Very marked absorbent or resolvent effects are also exerted by the Voltaic current, and are probably chiefly due to its powerful chemical action, for a current of great strength will dissolve or destroy any animal tissue whatever. One application of this chemical action is found in the electrolysis of tumours; another in the coagulation of blood in aneurisms;[18] and a third in the removal or absorption of gouty and rheumatic deposits. |Rheumatic Gout.| In Rheumatic Gout, Dr. Poore has recorded a very successful result from the use of localized galvanization. The disease had existed for three months, but the severity of the pain had much diminished, excepting towards evening, when exacerbations occurred. The wrist was considerably swollen, and absolutely stiff, the hand pronated and could not be supinated, and the hand and fingers were immensely swollen, so as completely to obscure their anatomy, while the fingers were extended, stiff, pale, and cold, and the nutrition of the entire limb impaired. The whole limb, and especially the hand, was thoroughly sponged with the negative pole, the positive being held in the patient’s other hand. After the third application the swelling rapidly subsided, and in about a fortnight the hand, although still stiff, had resumed its natural aspect. The muscles were then faradized and shampooed.
Rheumatic Arthritis.
Rheumatic arthritis with nodosities is best treated by passing as strong a Voltaic current as the patient will submit to through each swollen joint for a few minutes, the direction of the current being frequently changed by the movement of the commutator of the poles.
Muscular Rheumatism.
The pains of muscular rheumatism are almost invariably removed or mitigated by cutaneous faradization, and so rapidly as in many cases to appear marvellous. In cases that had resisted all other treatment, an instantaneous cure has resulted, and sufferers whose pain has for a long time obliged them to keep the arm immovable have been able directly after the faradization to execute any movement with ease. With these rheumatic patients it is especially of importance that the current should be strictly limited to the skin, carefully dried and powdered, and should produce no muscular contraction, or the suffering will be aggravated instead of relieved. Begin with a current readily bearable on your own hand, and increase afterwards. The above remarks are applicable to all varieties of muscular rheumatism, but not to arthritic disease.
General effects of Electrization.
So much for the general effects of electricity. All the structures of the body respond to its application; the muscles and motor nerves, as we have seen, by contraction; the nerves of common sensation by a burning or pricking; and of the nerves of special sense; the retina by a flash of light; the auditory nerve by a sound; the olfactory nerve by a peculiar smell; and the gustatory by a metallic taste, differing at the two poles. The action of the Voltaic current upon the brain is exceedingly powerful, and the greatest care must be exercised when it is applied to any part of the head or face. Not more than two or three cells should be commenced with. Its effect should be noted, and any increase should be made gradually. With a very moderate current giddiness is produced, and upon the sudden application of a sufficiently powerful one the patient falls down as if struck by a blow.
General Debility.
All, or some of the more or less generalized applications, such as Beard and Rockwell’s generalized electrization, the common Faradaic and Voltaic Baths, or Radcliffe’s Charge, are of occasional benefit in conditions of general debility, and where general stimulation of the nervous centres is indicated. The electric bath is an elegant and pleasant mode of administering electricity, but it is less generally beneficial (except in certain gouty or rheumatic cases) than localized applications of electricity. The statement that metallic poisons can be eliminated from the body by its agency has not yet been established.
Paralysis.
