    A Case Report: Establishing a Definitive Airway in a Trauma Patient With a King Laryngeal Tube In Situ in the Presence of a Closed Head Injury and Difficult Airway: "Between the Devil and the Deep Blue Sea".
    A A Case Rep 2017 Mar;8(6):139-141
    From the *Department of Anesthesiology and Perioperative Medicine, Queen's University, Kingston General Hospital, Kingston, Ontario, Canada; and †Department of Otolaryngology, Queen's University, Hotel Dieu Hospital, Kingston, Ontario, Canada.
    Airway management in trauma is a crucial skill, because patients are at risk of aspiration, hypoxia, and hypoventilation, all of which may be fatal in the setting of increased intracranial pressure. The King Laryngeal Tube reusable supraglottic airway (King Systems, Noblesville, IN) allows for temporary management of a difficult airway but poses a challenge when an attempt is made to exchange the device for an endotracheal tube, often managed by emergency tracheostomy. We describe a novel fiberoptic, video laryngoscope-assisted approach to intubation in a difficult trauma airway with an in situ King Laryngeal Tube. Read More

    Left Ventricular Assist Device Insertion in a Patient With Biventricular Noncompaction Cardiomyopathy, Ebstein Anomaly, and a Left Atrial Mass: A Case Report.
    A A Case Rep 2016 Dec;7(12):251-255
    From the Department of Anesthesiology, Allegheny Health Network, Pittsburgh, Pennsylvania.
    In this report, we present the case of a patient with biventricular noncompaction cardiomyopathy, Ebstein anomaly, and a left atrial mass who required emergent placement of a left ventricular assist device. The noncompaction cardiomyopathy complicated the left ventricular assist device implantation procedure because the thickened, trabeculated myocardium made it difficult to place the inflow cannula. We discuss our perioperative management strategy, in which transesophageal echocardiography was used, to help the surgical team identify the proper cannula placement and provide a bridge to transplantation.

    Intraoperative Autotriggered Pressure Support Ventilation Resistant to Increased Flow Trigger Threshold.
    A A Case Rep 2016 Jul;7(1):9-12
    From the Department of Anesthesiology, Perioperative Medicine, and Pain Management, University of Miami, Miami, Florida.
    Oscillations from cardiac pulsations are normally transmitted to mediastinal structures without any consequence. Autotriggering (AT) of mechanical ventilation occurs when an inspiratory trigger, typically negative inspiratory flow in anesthesia ventilators, is met in the absence of patient effort. AT can lead to respiratory alkalosis, opioid overdose, prolonged mechanical ventilation, and lung hyperinflation. Read More

    In the Aftermath: Attitudes of Anesthesiologists to Supportive Strategies After an Unexpected Intraoperative Patient Death.
    Anesth Analg 2016 May;122(5):1614-24
    From the *Department of Anaesthesia and Acute Pain Medicine, St Vincent's Hospital, Melbourne, Victoria, Australia; †Western Health, Melbourne, Victoria, Australia; ‡Anaesthesia, Perioperative and Pain Medicine Unit, Melbourne Medical School, University of Melbourne; and §Schools of Psychology, Information Technology and Electrical Engineering, and Medicine, The University of Queensland, St Lucia, Queensland, Australia.
    Background: Although most anesthesiologists will have 1 catastrophic perioperative event or more during their careers, there has been little research on their attitudes to assistive strategies after the event. There are wide-ranging emotional consequences for anesthesiologists involved in an unexpected intraoperative patient death, particularly if the anesthesiologist made an error. We used a between-groups survey study design to ask whether there are different attitudes to assistive strategies when a hypothetical patient death is caused by a drug error versus not caused by an error.

    First-Attempt Intubation Success of Video Laryngoscopy in Patients with Anticipated Difficult Direct Laryngoscopy: A Multicenter Randomized Controlled Trial Comparing the C-MAC D-Blade Versus the GlideScope in a Mixed Provider and Diverse Patient Population.
    Anesth Analg 2016 Mar;122(3):740-50
    From the *Department of Anesthesiology & Perioperative Medicine, Oregon Health & Science University, Portland, Oregon; †Department of Anesthesia, University of Iowa, Iowa City, Iowa; and ‡Department of Anesthesiology, University of Texas at Houston, Houston, Texas.
    Background: Intubation success in patients with predicted difficult airways is improved by video laryngoscopy. In particular, acute-angle video laryngoscopes are now frequently chosen for endotracheal intubation in these patients. However, there is no evidence concerning whether different acute-angle video laryngoscopes can be used interchangeably in this scenario and would allow endotracheal intubation with the same success rate.

    Initial Experience of an Anesthesiology-based Service for Perioperative Management of Pacemakers and Implantable Cardioverter Defibrillators.
    Anesthesiology 2015 Nov;123(5):1024-32
    From the Department of Anesthesiology and Pain Medicine (G.A.R., S.A.L., G.A.V.N., J.D., K.M.N.) and Division of Cardiology, Department of Medicine (L.W.L., J.E.P.), University of Washington, Seattle, Washington.
    Background: Management of cardiovascular implantable electronic devices (CIEDs), including pacemakers and implantable cardioverter defibrillators, for surgical procedures is challenging due to the increasing number of patients with CIEDs and limited availability of trained providers. At the authors' institution, a small group of anesthesiologists were trained to interrogate CIEDs, devise a management plan, and perform preoperative and postoperative programming and device testing whenever necessary.

    Methods: Patients undergoing surgery between October 1, 2009 and June 30, 2013 at the University of Washington Medical Center were included in a retrospective chart review to determine the number of devices actively managed by the Electrophysiology/Cardiology Service (EPCS) versus the Anesthesiology Device Service (ADS), changes in workload over time, surgical case delays due to device management, and errors and problems encountered in device programming.
