PURPOSE To review the current literature and generate recommendations on the role of newer technology in the management of the unanticipated difficult airway. METHODS A literature search using key words and filters of English language and English abstracted publications from 1990-96 contained in the Medline, Current Contents and Biological Abstracts(More)
BACKGROUND Many healthcare professionals are trained in direct laryngoscopic tracheal intubation (LEI), which is a potentially lifesaving procedure. This study attempts to determine the number of successful LEI exposures required during training to assure competent performance, with special emphasis on defining competence itself. METHODS Analyses were(More)
BACKGROUND Previously active in the mid-1990s, the Canadian Airway Focus Group (CAFG) studied the unanticipated difficult airway and made recommendations on management in a 1998 publication. The CAFG has since reconvened to examine more recent scientific literature on airway management. The Focus Group's mandate for this article was to arrive at updated(More)
PURPOSE Activated protein C (APC) is the first anti-inflammatory drug to be approved for the treatment of severe sepsis. However, the underlying mechanisms are not completely elucidated. Therefore, the aim of our study was to evaluate the effects of APC on the microcirculation (mesenteric leukocyte-endothelial interaction, plasma extravasation) using(More)
Lightwands have been used to assist in the tracheal intubation of patients with difficult airways for many years. A new lightwand (Trachlight) with a brighter light source and a flexible stylet permits both oral and nasal intubation under ambient light. This study reports the effectiveness of the Trachlight in tracheal intubation in patients with difficult(More)
Tracheal intubation under direct vision using a laryngoscope can be challenging and difficult even in experienced hands. Transillumination of the soft tissues of the neck using a lighted-stylet (lightwand) is one of many effective alternative intubating techniques developed during the past several decades. While many versions of lightwand have been(More)
(1) We examined A3 adenosine and CB1 cannabinoid receptor-coupled signaling pathways regulating Cl(-) current in a human nonpigmented ciliary epithelial (NPCE) cell line. (2) Whole-cell patch-clamp recordings demonstrated that the A3 receptor agonist, IB-MECA, activates an outwardly rectifying Cl(-)current (I(Cl,Aden)) in NPCE cells, which was inhibited by(More)
PURPOSE To evaluate the utility and safety of orotracheal intubation in adult patients with simulated difficult airways using the Bullard Laryngoscope (BL). METHODS A rigid cervical collar was used to simulate the difficult airway. The study consisted of two phases. Phase I evaluated the BL used in conjunction with an independently styletted endotracheal(More)
BACKGROUND Appropriate planning is crucial to avoid morbidity and mortality when difficulty is anticipated with airway management. Many guidelines developed by national societies have focused on management of difficulty encountered in the unconscious patient; however, little guidance appears in the literature on how best to approach the patient with an(More)
PURPOSE We sought to determine the rate of successful identification of the cricothyroid membrane by anesthesia residents and staff at a Canadian institution. METHODS In this prospective study, healthy adult volunteer subjects were positioned supine with their necks placed in neutral position. There were 12 subjects, half of whom were non-obese (body mass(More)
