parameters were higher in patients of Group 1. There were no significant differences in pain intensity between the groups after surgery. At the same time, the level of motor block was significantly higher in patients of Group 2, while in Groups 1 and 3, motor block did not develop in most of the patients. Conclusion: The optimal method of epidural analgesia in typical laparoscopic colorectal operations is the use of 0.25% ropivacaine concentration as a continuous infusion only due to ensuring an acceptable level of analgesia, adequate distribution of the sensory block, the minimum degree of motor block, as well as the least negative effect on hemodynamic parameters which reduces the volume of infusion therapy and doses of vasopressors.

The article describes a clinical case when a patient who was supposed to have a planned surgery on the spine developed anaphylactic shock. After 10 minutes of anesthesia introduction, the patient developed severe hypotension (resistant to the administration of adrenomimetics) and tachycardia; a decrease in the partial pressure of carbon dioxide at the end of expiration was noted. Due to the rapid development of a critical condition, the absence of specific skin manifestations and allergic history, as well as a direct association with the administration of a specific agent, it was necessary to carry out a differential diagnosis between acute myocardial infarction, pulmonary embolism, and anaphylactic shock. During the intensive care, the patient had echocardiography and ECG, blood gases were tested; the decisive diagnostic factor was the identification of bronchospasm signs. When the condition was stabilized, angiography of the vessels of the heart and lungs was performed; later, the agent that caused the development of anaphylaxis was established.Identifying the cause of hypotension after induction of anesthesia is critical because therapy can vary significantly. The development of anaphylactic shock during general anesthesia is not common but delayed diagnosis and therapy can be fatal. The article discusses modern approaches to the diagnosis and therapy of perioperative anaphylaxis using the example of the presented clinical case.

Microcirculation disorders caused by thrombosis are the most important factor determining the pathogenesis of organ damage in severe COVID-19 including the absence of obvious macrohemodynamic instability. However, there are very few publications demonstrating the results of intravital visualization of changes in the microcirculation system in this disease.The objective:to assess the state of microcirculation in patients with viral pneumonia associated with COVID-19 using nail bed microscopy.Subjects and methods.Eleven patients with COVID-19 were examined; they were admitted to the intensive care unit due to progressing acute respiratory failure. Vital microscopy of the microcirculatory bloodstream in the fingers’ nail bed was performed by admission and over time. When assessing microcirculation, the presence of aggregates in the lumen of capillaries and avascular zones, and the linear velocity of blood flow were taken into account. The results were summarized taking with the outcome consideration (6 people recovered, 5 died).Results.Microcirculation disorders were objectively confirmed in all patients. In 100% of cases, microaggregates were detected in the capillary lumen. The values of the mean linear velocity of capillary blood flow turned out to be extremely variable. However, the values of the maximum linear velocities of capillary blood flow in the patients who subsequently died were significantly lower versus survivors (190 μm/sec (135.5; 237) and 387 μm/sec (329.3; 407.5), p = 0.018). The irregularity of blood flow in the visualized field was revealed: when the value of the maximum linear velocity in some capillaries was less than 180 µm/sec, in others, disturbances in the form of pendulum-like movement were already noted. Further slowing down of the blood flow velocity led to the development of stasis and the formation of avascular zones.Conclusion.Impaired microcirculation (decreased blood flow rate in the capillaries, the presence of microaggregates and a lower number of perfused capillaries in the form of avascular zones) develops in all patients with severe COVID-19.

Impaired microcirculation due to endothelial dysfunction in COVID-19 is considered to be the most important link in the pathogenesis of this disease. However, due to the complexity of its instrumental assessment in critically ill patients, the data available in the literature on specific manifestations of endothelial dysfunction are very contradictory.The objective: to determine the most characteristic capillaroscopic signs of microvascular disorders and to assess the state of microcirculation regulation in patients with severe COVID-19.Subjects and Methods. When admitted to the intensive care unit, 60 patients with COVID-19 and 12 patients with chronic cardiovascular pathology without COVID-19 (Comparison Group) were examined. All patients underwent microscopy of the microcirculatory bed of finger nail bed; the following parameters were assessed: diameters of the venous, arterial and transitional parts of capillaries, height of capillary loops, density of capillaries per 1 mm of the length of the perivascular zone, the average linear velocity of capillary blood flow (LVCBF), and thickness of the perivascular zone. The presence of avascular zones, the number of capillaries in the visualized field with circulating aggregates in the lumen, and the shape of capillaries were taken into account. In addition, an occlusion test using laser Doppler flowmetry was performed in 32 patients with COVID-19. The maximum post-occlusive increase in blood flow at the moment of cuff deflation was assessed, as well as changes in the mean value of post-occlusive blood flow relative to the baseline within 3 minutes after cuff deflation.Results. In 53 (88.3%) patients with COVID-19, abnormalities corresponding to chronic microcirculatory changes in the form of predominance of pathological capillary forms were detected. Microaggregates in the lumen of capillaries and decreased linear velocity of blood flow were revealed in 100% of cases. When comparing groups of patients with different outcomes, statistically significant differences were revealed between the LVCBF parameters (in the survivors - 354.35 ± 44.78 pm/sec, in the deceased - 278.4 ± 26.59 pm/sec), as well as between the values of the perivascular zones thickness (95.35 ± 15.96 microns versus 159.93 ± 19.90 microns). The results of the post-occlusion test revealed a significant difference between the groups in terms of the maximum post-occlusion gain (39.42 ± 3.85 BPU in the group with a favorable outcome, 27.69 ± 3.19 BPU in the group with an unfavorable outcome, 47.23 ± 1.78 BPU in the control group). In both groups, there was no increase in this parameter relative to the initial blood flow. At the same time, in the control group, the average index of post-occlusive blood flow was higher than the initial level.Conclusions. Acute microcirculation disorders with decreased linear velocity of capillary blood flow, circulation of aggregates, increased thickness of the perivascular zone were detected in all patients with severe COVID-19 but especially in those with unfavorable outcomes. Vascular tone regulation disorders were manifested by the absence of reactive hyperemia in response to acute ischemia, as well as a decrease in maximal flow-induced increase. These changes fit into the concept of endothelial dysfunction. Signs of chronic microcirculation disorders in most patients increase the risk of severe COVID-19.

The objective: basing on published data, to highlight the main issues of preparation of patients with concomitant lung pathology and a high risk of developing postoperative pulmonary complications for planned surgical interventions. Results: changes made to international guidelines over the past 5 years based on evidence-based studies and meta-analyzes have been analyzed. The article presents data on preoperative management of patients with concomitant lung pathologies and a high risk of postoperative pulmonary complications, assessment of the risk of developing these complications based on evaluation of the functional status of patients. It analyzes the contemporary recommendations on the perioperative prevention of pulmonary complications, the use of physical exercises and respiratory gymnastics in the perioperative period in patients with a high risk of postoperative pulmonary complications. It is concluded that the implementation of comprehensive strategy aimed at reducing the risk of pulmonary complications should ensure decrease in their frequency and mortality due to them.

technique relevance. The healthy volunteers showed the typical patterns of slow wave part of ACS in the upper and lower parts of the body in clinostatic and orthostatic positions. The body position changing is reversing the patterns in the upper and lower body parts. Getting the postural test allows to assess the integrity of regulation mechanisms of microcirculation. The method used and the results need further investigation to determine the possibility to detect the functional and pathological changes, as well as compensatory possibilities of microcirculation in normal and in pathology.

Hypercalcemic hyperparathyroid crisis is a rare and potentially life threatening manifestation of primary hyperparathyroidism. The article describes a clinical case of a 66-year old female patient who developed hypercalcemic hyperparathyroid crisis after neurosurgical intervention. Computed tomography used for targeted diagnostics detected parathyroid adenoma of the ectopic localization. The conservative therapy failed and the surgery was indicated - thoracoscopic excision of adenoma. This clinical case illustrates the contemporary approaches to diagnostics and management of this disorder.

The review describes modern approaches to pain relief in the patients after total knee and hip replacement. It covers the principles of mult i-m odal analgesia, benefits and drawbacks of such ways of pain relief as intravenous analgesia with opioids, spinal and epidural analgesia; it compares different variants of peripheral blocks, and puts some light on a relatively new method of local periarticular infiltration anesthesia. The authors agree that further research is needed to optimize pos t-o perative pain relief after total knee and hip replacement.

Portal venous gas is a relatively rare case in clinical practice. Initially, the development of portal venous gas was associated with the life-threatening intra-abdominal disorder, which as a rule required emergency surgery. Introduction of new achievements in diagnostics resulted in the more frequent registration of portal venous gas in various abdominal disorders and after invasive surgery. A large volume of gas can result in the portal obstruction with development of portal hypertension and portal-systemic anastomoses. Gas can migrate from portal vein into system venous blood flow through liver or portal-systemic anastomoses in case of no abnormality, and cause pulmonary gaseous embolism which can be followed by arterial embolism. The article presents the clinical case of the patient suffering from pancreatic gland tumor, in whom portal venous gas followed by arterial embolism was detected in the post-operative period.

The article describes the clinical case when malignant hyperthermia was diagnosed in the patients during the cardiac surgery. The patient had anesthesia with desflurane. The state of the patient was stabilized due to timely diagnostics and aggressive therapy with non-specific agents and cardiopulmonary bypass. The article presents different variants of clinical manifestations of this complication, ways of diagnostics and specific therapy.
