IMPLICATIONS The ProSeal and classic laryngeal mask airways are equally effective ventilatory devices in healthy female patients at tidal volumes of 8 and 12 mL/kg with the cuff semi- or fully inflated, but leakage of small volumes of air from the mouth occurs more frequently with the laryngeal mask airway.

Introduction Internal neck anatomy landmarks and their relation after placement of an extraglottic airway devices have not been studied extensively by the use of ultrasound. Based on our group experience with external landmarks as well as internal landmarks evaluation with other techniques, we aimed use ultrasound to analyze the internal neck anatomy landmarks and the related changes due to the...

T he laryngeal mask airway (LMA) is accepted as both a rescue ventilation and a primary airway management device in both the prehospital and emergency department environments. A modified version of the LMA, the intubating laryngeal mask airway (ILMA, LMA-Fastrach; Intavent Ltd, Reading, UK) exists, which, when combined with a modified tracheal tube, can be used for blind tracheal intubation. Th...

BACKGROUND The LMA-Classic laryngeal mask airway (Classic LMA) is an autoclavable and reusable laryngeal mask airway with strong evidence supporting its efficacy and safety. Due to the concern of infection risk particularly of prion disease, various single-use laryngeal mask devices were developed. The Ambu AuraOnce LMA (Ambu LMA) is a single use disposable laryngeal mask airway with special de...
