There are two periods in the course of a croupous pneumonia in which
blood-letting may be of service; first, in the early stage for the relief
of pain and dyspnea, and second, in an advanced stage where there is engorgement
of the right heart, also associated with intense dyspnea and general venous
No remedy is so efficient for the first object as blood-letting by the
application of cut cups. Poultices, counter-irritation by the various measures
commonly employed and even full doses of morphin hypodermically, are comparatively
valueless as compared with wet cupping. Full doses of morphin produce temporary
relief, but it passes away as soon as the effect of the drug wears off. No
one who has not seen the happy result of such a bleeding can realize it. Venesection
at the arm is less efficient, although it, too, relieves engorgement and diminishes
pain and dyspnea. By no means every case of pneumonia, however, demands such
treatment, and it is especially the cases associated with pleurisy—pleuropneumonia—in
which it is indicated and is of such signal service.
