Electrolysis has been successfully employed in several cases of aneurism. Where pressure and ligature admit of application, it is hardly necessary to say that the preference should be given to them; but many internal aneurisms, and especially aortic aneurisms, cannot be thus treated, and in such cases the question of electro-puncture should be carefully considered, and, when called for, it should not be too long delayed. Two fine, sharp, and carefully insulated needles, one connected with each pole, should be introduced into the aneurismal sac, and the current allowed to pass for from half an hour to an hour, the needles carefully withdrawn, and their punctures covered with a bit of lint soaked in collodion or styptic colloid. Authorities are divided as to the kinds of aneurism calculated for electro-puncture, but there is no doubt than an aneurism pressing on the parietes, but not having actually perforated them, is the best adapted for this treatment, and that it is contra-indicated where the sac is of large size, or where large trunks issue from it. [19] The following is an illustrative case:-- A lady, forty-one years of age, had suffered from right hemiplegia for eighteen months, and described her condition as having remained without improvement for the past six months. She had recovered sufficiently to walk with the aid of a stick, but the movements of the arm were very weak, especially those of the deltoid, extensors of the fingers, and individual muscles of the hand. Faradic contractility was somewhat lowered, but there was no rigidity. The muscles were carefully Faradized with a current just sufficiently strong to produce their contraction. The entire application occupied about fifteen minutes, and was made once daily. After a fortnight’s electrization she was able to raise the arm to a right angle with the body, and _to use the hand to feed herself_, neither of which had she been able to do before treatment. [20] The following is an extract from Dr. Sturge’s Report of the results of treatment at the National Hospital for the Paralyzed and Epileptic:-- “In the division of Muscular Atrophies some striking cases have occurred, and in all of these the improvement is mainly due to the electrical treatment prescribed. “A patient, with atrophy of some of the muscles of both arms of six months’ standing, which incapacitated her from dressing herself or cutting her food, or doing much household work, was discharged at the end of three and a half months, able to feed and dress herself, sew, and perform almost any domestic duty. “Another woman, with atrophy of the muscles of the forearm of several years’ standing, and who was similarly incapacitated from almost all use of the hands, went out, after a month’s treatment, able to dress and feed herself, and to perform many actions that were before impossible for her.
