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.

Non-interventional Feasibility Assessment for Fast-Track Cardiac Anesthesia.

Background The introduction of fast-track extubation procedures following cardiac surgery has significantly shortened hospitalization duration in intensive care units (ICUs). Early extubation is the most crucial step in getting out of the ICU early and providing ideal patient circulation. In times of crisis such as pandemics, it is vital to provide rapid flow through the hospital to prevent the postponement or inability to operate on patients awaiting surgery.

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.

Anesthesia induction regimens may affect QT interval in cardiac surgery patients: A randomized-controlled trial.

Background: The aim of this study was to investigate the effects on QT interval of the propofol-ketamine combination and the midazolam-fentanyl combination in anesthesia induction for cardiac surgery.

Methods: Between September 2020 and June 2021, a total of 9 5 c ardiac s urgery p atients ( 80 m ales, 1 5 f emales; mean age: 57±9.1 years; range, 26 to 76 years) were included.

Management of renin-angiotensin-aldosterone inhibitors and other antihypertensives and their clinical effects on pre-anesthesia blood pressure.

Background: Blood pressure fluctuations appear more significant in patients with poorly controlled hypertension and are known to be associated with adverse perioperative morbidity. In the present study, we aimed to determine the effects of antihypertensive drug treatment strategies on preanesthetic operating room blood pressure measurements.

Methods: A total of 717 patients participated in our study; 383 patients who were normotensive based on baseline measurements and not under antihypertensive therapy were excluded from the analysis.

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).

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.

Diagnosed in operating room with hypertension: a widespread but unseen affliction.

Objective: The present study aims to describe a widely held misconception in the literature concerning preoperative hypertension diagnosis. The blood pressure elevation occurring in the operative room is seen commonly even in subjects considered hitherto fully normotensive. As these patients have a condition which - similar to White Coat Hypertension (WCH) - indicates the presence of hypertension, and thus necessitates more frequent intraoperative checks.

Anaesthesia Management in Idiopathic Pulmonary Artery Aneurysm Surgery.

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.

Heparin dose calculated according to lean body weight during on-pump heart surgery.

Background: The aim of this study is to compare heparin dose regimen calculated based on the lean body weight with traditional heparin regimen in terms of ensuring adequate anticoagulation and complications associated with perioperative bleeding.

Methods: This prospective, single-blind, randomized study included a total of 100 adult patients (42 males, 58 females; mean age 52.7 years; range, 22 to 84 years) undergoing elective valve surgery with cardiopulmonary bypass between June 2016 and January 2017.

Quick Evaluation of Cerebral Autoregulation Limits with Near Infrared Spectroscopic Techniques in the Intraoperative Period.

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.
