The laryngeal mask airway (LMA) is a relatively new device that was brought into clinical practice in the 1980s. It was conceived, designed, and developed between 1981 and 1988 by Dr. Archie Brain, a British anesthesiologist who felt that a component for airway management was missing. The laryngeal mask was conceived to provide the bridge between the face mask and the endotracheal tube. The con...

Editor—We thank Dr Langer and colleagues for their thoughtful comments on our article and agree that it is important to implement protocols for the management of patients with CIEDs undergoing a variety of both surgical and non-surgical procedures. Dr Langer and colleagues should be congratulated for their efforts in doing so. It is clear that their established protocol maintains patient safety...

BACKGROUND The ProSeal is a wire-reinforced laryngeal mask airway with an additional drain tube that leads to the distal tip of the laryngeal cuff. The design should improve the seal with the larynx. METHODS The ProSeal and classic laryngeal mask airways were compared in 180 patients in a randomized crossover study. Patients were anaesthetized without neuromuscular blocking drugs. RESULTS T...

Managing the airway of a critically injured trauma patient in the prehospital environment is challenging, especially when access to the patient's airway is limited as is often the case in vehicle entrapment incidents. This paper reports the use of the laryngeal mask airway as an adjunct to airway management when attempts using simple airway management techniques have failed to provide adequate ...

Journal of Anaesthesiology Clinical Pharmacology | Volume 33 | Issue 2 | April-June 2017 265 functionality of the anesthesia machines and circuits need to be vigilantly monitored by the anesthesiologists timely to avoid such catastrophes. We should keep the vicinity around APL valve clear and free of any tubings or loose wires, thus avoiding its malfunction. We would suggest that the working ma...

We have confirmed the value of measurement of end-tidal carbon dioxide concentration as an indicator of arterial carbon dioxide tension during the use of the laryngeal mask airway in healthy patients breathing spontaneously. The mean difference between arterial and end-tidal carbon dioxide tension was 0.52 kPa (range 0-1.5 kPa), which is similar to the difference which has been reported when a ...

erative mortality was only 0.5%; in contrast, in those who received 61-80 U and more than 80 U, mortality was 70% and 86%, respectively. The LD50 for blood administration was approximately 58 U of blood. Our analysis does not address the precise factors that contribute to early postoperative mortality after OLT. Although there are certainly a multitude of factors (preoperative, intraoperative, ...

BACKGROUND Novel laryngoscopes may demonstrate advantages over the traditional Macintosh laryngoscope for difficult airways. Our study compared Glidescope laryngoscope, Bonfils fibrescope, and CTrach intubating laryngeal mask airway with the Macintosh laryngoscope in a simulated normal and difficult airway, considering the additional effect of previous intubation experience. METHODS Twenty-tw...

OBJECTIVE Training students on simulators before allowing their direct contact with patients is well accepted. There is no clinical or manikin-based simulation study in the literature comparing tracheal intubation with Airtraq, laryngeal mask airway (LMA) CTrach and Macintosh laryngoscopes performed by medical students having no prior intubation experience. METHODS After obtaining written inf...
