ReviewLessons Learned in Neurodevelopmental Outcomes Research in Children Following Extracorporeal Membrane Oxygenation.
Neurodevelopmental outcomes research in children following extracorporeal membrane oxygenationis a complex and evolving field. From systematic reviews to multi-center prospective cohort studies, a variety of research endeavors in this domain have already been conducted. Recent attention has redirected the focus on biomarkers and imaging studies to help better understand the neurological, developmental, and behavioral effects of extracorporeal membrane oxygenation on surviving children. This review provides an overview of major research in the field, ongoing and future studies, and a summary of lessons learned from these efforts.

Development and Performance Evaluation of a Clinical Predictive Model to Estimate the Risk of Red Blood Cell Requirements in Brain Tumor Surgery.
The identification of factors associated with perioperative red blood cell (RBC) transfusion provides an opportunity to optimize the patient and surgical plan, and to guide perioperative crossmatch and RBC orders. We examined the association among potential bleeding risk factors and RBC requirements to develop a novel predictive model for RBC transfusion in patients undergoing brain tumor surgery. ⋯ RBC requirements in patients undergoing brain tumor surgery can be estimated with acceptable accuracy using a predictive model based on readily available preoperative clinical variables. This predictive model could help to optimize both individual patients and surgical plans, and to guide perioperative crossmatch orders.

The Influence of Carbon Dioxide on Cerebral Autoregulation During Sevoflurane-based Anesthesia in Patients With Type 2 Diabetes.
Cerebral autoregulation (CA) continuously adjusts cerebrovascular resistance to maintain cerebral blood flow (CBF) constant despite changes in blood pressure. Also, CBF is proportional to changes in arterial carbon dioxide (CO 2 ) (cerebrovascular CO 2 reactivity). Hypercapnia elicits cerebral vasodilation that attenuates CA efficacy, while hypocapnia produces cerebral vasoconstriction that enhances CA efficacy. In this study, we quantified the influence of sevoflurane anesthesia on CO 2 reactivity and the CA-CO 2 relationship. ⋯ The CA-CO 2 relationship is impaired in awake patients with type 2 DM. Sevoflurane-based anesthesia does not further impair this relationship. In patients with DM, hypocapnia induces cerebral vasoconstriction, but CA efficacy does not improve as observed in healthy subjects.

Adverse Events in the Pediatric Cardiac Catheterization Suite: Does Having Pediatric Cardiac Anesthesiologists Make a Difference?
It has been suggested that anesthesiologists with subspecialty expertise in pediatric cardiac anesthesia are best qualified to care for patients with complex congenital cardiac anomalies and manage the complex physiology frequently encountered in the pediatric cardiac catheterization lab. We evaluated the incidence of adverse events in our pediatric cardiac catheterization lab, comparing care provided by cardiac and noncardiac pediatric attending anesthesiologists. ⋯ In our analysis, the incidence of adverse events in the pediatric cardiac catheterization lab during the study period was not statistically different, whether anesthesia care was provided by a cardiac or a noncardiac anesthesiologist.
