Background: Cerebral oximetry using near-infrared spectroscopy (NIRS) has well-documented benefits during cardiac surgery. The authors tested the hypothesis that NIRS technology can be used at other sites as a tissue oximeter during cardiac surgery and in the Intensive Care Unit (ICU). Aims: To establish feasibility of monitoring tissue oximetry during and after cardiac surgery, to examine the correlations between tissue oximetry values and cerebral oximetry values, and to examine correlations between oximetry values and mean arterial pressure (MAP) in order to test whether cerebral oximetry can be used as an index organ...

The number of obese patients undergoing cardiac and non cardiac surgery is rapidly increasing because they are more prone to concomitant diseases, such as diabetes, thrombosis, sleep-disordered breathing, cardiovascular and cerebrovascular diseases. Even if guidelines are already available to manage anesthesia and surgery of obese patients, the assessment of the perioperative morbidity and mortality from heart and brain disorders in morbidly obese surgical patients will be challenging in the next years. The present review will recapitulate the new mechanisms underlying the heart-brain axis vulnerability during the perioperative period in morbidly obese patients...

BACKGROUND: Hemodynamic instability frequently occurs in beach chair positioning for surgery, putting patients at risk for cerebral adverse events. This study examined whether preoperative volume loading with crystalloids alone or with a crystalloid-colloid combination can prevent hemodynamic changes that may be causative for unfavorable neurologic outcomes. METHODS: The study randomly assigned 43 adult patients undergoing shoulder surgery to 3 study groups. Each group received an infusion of 500 mL of Ringer's acetate between induction of anesthesia and being placed in the beach chair position...

Although there is no remarkable change of anesthetics or anesthesia methods in recent years, several new technologies are used for safety management of cardiac, lung or thoracic surgery. Stroke volume variation (SVV) monitoring indicates SVV, a parameter to optimize fluid infusion and is used to avoid edema or congestive heart damage due to over hydration. SmartPilot View, a pharmacokinetic simulator during anesthesia, represents the measured effective site concentration of anesthetics and contributes the optimization of induction and maintenance of anesthesia...

BACKGROUND: General anesthesia dramatically decreases the activity of the autonomic nervous system. Most of the hypnotic agents used to induce anesthesia inhibit sympathetic cardiovascular regulation and baroreflex control in a dose-dependent manner, lowering cardiac adaptability during the operation. The consequence of this effect in children during and after surgery has never been studied to date. AIM: The aim of this study was to follow the variations in autonomic cardiac indices in children younger than 8 years old after general anesthesia (6-24 hours) in programmed surgery...

Reports on pacemaker placement/relocation surgery under pectoralis nerve block are limited. We herein report a case involving a 74-year-old woman with an infected cardiac pacemaker generator who underwent pacemaker relocation surgery under an ultrasound-guided pectoralis nerve block. On preoperative evaluation, she had congestive heart failure, type 2 diabetes mellitus, and a pacer-dependent heart rhythm. She was considered to be at high risk for general anesthesia. Thus, an ultrasound-guided pectoralis nerve block was planned...

INTRODUCTION: Post-operative cognitive dysfunction (POCD) is frequent in patients older than 60 years undergoing major non-cardiac surgery, and increases both morbidity and mortality. Anesthetic drugs may exert neurotoxic effects and contribute to the genesis of POCD. The hypothesis of the POCD-ELA trial was that closed-loop target-controlled infusion of propofol and remifentanil could reduce the occurrence of POCD by decreasing the risk of excessive depth of anesthesia and the dose of anesthetic drugs...

Introduction: The risk of air microembolism during cardiopulmonary bypass (CPB) is high and influences the postoperative outcome, especially in elderly patients. The use of carbon dioxide (CO2 ) atmosphere during cardiac surgery may reduce the risk of cerebral air microembolism. The aim of our study was to assess the influence of CO2 field flooding on microembolism-induced brain damage assessed by the level of S100ß protein, regarded as a marker of brain damage. Materials and methods: A group of 100 patients undergoing planned mitral valve operation through median sternotomy using standard CPB was recruited for the study...

Dexmedetomidine, an α-2 adrenergic receptor agonist, provides analgesia, sedation, anxiolysis, sympatholysis and anesthetic-sparing effect, without inducing significant respiratory depression. Due to these properties, its clinical use is no longer limited to serving as a sedative agent in the intensive care unit. Proper airway management and the avoidance of cardiac and respiratory complications are common goals of everyday anesthesia practice. Ensuring airway safety is pivotal during the anesthesia stages of induction, maintenance and recovery...

Machine learning approaches were introduced for better or comparable predictive ability than statistical analysis to predict postoperative outcomes. We sought to compare the performance of machine learning approaches with that of logistic regression analysis to predict acute kidney injury after cardiac surgery. We retrospectively reviewed 2010 patients who underwent open heart surgery and thoracic aortic surgery. Baseline medical condition, intraoperative anesthesia, and surgery-related data were obtained. The primary outcome was postoperative acute kidney injury (AKI) defined according to the Kidney Disease Improving Global Outcomes criteria...

Transcatheter aortic valve implantation (TAVI) has evolved into a standard therapy for aged patients with severe aortic valve stenosis who are not candidates for surgery. However, the reports about the safety of TAVI for patients with dextrocardia situs inversus are few. An 84-year-old man with dextrocardia situs inversus underwent a TAVI for severe aortic stenosis (AS) with an aortic valve area of 0.5 cm2 , and a mean pressure gradient of 46 mmHg. Preoperative computed tomography (CT) revealed an inverted (rightward) orientation of the ventricle apex as well as the great vessels...

Expected values for blood pressure are known for both unanesthetized and anesthetized children. The statistics of changes in blood pressure during anesthesia, which may have important diagnostic significance, have not been reported. The purpose of this study was to report the variation in changes in blood pressure in four pediatric age groups, undergoing both cardiac and non-cardiac surgery. An analysis of the changes in blood pressure using normalization and principal component analysis techniques was performed using an existing electronic dataset of intra-arterial pediatric blood pressure values during anesthesia...
