Phenol treatment for Tetanus, which has given very good results and I would recommend one drachm in three ounces of water, injected hypodermically in the region of neck and shoulder every two or three hours until twelve injections were given and less frequently thereafter.
Doses.—Of the phenol: Horses and cattle, 10 to 40 grs.; sheep and pigs, 5 to 10 grs.; dogs, 1⁄2 to 1 gr., well diluted.
Toxicology.—Dogs and cats are especially susceptible to the action of carbolic acid, therefore great care must be exercised when washing, especially cats, with any preparation containing carbolic acid. Disinfecting and deodorizing cat’s quarters with any preparation containing carbolic acid makes them sick.
Antidote.—Sulphates of soda or magnesia. Atropine sulphate hypodermically is a very valuable antidote. Alcohol and vinegar have been used with good results, both internally and externally.
ACIDUM SALICYLICUM—SALICYLIC ACID
An organic acid, existing naturally in combination in various plants, but largely prepared synthetically from carbolic acid.
Derivation.—Made by passing carbonic dioxide through sodium carbolate at a temperature of 428° F. (220° C.). 2 NaC6H5O (sodium carbolate) + CO2 = Na2C7H4O3 (sodium salicylate) + C6H6O (phenol). Sodium salicylate is treated with hydrochloric acid when salicylic acid is precipitated.
Properties.—Light, fine, white, needle-shaped crystals, odorless, having a sweetish, afterwards acrid taste; permanent in air. Soluble in alcohol, ether and hot water; borax increases its solubility.
Dose.—Horses, 2 to 6 drs.; cattle, 1⁄2 to 1 oz.; sheep, 1 to 2 drs.; pigs, 30 to 40 grs.; dogs, 5 to 20 grs.; should be given well diluted; large doses are recommended for fevers, but smaller doses more often repeated in rheumatism.
