Ayre T-piece (1937)
The anaesthesia employed for hare-lip and cleft palate operations at the Babies’ Hospital, Newcastle upon Tyne, may be divided into two phases-the nitrous oxide-oxygen phase and the oxygen-ether phase…After prolonged trial, we found that, while nitrous-oxide-oxygen anasthesia afforded excellent results in adult patients, certain grave disadvantages presented themselves when the same anesthetic was administered to infants…as a result of anoxaemia and excessive re-breathing, the condition of many babies showed marked deterioration within a short space of time.
In an endeavour to remedy the above distressing state of affairs (and spurred on by the caustic criticism of a candid surgeon!), the writer sought to devise a method by which the endotracheal technique could still be utilized without the drawbacks associated with nitrous oxide and excessive re-breathing.
..the apparatus consists of a T-piece which is connected by a short piece of rubber tubing and a Magill angle-piece to a wide-bore Magill rubber catheter previously inserted into the trachea. Through one limb of the T-piece oxygen and ether vapour is delivered from a Boyle or other continuous-flow apparatus. The other limb remains open to the outside airAyre 1937
In 1950 Jackson Rees added an open-ended bag to the expiratory limb that facilitated manual controlled ventilation. Subsequently many further modifications and alternate designs were produced, leading Ayre to reach out to the journal…
To the Editor, ‘Anaesthesia’, I was naturally interested to observe in the January issue of ‘Anaesthesia’ yet another modification of the T-piece, which by now must surely have as many variations as the well-known manufacturer of canned soup and baked beans.Ayre 1967
