King airway

L España Fuente, P de la Rica Fernández, J L González González
Laryngeal cysts are largely asymptomatic and typically described in the context of incidental discovery on routine laryngoscopy. These cysts, in adults are even rarer and can have catastrophic consequences in an anaesthetized patient if airway management is inappropriate. We describe a case of difficult endotracheal intubation and the treatment of an adult patient with an asymptomatic, giant vallecular cyst that was discovered during rapid-sequence induction of general anesthesia in urgent surgery. In conclusion, vallecular cysts can cause extreme problems in securing the airway...

INTRODUCTION: In the prehospital setting, Emergency Medical Services (EMS) professionals rely on providing positive pressure ventilation with a bag-valve-mask (BVM). Multiple emergency medicine and critical care studies have shown that lung-protective ventilation protocols reduce morbidity and mortality. Our primary objective was to determine if a group of EMS professionals could provide ventilations with a smaller BVM that would be sufficient to ventilate patients. Secondary objectives included 1) if the pediatric bag provided volumes similar to lung-protective ventilation in the hospital setting and 2) compare volumes provided to the patient depending on the type of airway (mask, King tube, and intubation)...

Obstructive sleep apnea represents a large burden of disease to the general population and may compromise patient quality of life; workplace and automotive safety; and metabolic, cardiovascular, and neurocognitive health. The disease is characterized by repetitive cycles of upper airway collapse resulting from a lack of pharyngeal airway structural support and loss of muscle tone among upper airway dilators. Polysomnography serves as the gold standard for diagnosis of obstructive sleep apnea and the apnea-hypopnea index is the most commonly used metric for quantifying disease severity...

BACKGROUND AND OBJECTIVES: Managing the airway of post burn contracture of the neck has always been challenging to anesthesiologists as it limits the alignment of oro-pharyngo-laryngeal axes because of functional and anatomical deformities that occur as a result of long standing contractures. Here the role of the King Vision video laryngoscope which is the latest in the series of video laryngoscope has been evaluated for such patients. CASE REPORT: A 35 year old male patient with post burn contracture of neck was scheduled for release of the contracture...

BACKGROUND: World Trade Center (WTC)-exposed rescue/recovery workers endured massive respiratory insult from inhalation of particulate matter and gases, resulting in respiratory symptoms, loss of lung function, and, for many, bronchial hyperreactivity (BHR). The persistence of respiratory symptoms and lung function abnormalities has been well-documented, while persistence of BHR has not been investigated. METHODS: 173 WTC-exposed firefighters with bronchial reactivity measured within 2 years after 9/11/2001 (9/11), (baseline methacholine challenge test [MCT]), were re-evaluated in 2013-2014 (follow-up-MCT)...

BACKGROUND: 'Can't Intubate, Can't Oxygenate' is a rare but life threatening event. Anaesthetists must be trained and have appropriate equipment available for this. The ideal equipment is a topic of ongoing debate. To date cricothyroidotomy training for anaesthetists has concentrated on cannula techniques. However cases reported to the NAP4 audit illustrated that they were associated with a high failure rate. A recent editorial by Kristensen and colleagues suggested all anaesthetists must master a surgical technique...

INTRODUCTION: Performing lung function test in geriatric patients has never been an easy task. With well-established evidence indicating impaired small airway function and air trapping in patients with geriatric COPD, utilizing forced oscillation technique (FOT) as a supplementary tool may aid in the assessment of lung function in this population. AIMS: To study the use of FOT in the assessment of airflow limitation and air trapping in geriatric COPD patients. STUDY DESIGN: A cross-sectional study in a public hospital in Hong Kong...

P2Y receptor activation causes the release of inflammatory cytokines in the bronchial epithelium, whereas G protein-coupled estrogen receptor (GPER), a novel estrogen (E2) receptor, may play an anti-inflammatory role in this process. We investigated the cellular mechanisms underlying the inhibitory effect of GPER activation on the P2Y receptor-mediated Ca(2+) signaling pathway and cytokine production in airway epithelia. Expression of GPER in primary human bronchial epithelial (HBE) or 16HBE14o- cells was confirmed on both the mRNA and protein levels...

OBJECTIVE: This study attempts to determine if newer indirect laryngoscopes or intubating devices are superior to a standard laryngoscope for intubation success among helicopter emergency medical service (HEMS) personnel. METHODS: Flight nurses and paramedics intubated standardized mannequins with a normal airway, a trauma airway, and a difficult airway using a standard laryngoscope, a gum elastic bougie, the Airtraq laryngoscope (King System Corp, Noblesville, IN), the Glidescope Ranger laryngoscope (Verathon Inc, Bothell, WA), and the S...

Patients with cystic fibrosis (CF) suffer from chronic lung infection and airway inflammation. Respiratory failure secondary to chronic or recurrent infection remains the commonest cause of death and accounts for over 90% of mortality. Bacteria as Staphylococcus aureus, Pseudomonas aeruginosa and Burkholderia cepacia complex have been regarded the main CF pathogens and their role in progressive lung decline has been studied extensively. Little attention has been paid to the role of Aspergillus spp. and other filamentous fungi in the pathogenesis of non-ABPA (allergic bronchopulmonary aspergillosis) respiratory disease in CF, despite their frequent recovery in respiratory samples...

BACKGROUND AND OBJECTIVE: Cigarette smoke exposure increases airway smooth muscle (ASM) contractility. Abnormalities in peripheral airway function in smokers with normal spirometry could be due to the effects of ASM tone. We aimed to determine the contribution of ASM tone to peripheral airway function in smokers with normal spirometry from the response to bronchodilator (BD). METHODS: Ventilation heterogeneity in peripheral conductive (Scond) and acinar (Sacin) airways were measured in 50 asymptomatic smokers and 20 never-smokers using multiple breath nitrogen washout, before and 20 min after inhalation of 200 µg salbutamol and 80 µg ipratropium bromide...

BACKGROUND: Stroke is a leading cause of death and disability affecting nearly 800,000 people in the United States every year. Obstructive sleep apnea (OSA) is found in over 60% of patients with stroke/transient ischemic attack (TIA) and identified as an independent stroke risk factor in large epidemiology studies and Canadian Stroke Prevention Guidelines (SPG) but not in the United States. The 2014 Secondary SPG recommend OSA screening and treatment as a consideration only, not a requirement...

BACKGROUND: We hypothesized that the use of the channelled King VisionTM and Airtraq® would shorten the time for tracheal intubation compared with the Macintosh or GlideScope® laryngoscopes in patients with normal airways. METHODS: Eighty-six patients were randomly assigned to intubate the trachea using either the Macintosh (n=22), Glidescope® (n=21), Airtraq® (n=21), or King VisionTM (n=22) laryngoscope. The primary outcome was the time to tracheal intubation...

Studying airway smooth muscle (ASM) in conditions that emulate the in vivo environment within which the bronchi normally operate may provide important clues regarding its elusive physiological function. The present study examines the effect of lengthening and shortening of ASM on tension development in human bronchial segments. ASM from each bronchial segment was set at a length approximating in situ length (Linsitu). Bronchial tension was then measured during a slow cyclical strain (0.004Hz, from 0.7Linsitu to 1...

OBJECTIVES: Orotracheal intubation is a key component of prehospital airway management and success rates are dependent on procedural experience. Supraglottic airway devices are increasingly being used in the prehospital setting. As a result, paramedics may have fewer opportunities for performing intubation, limiting their proficiency in the procedure. We aimed to determine the trends in intubation versus supraglottic airway use over an 8 year period. We also aimed to determine the association between system-wide introduction of King LT guidelines and ETI success rates...
