A new hematologic predictor of major adverse events after cardiac surgery: red cell distribution width to lymphocyte ratio.

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.

Ultrasound-guided erector spinae plane block in coronary artery bypass surgery: the role of local anesthetic volume-a prospective, randomized study.

Background: Erector spinae plane block has been shown to help with pain management in different regions and many areas with different indications. However, the effectiveness of this block in cardiac surgery has been shown in the literature, the optimal volume remains unclear. The aim of this study is to determine the analgesic efficacy of two different volumes of local anesthetic injection used in ultrasound-guided bilateral-thoracic erector spinae plane block in patients undergoing coronary artery bypass graft.

Effects of intraoperative fluid therapy on intensive care process, morbidity, and mortality after lung transplantation.

Background: This study aims to evaluate the effect of intraoperative fluid therapy on intensive care process and first 90-day morbidity and mortality in patients undergoing lung transplantation.

Methods: Between March 2013 and December 2020, a total of 77 patients (64 males, 13 females; mean age: 47.6±13.

Everolimus Use in Lung Transplant Recipients.

Background: Most lung transplantation centers prefer triple immunosuppressive therapy with tacrolimus, mycophenolate mofetil, and corticosteroids. However, to prevent complications and comorbidities caused by tacrolimus, replacing the drug with everolimus has been considered.

Methods: This is a retrospective observational study investigating everolimus switch for different reasons.

Delirium Development After Lung Transplantation: An Intraoperative Assessment.

Background: This study aimed to evaluate the relationship between intraoperative hemodynamic and laboratory parameters with postoperative delirium development after lung transplantation.

Methods: A total of 77 patients who underwent lung transplantation in a single center were included in the study. Demographic and clinical data recorded at critical intraoperative stages (after induction [T1], after bilateral lungs are dissected [T2], while the patient is ventilated for 1 lung [T3], while the unilateral transplanted lung is ventilated [T4], while bilateral transplanted lungs are ventilated [T5], and after the thorax is closed [T6]), postoperative complications, mechanical ventilation duration, intensive care, and hospitalization durations and mortality rates were recorded.

Dynamic Thiol-Disulfide Homeostasis as a Marker for Oxidative Stress in Lung Transplant Candidates.

Objectives: Oxidative stress developing due to oxidant/antioxidant imbalance plays a crucial role in the etiopathogenesis of chronic progressive lung diseases.The condition is typically more severe in lung transplant candidates with end-stage lung disease. Here, we investigated dynamic thiol-disulfide homeostasis as a marker for oxidative stress in lung transplant candidates.

COVID-19 After Vaccination in Lung Transplant Recipients: Real-Life Data.

Objectives: The effectiveness of COVID-19 vaccines in lung transplant recipients is unclear. We retrospectively analyzed lung transplant recipients vaccinated with an inactivated virus vaccine (CoronaVac) and the mRNA vaccine BNT162b2 used against the SARS-CoV-2 virus in Turkey and shared their effects on COVID-19.

Materials And Methods: Demographic data of lung transplant recipients followed up for >3 months were collected, and vaccination dates and status against the SARS-CoV-2 virus were recorded.

COVID-19 in a Lung Transplant Patient: Rapid Progressive Chronic Lung Allograft Dysfunction.

The pandemic of SARS-CoV-2, known as COVID-19, has continued to show its effect all over the world. The clinical course of the disease in solid-organ transplant recipients is a matter of concern. Lung transplant recipients also demonstrate special features because the graft encounters the COVID-19 pathogen directly as a result of inhalation, and the lungs are the most important organs affected by the disease.

Effects of upper limb ischemia-reperfusion on regional oxidative stress during aortic surgery with moderate hypothermia.

Introduction: This study aims to evaluate the effect of acute, iatrogenic right arm ischemia and reperfusion (I/R) due to right axillary cannulation on regional oxidative stress using tissue perfusion markers such as central venous oxygen saturation, lactate, the difference between central venous and arterial CO pressure, near-infrared spectroscopy (NIRS) measurements, and biomarkers like sialic acid, malondialdehyde, advanced oxidative protein products in aortic surgery with moderate hypothermia.

Methods: Adult patients undergoing ascending aorta repair with antegrade cerebral perfusion via the axillary artery participated. Blood samples were collected from the internal jugular vein, right arm cubital vein, and left arm cubital vein, and analysis was performed at intraoperative time points.
