Case ReportsThe management and outcome of documented intraoperative heart rate-related electrocardiographic changes.
The authors analyzed surgical cases in which electrocardiographic (ECG) signs of cardiac ischemia were noted to be precipitated by increases in heart rate (ie, heart rate-related ECG changes [REC]). The authors aimed to find REC incidence, specificity for coronary artery disease (CAD), and the outcome associated with different management strategies. ⋯ This incidence of reported REC was much lower than the previously reported incidence of ischemia-related ECG changes, suggesting that the largest proportion of events go unnoticed. In many patients, subsequent cardiology workup did not confirm the existence of clinically significant CAD.

HbA1c and diabetes predict perioperative hyperglycemia and glycemic variability in on-pump coronary artery bypass graft patients.
Perioperative hyperglycemia and glycemic variability are considered independent predictors of morbidity and mortality in critically ill patients. The purpose of this study was to investigate the relation of HbA1c and/or a prior diagnosis of diabetes mellitus and intra- and postoperative hyperglycemia and glycemic variability. ⋯ Diabetic status and/or elevated HbA1c are predictors of postoperative glucose variability and hyperglycemia in CABG surgery patients. However, in the intraoperative period, these groups show similar glycemic responses to operative stress.

Scholarly productivity of united states academic cardiothoracic anesthesiologists: influence of fellowship accreditation and transesophageal echocardiographic credentials on h-index and other citation bibliometrics.
The h-index allows the evaluation of scholarly output in academics, but this bibliometric statistic has not been applied extensively to measure productivity in anesthesiology. The authors tested the hypothesis that the h-index is dependent on academic rank, American College of Graduate Medical Education (ACGME) accreditation of the training program, and National Board of Echocardiography credentials in perioperative transesophageal echocardiography (TEE) in United States academic cardiothoracic anesthesiologists. ⋯ The results show that the h-index increases progressively with academic rank and is dependent on fellowship program accreditation status but not transesophageal echocardiographic credentials in United States academic cardiothoracic anesthesiologists.
