The galvano-cautery can only be used in the nasal chamber in patients who are earnestly seeking relief and are willing to assist the physician in all his efforts. With the tractable, intelligent subject it can with proper care be limited exactly to the spot intended. It is scarcely necessary to observe that any erratic or unexpected motion of the head will sear unaffected and sensitive surfaces. The interior of the vestibule is perhaps the most sensitive of these, and should always be protected by the use of the nasal speculum. No additional protection is needed, though in the judgment of others, among whom may be mentioned E. Shurly of Detroit, Michigan, an ivory shield passed in the nose parallel to the electrode is a necessary safeguard. The pain of the application is generally slight, and can be in part annulled by a previous application of a 4 per cent. solution of cocaine. Some annoyance is acknowledged on the following day from the pressure of the eschar. Traumatic congestion of the entire mucous surface of the corresponding chamber is at the same time detected, and is usually sufficiently decided to produce some of the effects of acute coryza. This condition will spontaneously terminate in from thirty-six to forty-eight hours. The most annoying features {45} following an application of the galvano-cautery which has been too freely made do not belong to the group just indicated, but rather to reflex disturbances. Pains are occasionally excited in the teeth, in the temple, eye, nape of the neck, and the middle ear. On one occasion in the writer's experience a unilateral reflex excitation of the entire opposite side of the body occurred, and a prickling sensation, followed by numbness, ensued, which lasted for twenty-four hours. Very rarely a congestion of the pharynx, of the larynx, and the larger bronchial tubes ensues, which can scarcely be directly attributable to the application, yet it has followed in a sufficient number of cases to lead me to believe that the two are in some remote way associated. Perhaps such a condition is analogous to the slight irritation of the respiratory tract following excision of the tonsil. Careful use of the galvano-cautery will obviate the conditions above described. They are important to remember as serving as limitations to the use of this valuable agent.
