Profuse evacuations, of any kind, may be the cause of Secondary Phthisis. Hæmorrhages from the Nose, Lungs, Stomach, Kidneys and wounds are all mentioned by Morton, as having induced Pulmonary disease. Mr. Hey, in his work on Surgery, observes, that he has seen a great many cases of pulmonary Consumption, the consequence of debility, induced by violent hæmorrhages, and in persons who had no apparent tendency to Consumption. In the same manner, loss of blood from Hæmorrhoids and in Menorrhagia, may act as causes. Debilitating evacuations, by means of Diarrhœa, Diabetes, Salivation, and Sweating, have had the same effect. But the most frequent causes of this class are, immoderate discharges by fluor albus, and too long suckling by delicate woman of robust children. They are particularly mentioned by Morton and Fothergill, and have been adverted to by most authors, who have written since. Chronic Catarrh, terminating in Phthisis, may be ranked also in this class. The profuse and long continued discharge from the membrane lining the trachea and bronchiæ, is the debilitating agent in that case. Long continued Fevers, and particularly Intermittent fevers, not unfrequently leave behind them, a state of debility, sufficient to induce Consumption. In the New-York Hospital, frequent instances occur of Consumption induced by intemperance in the use of ardent spirits. This habit destroys the tone of the stomach, which becomes primarily affected, and in consequence the whole system becomes debilitated, terminating in disease of the Lungs. Secondary Consumption has also been induced by some other preceeding diseases, such as Scurvy and Syphilis, and requires the attention of the Physician, to the primary disease rather than to the affection of the Lungs. In the treatment of Pulmonary Consumption, arising from any of these or analogous causes, our attention is first called to the removal of the primary source of the disease. If it be Chlorosis, remedies, calculated to cure that malady, must be prescribed. If profuse evacuations are the cause, all the means in our power, must be employed in restraining those evacuations. If the disease has been induced by the long continued suckling of a vigorous child, by a delicate mother, another nurse must be provided, or the child must be weaned. If Scurvy or Syphilis have produced it, the proper remedies for those disorders must be employed.
