A Training Program for Real-Time Ultrasound-Guided Catheterization of the Subclavian Vein.

Purpose: To develop and implement a comprehensive program to train providers to place subclavian central venous catheters (CVCs) using real-time ultrasound guidance.

Study Design: Simulation-based prospective study at an academic medical center. Of 228 anesthesia providers and intensivists eligible to participate, 106 participants voluntarily enrolled.

Misinterpreting Paced Heart Rhythms: A Case Report.

We describe 2 cases in which failure to properly interpret paced heart rhythms in patients with cardiac implantable electronic devices (CIEDs) undergoing surgery resulted in adverse consequences including unnecessary invasive procedures, surgical delays, and patient dissatisfaction. Both cases occurred even though experienced clinicians were involved, and all perioperative recommendations were followed. Although it is sometimes argued that anesthesiologists are not directly responsible for CIED management, they are often held accountable when problems arise.

Electromagnetic Interference With an Underbody Dispersive Electrode in a Patient With an Implantable Cardioverter-Defibrillator Undergoing Noncardiac Surgery: A Case Report.

During surgery, cardiac implantable electronic device (CIED) function may be disrupted by electromagnetic interference (EMI) from monopolar electrosurgery and cause adverse sequelae. Monopolar electrosurgery requires a dispersive electrode. While a conventional electrode is affixed to the patient, use of "underbody" electrodes placed on the operating table is increasing.

A Comprehensive Update on Aspirin Management During Noncardiac Surgery.

Aspirin is considered critical lifelong therapy for patients with established cardiovascular (CV) disease (including coronary artery, cerebrovascular, and peripheral arterial diseases) and is consequently one of the most widely used medications worldwide. However, the indications for aspirin use continue to evolve and recent trials question its efficacy for primary prevention. Although one third of patients undergoing noncardiac surgery and at risk for a major adverse CV event receive aspirin perioperatively, uncertainty still exists about how aspirin should be optimally managed in this context, and significant practice variability remains.

A population based analysis of trends, risk factors and outcomes associated with gastrointestinal bleeding in patients with left ventricular assist devices.

Prior to the utilization of continuous flow (CF) devices in 2010, Gastrointestinal (GI) bleeding was a common adverse event related to left ventricular assist device (LVADs) that was found to be even more frequent when CF devices were first introduced. Given the drastic increase in the use of new CF-LVADs, we sought to determine if CF-LVADs are associated with an increased number of GI bleeds and higher mortality. We analysed the data from a national inpatient sample database using the ICD-9 procedure code for LVAD use in end-stage heart failure among patients > 18 years.

Epinephrine-induced electrical storm after aortic surgery.

Electrical storm (ES) is a potentially lethal syndrome defined as three or more sustained episodes of ventricular tachycardia or ventricular fibrillation within 24 h. There are multiple inciting factors for ES, one of which involves excess catecholamine (endogenous and exogenous) effects. Exogenous catecholamines used for hemodynamic support can paradoxically engender or exacerbate an underling arrhythmia leading to ES.

A Narrative Review for Anesthesiologists of the 2017 American Heart Association/American College of Cardiology/Heart Rhythm Society Guideline for Management of Patients With Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death.

This is a review of the 2017 AHA/ACC/HRS Guidelines with guidance for intraoperative physicians. Ventricular arrhythmias occurring during the perioperative period have the potential for significant morbidity and mortality. Hence, an in-depth knowledge of VA mechanisms, prevention, and management is crucial for all clinicians caring for these at-risk patients in the perioperative period.

Electromagnetic Interference with Protocolized Electrosurgery Dispersive Electrode Positioning in Patients with Implantable Cardioverter Defibrillators.

What We Already Know About This Topic: Electromagnetic interference from monopolar electrosurgery may disrupt implantable cardioverter defibrillators.Current management recommendations by the American Society of Anesthesiologists and Heart Rhythm Society are based on expert clinical opinion since there is a paucity of data regarding the risk of electromagnetic interference to implantable cardioverter defibrillators during surgery.

What This Article Tells Us That Is New: With protocolized electrosurgery dispersive electrode positioning in patients with implantable cardioverter defibrillators, the risk of clinically meaningful electromagnetic interference was 7% in above-the-umbilicus noncardiac surgery and 0% in below-the-umbilicus surgery.

External Defibrillator Damage Associated With Attempted Synchronized Dual-Dose Cardioversion.

The simultaneous use of 2 external defibrillators to administer either dual or sequential cardioversion or defibrillation for refractory cardiac arrhythmias is increasing in both the out-of-hospital and inhospital settings. Using 2 defibrillators to administer higher energy levels than can be achieved with a single defibrillator is considered off-label and is currently not part of published advanced cardiac life support guidelines. We report the first case in which the use of dual-dose cardioversion was associated with external defibrillator damage.

Process Improvement Initiative for the Perioperative Management of Patients With a Cardiovascular Implantable Electronic Device.

Background: Economic, personnel, and procedural challenges often complicate and interfere with efficient and safe perioperative care of patients with cardiovascular implantable electronic devices (CIEDs). In the context of a process improvement initiative, we created and implemented a comprehensive anesthesiologist-run perioperative CIED service to respond to all routine requests for perioperative CIED consultations at a large academic medical center. This study was designed to determine whether this new care model was associated with improved operating room efficiency, reduced institutional cost, and adequate patient safety.

Stroke, Major Bleeding, and Mortality Outcomes in Warfarin Users With Atrial Fibrillation and Chronic Kidney Disease: A Meta-Analysis of Observational Studies.

Background: The use of warfarin in patients with atrial fibrillation (AF) and chronic kidney disease (CKD) can be problematic because of increased bleeding risk. We performed a systematic review and meta-analysis of observational studies that evaluated the use of warfarin in patients with AF and CKD to evaluate the risks of ischemic stroke/thromboembolism, major bleeding, and mortality.

Methods: PUBMED, EMBASE, CINAHL, ProQuest, and Google Scholar databases were electronically searched through January 12, 2015.

Normal Variant T-Wave Changes in an Athlete with Structurally Normal Cardiac Anatomy and Function.

Athletes who perform regular and intensive physical activity may undergo structural and electrical remodeling of the heart that results in electrocardiographic changes that can cause concern. Marked T-wave inversion may represent one such physiologic change. On the other hand, T-wave inversion could be a sign of inherited heart muscle disease or may be a normal variant.

Perioperative aspirin management after POISE-2: some answers, but questions remain.

Aspirin constitutes important uninterrupted lifelong therapy for many patients with cardiovascular (CV) disease or significant (CV) risk factors. However, whether aspirin should be continued or withheld in patients undergoing noncardiac surgery is a common clinical conundrum that balances the potential of aspirin for decreasing thrombotic risk with its possibility for increasing perioperative blood loss. In this focused review, we describe the role of aspirin in treating and preventing cardiovascular disease, summarize the most important literature on the perioperative use of aspirin (including the recently published PeriOperative ISchemic Evaluation [POISE]-2 trial), and offer current recommendations for managing aspirin during the perioperative period.
