Treatment.—Make haste when high choke is present. Perform tracheotomy to relieve the breathing; insert the balling-iron, or, with a hook extemporized out of any wire, endeavor to remove the substance from the throat. If the choking body is too firmly lodged to be thus removed, sulphuric ether must be inhaled to relax the spasm. The ether not succeeding, an egg is probably impacted. Destroy its integrity with a darning-needle carefully inserted through the skin; then break the shell by outward pressure. Low choke is seldom fatal before the expiration of three days. Give a quarter of a pint of oil every hour; in the intermediate half hours give sulphuric ether, two ounces; laudanum, two ounces; water, half a pint; and use the probang after every dose of the last medicine. Should these be returned, cause chloroform to be inhaled; then insert the probang, and, by steady pressure, drive the substance forward.
Subsequent to the removal of impactment feed with caution.
CHRONIC DYSENTERY.
Cause.—Not well understood; generally attacks old horses belonging to penurious masters.
Symptoms.—Purging without excitement, always upon drinking cold water; violent straining; belly enlarges; flesh wastes; bones protrude; skin hide-bound; membranes pallid; weakness; perspiration; standing in one place for hours. At last the eyes assume a sleepy, pathetic expression; the head is slowly turned toward the flanks; remains fixed for some minutes; the horse only moves when the bowels are about to act; colic; death.
Treatment.—Give, thrice daily, crude opium, half an ounce; liquor potassæ, one ounce; chalk, one ounce; tincture of all-spice, one ounce; alum, half an ounce; ale, one quart. Should the horse belong to a generous master, give one of the following drinks thrice daily, upon the symptoms being confirmed: Sulphuric ether, one ounce; laudanum, three ounces; liquor potassæ, half an ounce; powdered chalk, one ounce; tincture of catechu, one ounce; cold linseed tea, one pint. Or, chloroform, half an ounce; extract of belladonna, half a drachm; carbonate of ammonia, one drachm; powdered camphor, half a drachm; tincture of oak-bark, one ounce; cold linseed tea, one pint. Feed lightly; dress frequently; give a good bed and a roomy lodging.
CHRONIC GASTRITIS.
Symptoms.—Irregularity of bowels and appetite; pallid membranes; mouth cold; a dry cough; tainted breath; sunken eye; catching respiration; pendulous belly; ragged coat, and emaciation. Sweating on the slightest exertion; eating wood-work or bricks and mortar.
Treatment.—Do not purge; administer bitters, sedatives, and alkalies. Give powdered nux vomica, one scruple; carbonate of potash, one drachm; extract of belladonna, half a drachm; extract of gentian and powdered quassia, of each a sufficiency. Or give strychnia, half a grain; bicarbonate of ammonia, one drachm; extract of belladonna, half a drachm; sulphate of zinc, half a drachm; extract of gentian and powdered quassia, of each a sufficiency. Give one ball night and morning; when these balls seem to have lost their power, give half an ounce each of liquor arsenicalis and tincture of ipecacuanha, with one ounce of muriated tincture of iron and laudanum, in a pint of water; damp the food; sprinkle magnesia on it. As the strength improves, give sulphuric ether, one ounce; water, one pint, daily. Ultimately change that for a quart of ale or stout daily.
