    Variation in the Type, Rate, and Selection of Patients for Out-of-hospital Airway Procedures Among Injured Children and Adults

    ACADEMIC EMERGENCY MEDICINE, Issue 12 2009
    Craig D. Newgard MD
    Abstract Objectives:, The objective was to compare the type, rate, and selection of injured patients for out-of-hospital airway procedures among emergency medical services (EMS) agencies in 10 sites across North America. Methods:, The authors analyzed a consecutive patient, prospective cohort registry of injured adults and children with an out-of-hospital advanced airway attempt, collected from December 1, 2005, through February 28, 2007, by 181 EMS agencies in 10 sites across the United States and Canada. Advanced airway procedures were defined as orotracheal intubation, nasotracheal intubation, supraglottic airway, or cricothyrotomy. Airway procedure rates were calculated based on age-specific population values for the 10 sites and the number of injured patients with field physiologic abnormality (systolic blood pressure of ,90 mm Hg, respiratory rate of <10 or >29 breaths/min, Glasgow Coma Scale [GCS] score of ,12). Descriptive measures were used to compare patients between sites. Results:, A total 1,738 patients had at least one advanced airway attempt and were included in the analysis. There was wide variation between sites in the types of airway procedures performed, including orotracheal intubation (63% to 99%), supraglottic airways (0 to 27%), nasotracheal intubation (0 to 21%), and cricothyrotomy (0 to 2%). Use of rapid sequence intubation (RSI) varied from 0% to 65%. The population-adjusted rates of field airway intervention (by site) ranged from 1.2 to 22.8 per 100,000 adults and 0.2 to 4.0 per 100,000 children. Among trauma patients with physiologic abnormality, some sites performed airway procedures in almost 50% of patients, while other sites used these procedures in fewer than 10%. There was also large variation in demographic characteristics, physiologic measures, mechanism of injury, mode of transport, field cardiopulmonary resuscitation, and unadjusted mortality among airway patients. Conclusions:, Among 10 sites across North America, there was wide variation in the types of out-of-hospital airway procedures performed, population-based rates of airway intervention, and the selection of injured patients for such procedures.

    In vitro study of magnetic resonance imaging artefacts of six supraglottic airway devices

    ANAESTHESIA, Issue 6 2010
    M. Zaballos
    Summary We investigated the artefacts created during magnetic resonance imaging by five different laryngeal mask airways: the Classic (cLMAÔ); the LMA ProSealÔ; the LMA UniqueÔ; the Ambu® Disposable Laryngeal Mask; the LMA SupremeÔ; and one other supraglottic airway device, the i-gel supraglottic airway. The devices were placed on top of and inside a phantom simulator to resemble the position in vivo. The artefacts with the cLMA, Unique and Supreme were similar and related to ferromagnetic material in the pilot balloon valve. Artefacts were more prominent with the ProSeal. There were no artefacts with the Ambu Disposable Laryngeal Mask or the i-gel. [source]

    A randomised crossover trial comparing the i-gel supraglottic airway and classic laryngeal mask airway,

    ANAESTHESIA, Issue 6 2009
    C. Janakiraman
    Summary In a randomised cross-over study, we compared the performance of the single use i-gel supraglottic airway and reusable classic laryngeal mask airway (cLMATM) in 50 healthy anaesthetised patients who were breathing spontaneously. Primary outcome was successful insertion at first attempt. Secondary outcomes included overall insertion success rate, ease of insertion, leak pressure and fibreoptic position. Success rate for insertion at the first attempt was significantly different (54% with i-gel vs 86% with cLMA; p = 0.001). Overall success after two attempts (when the anaesthetist was allowed to change the size of the device) improved to 84% with i-gel vs 92% with cLMA; p = 0.22. In 14 patients, the i-gel when used first needed to be replaced with a larger size. Leak pressure was higher for the i-gel (median [IQR] 20 [14,24] cm H2O than the cLMA 17 [12,22] cm H2O; p = 0.023). The fibreoptic view through the device was significantly better with the i-gel than the cLMA, which was statistically significant (p = 0.03). We conclude that, with its current sizing recommendations, the i-gel is not an acceptable alternative to cLMA. However because of the significantly improved success rate after a larger sized i-gel was used, we recommend the manufacturer to review the sizing guidelines to improve the success rate. [source]
