BACKGROUND Tracheal intubation via laryngoscopy is a fundamental skill, particularly for anaesthesiologists. However, teaching this skill is difficult since direct laryngoscopy allows only one individual to view the larynx during the procedure. The purpose of this study was to determine if video-assisted laryngoscopy improves the effectiveness of tracheal(More)
BACKGROUND The clinical utility of focused transthoracic echocardiography (TTE) is increasingly recognized in perioperative medicine. However its use is limited among anesthesiologists because of a lack of training. The most efficient training methods have not been determined. We hypothesized that simulation-based TTE training would be more effective than(More)
BACKGROUND Anesthesiologists are responsible for the management of perioperative cardiopulmonary arrest in children. This study used simulation to assess the pediatric resuscitation skills of experienced anesthesia residents. METHODS Nineteen anesthesia residents were evaluated using a pediatric pulseless electrical activity scenario. The authors used a(More)
Since the advent of neonatal cardiac surgery in the 1970s, an increasing number of patients suffering from congenital heart disease (CHD) have survived into adulthood. In 2010, it is estimated that 1.2 million or 1 in 150 of young adults have some form of CHD in the United States. Current birth, incidence, and survival rate predict an increase in the CHD(More)
Sympathoexcitation is associated with ventricular arrhythmogenesis. The aim of this study was to determine the role of thoracic dorsal root afferent neural inputs to the spinal cord in modulating ventricular sympathetic control of normal heart electrophysiology. We hypothesize that dorsal root afferent input tonically modulates basal and evoked efferent(More)
BACKGROUND Imbalances in the autonomic nervous system, namely, excessive sympathoexcitation, contribute to ventricular tachyarrhythmias. While thoracic epidural anesthesia clinically suppresses ventricular tachyarrhythmias, its effects on global and regional ventricular electrophysiology and electrical wave stability have not been fully characterized. The(More)
BACKGROUND Red blood cell (RBC) transfusions are associated with increased morbidity. Children receiving heart transplants constitute a unique group of patients due to their risk factors. Although previous studies in nontransplant patients have focused primarily on the effects of postoperative blood transfusions, a significant exposure to blood occurs(More)
OBJECTIVES The primary aim of this study was to use speckle-tracking strain imaging to evaluate the effect of general anesthesia (GA) and positive-pressure ventilation (PPV) on left atrial (LA) mechanics. The authors hypothesized that GA and PPV would be associated with a decrease in LA strain. The secondary aims were to investigate the effects of GA and(More)
