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.

[citation needed], Following the realisation that a new material was needed, Brain looked at a number of options; polyvinyl chloride was too rigid and synthetic foam did not lend itself to re-use. Circulation. A laryngeal mask has an airway tube that connects to an elliptical mask with a cuff. By 1992, the laryngeal mask was approved for sale and being sold in Australia, New Zealand, South Korea, Hong Kong, Taiwan, Malaysia, India and the United States. Finally, Dr Brain used the device in a dental extraction patient, he realised that because the space in and around the glottis was filled by the mask, the need for packing was much reduced and more impressively the larynx was completely protected from surgical debris. 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.

[1], Archie Brain began studying the anatomy and physiology of the upper airway in relation to existing airways. Neither presented difficulty with regard to insertion of the laryngeal mask ". [2], The first study of a laryngeal mask in 23 patients was conducted at London Hospital in 1982. The publication of this trial in 1989 was critical in kickstarting the uptake of the laryngeal mask in the UK". Existing airway devices clearly failed to form this junction; the face-mask sealed against the face, and the endotracheal tube penetrated too far so that the junction was created within the trachea, instead of at its beginning. Brain AIJ, Denman WT, Goudsouzian NG (1999). Brain concluded that current techniques for connecting artificial airways to the patient were not ideal, reasoning that if the respiratory tree is seen as a tube ending at the glottis and the objective is to connect this tube to an artificial airway, the most logical solution was to create a direct end-to-end junction. It is a type of supraglottic airway device. Brain published a case series in Anaesthesia in 1985 describing the management of 3 difficult airway patients, illustrating the use of the laryngeal mask for airway rescue. 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. 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.

The cuff can either be of the inflating type (achieved after insertion using a syringe of air), or self-sealing. (1983)The Laryngeal Mask – A new concept in airway management. 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. 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. Nonanesthetic uses. Once inserted correctly (and the cuff inflated where relevant) the mask conforms to the anatomy with the bowl of the mask facing the space between the vocal cords. (1989). 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. 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. Guidelines for cardiopulmonary resuscitation and emergency cardiovascular care. The laryngeal mask had now been widely accepted as a form of airway management.[7]. [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. 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. The laryngeal mask is still widely used today worldwide and a variety of specialised laryngeal masks exist.

The LMA Classic was launched in the UK and the British anaesthesia community were quick to realise the potential benefits of the laryngeal mask.
