Injections into Lung Cavities.
Much has been written at different times on the injection of substances directly into the lung cavity in tuberculosis. A recent writer has had good results in the control of the hemorrhage of tuberculosis by the injection of five grains of tannic acid dissolved in water, directly into the cavity without regard to the fact that the cavity is filled with blood. The results were satisfactory both in controlling the hemorrhage and in the exercise of a general benefit. In using this injection the writer thinks that it must be determined that the hemorrhage is otherwise uncontrollable. He must locate the cavity definitely and avoid infection. The general condition of the patient, the above facts being determined, need not be taken into consideration.
