Brain AIJ, Denman WT, Goudsouzian NG (1999). LMA is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary The laryngeal mask was invented by British anaesthesiologist/anaesthetist Archibald Brain in the early 1980s and in December 1987 the first commercial laryngeal mask was made available in the United Kingdom. The laryngeal mask had now been widely accepted as a form of airway management.[7]. Finding no difference between the first and second group of patients, Brain realised that muscle relaxtion was not required for insertion. After correct insertion, the tip of the laryngeal mask sits in the throat against the muscular valve that is located at the upper portion of the esophagus. Insertion and ventilation using the laryngeal mask in 16 anaesthetised, paralysed female patients was successful, achieving a seal greater than 20 cm H2O in all patients. Between 1989 and 2000 a variety of specialised laryngeal masks were released which included the LMA Flexible (1990), LMA Fastrach (1997), LMA Unique (1997) and LMA ProSeal (2000), all offered by The Laryngeal Mask Company. Guidelines for cardiopulmonary resuscitation and emergency cardiovascular care. [6], On 5 December 1987, Brain received the first case of all-factory-made, silicone cuffed, LMA Classic laryngeal mask distributed by The Laryngeal Mask Company Limited. 10, Joseph R. Brimacombe, Laryngeal Mask Airway: Principles and Practice, Second Edition (2005), pp.

The silicone Dunlop prototype was superior to the Goldman prototype, one of Brains first prototypes created from the cuff of a latex Goldman dental mask, however Brain needed a material that would give him design flexibility before the next set of silicone moulds were cast. In 1986, Brain continued to make prototypes from latex with a range of modifications; the inclusion of an inflation line, a thin-walled elliptical ring in the cuff which resulted in equal expansion of the cuff, the creation of a larger size to increase the reliability of cuff seal pressure and a moulded back plate for the cuff. A laryngeal mask airway (LMA) — also known as laryngeal mask — is a medical device that keeps a patient's airway open during anaesthesia or unconsciousness. The laryngeal mask is still widely used today worldwide and a variety of specialised laryngeal masks exist. [Medline], This page was last edited on 15 October 2020, at 09:51. Br. Brodrick P.M., Webster N.R., Nunn J.F. LMA means 'Leave Me Alone.' The laryngeal mask airway. A study of 100 patients during spontaneous breathing. Brain realised the exciting possibility that the laryngeal mask could be applied to head and neck surgery[3] and also observed that "In two patients the anatomy was such as to suggest that endotracheal intubation might have presented at least moderate difficulty. In: The Laryngeal Mask Airway: A Review and Practice Guide. Neither presented difficulty with regard to insertion of the laryngeal mask ". Brain with 5 co-authors published a second paper in anaesthesia describing the use of the laryngeal mask in over 500 patients, adding considerable credence to the laryngeal mask concept. [1], Archie Brain began studying the anatomy and physiology of the upper airway in relation to existing airways. It is a type of supraglottic airway device.

The publication of this trial in 1989 was critical in kickstarting the uptake of the laryngeal mask in the UK". LMA International N.V. A laryngeal mask is composed of an airway tube that connects to an elliptical mask with a cuff which is inserted through the patient's mouth, down the windpipe, and once deployed forms an airtight seal on top the glottis (unlike tracheal tubes which pass through the glottis) allowing a secure airway to be managed by a health care provider. Annual Report 2011, pp.

The silicone prototype was also smooth and deflated into a wafer thin ellipse, however, the silicone mask was unable to retain the desired bowl shape and it was no longer possible to make rapid adjustments to the design. 16–20.

The anaesthesia community had been calling for practice guidelines and in 1992 the ASA commissioned a task force to establish practice guidelines for managing difficult airway situations. They are most commonly used by anaesthetists to channel oxygen or anaesthesia gas to a patient's lungs during surgery and in the pre-hospital setting (for instance by paramedics and emergency medical technicians) for unconscious patients.
