=INHALA'TION.= _Syn._ Inhalatio, L. In _medicine_, the drawing in or inspiring of vapour with the breath. Inhalations (INHALATIONES) are vapours or gases imbibed for the purpose of medicating the mucous membrane of the air-passages. The substances that are to furnish the vapours or fumes are put into a vessel called an 'inhaler' (see INHALER), which may be simply a small covered pot or mug of metal or glass, furnished with a short flexible tube, terminating in a small mouth-piece. In many cases even this simple apparatus may be dispensed with, and the fumes inhaled by holding the head over a vessel containing a little of the substance furnishing them; or, as with chloroform, a little may be dropped on a handkerchief or napkin, which is then held to the nose.
The following are the principal substances that are employed for inhalations at the present day:--
1. Carbonic acid gas and nitrous oxide; occasionally used in phthisis, by means of a bladder and mouth-piece.
2. Chlorine gas; exhibited by adding 5 or 6 drops of aqueous chlorine to the water (tepid) of the inhaler, which should be, in this case, of glass; employed in France for phthisis, but seldom used in England.
3. Chloroform; as an anaesthetic.
4. Vapour of iodine, administered in the same way as chlorine; occasionally used in phthisis.
5. Oxygen and hydrogen gases, either alone or diluted with air; employed in asthma and phthisis, by means of a bladder and mouth-piece.
6. Tar vapour, obtained by heating tar, mixed with a little carbonate of potash, over a spirit lamp, occasionally employed in bronchitis, and recommended by Sir A. Crighton in phthisis, but appears of little value in the latter.
7. Steam of hot water; in bronchitis, and to allay the cough in phthisis; small quantities of the seeds of henbane, opium, poppy-heads, &c., are frequently added to produce an anodyne effect. See CIGARS (in pharmacy), DISINFECTANTS, FUMIGATION, VAPOURS, &c.
=INJEC'TION.= _Syn._ INJECTIO, L. In _medicine_, any liquid medicine thrown into a cavity of the body by means of a syringe or an elastic bag.
