In default of sulphate of copper, then sulphate of zinc or mustard.
Give 1⁄2-drachm doses of turpentine, floating on water or on mucilage, every half hour. Inhalations of turpentine vapour, much diluted, are also of service. The American and German turpentines are said to be of no avail. Probably the turpentine will freely purge the patient; but, if not, the bowels should be opened by a suitable purgative, such, for instance, as magnesic sulphate.
Physostigmine.—See [Calabar Bean].
Use stomach-pump or tube, or empty stomach by usual emetics, e.g., mustard, zinc sulphate, or apomorphine, subcutaneously.
Chloral, in doses of from 10 to 20 grains, may be given every half hour to allay or prevent tetanus, the effects being, of course, watched. For the same purpose bromide of potassium has been recommended. In severe cases, it may be combined with choral, 1 drachm of the bromide with 20 grains of chloral.
The best treatment is a subcutaneous dose of atropine (say 1-60th of a grain) or tincture of belladonna by the mouth in 20-minim doses, to be repeated every twenty minutes until the pupils dilate.
