  8. The chief symptoms of pneumonia are: - pyrexia, accompanied by pain, sometimes obtuse, at others pungent,-in some part of the thorax; pulse more or less quick and hard, according to the violence and extent of the local disorder; pain, aggravated by the cough, which, with dyspnoea, exists throughout the disease. At first, the expectoration is difficult and painful; but, in the course of a few days, it becomes free, and the oppression of breathing is mitigated. When the inflammation, instead of going off by resolution, passes on to suppuration, rigors are experienced; the respiration becomes more oppressed, but less painful, and a sense of weight is felt in one of the pleurae. Pneumonia may, also, terminate by gangrene-but this rarely happens,- by induration and by hepatization. Physical Signs. First Stage, (F.) Engouement. Diminution of the sound is generally observed over the affected part on percussion; auscultation exhibits an equal, dry, crepitating rale, which is best heard at the close of a deep inspiration, and on coughing. The respiratory murmur is intermingled with the crepitant rale, or it may be absent. In the neighbourhood of the affected parts it is natural or puerile. The voice and cough are rather more resonant than usual. Second Stage, (F.) Hepatisation rouge. When hepatization has occurred, the motion of the affected side is impeded, and immediately above the sternum and in the corresponding triangular space on either side, there is often an evident depression. Percussion is dull over the affected part in every position of the patient. On auscultation, the crepitation is found to be replaced by bronchial respiration. The respiratory murmur is louder in the other portions of the lung, the voice and cough are more resonant, and the heart's action is more distinct. Third Stage, (F.) Hepatisation grise. When suppuration supervenes, the same signs persist; but usually the voice and cough are less resonant, and a coarse, mucous rale is heard. When gangrenous or suppurative cavities are formed, they present the ordinary signs. The prognosis must be guarded. It is not a disease which we can always subdue. Great extent of inflammation; very considerable oppression; orthopnoea, and difficult expectoration are unfavourable symptoms. The most active treatment is of course necessary. General bleeding forms the sheet anchor,-employed so as to make a decided impression on the system, and repeated, if necessary; local blood-letting; nauseating doses of antimonials; purgatives; and when the violence of the inflammation has been got under, - counter-irritants, Ac. Chronic pneumonia sometimes succeeds the acute, and, at others, occurs accidentally. It must be managed on general principles. Small bleedings, especially locally; and counter-irritants of all kinds are indicated. Medical Lexicon. A Dictionary of Medical Science
  9. [Greek] Inflammation of the lung. Lobar p. (Croupous p., pneumonic fever, lung fever), an acute specific fever characterized by inflammation and consolidation of one or both lungs, one or more lobes of which are usually involved. Due usually to Micrococcus lanceolatus, less often to Bacillus pneumoniae (which often produces a severe type of disease) and Bacillus pneumosepticus. It begins with a chill, followed by a sudden rise of temperature, marked febrile symptoms, great dyspnoea and rapidity of respiration, pain in the side, and cough with tenacious blood-stained expectoration. After lasting a week the symptoms suddenly abate (crisis) and convalescence begins. The lung is at first intensely congested and oedematous (stage of engorgement), afterward pefectly solid and red, through accumulation of blood-cells and a fibrinous exudate in the alveoli (stage of red hepatization), and still later becomes gray (stage of gray hepatization) owing to the degeneration of the exuded matters, which are then gradually absorbed when the lung returns to the normal state. P. usually begins in the lower lobe, but may especially in old people) begin at the apex Apical p.) and, in bed-ridden people eneebled by disease, often occurs from hypos-tasis (Hypostatic p.) in the most dependent part of the lung. P. may also be induced by the entrance of food or similar matter into the bronchi (Aspiration p., Deglutition pp.), especially after section of the vague ( Vagus-p.). Catarrhal p. (Lobular p., Broncho-pneumonia), a form which begins as a capillary bronchitis with occlusion of the bronchioles by exudate, and which afterward extends to the alveoli supplied by these bronchioles. Patches of consolidation affecting single lobules or sometimes only discrete groups of vesicles (Disseminated p., Vesicular p.) are thus formed. By extension of the process large areas of tissue may be involved. Lobular p. is a more chronic disease than lobar p., and occurs especially in children. Interstitial p. (Fibrous p., Fibroid phthisis, Cirrhosis of the lung), a very chronic form in which there is a gradual increase of the interstitial tissue and a corresponding atrophy of the true lung-tissue. The name is particularly applied to a sort of chronic lobar p. (also called Parenchymatous, Desquamative, or Primary indurative p.) which invades successively different parts of the lungs, and is attended with induration of the fibrinous exudate, interstitial proliferation, and proliferation and fatty degeneration of the pulmonary epithelium. P. alba, diffuse syphilitic infiltration of the lung in the new-born, in which the lung is white and completely airless. Puruent or Suppurative p. may occur as a sequela of ordinary p. or by metastasis (Metastatic p.) in pytemia, and is marked either by the formation of abscesses in the lungs or by purulent infiltrates following the course of the lymph-vessels in the interlobular tissue. A special variety of the second form is P. dissecans, in which the lobules are pushed apart by purulent infiltrates. Cheesy p., inflammation, usually, chronic, attended with cheesy degeneration of the inflammatory prducts; an accompaniment usually of tuberculous processes and associated with destrution of the lung, the formation of caverns, and hectic fever. TREATMENT OF ACUTE P.: in earliest stages of sthenic cases, antiphlogistics (aconite, tartar emetic, veratrum viride), bloodletting, general and local, counter-irritation over chest; creosotal; morphine cautiously administered for pain ;careful attention to nourishment; stimulants (alcohol, ammonia, digitalis, styehnine, belladonna) in asthenic cases; stimulating expectorants in stage of resolution. In CHRONIC P., careful attention to nutrition; removal of causes of bronchial irritation; treatment of concomitant bronchitis; counter-irritation. na
