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

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).

In the literature there appears to be variability in reported levels of certain hormones during haemorrhage, specifically adrenocorticotrophic hormone (ACTH) and β-endorphin. It is possible that this variability may be due to the choice of anaesthetic. Therefore, the effect of 3 common research-only anaesthetic agents (alphaxalone–alphadolone, propofol, and pentobarbitone) on ACTH and β-endorphin levels during haemorrhage was assessed in pigs. Animals were divided into 3 groups: group I received alphaxalone–alphadolone (n = 5), group II received propofol (n = 6), and group III received pentobarbitone (n = 6). Pigs were subjected to a continuous fixed-volume haemorrhage under one of the above anaesthetics while being mechanically ventilated. ACTH and β-endorphin levels increased significantly during haemorrhage under propofol and pentobarbitone anaesthesia but not with alphaxalone–alphadolone. For ACTH there was no significant difference between the groups, whereas for β-endorphin there was a significant difference between the propofol- and pentobarbitone-anaesthetized pigs. The increase in heart rate during haemorrhage was significantly different between the alphaxalone–alphadolone and propofol as well as between the propofol and pentobarbitone groups. The drop in blood pressure was only significantly different between the alphaxalone–alphadolone- and propofol-anaesthetized pigs. These results indicate that the choice of anaesthetic agent can affect the hormone response to haemorrhage and may account for the variable hormone levels reported in the published literature to date.

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.

Reducing the burden of pain via greenspace exposure is a rising research topic. However, insufficient evidence has been found in relation to the environmental effect itself. Residential greenspace, as a convenient but limited natural environment for urban dwellers, has benefits and services yet to be discovered. Therefore, the current study recruited 24 young adults to evaluate the effects of physical visit to, or image viewing of, residential greenspace on pain perception and related psychophysiological outcomes, via simulated pain. Pain threshold and tolerance were recorded via the level of pain stimuli, and pain intensity was evaluated using the Visual Analog Scale (VAS). The state scale of the State–Trait Anxiety Inventory (STAI-S) and two adjective pairs were employed to measure the state anxiety and subjective stress, respectively. Meanwhile, heart rate (HR), heart rate variability (HRV), and blood pressure (BP) were measured to investigate physiological responses. Besides, Scenic Beauty Estimation (SBE) was also employed to assess participants’ preference regarding the experimental environments. The results revealed that visiting the greenspace significantly increased the pain threshold and tolerance, while no significant effect was observed for image viewing. On the other hand, no significant difference was observed in pain-related psychophysiological indices between the experimental settings, but significantly negative associations were found between the scores of SBE and subjective stress and state anxiety. In conclusion, the current study brings experimental evidence of improving pain experience via residential greenspace exposure, while the related psychophysiological benefits require further investigation.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

Objectives To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. Methods The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. Results Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III ( P = .4). The most common reason for revision surgery was stenosis of the neo-ostium ( n = 8), followed by granulation tissue formation ( n = 5) and synechia formation ( n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation ( P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates ( P = .79 and P = .76, respectively). Conclusion The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

Background: Bupivacaine with opioid is commonly used for labour epidural analgesia. Ropivacaine is considered as an alternative to bupivacaine due to its lower cardiovascular complications. However, there is a controversy regarding the efficacy of these drugs as some studies suggest equivalent action, whereas others report that ropivacaine produces less motor blockade. The study aimed to compare the effect of ropivacaine-fentanyl and bupivacaine-fentanyl for labour analgesia. Materials and Methods: The prospective randomized study was performed on 60 parturients, divided into two groups of 30 subjects each. Group I received 10ml of bupivacaine 0.1% + fentanyl 2µg/ml and Group II received 10ml of ropivacaine 0.1% + fentanyl 2µg/ml by epidural catheter. Pre-anaesthetic evaluation was performed on all the participants and all were administered metoclopramide 0.25mg/kg and ondansetron 0.08-0.1mg/kg intravenously as premedication. The baseline and post anaesthesia systolic, diastolic blood pressure, heart rate, VAS score, degree of motor block, sedation and APGAR score of the baby were recorded. The data were tabulated and statistically analyzed. Results: When compared, there was no significant difference in systolic/diastolic blood pressure in two groups except at 360 min where diastolic pressure was low in group II. Significantly higher heart rate at 30 min (P=0.0003), 120 min (0.006), and 300 min (P=0.001) was observed in group I subjects. VAS score was significantly less at 180 min (P=0.019) and 300 min (P=0.019) in group II. Adverse effects such as fetal bradycardia, nausea/vomiting and hypotension observed were clinically insignificance when compared in two groups. Conclusion: Bupivacaine and ropivacaine produce an equal degree of analgesia and hemodynamic stability in 0.1% of concentration when added with 2µg/ml fentanyl . However, heart rate was well maintained with lower VAS scores in group II receiving ropivacaine. No significant difference in the side effects between the two groups. Hence, Ropivacaine can be used as a safe alternative to bupivacaine for labour epidural analgesia.
