Archie Ian Jeremy Brain (1942 – )

Archie Ian Jeremy Brain (1942 – ) is a British anaesthetist.

Brain is an award winning anaesthetist and is an honorary fellow of the Royal Collage of Anaesthetists. Brain is best known for inventing the Laryngeal Mask Airway (LMATM).

His medical education took place at the Radcliffe Infirmary in Oxford and he completed his clinical studies in St Bartholomew’s Hospital. He obtained a diploma in anesthetics within one year whilst working in Hastings, East Sussex.

From his time working as an anaesthetist he had the idea to attempt to make airway management less traumatic and more physiological. Whilst lecturing at The Royal London Hospital in 1980 he found the time to develop his ideas and the LMA was produced. Brain personally made his LMA prototypes and they were successfully trialled on patients from 1981. The first commercially made silicone model was released in 1988 and within 1 year it was used in more than 500 British hospitals and the LMA continues to be used today.

Medical Eponyms
Laryngeal mask airway (1983)

The laryngeal mask was a new type of airway that could be used as an alternative to the endotracheal tube or the face mask with either spontaneous or positive pressure ventilation.

The Laryngeal mask airway is a surpraglottic airway device that is composed of an airway tube and an elliptical mask with a cuff that connects to the glottis. The cuff could be inflated to create a seal once in place and deflated for easy removal.

Viewed mechanically, tracheal intubation is a procedure in which two tubes, one man-made and the other anatomical, are connected together by inserting one into the other, a cuff being inflated on the inner tube to effect a gas-tight seal. In engineering terms, this solution to the problem of forming a gas-tight junction between two tubes is rather unsatisfactory, since it necessarily involves a degree of constriction at the point of junction unless the outer tube is itself expanded to compensate. Ideally, it is desirable that both tubes are of the same internal diameter at their point of junction, since this has clear advantages in terms of gas flow. This involves connecting them end to end, since the option of expanding the anatomical tube is not practicable.

An examination of postmortem specimens of the adult male and female larynx was made to assess how such a joint might be achieved. It was noted that an airtight seal could be effected against the perimeter of the larynx posteriorly by an elliptical cuff inflated in the hypopharynx. This observation led to the concept of the Laryngeal Mask.

The invention of the LMA was a key contribution to anaesthetics. Prior to Brain’s invention the routine use of a facemask to manage the airway was not a hands-free technique, despite the development of various harnesses. This made adequate record-keeping difficult during anesthesia and made this mask a revolutionary change in anaesthetics.  The masks are still used today in hospital and pre-hospital settings.


Dr Brain discusses how he became interested in anaesthesia, the invention of the LMA, the rejection of his invention and its ultimate success.
