Produktbeschreibung
Excerpt from Twentieth Century Practice, Vol. 16 of 20: An International Encyclopedia of Modern Medical Science Synonyms. - Croupous pneumonia, Fibrinous pneumonia, Pneumonitis, Lung Fever. The lung differs from all other structures in having two separate circulations: the nutritive, supplied from the left side of the heart through the bronchial arteries, and the functional, supplied from the right side of the heart through the pulmonary artery. This double circulation underlies all the phenomena of pneumonia, and must be recognized in any definition of the disease, as without it the disease itself could not exist. Definition. - Lobar pneumonia is an acute disease in which a specific parasite invades the air cells of one or more pulmonary lobes, where it grows in a fibrinous medium exuded from the functional capillaries, and generates a toxin that infects the system at large. The local process causes consolidation of the affected area by filling the air cells with the effused material, which, material is afterwards removed, leaving the structure of the lung intact. The general infection is marked by fever, which, in a typical case, begins with a chill, and after a duration of from four to nine days ends abruptly by crisis. In most cases a local dry pleuritis is excited, the phenomena of which are added to those of the pneumonia proper. Death may take place from the virulence of the infection, from loss of respiratory surface, from exhaustion of the right heart, from consecutive asthenia, from complications, or from a combination of two or more of these causes. Symptoms. A brief sketch of the principal clinical features of the disease will be useful as affording a preliminary view of the field to be examined. The attack may be preceded by prodromes to be hereafter described, but as a rule the first complaint of the patient is of a pain in the chest, usually in the mammary region. This is often very severe, and by restricting the movements of the ribs renders the respiration superficial and rapid.
