Objectives: Cytokine release triggered by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) depends on a dysregulated immune response and is associated with high mortality. Extracorporeal cytokine hemoadsorption (HA) can be considered a possible adjuvant therapy. This study aimed to review the outcomes of critically ill patients with COVID-19 treated with HA and analyze possible factors associated with mortality. Methods: Data of patients who received HA for at least one cycle from April 17, 2020, to January 31, 2021, were collected. Clinical and laboratory features were recorded, and mortality was evaluated based on the extracorporeal treatment application time and intensive care units (ICU) admission. Results: Data from 177 patients among 4733 ICU patients were analyzed. Their mean age was 60.9±10.9, and 40 (22.6%) of them were females. About 83% of them were mechanically ventilated, and the overall mortality was 76%. In univariate analysis, the mean age, median acute physiology and chronic health evaluation (APACHE)-II score, respiratory support rate, and duration between ICU admission and first cytokine filter were lower in the survivor group than in the non-survivor group. In binary logistic regression analysis, higher APACHE-II with an odds ratio of 1.06 (95% confidence interval [CI]: 1.005–1.128, p=0.033), invasive mechanical ventilation with an odds ratio of 138.4 (95%CI: 24.2–791.8, p<0.001), and later application of HA with an odds ratio of 1.190 (95%CI: 1.009–1.404, p=0.039) were independently associated with in-hospital mortality. Conclusion: Cytokine HA was applied to a large number of patients at our center. Although this was conducted in a severe population with high mortality, besides invasive mechanical ventilation, late application of the cytokine filter was found as one of the factors independently associated with higher mortality [ABSTRACT FROM AUTHOR]

Introduction: Prolonged weaning is associated with worse clinical outcomes in elderly patients. Beside traditional rapid shallow breathing index (RSBI), diaphragm ultrasound is a promising technique to evaluate the weaning process. We aimed to perform diaphragm ultrasonography for predicting the weaning process and its relation with frailty in the critically ill elderly population., Materials and Methods: We enrolled thirthy-two patients over 65 years of age who were mechanically ventilated for at least 48 hours. Thickness of diaphragm and excursion were evaluated within 48 h of intubation and during spontaneous breathing trial (SBT). Clinical parameters, frailty, diaphragm ultrasound results were compared according to the weaning status., Results: Mean age (standard deviation) was 79.3 ± 7.9 years, and 18 (56.3%) patients were classified as weaning failure. Diaphragmatic excursion during SBT was the only statistically significant parameter associated with weaning failure [2.37 cm (0.67) vs 1.43 cm (0.15), p= 0.0359]. There was no statistically significant difference regarding RSBI between the groups [70.5 (46) vs 127.5 (80), p= 0.09]. Baseline thickness of diaphragm and excursion at SBT were moderately correlated with frailty., Conclusion: Ultrasound can be used to show diaphragm dysfunction in the elderly frail population, and a multifactorial approach to the extubation process may include ultrasound instead of using traditional RSBI alone.

Introduction: Sarcopenia and frailty are critical factors linked with poor clinical outcomes among elderly individuals. This study aims to investigate the association between nutritional assessment tests and frailty with muscle thickness measured by ultrasound and their relationship with weaning among critically ill elderly patients., Materials and Methods: Patients who were over 65 years old and required invasive ventilation were assessed for nutritional status and clinical frailty scale upon admission to the intensive care unit. Additionally, the thickness of their rectus femoris and vastus intermedius muscles were measured by ultrasound within 48 hours of intubation. Correlation analysis was conducted to examine the relationship between screening tests, frailty, and ultrasound results. The association between these parameters and weaning success was also evaluated., Result: Between May and August 2022, 32 consecutive patients were enrolled in the study. The mean age was 79.3 ± 7.9, and 18 (56.3%) of them were female. Median APACHE-II- and first-day SOFA scores were 22.5 (16.2-29.7) and 7 (5-10.75), respectively. There was a moderate negative correlation between the thickness of the rectus femoris and frailty (r= -0.41, p= 0.036), and there was a moderate positive correlation between the rectus femoris and geriatric nutritional risk index (r= 0.45, p= 0.017). Of them, 18 (56.3%) patients were classified as weaning failure in which the mean frailty score was higher (7.6 ± 0.9 vs 6.5 ± 1.7, p= 0.035), sepsis (18 vs 7, p<0.001) and use of vasopressor (17 vs 6, p= 0.004) more common, and in-hospital mortality were higher (18 vs 5, p<0.001)., Conclusions: Bedside ultrasound could be beneficial for detecting nutritional high-risk patients. Frailty was associated with muscle thickness, and it was also associated with weaning failure.

Introduction: Pneumothorax (PTX) and pneumomediastinum (PM) are frequently encountered in patients with Coronavirus disease 2019 (COVID-19) and complicate the management of these patients. In this study, we aimed to evaluate the risk factors that cause PTX/PM complications in patients hospitalized due to COVID-19 pneumonia and the effects of these complications on the course of the disease., Materials and Methods: A total of 503 patients with COVID-19 hospitalized in the COVID-19 ward or intensive care unit (ICU) between September 2020 and December 2020 were included in the study., Result: The median age of patients was 65 (min-max, 21-99) years. Of the patients 299 (59.4%) were male and 204 (40.6%) were female. Of the cases, 26 (5.2%) developed PTX or PM. The patients who developed PTX/PM were older than patients who did not [58.5 (min-max, 21-96) vs 65 years (min-max, 22-99), p= 0.029]. The percentage of PTX/PM development was significantly higher in male patients [F/M= 4/22 (2/7.4%) vs 200/277 (98/92.6%), p= 0.007]. Hypertension as a comorbidity was more commonly seen in the group without PTX/PM (p= 0.007). Ground-glass opacity was the most common tomographic finding in both groups, it was significantly higher in those who did not develop PTX/PM (p<0.001). The length of hospital stay was shorter in patients with PTX/PM (p<0.001), but mortality was higher (p= 0.04)., Conclusions: PTX/PM were relatively more common in COVID-19 patients. These complications may negatively affect the prognosis of the disease.

Successful implementation of a patient blood management program necessitates the collaboration of a strong organization and a multidisciplinary approach. We organized a meeting with broad participation in our center to establish a consensus for implementation of a specific patient blood management program. International and domestic experiences were shared, the importance of coordination and execution of different pillars in patient blood management were discussed, and the problems about the blood transfusion system were also investigated with the proposal for solutions. The data obtained from this meeting are presented to be a guide for similar large-volume tertiary hospitals for integration of a patient blood management protocol., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2020, Turkish Society of Cardiovascular Surgery.)

Background: In this study, we aimed to investigate the effects of poor blood glucose control on the intraoperative cerebral system in patients undergoing coronary artery bypass grafting using various neuromonitors., Methods: Between January 2011 and December 2011, a total of 40 adult patients (31 males, 9 females; mean age 58.8±9.2 years; range, 38 to 78 years) who were scheduled for elective coronary artery bypass grafting were included in the study. The patients were divided into four groups according to hemoglobin A1c levels as follows: Group 1 including non-diabetic controls (n=11); Group 2 including those with a hemoglobin A1c value of <7% (n=10); Group 3 including those with a hemoglobin A1c value of 7 to 10% (n=11); and Group 4 including those with a hemoglobin A1c value of ≥10% (n=8). Cerebral monitoring was performed with near-infrared spectroscopy and transcranial Doppler. Measurement periods were defined as follows: Before anesthesia induction (period 1), 10 min after anesthesia induction (period 2), during cannulation (period 3), 10 min after cardiopulmonary bypass (period 4), at 32°C temperature during cardiopulmonary bypass (period 5), at 36°C temperature during cardiopulmonary bypass (period 6), and at the end of the operation (period 7)., Results: There was a significant difference in the near-infrared spectroscopy values in the cannulation period for both right (p<0.001) and left (p=0.002) sides and the mean transcranial Doppler flow velocity (p=0.002) in Group 4, compared to Group 1. The heart rate was found to be significantly lower in Group 4 in the cannulation period. The near-infrared spectroscopy values and transcranial Doppler blood flow velocity decreased in Group 4 in all measurement periods., Conclusion: The results of our study show that, in patients with severe diabetes undergoing open heart surgery, heart rate decreases in the cannulation period due to possible autonomic neuropathy, and cerebral blood flow and oxygenation decrease. For these patients, particularly in the cannulation period, perfusion of both cerebral and other organs should be closely monitored and necessary interventions should be performed., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2020, Turkish Society of Cardiovascular Surgery.)

Background/aim: Cardiac surgery, especially in the presence of cardiopulmonary bypass (CPB), is associated with an inflammatory reaction that may promote microcirculatory alterations, in addition to the general impact on system hemodynamics. Anemia and transfusion make patients more susceptible to the deleterious effects of CPB. In this study, it was aimed to evaluate the effect of dilutional anemia, which is caused by CPB and can be treated with 1–2 units of red blood cell (RBC) transfusion, on global tissue oxygenation parameters in cardiac surgery patients., Materials and Methods: This prospective observational study comprised 127 patients who had a relatively stable operation period without any major anesthetic or surgical complications (e.g., operation duration >5 h, bleeding or hemodilution requiring more than 1–2 units of RBCs, or unstable hemodynamics, requiring inotropic support of more than 5 μg/kg/min dopamine). Patients were observationally divided into two groups: minimally transfused (Group Tr) and nontransfused (Group NTr). Global tissue oxygenation parameters were evaluated after anesthesia induction (T1) and at the end of the operation (T3) and compared between the groups., Results: Group Tr consisted of patients who had significantly lower preoperative hemoglobin values than Group NTr patients. The dilutional anemia of all Group Tr patients could be corrected with 1 unit of RBCs. The lactate levels at T3, increment rates of lactate, and venoarterial carbon dioxide pressure difference (ΔpCO2) levels [(T3 – T1) : T1] in Group Tr were significantly higher than those in Group NTr., Conclusion: Dilutional anemia as a result of CPB mostly occurs in patients with borderline preoperative hemoglobin concentrations and its correction with RBC transfusion does not normalize the degree of microcirculatory and oxygenation problems, which the patients are already prone to because of the nature of CPB. Preventing dilutional anemia and transfusion, especially in patients with preoperative borderline hemoglobin levels, may therefore reduce the burden of impaired microcirculation-associated organ failure in on-pump cardiac surgery., (This work is licensed under a Creative Commons Attribution 4.0 International License..)

Objective: To evaluate the factors that affects the postperfusion syndrome in cadaveric liver transplantations and the effect of the postperfusion syndrome on discharge from the hospital., Methods: Patients who underwent cadaveric liver transplantations between 2007 and 2013 were scanned retrospectively. Intraoperative anaesthesia records, intensive care unit follow-up forms and discharge reports were examined from patient files. Overall, 43 patients having complete data were included in the study. The postperfusion syndrome is defined as asystoli or a decrease in mean arterial pressure of more than 30%, which occurred in the first 5 min of reperfusion and continued for 1 min. Patients were divided into two groups: those who had the postperfusion syndrome and those who did not., Results: The number of patients who had the postperfusion syndrome was 25 of 43 (58.1%). The MELD score of patients without the postperfusion syndrome was calculated as 16.9±3.2 and that of patients with the postperfusion syndrome was 19.7±3.6. A statistically significant relationship was detected between the postperfusion syndrome occurrence and a high MELD score (p=0.013). The diastolic blood pressure just before reperfusion was statistically lower in the group with the postperfusion syndrome than in the other group (p=0.023, 50±8 vs. 58±11). According to the logistic regression analysis, the MELD score and the decrease in diastolic blood pressure before reperfusion were defined as independent predictive factors., Conclusion: According to the study, the ratio for having the postperfusion syndrome was found to be 58.1%. The independent predictor factors affecting the postperfusion syndrome were detected as the MELD score and the decrease in diastolic blood pressure before reperfusion. The postperfusion syndrome during orthotropic liver transplantation is an important issue for anaesthesiologists. The awareness of the related factors with the postperfusion syndrome may help in the development of various preventive strategies.
