This is a simple and ready plan of treatment,which has been successful in the authors hands, and Electro-Therapeutics 299 which, if static electricity can be obtained, is certainlyworth a trial. In more obstinate cases a bougie electrode (Fig. 131)can be introduced per rectum, the other pole being onthe abdomen, and a faradic current passed. In cases ofobstruction, where the bowel is dilated, and the muscularfibre paretic, galvanic currents are the most serviceable.It was stated in the chapter on physiology that stimuli ofsome duration were the best for involuntary muscles ;this is still more the case when these muscles are partiallyparalyzed. A faradic current may, under these circum-stances, have little or no effect; while an interruptedgalvanic current, especially if allowed to flow for a shorttime between the interruptions, and if occasionally re-

The effectwill be enhanced if one pole be introduced per rectum, butthe difficulty has always been to avoid electrolysis anddestruction of the wall of the bowel at the point of applica-tion of the electrode. Boudet solved this problem byincreasing the area of the intestinal electrode with warmsalt water. A catheter rectal electrode, insulated except at its tip,is used; this is passed up the bowel as far as it will go,and is connected with the positive pole ; the negativepole, of large size, rests upon the abdomen. When allis ready, about two pints of warm slightly-salted waterare allowed to flow through the catheter into the bowel,and the current is turned on, and raised to about 30 m.a.In five minutes time it is brought back to zero, reversed. 300 A Manual of Practical Medical Electricity and then increased again.
