In pediatric anesthesiology in surgical interventions various methods of combined anesthesia with a combination of inhalation, regional, and intravenous anesthesia are used. The provision of high-quality anesthetic support in newborns and infants during surgical treatment of congenital defects is complicated by risk factors, concomitant diseases and different pathology conditions. The study of risk factors and their influence on the functional indices of the child's vital activity in prescribing anesthesia at all stages of the surgical intervention will help prevent complications and deaths in children. Aim – to сonduct a comparative assessment of various types of anesthesia for surgical correction of congenital defects in children and create a predictive model of the association of risk factors and deaths in the selected methods of anesthetic support. The retrospective study included 150 newborns and infants with congenital defects of the surgical profile depending on anesthesia (inhalation + regional anesthesia; inhalation + intravenous anesthesia and total intravenous). After identifying and evaluating prognostic variables by simple logistic regression with calculating the odds ratio, stepwise multiple logistic regression analysis was performed and a predictive model of the association of risk factors and deaths with various types of anesthetic management was created. In thoracic operations a combined anesthesia with sevoran and fentanyl was most often used – 20.4%. In abdominal operations, in total anesthetic support with sevoran and regional anesthesia was used– 69.4%, while in urological operations combined total intravenous anesthesia with 2 drugs – 18.4% ranked first. No significant diffe­ren­ces were found between the types of anesthesia in various surgical interventions for congenital pathologies, between the types of surgery and deaths (p = 0.863). To prevent fatalities in various types of surgical intervention and options for anesthetic support of newborns and infants with congenital defects, it is advisable to more closely monitor the cerebral and peripheral oximetry indicators at all stages of treatment and timely correct the impaired condition of the child.

Introduction. Various methods of combined anesthesia are used with a combination of inhalation, regional, intravenous anesthesia during surgical interventions in pediatric anesthesiology. It is important to carry out a differentiated approach to the appointment of anesthesia in children at all stages of surgical intervention to prevent complications and deaths in children. Aim. To analyze various types of anesthetic support for newborns and infants with congenital malformations during thoracic, urological and abdominal types of surgical treatment and determine the safest combination of anesthesia. Materials and methods. The retrospective study included newborns with congenital malformations of the surgical profile, as well as infants who received and continued stepwise surgical treatment for congenital malformations, depending on the chosen combined anesthetic accompaniment (inhalation + regional anesthesia; inhalation + intravenous anesthesia and total intravenous one). After identification and assessment of 41 prognostic variables by simple logistic regression with the calculation of the odds ratio, stepwise multiple logistic regression analysis was performed to identify significant factors associated with death. Results. It has been proven that there is no relationship between the age of children, the type of surgical intervention in newborns and infants with congenital malformations with various options for anesthesiological support and deaths. It can be argued that the combination anesthesia options selected for analysis are safe. Conclusions. To prevent the chances of fatalities in various types of surgical interventions and options for anesthetic support of newborns and infants with congenital malformations, it is advisable to monitor blood pressure (especially diastolic), cerebral, peripheral oximetry at all stages of treatment more closely and correct the impaired condition of a child in time.

Annotation. In newborns and infants, surgical interventions against the background of severe concomitant and background perinatal pathologies and malformations lead to catabolic stress, circulatory and respiratory disorders, which are reflected in the indicators of vital functions. Given the high risk of severe complications of organ function in the perioperative and postoperative periods, it is advisable to continuously monitor key clinical parameters. Aim of the study – to establish the absolute values of indicators of vital functions in newborns and infants with congenital surgical pathology with various types of combined anesthesia and compare them with clinical data. A retrospective study included 150 newborns and infants with congenital malformations of the surgical profile, depending on the anesthesia (inhalation + regional anesthesia; inhalation + intravenous anesthesia and total intravenous). The parameters of peripheral oximetry, blood pressure, heart rate and respiration were analyzed. It was found that peripheral saturation did not critically decrease at all stages of observation. With the exception of the resulting decrease in the indicator in children of group I compared with group III at the stage of induction into anesthesia (97.79±2.45 versus 98.79±1.63, at p=0.0194, respectively) and at the most painful moment of surgical intervention (96.29±3.47 versus 98.10±2.47, with p=0.0368). In children who received combined intravenous anesthesia with two drugs, there was an increase in mean arterial pressure from the beginning of surgical treatment to the child's recovery after surgery (49.49±10.71, 56.18±8.05, respectively, at p˂0.01). Thus, among the surveyed groups, the most vulnerable were children for whom anesthesia was provided by Sevoflurane inhalation with regional anesthesia. The performed correlation analysis established the effect of anesthesia on the general hemodynamics in children during all stages of observation.

Background: Multidirectional shoulder instability (MDI) refractory to rehabilitation can be treated with arthroscopic capsulolabral reconstruction with suture anchors. No studies have reported on outcomes or examined the risk factors that may contribute to poor outcomes in adolescent athletes. Hypothesis/Purpose: To identify risk factors for surgical failure by comparing anatomic, clinical, and demographic variables in adolescents who underwent surgical intervention for MDI. Methods: All patients undergoing arthroscopic shoulder surgery at one institution between January 2009 and April 2017 were reviewed. Patients >20 years old at presentation were excluded. Multidirectional instability was defined by positive drive-through sign on arthroscopy plus positive sulcus sign and/or multidirectional laxity on anterior and posterior drawer testing while under anesthesia. Two-year minimum follow-up was required, but those whose treatment failed earlier were included for reporting purposes. Demographics and intraoperative findings were recorded, as were Single Assessment Numeric Evaluation (SANE) scoring, Pediatric and Adolescent Shoulder Survey (PASS), and the short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) results. Results: Eighty adolescents (88 shoulders) were identified for having undergone surgical treatment of MDI. Of these 80 patients, 42 (50 shoulders; 31 female, 19 male) were available at a minimum of 2-year follow-up. Mean follow-up was 6.3 years (range, 2.8-10.2 years). Thirteen (26.0%) shoulders experienced surgical failure defined by recurrence of subluxation and instability, all of which underwent re-operation. Time to re-operation occurred at a mean of 1.9 years (range, 0.8-3.2). Our cohort had an overall survivorship of 96% at 1 year after surgery and 76% at 3 years. None of the anatomic, clinical, or demographic variables tested, or the presence of generalized ligamentous laxity, were correlated with subjective outcomes or re-operation. Number of anchors used was not different between those that failed and those that did not fail. Patients reported a mean SANE score of 83.3, PASS score of 85.0, and QuickDASH score of 6.8. Return to prior level of sport (RTS) occurred in 56% of patients. Conclusion: Multidirectional shoulder instability is a complex disorder that can be challenging to treat. Adolescent MDI that is refractory to non-surgical management appears to have long-term outcomes after surgical intervention that are comparable to adolescent patients with unidirectional instability. In patients who do experience failure of capsulorraphy, we show that failure will most likely occur within 3 years of the index surgical treatment. [Table: see text][Figure: see text]

Background. Lymph node status of clinical T1 (diameter≤3 cm) lung cancer largely affects the treatment strategies in the clinic. In order to assess lymph node status before operation, we aim to develop a noninvasive predictive model using preoperative clinical information. Methods. We retrospectively reviewed 924 patients (development group) and 380 patients (validation group) of clinical T1 lung cancer. Univariate analysis followed by polytomous logistic regression was performed to estimate different risk factors of lymph node metastasis between N1 and N2 diseases. A predictive model of N2 metastasis was established with dichotomous logistic regression, externally validated and compared with previous models. Results. Consolidation size and clinical N stage based on CT were two common independent risk factors for both N1 and N2 metastases, with different odds ratios. For N2 metastasis, we identified five independent predictors by dichotomous logistic regression: peripheral location, larger consolidation size, lymph node enlargement on CT, no smoking history, and higher levels of serum CEA. The model showed good calibration and discrimination ability in the development data, with the reasonable Hosmer-Lemeshow test (p=0.839) and the area under the ROC being 0.931 (95% CI: 0.906-0.955). When externally validated, the model showed a great negative predictive value of 97.6% and the AUC of our model was better than other models. Conclusion. In this study, we analyzed risk factors for both N1 and N2 metastases and built a predictive model to evaluate possibilities of N2 metastasis of clinical T1 lung cancers before the surgery. Our model will help to select patients with low probability of N2 metastasis and assist in clinical decision to further management.

Purpose: Identification of risk factors that influence the outcome of the patient, their ranking on the contribution to the outcome of treatment, as well as determining the possibility of their additional diagnostic evaluation and correction in the deviation at the preoperative preparation stage with the subsequent construction of a prognostic model. Material and methods: The study included patients who received treatment in the surgical department in A. I. Burnasyan Federal Medical Biophysical Center from January 2009 to July 2017, including workers of nuclear facilities that are exposed to ionizing radiation in professional conditions. The study was conducted in 112 patients, 42 of whom (37.5 %) were men and 70 (62.5 %) women aged 25 to 85 years (59.6 ± 13.2). Among the persons included in the study, 25 men and 26 women were exposed to long-term exposure to ionizing radiation from external sources under production conditions during labor activity within the limits of annual maximum permissible doses, averaged 124.6 ± 10.7 mSv. The work experience under conditions of exposure to ionizing radiation ranged from 5 to 35 years, an average of 24 years. The mean age was 59.1 ± 13.4 years. At the end of hospitalization after surgical treatment, 51 patients were discharged (45.5 %), and 61 (54.5 %) died. In all patients, the parameters of the functioning of various organs and systems were collected, including taking into account the anamnestic data of oncological patients, with differentiation in the final outcome of surgical treatment. To determine the leading risk factors for the lethal outcome of the oncosurgical patient, the Fisher criterion χ2 was used. Based on the leading risk factors for constructing mathematical models, the logistic regression equation was used. The mathematical models were analyzed by researching the area under the ROC curves. Results: Using the Fisher criterion χ2, factors were determined by which the groups of survivors and died patients differ: patient age, body mass index, history of heart rhythm disorders, fraction of cardiac output, Hb level in the blood, presence of protein in urine, INR indicator in coagulograms. Based on the identified factors, twelve mathematical models were constructed using the binary logistic regression method, allowing patients to be divided into groups with the outcomes of hospitalization died / survived after surgery. A mathematical model with the best discriminating ability was chosen. Based on the prognostic model, a decision rule was designed that allows to rank patients into three groups: green (patients with a minimal risk of death), yellow (patients who need preoperative correction), red (patients with the maximum risk of death, decision about surgery is necessary to be solved on a consultation).

Uncorrected Visual Acuity

Patients, who need cataract surgical treatment, often fail to achieve a high uncorrected visual acuity after surgery due to the concomitant astigmatism involved. Currently, surgeons are increasingly performing combined surgical interventions, including relaxing limbal keratotomic incisions (manual keratotomy) or femtoarcuatous keratotomy, as well as implanting toric intraocular lenses. In recent years, additional toric intraocular lenses have been available. Purpose: to analyze our own clinical experience of implanting an additional toric intraocular lens to correct corneal astigmatism in three clinical cases. The article presents our clinical experience of successful correction of residual corneal astigmatism after previous cataract phacoemulsification with the implantation of a monofocal toric intraocular lens in three patients patients aged 70, 61 and 54 years. In all cases, an additional toric intraocular lens Add-on Torica-sPB pre-filled in the cartridge with a good refractive effect was implanted. The uncorrected visual acuity was 1.0 in all the investigated cases at the follow-upo period of 6 months after the surgical intervention. Calculation of the toric intraocular lens optical power was performed using an online calculator. A feature of surgical intervention was the repositioning of the additional toric intraocular lens into the ciliary sulcus. Changes in the data of keratotopography before and after surgery were absent. In none of the investigated cases, intra- and postoperative complications and dislocation of the implanted additional toric intraocular lens were determined. Based on these cases, high predictability, efficacy and safety of implantation of an additional toric intraocular lens are shown, in the case of residual middle-grade corneal astigmatism after the initial cataract phacoemulsification with the toric intraocular lens implantation. This approach can be successfully used in patients during one-stage surgical treatment of cataract and associated high-grade corneal astigmatism, expanding existing protocols for the treatment of this group of patients.

To optimize the anatomical and functional surgical treatment results in patients with early (I-II) stages of juvenile femoral head epiphysiolysis both pre- and postoperative data of clinical, x-ray and magnetic-resonance examinations were analyzed for 120 patients aged 11 - 15 years. Maximum follow up period after surgical interventions, i.e. femoral head epiphysiodesis (n=60) and femoral head epiphysis fixation (n=60) made up 23 and 3 years, respectively. It was shown that surgical intervention for the fixation of femoral head epiphysis ensured reliable stability of the epiphysis preventing the latter from displacement development and progression, and did not exert significant influence upon either femoral neck and head endochondral growth or the length of the upper extremity.

Abstract Background: Percutaneous nephrolithotomy (PCNL) is a primary treatment method for renal stones, but infection is a very common postoperative complication. Systemic inflammatory response syndrome (SIRS) is a stage of the infection process and a very important early clinical manifestation of sepsis, so identifying the risk factors associated with SIRS after PCNL is important for ensuring patient safety and preventing sepsis.Objective: To analyze the risk factors for SIRS after PCNL, identify the predictive factors, and perform risk factor analysis.Methodology: Between September 2016 and September 2017, 352 patients who were diagnosed with renal stones and treated with PCNL were included in this study. The patients were divided into two groups according to whether SIRS occurred. Univariate analysis was performed on the related risk factors, including patient age; gender; body mass index; urine culture; number, types and quantity of rental stones; diabetes; blood glucose; complications; hospital stay; residual stones; and Guy’s degree. Then, logistic regression was used to perform multivariate analysis and establish a predictive model.Results: A total of 352 patients with renal stones were treated with PCNL, and 106 patients (30.1%) developed SIRS after surgery. Operative time, preoperative fever and diabetes were found to be risk factors, and the logistic regression results indicated that diabetes (OR=2.049, 95%CI 1.008~4.166) and operative time (OR=1.011, 95%CI 1.003~1.019) could be entered into the regression equation. Therefore, the predictive regression model was P=1/[1+e-(-2.097+0.712 diabetes + 0.012 operative time)].Conclusion: Diabetes and operative time are independent risk factors for SIRS after PCNL, so the probability of SIRS after PCNL can be determined according to these two indicators.

High-quality anesthetic support during surgical correction of congenital malformations of internal organs and the postoperative period in newborns and infants is complicated by concomitant diseases, significantly affects the processes of metabolism, gas exchange, homeostasis, cerebral, peripheral hemodynamics, etc. before, during and after the surgical intervention. Purpose — to identify the leading risk factors associated with death in various types of anesthetic support for newborns and infants during surgical correction of congenital malformations. Materials and methods. The retrospective study included newborns with congenital malformations of the surgical profile, as well as infants who received and continued stepwise surgical treatment for congenital malformations, depending on the chosen combined anesthetic accompaniment (inhalation + regional anesthesia and inhalation + intravenous anesthesia). The study was carried out in the following stages: 1) to conduct surgical treatment and anesthetic support, 2) introduction of the child into anesthesia, 3) the traumatic stage of the operation, 4) within 1 hour after the operation, 5) 24 hours after the operation. Risk factors were determined by simple logistic regression with the calculation of the odds ratio, 95% confidence interval (95% CI). Results. Among the functional indicators of the vital functions of the body of children with congenital disorders before, during, immediately and 24 hours after surgery against the background of combined anesthesia, with a simple logistic regression analysis, the chance of a fatal case increases with deviations from the norm of peripheral saturation — at all stages of surgical support (7.8–15.0 times); cerebral oxygenation of the child — at the moments of induction into anesthesia and in the postoperative period (10.8 at the stage 2, 72.0 times at the stage 4); increased diastolic blood pressure at the stage of induction of the child into anesthesia (1.6 times). Conclusions. To prevent the chances of death under various types of anesthesia for children with congenital malformations during surgical treatment, it is advisable to more closely monitor blood pressure, cerebral, peripheral oximetry and promptly correct the impaired condition of the child. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: newborns, infants, congenital malformations, anesthesia, risk factors.
