Congenital defects are more common in newborns and children of the first year of life and require surgical correction in the first hours, days of life. Surgical interventions against the background of serious diseases and malformations can lead to catabolic stress, circulatory and respiratory disorders, metabolism, water-electrolyte, protein and acid-base states, which are reflected in the indicators of vital functions. Purpose — to conduct a clinical analysis of indicators of vital functions in newborns and infants with congenital surgical pathology with various types of combined anesthesia. Materials and methods. A retrospective study included 150 newborns and infants with congenital malformations of the surgical profile, depending on the anesthesia (inhalation + regional anesthesia — group І (50 newborns); inhalation + intravenous anesthesia — group ІІ (50 newborns); total intravenous — group III (50 newborns)). The parameters of peripheral and cerebral oximetry, blood pressure, heart rate and respiration were analyzed. Results. The minimum indicator of cerebral oximetry was noted in the left brain hemisphere of children of the ІІ group — 50.57±16.66, which may be an unfavorable prognostic factor in further recovery and influence on the cognitive functions of the child's brain. 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). Conclusions. Among the surveyed groups, the most vulnerable to pathological changes in vital function indicators were children for whom anesthetic support was provided by inhalation anesthesia with sevoran with regional anesthesia. 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 author. Key words: newborns, infants, congenital malformations, combined anesthesia, vital indicators.

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.

Introduction: Congenital malformations (CM) are most common in newborns and infants in the first year of life and require surgical correction in the first hours, days, months of life. Surgical interventions in severely ill babies with malformations can lead to catabolic stress, circulatory and respiratory disorders, metabolism shifts, water-electrolyte, protein, and acid-base status disorders. This study aimed to compare acid-base status in newborns and infants with congenital surgical pathology under different types of combined anesthesia.  Materials and methods: This retrospective study included 150 newborns and infants with CM who required surgery. The patients were divided into three groups based on types of provided anesthesia: inhalation by Sevoran (sevoflurane) and regional anesthesia (group I); inhalation of Sevoran and intravenous anesthesia by Fentanyl (group II); and intravenous combination of Fentanyl and 20% Sodium Oxybutyrate (group III). The analysis included: acid-base status, peripheral oximetry, and the need for an oxygen mixture inhaled by the patient. Results In group I, there was a significant reduction in partial tension of CO2 and increased pH from the pre-surgical status, at the time of induction of anesthesia, during the most painful, traumatic stage, and after surgery compared to group II and III. Peripheral O2 saturation was not critically reduced at all stages of observation except in babies of group I compared to group III at the stage of induction of anesthesia (97.79 ± 2.45 vs. 98.79 ± 1.63, p = 0.0194) and at the most painful period of surgery (96.29 ± 3.47 vs. 98.10 ± 2.47, p = 0.0368). In group I, newborns and infants required higher oxygen concentrations in the inhalation mixture. There was a significant difference in FiO2 between groups I and III during the most painful stage of surgery (0.47 ± 0.29 and 0.33 ± 0.2, p = 0.0071), and immediately after surgery (0.34 ± 0, 19 and 0.26 ± 0.13, p = 0.0246). Conclusion: Among the newborns and infants with CM requiring surgical intervention and combined anesthesia, the most substantial acid-base status changes were observed in the group where anesthesia was provided by Sevoran (sevoflurane) and regional anesthesia (Group I).

Background. In the past decade, near-infrared spectroscopy has gained popularity in neonatal wards. Taking into account modern international experience, the presented work assesses the features of cerebral oximetry in children with surgical congenital malformations under various types of combined anesthesia. The purpose of the study was to assess the state of cerebral oxygenation in newborns and infants with congenital malformations in various types of anesthetic support. Materials and methods. A retrospective study included 150 newborns and infants with surgical congenital malformations, depending on the anesthesia (inhalation + regional anesthesia; inhalation + intravenous and total intravenous anesthesia). The parameters of cerebral oximetry were analyzed in comparison with peripheral saturation, blood pressure, partial pressure of CO2, O2 in the blood, and pH. Results. The minimum index of cerebral oximetry was observed in the left brain hemisphere of children in group I — 50.57 ± 16.66 that may be an unfavorable prognostic factor for further recovery and influence on the cognitive functions of the brain. One hour after the operation, the children of the first group, who received combined anesthesia with sevorane and regional anesthesia, showed the worse indicators of cerebral oxi­metry compared to groups II and III (rSO2 of the right hemisphere in the first group — 56.84 ± 12.27, rSO2 of the left hemisphere in the first group — 57.53 ± 13.32, p = 0.0001; 0.0028), while the differences in this indicator between groups II and III were not found (p = 0.4167; 0.4029). Conclusions. Near-infrared spectroscopy has proven to be a simple, feasible and useful method for monitoring the oxygen saturation of the brain. When choosing a combined anesthesia by inhalation and regional anesthesia in child­ren with congenital malformations for surgical treatment, cerebral oxyge­nation should be more carefully monitored with additional control of peripheral saturation, blood pressure, partial pressure of CO2, O2 in the blood and pH.

In the presented work, we have assessed the features of peripheral oxygenation in children with congenital malformations of the surgical profile under various types of combined anesthesia. The aim of the study. To assess the state of peripheral oxygenation in newborns and infants with congenital malformations with various types of anesthetic support. Materials and research methods. 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 pulse oximetry were analyzed: peripheral oxygenation, heart rate. Additionally, the concentration of oxygen in the respiratory mixture of children was taken into account. Research results. Peripheral saturation did not critically decrease at all stages of observation, with the exception of a 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˂0.05, respectively) and at the most painful moment of the operation (96.29±3.47 versus 98.10±2.47, with p˂0.05). At the painful moment of the operation, it was in children of group I that a drop in heart rate was noted compared to group III (127.98±13.77 and 136.10±15.37, respectively, with p˂0.05) and group II (134.02±18.43, at p>0.05) against the background of a decrease in SpO2. Newborns and group I infants required higher oxygen concentrations in the breathing mixture. A significant difference in the indicator is noted between groups I and III at the traumatic stage – 0.47±0.29 and 0.33±0.2, with p˂0.05, respectively, and immediately after the operation – 0.34±0,19 and 0.26±0.13, with p˂0.05, respectively. Conclusions. The expediency and effectiveness of pulse oximetry for children with congenital malformations at all stages of anesthetic support during surgical treatment was confirmed. The risk group for the formation of oxygen deficiency in organs and tissues, the occurrence of pain during the operation were newborns and infants, for whom combined anesthesia was chosen in the form of an inhalation method and regional anesthesia. In the case of the appointment of this type of anesthetic support, it is necessary to more closely monitor the indicators and promptly correct the deterioration of the child's condition

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.

The Impact

General anesthesia for a surgical correction of congenital malformations in children is accompanied, in particular, by the disorders of systemic hemodynamics. In order to assess the impact of different types of combined anesthesia on the state of systemic hemodynamics in surgical correction of congenital malformations, a retrospective study of the treatment of 150 newborns and infants was conducted. These were children with various congenital malformations, but the most common were intestinal obstruction and abdominal tumors. Three groups of patients were formed depending on the type of combined anesthesia during surgical correction of abnormalities: I − inhalation (sevorane) + regional anesthesia; II − inhalation (sevorane) + intravenous anesthesia (fentanyl); III − total intravenous anesthesia with two drugs: analgesic (fentanyl) and drug sleep on the background of intravenous injection of hypnotics (20 % sodium oxybutyrate). There were preformed the surgeries: thoracic, urological, abdominal. The study was retrospectively evaluated in five stages. The analysis of systemic hemodynamics showed a tendency to reduce diastolic blood pressure in children treated with anesthesia with two intravenous drugs (hypnotic and fentanyl), during all observation stages and a significant decrease in this index at the most painful and traumatic period. At the time of induction of anesthesia in children there was a decrease in heart rate. According to the research results, it is concluded that when using the pre−hypnotics as part of combined anesthesia in children with congenital malformations during surgery there is a risk of complications from central hemodynamics in the form of vasodilation, which leads to a drop in blood pressure and increases compensatively the heart contractions. Key words: infants, congenital malformations, anesthesia, hemodynamics.

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.

Background To fulfill the increasing demand of service quality improvement in recent years, it is imperative to develop a proper instrument to evaluate patient satisfaction with perioperative anesthetic care for many institutes in Taiwan. Methods We used a six-factor 32-item pilot questionnaire developed in our previous study as our starting point in this study. Exploratory factor analysis of the pilot questionnaire for factor structure generation was performed in general anesthesia patients (group 1, n = 320) and resulted in the generation of the Patient Satisfaction with Perioperative Anesthetic Care questionnaire (PSPACq). Confirmatory factor analysis of the PSPACq in general anesthesia (group 2, n = 565) and regional anesthesia (group 3, n = 225) patients was performed for validation and cross-validation of the PSPACq model, respectively. The confounding variables and the patient loyalty effects on PSPACq scores were analyzed to evaluate the nomological validity of the PSPACq. Result Exploratory factor analysis of the pilot questionnaire in group 1 resulted in the development of the PSPACq (a seven-factor 30-item model). The standardized coefficients and indexes for the assessment of fit of the PSPACq model in group 2 (validation) and group 3 (cross-validation) patients revealed a well-fitting model. The results of the loyalty scores and confounding variables support the nomological validity of the PSPACq. Conclusions A valid and reliable questionnaire (PSPACq) with Taiwanese culture characteristics was developed and is suitable for testing of patient satisfaction with perioperative anesthesia care for patients receiving general or regional anesthesia for their surgery.
