I know that it will be objected here that the consumption is sometimes produced by scrophula, and that this creates an essential difference between it and pneumony. I formerly admitted scrophula to be one of the remote causes of the consumption; but this does not invalidate the parallel which has been given of the two diseases. The phenomena produced in the lungs are the same as to their nature, whether they be produced by the remote cause of scrophula, or by the sudden action of cold and heat upon them.
No more happens in the cases of acute and chronic pneumony, than what happens in dysentery and rheumatism. These two last diseases are for the most part so acute, as to confine the patient to his bed or his room, yet we often meet with both of them in patients who go about their ordinary business, and, in some instances, carry their diseases with them for two or three years.
The parallel which has been drawn between the pneumony and consumption, will enable us to understand the reason why the latter disease terminates in such different periods of time. The less it partakes of pneumony, the longer it continues, and vice versa. What is commonly called in this country a galloping consumption, is a disease compounded of different degrees of consumption and pneumony. It terminates frequently in two or three months, and without many of the symptoms which usually attend the last stage of pulmonary consumption. But there are cases in which patients in a consumption are suddenly snatched away by an attack of pneumony. I have met with one case only, in which, contrary to my expectation, the patient mended after an attack of an acute inflammation of the lungs, so as to live two years afterwards.
It would seem from these facts, as if nature had preferred a certain gradation in diseases, as well as in other parts of her works. There is scarcely a disease in which there is not a certain number of grades, which mark the distance between health and the lowest specific deviation from it. Each of these grades has received different names, and has been considered as a distinct disease, but more accurate surveys of the animal economy have taught us, that they frequently depend upon the same original causes, and that they are only greater or less degrees of the same disease.
I shall now proceed to say a few words upon the cure of the different states of pulmonary consumption. The remedies for this purpose are of two kinds, viz. PALLIATIVE and RADICAL. I shall first mention the palliative remedies which belong to each state, and then mention those which are alike proper in them all. The palliative remedies for the
I. Or INFLAMMATORY STATE, are
I. Blood-letting. It may seem strange to recommend this debilitating remedy in a disease brought on by debility. Were it proper in this place, I could prove that there is no disease in which bleeding is prescribed, which is not induced by predisposing debility, in common with the pulmonary consumption. I shall only remark here, that in consequence of the exciting cause acting upon the system (rendered extremely excitable by debility) such a morbid and excessive excitement is produced in the arteries, as to render a diminution of the stimulus of the blood absolutely necessary to reduce it. I have used this remedy with great success, in every case of consumption attended by a hard pulse, or a pulse rendered weak by a laborious transmission of the blood through the lungs. In the months of February and March, in the year 1781, I bled a Methodist minister, who was affected by this state of consumption, fifteen times in the course of six weeks. The quantity of blood drawn at each bleeding was never less than eight ounces, and it was at all times covered with an inflammatory crust. By the addition of country air, and moderate exercise, to this copious evacuation, in the ensuing spring he recovered his health so perfectly, as to discharge all the duties of his profession for many years, nor was he ever afflicted afterwards with a disease in his breast. I have, in another instance, bled a citizen of Philadelphia eight times in two weeks, in this state of consumption, and with the happiest effects. The blood drawn at each bleeding was always sizy, and never less in quantity than ten ounces. Mr. Tracey of Connecticut informed me, in the spring of 1802, that he had been bled eighty-five times in six months, by order of his physician, Dr. Sheldon, in the inflammatory state of this disease. He ascribed his recovery chiefly to this frequent use of the lancet. To these cases I might add many others of consumptive persons who have been perfectly cured by frequent, and of many others whose lives have been prolonged by occasional bleedings. But I am sorry to add, that I could relate many more cases of consumptive patients, who have died martyrs to their prejudices against the use of this invaluable remedy. A common objection to it is, that it has been used without success in this disease. When this has been the case, I suspect that it has been used in one of the other two states of pulmonary consumption which have been mentioned, for it has unfortunately been too fashionable among physicians to prescribe the same remedies in every stage and form of the same disease, and this I take to be the reason why the same medicines, which, in the hands of some physicians, are either inert or instruments of mischief, are, in the hands of others, used with more or less success in every case in which they are prescribed. Another objection to bleeding in the inflammatory state of consumption, is derived from the apparent and even sensible weakness of the patient. The men who urge this objection, do not hesitate to take from sixty to a hundred ounces of blood from a patient in a pneumony, in the course of five or six days, without considering that the debility in the latter case is such as to confine a patient to his bed, while, in the former case, the patient's strength is such as to enable him to walk about his house, and even to attend to his ordinary business. The difference between the debility in the two diseases, consists in its being acute in the one, and chronic in the other. It is true, the preternatural or convulsive excitement of the arteries is somewhat greater in the pneumony, than in the inflammatory consumption; but the plethora, on which the necessity of bleeding is partly founded, is certainly greater in the inflammatory consumption than in pneumony. This is evident from women, and even nurses, discharging from four to six ounces of menstrual blood every month, while they are labouring with the most inflammatory symptoms of the disease; nor is it to be wondered at, since the appetite is frequently unimpaired, and the generation of blood continues to be the same as in perfect health.
Dr. Cullen recommends the use of bleeding in consumptions, in order to lessen the inflammation of the ulcers in the lungs, and thereby to dispose them to heal. From the testimonies of the relief which bleeding affords in external ulcers and tumours accompanied by inflammation, I am disposed to expect the same benefit from it in inflamed ulcers and tumours in the lungs: whether, therefore, we adopt Dr. Cullen's theory of consumption, and treat it as a local disease, or assent to the one which I have delivered, repeated bleedings appear to be equally necessary and useful.
I have seen two cases of inflammatory consumption, attended by a hæmorrhage of a quart of blood from the lungs. I agreed at first with the friends of these patients in expecting a rapid termination of their disease in death, but to the joy and surprise of all connected with them, they both recovered. I ascribed their recovery wholly to the inflammatory action of their systems being suddenly reduced by a spontaneous discharge of blood. These facts, I hope, will serve to establish the usefulness of blood-letting in the inflammatory state of consumption, with those physicians who are yet disposed to trust more to the fortuitous operations of nature, than to the decisions of reason and experience.
I have always found this remedy to be more necessary in the winter and first spring months, than at any other season. We obtain by means of repeated bleedings, such a mitigation of all the symptoms as enables the patient to use exercise with advantage as soon as the weather becomes so dry and settled, as to admit of his going abroad every day.
