Randomized Controlled Trial Multicenter Study Comparative StudyComparison of Inhalational and Intravenous Anesthesia Induction on Electroencephalogram and Cerebral Perfusion in Children With Congenital Heart Disease: A Secondary Analysis of a Randomized Controlled Trial.
The effects of anesthetics on electroencephalograms and cerebral perfusion remain understudied in children with congenital heart disease. With regard to this, we compared inhalational anesthesia induction and intravenous anesthesia induction. ⋯ The administration of sevoflurane for anesthesia induction results in more burst suppression, while also demonstrating superior cerebral perfusion when compared with the use of intravenous medications for anesthesia induction.

Observational StudyReduction in Postoperative Right Ventricular Echocardiographic Indices Predicts Longer Duration of Vasoactive Support After Cardiac Surgery.
To assess perioperative right ventricular (RV) echocardiographic indices and their relationship to vasopressor and inotropic support in cardiac surgical patients. The authors hypothesized that a reduction in echocardiographic parameters of RV function would be associated with a longer duration of vasopressor and inotropic support in the intensive care unit (ICU). ⋯ Patients with post-CPB TAPSE <17 mmHg require a longer duration of inotropic support in the ICU. From all measured RV echocardiographic indices, post-CPB FAC is an independent predictor of vasopressor and inotropic support. A reduction of post-CPB TAPSE and FAC in patients undergoing cardiac surgery is indicative of RV dysfunction requiring a longer use of vasopressor and inotropic support and potentially longer stay in the cardiovascular ICU.

ReviewTwo Is Better than One: Aveir DR Leadless Pacemaker System with Dual-Chamber Pacing.
The Aveir DR dual-chamber Leadless Pacemaker system (Abbott Laboratories) was recently approved by the US Food and Drug Administration and is heralded to be the next generation of leadless pacemakers. Earlier generations of leadless pacemakers could only provide single-chamber right ventricular pacing, limiting their application to a small subset of patients in whom pacemaker therapy is indicated. ⋯ Although there have been prior documented experiences with the earlier generation of leadless pacemakers, the addition of a second leadless pacemaker to provide dual-chamber pacing adds new complexities. It is essential to understand what makes the Aveir DR system unique if an anesthesiologist were to come across one perioperatively.
