End-stage renal disease (ESRD) is associated with significant alterations in cardiovascular function; homeostasis of body fluid, electrolytes, and acid-base equilibrium; bone metabolism, erythropoiesis; and blood coagulation. The prevalence of ESRD is increasing rapidly worldwide, as is the number of patients requiring surgery under general anesthesia. Patients with ESRD have significantly higher risks of perioperative morbidity and mortality due to multiple comorbidities. The perioperative management of patients with ESRD under general anesthesia therefore requires special considerations and a careful multidisciplinary approach...

This study evaluates whether immature platelets (IPF) determined in the post anesthesia care unit (PACU) can predict major adverse cardiovascular events (MACE) or other thromboembolic events after intermediate and high-risk surgery. IPF are increased in patients with acute coronary syndrome and recently gained interest as novel biomarker for risk stratification. In this prospective observational trial 732 patients undergoing intermediate or high-risk non-cardiac surgery were enrolled (NCT02097602). IPF was measured preoperatively and postoperatively in the PACU...

Objective: To evaluate the efficacy of endotracheal tube for drug injection in postoperative ICU patients. Methods: A total of 60 ICU patients who were given mechanical ventilation after surgical treatment were enrolled in this study from January 2015 to August 2016 at our hospital. All the patients were divided into the observation group (30 cases) and the control group (30 cases). In the observation group, the patients were treated with the endotracheal tube for surface anesthesia by injecting 2% lidocaine into the trachea, and patients in the control group were treated with saline instead of lidocaine...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is typically performed under general anesthesia (GA). However, there is increasing data supporting the safety of performing TAVR under local anesthesia/conscious sedation (LA). We performed a meta-analysis to gain better understanding of the safety and efficacy of LA versus GA in patients with severe aortic stenosis undergoing TAVR. METHODS AND RESULTS: We comprehensively searched EMBASE, PubMed, and Web of Science...

BACKGROUND: The current American Society of Regional Anesthesia (ASRA) guidelines recommend discontinuing anti-thrombotic therapy prior to any interventional spine procedures to decrease the incidence of bleeding complications. However, discontinuing anti-thrombotics may pose considerable danger in terms of cerebrovascular and cardiovascular events. Recent evidence suggests that some spinal interventions may still be performed safely with anti-thrombotics on board and some practitioners thus elect to continue certain anti-thrombotics for these procedures...

Mucopolysaccharidosis type VII (MPS VII) is caused by β-glucuronidase deficiency, resulting in lysosomal accumulation of glycosaminoglycans (GAGs) and multisystemic disease. We present cardiovascular gross and histopathology findings from a 11-year-old MPS VII male, who expired after developing ventricular fibrillation following anesthesia induction. Gross anatomic observations were made at autopsy; postmortem formalin-fixed paraffin-embedded samples of the carotid artery, aorta, myocardium, and valves were sectioned and stained with hematoxylin-eosin, Verhoeff-Van Gieson, CD68, and trichrome stains...

BACKGROUND: Arytenoid cartilage dislocation/subluxation is one of the rare complications following tracheal intubation, and there have been no reports about risk factors leading this complication. From our clinical experience, we have an impression that patients undergoing cardiovascular operations tend to be associated with this complication. AIMS: We designed a large retrospective study to reveal the incidence and risk factors predicting the occurrence and to examine whether our impression is true...

OBJECTIVE: To update national population-level pregnancy-related mortality estimates and examine characteristics and causes of pregnancy-related deaths in the United States during 2011-2013. METHODS: We conducted an observational study using population-based data from the Pregnancy Mortality Surveillance System to calculate pregnancy-related mortality ratios by year, age group, and race-ethnicity groups. We explored 10 cause-of-death categories by pregnancy outcome during 2011-2013 and compared their distribution with those in our earlier reports since 1987...

The biomedical research enterprise depends on the fair and objective peer review of research grants, leading to the distribution of resources through efficient and robust competitive methods. In the United States, federal funding agencies and foundations collectively distribute billions of dollars annually to support biomedical research. For the American Heart Association, a Peer Review Subcommittee is charged with establishing the highest standards for peer review. This scientific statement reviews the current literature on peer review practices, describes the current American Heart Association peer review process and those of other agencies, analyzes the strengths and weaknesses of American Heart Association peer review practices, and recommends best practices for the future...

OBJECTIVES: This investigation explores flow disruptions observed during cardiothoracic surgery and how they serve to disconnect anesthesia providers from their primary task. We can improve our understanding of this disengagement by exploring what we call the error space or the accumulated time required to resolve disruptions. METHODS: Trained human factors students observed 10 cardiac procedures for disruptions impacting the anesthesia team and recorded the time required to resolve these events...

REVIEW

Hypotension commonly occurs in parturients undergoing cesarean delivery under spinal anesthesia. This leads to maternal and neonatal adverse outcomes, including maternal nausea and vomiting and fetal acidosis, and might even lead to cardiovascular collapse if not treated. Arterial dilatation and reduction in systemic vascular resistance are the major contributors to spinal-induced hypotension. Therefore, strategies aimed at expanding the intravascular volume with fluid loading or increasing venous return with lower extremities mechanical compression and lateral tilt have had limited effectiveness in the management of spinal-induced hypotension...

Embolic events including thromboembolism, air embolism, and amniotic fluid embolism can cause cardiovascular collapse during cesarean delivery. Differentiation between the three conditions is challenging because they share many of the initial clinical and echocardiographic findings, but an accurate, definitive diagnosis allows the administration of specific therapy that may help in saving the life of the mother and/or the fetus. We report a case of cardiovascular collapse during cesarean delivery under general anesthesia; massive pulmonary thromboembolism was suspected and unfractionated heparin was administered...

Significant individual susceptibility to intravenous anesthetic propofol exists. The etiology of individual variability in the response to propofol may be influenced by genetic polymorphisms in metabolic and functional pathways. With current pharmacogenetics and modern molecular biology technologies, it is possible to study the influence of genetic polymorphisms on susceptibility to propofol. When inducing general anesthesia with intravenous propofol, high individual susceptibility to propofol was found. Using Sequenom MassARRAY single-nucleotide polymorphism (SNP) genotyping, we identified a mutation (rs6313) in the 5HT2A gene that was correlated to individual susceptibility to propofol effect-site concentration (Cep) and onset time of propofol induction...

BACKGROUND: Postoperative cognitive dysfunction (POCD), common in elderly patients, is thought to be closely associated with intraoperative instability of hemodynamics and excessive excretion of tumor necrosis factor-α (TNF-α). Methoxamine is a blood-pressure increasing drug commonly used for maintaining intraoperative hemodynamics. Methoxamine potentially promotes TNF-α expression, leading to an increased risk of POCD. This study aimed to investigate the dose-dependent effect of methoxamine on the incidence of early POCD and blood TNF-α level...

The existing clinical studies on remote ischemic preconditioning in patients undergoing cardiovascular surgery are critically reviewed, with a focus on infarct size reduction and clinical outcome as end points. Confounders, notably the use of propofol anesthesia are identified. The need for better designed trials with a more targeted approach is emphasized.
