To present the experience in a new approach for the surgical treatment of cicatricial cervical tracheal stenosis — tracheal resection without using an endotracheal tube. Methods. The technique includes preliminary metal stent placement instead of bougienage in the stenosis zone; introduction of the supraglottic airway device I-Gel instead of the endotracheal tube and; jet ventilation through the supraglottic airway device. The stent is removed together with the resected trachea. The technique of cervical tracheal resection using the supraglottic airway device was implemented in 22 patients with cicatricial tracheal stenosis. Results. The resection length ranged from 15 to 45 mm (on average, 27±3 mm). The duration of surgical interventions ranged from 65 to 180 minutes (on average, 109±9 minutes). Preliminary stenting excluded preoperative bougienage of the trachea and facilitated intraoperative assessment of the extent of the stenosis. The absence of an endotracheal tube facilitated the formation of anastomosis of the trachea, eliminated the risk of trauma to the anastomosis during tube removal. There were no complications in the early postoperative period. The length of postoperative hospital stay ranged from10 to 14 days (on average, 12±2 days). No restenosis was detected at long term follow-up. Conclusion. Performing tracheal resection without intubation allows the surgeon to work comfortably, observing the safety conditions for ensuring airway patency throughout the operation by installing a supraglottic airway device.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83370359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined 110 patients with rhinosinusitis and 30 healthy donors (control group). The patients were divided into the group without a complicated course of rhinosinusitis (first group, n=65) and the group with a complicated course of rhinosinusitis (second group, n=45). The blood serum levels of interleukin (IL)-1, IL-4, IL-8, IL-10, IL-17, IL-18, interferon (IFN)- were determined by enzyme immunoassay. Statistical analysis of the results was performed by using Microsoft Excel 2013 and Statistica 12.0 software. Statistically significant differences between the compared groups were determined by using the MannWhitney U-test, and p 0.05 was considered significant. Multivariate analysis included correlation analysis and stepwise regression analysis.

The study included 76 patients with stable heart failure I–IV functional class, with a mean age of 66.1±10.4 years. All patients were divided into 3 subgroups based on the left ventricular ejection fraction: the first group — heart failure patients with reduced ejection fraction (below 40%), 21.1%; the second group — patients with mid-range ejection fraction (from 40 to 49%), 23.7%; the third group — patients with preserved ejection fraction (>50%), 55.3%. The clinical characteristics of all groups were compared. The quality of life was assessed by the Minnesota Satisfaction Questionnaire (MSQ), the clinical condition was determined by using the clinical condition assessment scale (Russian “Shocks”). The prognosis was studied according to the onset of cardiovascular events one year after enrollment in the study. The endpoints were cardiovascular mortality, myocardial infarction (MI), stroke, hospitalization for acutely decompensated heart failure, thrombotic complications. Statistical analysis was performed by using IBM SPSS Statistics 20 software. Normal distribution of the data was determined by the Shapiro–Wilk test, nominal indicators were compared between groups by using chi-square tests, normally distributed quantitative indicators — by ANOVA.

Patients with cirrhosis of the liver often notice chest pain, palpitations, complaints of arterial hypotension and rapid fatigue. Echocardiography shows that the left ventricular ejection fraction in cirrhosis is preserved at rest and decreases under stress. In some patients with viral liver cirrhosis, there is a decrease in global myocardial deformation (the presence of latent systolic dysfunction). More pronounced impairment of left ventricular diastolic function is recorded in patients with ascites and patients with ChildPugh class B and C. In patients with ascites, unfavorable left ventricular remodeling, left heart cavities enlargement, dilatation of the pulmonary artery and its branches are more common. There is an increase in pulmonary artery pressure, the development of portopulmonary hypertension and hepatopulmonary syndrome in patients with liver cirrhosis. Тhe development of these syndromes leads to a sharp decrease in the quality of life of patients with relatively preserved liver function and a worsening of the prognosis for orthotopic liver transplantation. Аpproximately half of patients with liver cirrhosis have electrophysiological disorders: prolongation of the QT interval, tachycardia, supraventricular and ventricular extrasystoles. To date, there are no clinical guidelines for the management of cirrhotic cardiomyopathy. If a patient with liver cirrhosis develops clinically significant heart failure, then general principles of management of such patients are necessary. It is necessary to limit the use of angiotensin-converting enzyme inhibitors and cardiac glycosides. The combined use of nonselective beta-blockers and nitrates reduce cardiac output and QT interval. The use of potassium canrenoate, lisinopril helps reverse the development of structural and functional changes in left ventricle. The positive effect of antiviral therapy on cardiac hemodynamics in patients with viral cirrhosis was noted. Liver transplantation is known to be an effective treatment for cirrhotic cardiomyopathy, but this treatment may worsen latent heart failure. Thus, in patients with liver cirrhosis, heart damage occurs with the development of cirrhotic cardiomyopathy, while the mechanisms of the development of myocardial dysfunction are not fully understood. Further studies of the development of the syndrome are required for timely diagnosis and clinical intervention to improve the survival of patients.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75941962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments were carried out on laboratory rats weighing 140180 g. The animals were divided into two groups: Control (8 rats) and Spinal shock (6 rats). The lower leg muscles, m. soleus and m. extensor digitorum longus (m. EDL), were dissected by partially isolating without disrupting the connection with the body's circulatory system. The sciatic nerve was stimulated with single electrical impulses (10 V, 0.5 ms). Contractions of both muscles caused by electrical stimulation of the sciatic nerve before and after the injection of the substances into the femoral artery tubocurarine (1 mM) or norepinephrine (10 mM) were recorded in animals of both groups. After spinalization, muscle contractions were re-recorded during electrical stimulation of the sciatic nerve before and 10 minutes after the injection of tubocurarine or noradrenaline into the femoral artery in the same concentrations. \u0000Results. After spinalization of the animal, the contraction force of the muscle m. EDL fibers increased to 0.430.03 g (p=0.040), but the temporal parameters remained unchanged. M. soleus, on the contrary, showed a decrease in the contraction time to 0.0530.005 s (p=0.045), and no change in the contraction force was observed under these conditions. Intra-arterial administration of norepinephrine in the control group resulted in an increase of m. soleus contractions up to 1.210.17 g (p=0.048), and m. EDL up to 0.570.07 g (p=0.043). The administration of norepinephrine in spinalized animals caused an increase in the contraction of m. soleus up to 1.210.09 g (p=0.047), and m. EDL up to 0.660.05 g (p=0.043).

Experts reached an agreement on the definition of diagnostic criteria for small-for-gestational-age fetus and fetal growth restriction, a clinically valid classification was created, and the main monitoring strategies were developed. Due to the different pathogenesis, fetal growth restriction is divided into early and late. The observation algorithm includes tests that have shown higher sensitivity and specificity. There is no single standard for the median weight and abdominal circumference of a fetus, indicators of the reference range for fetal Doppler. Smoking cessation and taking acetylsalicylic acid at a dose of 150 mg at high risk of preeclampsia is recommended to prevent the small-for-gestational-age fetus and fetal growth restriction. The pregnancy management algorithm includes Doppler ultrasound examination of the umbilical artery, cardiotocography. If this pathology occurs before 32 weeks of pregnancy, the blood flow in ductus venosus is additionally examined, and after 32 weeks of pregnancy, the middle cerebral artery blood velocities and cerebroplacental ratio are assessed. Indicators of Doppler velocimetry and cardiotocography, which serve as criteria for early termination of pregnancy, are developed, measures are proposed to improve neonatal outcomes — prevention of respiratory distress syndrome at 24–34 weeks of gestation, as well as magnesium therapy for fetal neuroprotection. The problems of preventing fetal growth restriction and the algorithm for monitoring pregnant women who do not have risk factors for small-for-gestational-age fetus, management tactics and indications for delivery while slowing fetal weight gain remain unresolved.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90084317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the effect of meglumine sodium succinate on the effectiveness of basic therapy in correcting gas exchange abnormalities in patients with severe COVID-19 infection complicated by bilateral community-acquired pneumonia. Methods. The analysis of the effectiveness of therapy of 12 patients with a diagnosis of \"New coronavirus infection COVID-19 (confirmed), severe form U07.1. Complication: Bilateral multifocal pneumonia\" was carried out. The patients were divided into two groups: 7 received, as part of standard therapy, a solution of meglumine sodium succinate in a daily dose of 5 ml/kg during stay in the intensive care unit;5 patients received a similar volume of Ringer's solution and formed the control group. In the arterial and venous blood of all patients, the indicators of acid-base state and water-electrolyte balance, glycemia and lactatemia were measured at several stages: (1) at admission to the intensive care unit, (2) 2-4 hours after the start of intensive therapy, (3) after 8-12 hours, (4) after 24 hours. On the 28th day of observation, mortality, the duration of treatment in the intensive care unit and the incidence of thrombotic complications in the groups were assessed. The Friedman nonparametric hypothesis test was used to assess intragroup dynamics, and the nonparametric Mann-hitney U test for intergroup comparisons. Results. In the group of patients who received meglumine sodium succinate, there was a significant decrease in the incidence of thromboembolic events during 28 days of treatment: Myocardial ischemia event rate ratio from 0.89 [95% confidence interval (CI) 0.19-1.16] in the control group to 0.55 (95% CI 0.06-0.81) in the study group at p=0.043;pulmonary embolism event from 0.50 (95% CI 0-1.0) in the control group to 0.28 (95% CI 0-1.0) in the study group at p=0.041. There was also a decrease in the duration of intensive care unit length of stay to 6.1±1.1 days in the study group versus 8.9±1.3 days in the control group. Conclusion. Compared with standard infusion therapy, the use of meglumine sodium succinate leads to a faster normalization of ventilation-perfusion ratios in patients with severe coronavirus infection. © 2021 Eco-Vector LLC.
