The analgesic effects of combined bilateral parasternal block and serratus anterior plane block for coronary artery bypass grafting surgery.

Background: Severe pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB).

ERAS in Cardiac Surgery: Wishful Thinking or Reality.

Enhanced recovery after cardiac surgery (ERACS) is a multi-disciplinary approach to improve patient outcomes and reduce complications following cardiac surgery. The aim of ERACS protocol is to optimize pre-operative preparation, reduce surgical trauma, and minimize post-operative stress.The protocol has been shown to improve patient outcomes, including shorter hospital stays, lower rates of complications, and faster return to normal activities.

Epidemiology of surgery associated acute kidney injury (EPIS-AKI): a prospective international observational multi-center clinical study.

Purpose: The incidence, patient features, risk factors and outcomes of surgery-associated postoperative acute kidney injury (PO-AKI) across different countries and health care systems is unclear.

Methods: We conducted an international prospective, observational, multi-center study in 30 countries in patients undergoing major surgery (> 2-h duration and postoperative intensive care unit (ICU) or high dependency unit admission). The primary endpoint was the occurrence of PO-AKI within 72 h of surgery defined by the Kidney Disease: Improving Global Outcomes (KDIGO) criteria.

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.

Preoperative ultrasound-guided bilateral thoracic erector spinae plane block within an enhanced recovery program is associated with decreased intraoperative lactate levels in cardiac surgery.

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.

Preoperative red cell distribution width to lymphocyte ratio as biomarkers for prolonged intensive care unit stay among older patients undergoing cardiac surgery: a retrospective longitudinal study.

In addition, one of the most important ways to prevent the epidemic is to develop population immunity.

A pooled RT-PCR testing strategy for more efficient COVID-19 pandemic management.

Objectives: Reverse transcription polymerase chain reaction (RT-PCR) testing is indispensable in management of the coronavirus disease 2019 (COVID-19) pandemic. However, with the emergence of new variants of severe acute respiratory syndrome coronavirus-2, the cause of COVID-19, the screening capacity of RT-PCR testing is overburdened, and new strategies and capabilities need to be established. One option is pooled RT-PCR testing.

Retrograde autologous priming method reduces plasma free hemoglobin level in aortic surgery.

Background: Although conventional cardiopulmonary bypass (cCPB) is still the most widely used method in open heart surgery, methods such as retrograde autologous priming (RAP) are increasingly popular in terms of limiting hemodilution. Our hypothesis is that the use of the RAP method in aortic surgery may result in a limitation of hemodilution and a decrease in fHb levels. For this purpose, plasma free hemoglobin (fHb) levels were investigated in adult open aortic arch repair with axillary artery cannulation patients using cCPB and rRAP methods.

All in one: Multiple coronary stents, history of stent thrombosis, pancreatic carcinoma, postoperative bleeding and thrombocytosis.

Although the management of a stent patient may appear in the guidelines, some patients may be unique and out of class. In this presentation, the patient had multiple thrombotic risk factors for perioperative myocardial injury. These factors included coronary artery disease with multiple implantations of drug-eluting stent (DES), stent thrombosis history, implantation of a new stent 11months ago and hypercoagulability (due to malignancy and surgical procedure).

Building a patient blood management program in a large-volume tertiary hospital setting: Problems and solutions.

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.

Peri-operative blood transfusion in elective major surgery: incidence, indications and outcome - an observational multicentre study.

Background: Patients' demographic and epidemiological characteristics, local variations in clinicians' knowledge and experience and types of surgery can influence peri-operative transfusion practices. Sharing data on transfusion practices and recipients may improve patients' care and implementation of Patient Blood Management (PBM).

Methods: Thirty adult, ASA I-III patients undergoing elective off-pump coronary surgery were included in the study. According to the presence of essential hypertension preoperatively, patients were divided into two groups.

Can Pre-Operative HbA1c Values in Coronary Surgery be a Predictor of Mortality?

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.
