Does uncontrolled diabetes mellitus affect cerebral hemodynamics in heart 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.

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.

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.

Hematological predictors and clinical outcomes in cardiac surgery.

Purpose: The present study was to investigate if five values that are part of the hemogram analysis routinely checked before heart surgeries can be used as a high-quality, quick, low-cost, and easy-to-use outcome predictor.

Methods: This investigation was a retrospective, observational, cross-sectional study. Univariate and multivariate logistic regression was used to identify independent predictors for combined adverse events.

A comparison of the effects of ketamine and remifentanil on renal functions in coronary artery bypass graft 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.

Evaluation of positive inotropic drug effects on thyroid hormone levels after open heart surgery.

Objective: The aim of this study was to examine the effects of positive inotropic drugs, including adrenaline, dopamine, and dobutamine on thyroid hormone levels following open heart surgery.

Methods: We analyzed free thyroid hormones (FT3 and FT4) and thyroid-stimulating hormones (TSH) in 200 consecutive patients undergoing open heart surgery. Patients were divided into 5 groups according to the inotropic drug administration as follows: Group A (n = 46) received dopamine alone; Group B (n = 40), dopamine and dobutamine; Group C (n = 36), dopamine, dobutamine, and adrenaline; Group D (n = 32), adrenaline alone; and Group E (n = 46), placebo.

Near-infrared spectroscopy monitoring of the spinal cord during type B aortic dissection surgery.

Near-infrared spectroscopy (NIRS) is a noninvasive continuous monitoring method for measuring the oxyhemoglobin saturation of the brain tissue. NIRS monitoring can suggest neuronal hypoxia in the frontal-brain before irreversible impairment of cellular metabolism. We report two cases of Type B aortic dissection surgery in which spinal regional perfusion monitoring was performed by placing two NIRS sensors on the back-skin through T6-T8 and T9-T11 vertebraes.

Giant cardiac lipoma: report of a case.

Cardiac lipomas are extremely rare benign tumors. We report a case of a 41-year-old man who was admitted because of cardiomegaly and a feeling of discomfort in his chest. Computed tomography and magnetic resonance imaging studies showed a large mass occupying the mediastinum and pericardial space.
