Observational StudyPrevalence of Isoelectric Electroencephalography Events in Infants and Young Children Undergoing General Anesthesia.
In infants and young children, anesthetic dosing is based on population pharmacokinetics and patient hemodynamics not on patient-specific brain activity. Electroencephalography (EEG) provides insight into brain activity during anesthesia. The primary goal of this prospective observational pilot study was to assess the prevalence of isoelectric EEG events-a sign of deep anesthesia-in infants and young children undergoing general anesthesia using sevoflurane or propofol infusion for maintenance. ⋯ Isoelectric EEG events were common in infants and young children undergoing sevoflurane or propofol anesthesia. Although the clinical significance of these events remains uncertain, they suggest that dosing based on population pharmacokinetics and patient hemodynamics is often associated with unnecessary deep anesthesia during surgical procedures.

ReviewTo Infinity and Beyond: The Past, Present, and Future of Tele-Anesthesia.
Because the scope of anesthesia practice continues to expand, especially within the perioperative domain, our specialty must continually examine technological services that allow us to provide care in innovative ways. Telemedicine has facilitated the remote provision of medical services across many different specialties, but it remains somewhat unclear whether the use of telemedicine would fit within the practice of anesthesiology on a consistent basis. There have been several reports on the successful use of telemedicine within the preoperative and intraoperative realm. ⋯ This article seeks to review comprehensively the available literature related to the use of telemedicine within the preoperative, intraoperative, and postoperative phases of anesthetic care as well as analyze the major hurdles often encountered when implementing a teleconsultation service. Security of connection, data storage and encryption, federal and state medical licensure compliance, as well as overall cost/savings analysis are a few of the issues that warrant further exploration and research. As telemedicine programs develop within the perioperative arena, it is imperative for institutions to share knowledge, successes, and pitfalls to improve the delivery of care in today's technology-driven medical landscape.

Development and Multidisciplinary Preliminary Validation of a 3-Dimensional-Printed Pediatric Airway Model for Emergency Airway Front-of-Neck Access Procedures.
Pediatric-specific difficult airway guidelines include algorithms for 3 scenarios: unanticipated difficult tracheal intubation, difficult mask ventilation, and cannot intubate/cannot ventilate. While rare, these instances may require front-of-neck access (FONA) to secure an airway until a definitive airway can be established. The aim of this study was to develop a pediatric FONA simulator evaluated by both anesthesiology and otolaryngology providers, promoting multidisciplinary airway management. ⋯ The ability to practice front-of-neck emergency airway procedures safely and subsequently demonstrate proficiency on a child model has great implications regarding both quality of physician training and patient outcomes. This model may be incorporated into curricula to teach needle cricothyroidotomy and other FONA procedures to providers across disciplines.

Multicenter StudyAbility of an Arterial Waveform Analysis-Derived Hypotension Prediction Index to Predict Future Hypotensive Events in Surgical Patients.
Intraoperative hypotension is associated with worse perioperative outcomes for patients undergoing major noncardiac surgery. The Hypotension Prediction Index is a unitless number that is derived from an arterial pressure waveform trace, and as the number increases, the risk of hypotension occurring in the near future increases. We investigated the diagnostic ability of the Hypotension Prediction Index in predicting impending intraoperative hypotension in comparison to other commonly collected perioperative hemodynamic variables. ⋯ The Hypotension Prediction Index provides an accurate real time and continuous prediction of impending intraoperative hypotension before its occurrence and has superior predictive ability than the commonly measured perioperative hemodynamic variables.
