Aim. Substantiation of cisatracurium dosing in routine gynaecological laparoscopic surgery in obese patients based on comparative development time and duration of the neuromuscular block.Materials and methods. The assay included 24 women with class II-III obesity and routine laparoscopic gynaecological surgery divided into two cohorts. In cohort 1, cisatracurium was dosed at 0.15 mg/kg ideal body weight estimated with the Lorentz formula. In cohort 2, cisatracurium dosing was 0.15 mg/kg real body weight.Results. Tracheal intubation and total operation doses of the relaxant were higher when rated for real body weight. Time between cysatracurium administration and maximal neuromuscular transmission inhibition was less in cohort 2, and recovery time of the first response to stimulation — in cohort 1. Neuromuscular block recovery time to 25% TOF count and the recovery index did not differ significantly between the cohorts.Conclusion. Cysatracurium dosage rated for ideal body weight resulted in a better controlled course of the neuromuscular block, whilst rating for real body weight resulted in a dose-dependent increase of the duration of action and total consumption rate of the relaxant.

Aim. To study the characteristics of direct oral anticoagulant-related bleeding in patients with heart failure in combination with chronic obstructive pulmonary disease (COPD) and atrial fibrillation. To show the efficacy of idarucizumab in complex therapy of severe gastrointestinal bleeding caused by dabigatran. Material and methods. The single-center prospective observational study included 150 patients with nonvalvular atrial fibrillation treated with direct oral anticoagulants. Of these patients, 75 had heart failure in combination with COPD (experimental group) and 75 — HF without comorbidities (comparison group). Groups were formed by propensity score matching. Sex, age, bleeding risk by HAS-BLED score were covariates. HF was diagnosed in accordance with the criteria applied by Russian Federal clinical guidelines. COPD was diagnosed according to GOLD 2011-2020 criteria. Frequency of all bleeding, major bleeding, bleeding into critical organs were evaluated. Follow-up period was 14 (12; 16) months. Cox regression method was used to determine relationships. Results. Annual rate of major bleeding in group of HF and COPD was higher (Hazard ratio (HR) 3,0, 95% confidence interval (CI) 1,1-6,2, р =0,02), regardless of which anticoagulant was used. Gastrointestinal bleeding occurs in 7 (9,3%) and 2 (2,7%) patients (HR 3,5, 95% CI 1,1-7,3, р =0,05). In subjects with comorbidity, major and gastrointestinal bleeding were associated with partial pressure of arterial oxygen (HR 0,89, 95% CI 0,55-0,95 and HR 0,88, 95% CI 0,50-0,98 respectively), serum NT-pro-BNP (HR 1,10, 95% CI 1,05-2,14 and HR 1,14, 95% CI 0,07-4,28, respectively) and chemokine ligand 18 (HR 1,15, 95% CI 1,11-5,75 and HR 1,13, 95% CI 1,09-4,50). A case of successful use of idarucizumab for reversal of dabigatran anticoagulant effect in the patient with severe bleeding from esophageal erosion, nonvalvular AF, HF and COPD was reported. Coagulation was restored within 4 hours, which allowed to stop bleeding conservatively and antishock measures were effective. Conclusion. Anticoagulation therapy in patients with AF and comorbidity of HF and COPD is associated with additional risk of major bleeding, especially gastrointestinal. Possibility to reverse the anticoagulant effect is an important argument when choosing an anticoagulant for these patients.

Aim. To establish the efficacy of 13-valent pneumococcal conjugate vaccine (PCV13) for healthcare workers protection from occupational acquired infection and impact of healthcare staff vaccination on the risk of transmission to patients. Materials and methods. Healthcare personnel (n=157 of whom 105 critical care department staff) and 1770 patients of that critical care department observed. Healthcare workers received PCV13. Infections caused by Str. pneumoniae, respiratory infections regardless of etiology, work absenteeism in healthcare workers during 12 month before and after vaccination assessed. In the same time monitoring of hospital-acquired infections in patients of critical care department performed. Statistical analysis was done using SPSS 24, relationships were assessed by rate ratio, Cox regression, logistic regression and Kaplan-Meier estimator. Results. Healthcare workers' vaccine coverage in critical care department was 97.2%. In healthcare personnel the rate of all pneumococcal infections, asymptomatic carriage of Str. pneumoniae and respiratory pneumococcal infections were decreased after vaccination by 2.1, 2.2 and 2.1 times accordingly. The rate of respiratory infections regardless of etiology was decreased by 30%, р

The study objectives were to determine the significance of deep neck odontogenic infections severity to predict the postoperative morbidity. Observational study was conducted in 2014-2015. A continuous sample of 38 patients who were urgently hospitalized in the Novosibirsk Regional Clinical Hospital with deep neck odontogenic infections and operated on the day of hospitalization was analyzed. SAPS scale rates correlated positively with the duration of the artificial lungs ventilation (ALV). The positive balance of the introduced and withdrawn liquid in the first day of the postoperative period is associated with the ALV duration, which requires accurate dosing of the infusion volumes. The described protocol of perioperative care significantly decreases morbidity in patients with deep neck odontogenic infections.Цель - определить значимость критериев тяжести состояния для прогнозирования качества послеоперационного периода у пациентов с одонтогенными флегмонами дна полости рта. Материал и методы. Проанализирована сплошная выборка 38 пациентов, экстренно госпитализированных в Новосибирскую областную клиническую больницу с одонтогенными флегмонами дна полости рта и прооперированных в день госпитализации. Результаты. Представлены сведения о перио- и послеоперационной терапии пациентов с острыми одонтогенными флегмонами дна полости рта. Установлено соответствие оценки поступавших пациентов по шкале SAPS и длительности искусственной вентиляции легких (ИВЛ). Доказано, что положительный баланс введенной и выведенной жидкости в 1-е сутки послеоперационного периода ассоциирован с длительностью ИВЛ, что требует точного дозирования объемов инфузии. Использование описанного протокола периоперационного ведения больных с подчелюстными флегмонами позволило существенно снизить летальность.
