Introduction: In the perioperative period, regional analgesia techniques may play an increasingly important role in "Enhanced Recovery After Surgery (ERAS)" programs, as they can facilitate recovery. We hypothesized that Erector Spinae Plane (ESP) block could improve regional perfusion, thereby limiting blood lactate increase. Therefore, we aimed to evaluate the effect of ESP block on intraoperative blood lactate levels in patients scheduled for elective on-pump cardiac surgery with ERAS protocol. Methods: A total of 68 adult patients scheduled for on-pump cardiac surgery were included. All patients were randomized to the ESP group and the non-ESP group. Blood lactate analyses were performed at intraoperative five-time points. C-Reactive protein (CRP) values were also measured. Results: Blood lactate values were significantly lower in the ESP group than in the Non-ESP group, at the end of CPB [1.78 (1.23–2.78) mmol L−1 to 2.63 (1.70–3.12) mmol L−1] and during the sternal closure period [1.78 (1.27–2.42) mmol L−1 to 2.40 (2.14–2.80) mmol L−1] (p = 0.039, p = 0.009). In addition, CRP values were significantly lower in the ESP group in the postoperative period [0.048 (0.036–0.105) g L−1 to 0.090 (0.049–0.154) g L−1] (p = 0.035). Conclusions: This study showed that preoperative bilateral single-shot ESP block significantly reduces intraoperative final blood lactate and postoperative CRP values. We consider that these results are related to the attenuation of intraoperative hypoperfusion and the alleviation of surgery-related postoperative inflammation. ERAS programs aim to achieve the rapid recovery of patients, a decrease in inflammation, and high-quality analgesia with less opioid consumption. Therefore, our results also prove that it is easier to reach the primary goals of ERAS programs with the application of ESP block in cardiac surgery. [ABSTRACT FROM AUTHOR]

Background: The perioperative risk factors that cause severe morbidity and prolongation of postoperative hospital stay after cardiac surgery should be determined. Various scores have been used to predict morbidity and mortality. Preoperative blood counts are considered potential biomarkers of inflammation and oxidative stress. Inflammatory and immune imbalances may have a significant impact on postoperative adverse events. The present study aimed to investigate the association and potential predictive properties of red cell distribution width/ lymphocyte ratio (RLR) for major adverse events in adult patients who underwent coronary surgery with cardiopulmonary bypass. Methods: After approval from the ethics committee, pre- and post-operative data of 700 patients were obtained from the electronic database of the hospital, intra- and post-operative anesthesia, and intensive care unit follow-up charts. We performed a stepwise multiple logistic regression analysis to investigate the association of RLR with major adverse events in adult patients who underwent coronary surgery with cardiopulmonary bypass. Results: Among 700 patients, 47 (6.7%) had major adverse events after surgery. Multivariate logistic regression analysis showed that age (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.03–1.12; P < 0.001), mean platelet volume (OR, 1.49; 95% CI, 1.07–2.06; P = 0.017), and RLR (OR, 1.21; 95% CI, 1.02–1.43; P = 0.026) were significantly associated with major adverse events. Conclusions: RLR indicates the balance between inflammatory and immune responses. Therefore, it can be used to predict adverse events following coronary surgery. [ABSTRACT FROM AUTHOR]

Natural fiber reinforced thermoplastic composites are of interest for industries searching for not only bio-based but also recyclable and even biodegradable products. One of the drawbacks of natural fiber reinforced thermoplastic composites is the poor fiber-matrix adhesion due to hydrophilic characteristics of natural fibers in contrast with hydrophobic characteristics of thermoplastic polymers. Considering the difference between hydrophilic/hydrophobic characters of fiber and matrix, various surface modification methods were incorporated to improve the compatibility. In this study, alkaline and atmospheric plasma surface treatments were investigated in terms of their effects on both mechanical performances of flax/polypropylene composites and environmental impacts. When the environmental effects of surface modifications before the composite manufacturing were compared; generated equivalent CO2 emissions were calculated as five times less in the case of atmospheric plasma treatment. Flax/polypropylene composites showed similar or even better mechanical performances when atmospheric plasma treatment was applied rather than alkaline treatment. [ABSTRACT FROM AUTHOR]

Cold agglutinin disease(CAD) is an autoimmune disease that occurs against erythrocyte antigens. It is usually idiopathic, but some infections can also be a trigger. CAD becomes active in the peripheral circulation at lower temperatures more easily when exposed to cold, causing hemolysis or agglutination. In this article, the management of a coronary bypass case with CA formation in intraoperative period is presented. A 46-year-old diabetic and hypertensive male patient had COVID-19 2 months ago. Cardiopulmonary bypass(CPB) was initiated with adequate heparinization, and the patient was cooled to 32°C. It was noticed that there were clots in the cardioplegia delivery line(+1°C). Agglutinations were observed in the autologous blood of the patient whose ACT values were normal. After CPB, the operation was completed without any problems and the patient was discharged on the 5th day with recovery. A diagnosis of CAD was made with the results of peripheral smear and immunologic tests. Determination of antibody concentration and thermal amplitude in the preoperative period in patients with CAD is very important. While preparing such patients for surgery, heating of room, patient, fluids, planning of normothermic CPB, and using warm cardioplegia are required. The relationship between CAD and COVID has started to take place in the literature. The patient we presented had a COVID 2 months ago, cold agglutinin may have been induced by COVID or may have arisen idiopathic. Considering that many people may have had a COVID nowadays, care should be taken especially in the perioperative period of cardiac surgery. [ABSTRACT FROM AUTHOR]

Objective: One of the factors affecting liver functions in open coronary surgery (CABG) of patients with metabolic syndrome (MS) may be the anesthetic drugs used. For this purpose, we investigated the effects of midazolam-based total intravenous anesthesia (TIVA) and sevoflurane-based inhalation anesthesia on liver functions and postoperative complications in patients with MS who wiould undergo open coronary bypass surgery. Method: A total f 76 patients were included in our study. A statistically significant difference was not found between the TIVA (n=38) and SEVO (n=38) groups in terms of gender, age, body mass index (BMI), Euroscore values, presence of preoperative comorbidity, blood product transfusion, postoperative complications, and 30-day mortality rates. (p>0.05). Preoperative and postoperative laboratory parameters, ALT, AST, LDH, and glucose values were comparable between both groups. Results: 76 patients were included in our study. There was a statistically significant difference between the TIVA (n=38) and SEVO (n=38) groups in terms of gender, age, body mass index (BMI), euroscore values, presence of preoperative comorbidity, blood product transfusion, postoperative complications, and 30-day mortality rates. There was no difference (p>0.05). When compared according to preoperative and postoperative laboratory parameters, ALT, AST, LDH, and glucose values were found similar in both groups. Conclusion: In our study, we found that TIVA and SEVO groups are not superior to each other in coronary bypass patients with metabolic syndrome. Studies investigating detailed parameters with more patients will be guiding for this issue. [ABSTRACT FROM AUTHOR]

Pulmonary artery (PA) aneurysm is a very rare disease. Surgical treatment is important in symptomatic patients. Due to its anatomical condition, the rupture of such aneurysms may lead to sudden right ventricular failure or sudden death. The aim of this report is to present the use of balanced general anaesthesia management in a patient who underwent PA aneurysm repair surgery. Surgical repair was planned in a 55-year-old man with chest and back pain as well as haemoptysis. With the help of balanced anaesthesia, stress on the aneurysm wall was prevented by avoiding sudden blood pressure increases. With appropriate ventilation methods, we attempted to avoid an increase in pulmonary vascular resistance, and therefore, the pressure on the aneurysm, as well as an increase in the postoperative right ventricle. With the help of appropriate anaesthesia and ventilation techniques, uncomplicated and successful anaesthetic management was effected in the repair of a PA aneurysm. [ABSTRACT FROM AUTHOR]

Textiles are known to be one of the three basic needs of human beings as from the past to the present day. Consumption of textile products has increased along with the rapid development of fashion and population growth. Recycling with compelling reasons, such as the protection of resources in textile products and processes, the need to reduce waste areas, the cost of waste and the need for cheap raw materials for production, is increasingly prevalent throughout the world. With recycling, significant contributions to the world will be achieved in terms of social, economic and environmental aspects. Many countries have stepped up their work on industrial basis by taking precautions in this regard. Textile in our country has a very important place because it is one of the leading industrial sectors and more than 95% of textile materials can be recycled and evaluated. In this study, a general evaluation of recycling in textiles was made. [ABSTRACT FROM AUTHOR]

Washing processes, detergant agents, washing cycles and temperatures can often cause damage on fabrics. The aim of this work was to determine chemical and physical changes on cotton fabrics with different washing conditions. A Box-Bhenken statistical design was used to evaluate the effect of washing temperature (40 -50-60°C), number of washing (10, 30, 50) and washing agent (only water, base detergent, detergent with bleaching agent) on the average degree of polymerization. The effect of multiple washes on cotton fabrics was evaluated by means of average polymerization degree, tensile strength, whiteness index and scanning electron microscopy. Whiteness index decreased significantly using with base detergent and bleaching agent containing detergent, whereas washing with only water did not affect significantly to whiteness index, with increasing number of washing. However, temperature (p > 0.05) individually were not found statistically significant for whiteness index. As number of washing and temperature increased, tensile strength values decreased. Also, washing agent (p > 0.05) individually were not found statistically significant for tensile strength. When evaluated in terms of average polymerization degree values, after the washings with base detergent and bleaching agent containing detergent, there is a greater decrease in the average polymerization degree relative to the only water washings. While the temperature increased in washing process, the average polymerization degree decreased and the lowest average polymerization degree was obtained at 60 °C and 50 washing cycles SEM images indicate that number of washing and the content of detergent are important parameters in the washing process. The worst image in this study was obtained with 50 washes using detergent containing bleaching agent. Washing processes cause undesirable results on the surface of fabrics. [ABSTRACT FROM AUTHOR]

Objective: One of the most frequently studied parameters in terms of outcome estimation in cardiac surgery is HbA1c. Several studies in literature suggest that high HbA1c value increases mortality and morbidity, but there is no relation between them. The primary aim of the present study is to investigate whether HbA1c value in diabetic patients undergoing coronary bypass graft surgery is an independent predictor for post-operative mortality and morbidity, and our secondary goal was to determine independent risk factors that cause mortality and morbidity in the same patient population. Methods: 380 diabetic patients diagnosed with diabetes who underwent coronary surgery with cardiopulmonary bypass in Mersin State hospital between July 2014 to December 2016 after the approval of the Mersin University Faculty of medicine ethics committee were included in this retrospective, observational, and cross-sectional study. Patient demographic and perioperative information were obtained from the electronic information operating system and from anesthesia-intensive care follow-up forms. The HbA1c threshold was accepted as 7%, which was reported to be more appropriate for evaluating high-risk groups. Results: Three hundred and fifty-four patients with complete access to the data were included in the study. The mean age of the patients was 60.8±9.4 years. 37% of the patients (131 patients) were female. The number of patients with HbA1c=7 was 194 (54,8%) in the entire patient population. In this study, high HbA1c (=7) values in diabetic patients undergoing isolated coronary bypass graft surgery were not found to be independent predictors of post-operative mortality and morbidity. Mortality was seen in 28 patients (7.9%). ejection fraction (EF) was found to be an independent predictor factor for pre-operative factors in logistic regression models constructed according to mortality predictors (OR:0.94; 95% CI: 0.90-0.99; p=0.016). Complications were seen in 50 patients (14.1%). In the models formed from the point of view of the complication predicators, only EF was found to be independent predictor (OR:0.95; 95% CI: 0.92-0.98; p=0.004). It was found that HbA1c was not predictive in all models for mortality and complication (p>0.05). Conclusion: There are reports in the literature that mortality increases 4-fold when HbA1c value is higher than 8.6% in coronary surgery. However, there is a view that HbA1c alone cannot predict mortality in coronary surgery if diabetes associated factors are excluded. In this study, high HbA1c (=7) values in diabetic patients undergoing isolated coronary bypass graft surgery were not found to be independent predictors of post-operative mortality and morbidity. Pre-operative low ejection fraction was found as an independent risk factor for post-operative mortality and morbidity in the general patient population. [ABSTRACT FROM AUTHOR]

For an anesthesiologist, it is important to manage the hemodynamics of patients who develop atrial fibrillation (AF) during the perioperative period. In a patient undergoing Whipple surgery, atrial fibrillation, which is thought to occur with an astonishing intraoperative cause has not been reported in the literature. There are multiple risk factors for the development of new onset AF such as older age, diabetes, hypertension, hypovolemia, electrolyte imbalances, hypoxia, and underlying heart disease, etc. But also, during surgery, direct irritation of diaphragmatic surface of the heart with retractor may trigger AF.

Simultaneous Monitoring of Quantitative EEG and Cerebral Oxygenation in Heart Transplantation Objective: In this article, we discuss intraoperative changes of EEG, SEF, PSI values measured by SedLine® and bilateral cerebral oxymetry (rSO2) values measured by NIRS in heart transplantation, and their interrelationships. Material and Methods: Thirteen adult patients who had undergone heart transplantation were included in our study. Demographic, and clinical data, intraoperative hemodynamic values; cerebral monitorization and mortality data were collected prospectively. Bilateral SEF values, PSI values and bilateral rSO2 values were recorded before (phase 1), and 5 minutes (phase 2), after anaesthesic induction of anesthesia 5 minutes after establishing cardiopulmonary bypass (phase 3), 5 minutes after cross-clamping (phase 4), at 5. minute after weaning from cardiopulmonary bypass (phase 5), and at the end of the operation (phase 6). Results: Mean age of the patients was 32.7±10.8 years. rSO2 and SEF values did not show any significant difference between right and left hemispheres. Preoperative SEF, PSI and rSO2 values declined significantly after induction of anesthesia and remained significantly lower compared with the baseline measurement throughout the operation. Discussion and Conclusion: In this study, cerebral monitoring values decreased significantly after induction due to the impact of anesthesia and remained low throughout the operation as expected. Any critical adverse event which required intervention did not occur. in these cases. Multimodal neuromonitorization can be a lodestar for anaesthetic induction, resternotomies, cannulation, serious arrhythmias, hypotensive attacks due to medications used, embolic events due to intracardiac thrombi and sudden development of dysfunction in the donor heart in these patients with borderline ventricular function.

Long QT syndrome is a congenital disorder that is characterized by a prolongation of the QT interval on electrocardiograms and a propensity to ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest or sudden death. Cardiomyopathy and pulmonary hypertension diseases have additional risks in anaesthesia management. In this study, we emphasize on one lung ventilation, pacemaker-implantable cardioverter-defibrillator and the anaesthesia management process in a patient with long QT syndrome, cardiomyopathy and pulmonary hypertension who underwent thoracic sympathectomy.

This study aims to prioritize individuals in vaccination for the effective use of the COVID-19 vaccine, which has limited supply and does not seem possible to be supplied by all countries at the same time. In the study, multi-criteria decision-making methods (MCDM), which offer practical solutions to decision problems, were used considering the structure of the problem. First, the analytic hierarchy process (AHP) method was used to calculate the weights of the criteria. Then, the ranking of the priorities of the individuals was carried out with the PROMETHEE method. Here, the AHP and PROMETHEE methods are used in an integrated manner. It has been determined that the highest priority individual in vaccination is a healthcare worker with a high potential for transmission. In order of priority, the second individual was identified as workers. In this study, a hierarchical structure was created to prioritize individuals who will be vaccinated against COVID-19 and the problem was solved in two stages. A health policy proposal was made to health managers to use limited vaccine resources by prioritizing individuals effectively. In terms of efficient and effective use of resources during possible pandemic periods, the application process of the study provides an exemplary solution for decision-makers and contributes to the solution of similar decision problems encountered both in the literature and in real life. At the same time, offers solution for disasters that require effective use of limited resources, etc. The implementation process of the study may also be taken into account in exceptional circumstances.

In this manuscript, we describe a significant advantage of the intraoperative near infrared spectroscopic techniques (NIRS) using in a malignant hypertensive patient during kidney transplantation. This patient underwent operation becasue of the presence of a suitable cadaveric kidney. Moreover, although the patient's hypertension was intensively treated by cardiology for a long time, it could not be controlled. Thus, despite severe hypertension, the patient was anaesthetized. Mean arterial pressures of about 70-90 mmHg, which are considered to be normal for most people, could cause cerebral hypoperfusion in such a patient. It is a significant advantage that the lower limit of cerebral autoregulation is quickly assessed by NIRS in the case of a kidney transplant performed under general anaesthesia.

Transient neurologic dysfunction is common after aortic surgery. Major causes of postoperative complications followed by cardiac surgery are due to hypoperfusion states such as selective cerebral perfusion, embolic debris during cardiopulmonary bypass and ulcerated plaque emboli originated from carotid arteries. Neurologic complications prolong periods of intensive care unit and hospital stay, worsens quality of life and unfortunately they are an important cause of morbidity. Anaesthesia during a carotid and aortic surgery constitutes of providing adequate brain perfusion pressure, attenuating cerebral metabolism by anaesthetic agents and monitoring the cerebral metabolic supply and demand relationship during the intraoperative period. We present a monitoring approach with an intraoperative 16-channel electroencephalography and bilateral near infrared spectroscopy during redo aneurysm of the sinus of Valsalva surgery.

We have investigated the effects of ketamine-based and remifentanil-based anesthetic protocol on perioperative serum cystatin-C levels, and creatinine and/or cystatin-C-based eGFR equations in terms of acute kidney injury in coronary artery bypass graft (CABG) surgery. Using a simple randomization method (coin tossing), patients were divided into the two groups and not-blinded to the anesthetist. Remifentanil–midazolam–propofol or ketamine–midazolam–propofol-based anesthetic regimen was chosen. Different eGFR formulas using creatinine (MDRD, CKD-EPI, Cockrauft Gault); cystatin-C (eGFR1, eGFR2) or a combination of creatinine and cystatin-C (eGFR 3) were used to calculate estimated glomerular filtration rates (eGFRs). High-sensitive troponin T was used to determine if ketamine use in coronary surgery contributed to myocardial cell damage. Thirty-seven patients were included in the study (remifentanil group = 19, ketamine Group = 18). Urea, creatinine, cystatin-C levels were comparable between the groups in all the measurement times and also postoperative day 2 samples showed statistically higher results compared to baseline (p < 0.001). Effects of ketamine and remifentanil on renal functions were found similar. Creatinine and cystatin-C-based eGFR equations resulted similar in our study. Reversible stage 1 acute kidney injury (AKI) was observed on postoperative day 2 in seven patients from the remifentanil group and six patients from the ketamine group. Hs-troponin T was found to be higher in postoperative day 1 samples; there were no significant difference between the groups. Our results indicated that patients who have normal renal functions undergoing on-pump coronary bypass surgery, effects of ketamine and remifentanil on renal functions in terms of AKI were found to be similar.

Most milk-applied antioxidant assays in literature are based on the isolation and quantification of individual antioxidative compounds, whereas total antioxidant capacity (TAC) gives a more holistic picture due to cooperative action of antioxidants. Recently, the cupric reducing antioxidant capacity (CUPRAC) method has been modified to measure the antioxidant capacities of thiol-containing proteins, where the classical ammonium acetate buffer – that may otherwise precipitate proteins– was replaced with concentrated urea buffer (able to expose embedded thiol groups of proteins to oxidative attack) adjusted to pH 7.0. Thus, antioxidant capacity of milk was investigated with two competing TAC assays, namely CUPRAC and ABTS (2,2′-azinobis(3-ethylbenzothiazoline-6-sulphonic acid))/persulphate, because only these assays were capable of evaluating protein contribution to the observed TAC value. As milk fat caused turbidity, experiments were carried out with skim milk or defatted milk samples. To determine TAC, modified CUPRAC method was applied to whole milk, separated and redissolved protein fractions, and the remaining liquid phase after necessary operations. Both TAC methods were investigated for their dilution sensitivity and antioxidant power assessment of separate milk fractions such as casein and whey. Proteins like β-lactoglobulin and casein (but not simple thiols) exhibited enhanced CUPRAC reactivity with surfactant (SDS) addition. Addition of milk protein fractions to whole skim milk produced significant ‘negative-biased’ deviations (up to −26% relative standard error) from TAC absorbance additivity in the application of the ABTS method, as opposed to that of the CUPRAC method less affected by chemical deviations from Beer's law thereby producing much smaller deviations from additivity (i.e. the property of additivity is valid when the measured TAC of a mixture is equal to the sum of individual antioxidant capacities of its constituents).
