-
[ Greek] The condition produced by effusion of watery liquid from the blood( Venous Oe.) or lymph-vessels( Lymphatic Oe.) into the connective tissue. Oe. is characterized by a more or less tense swelling which pits on pressure. In lymphatic Oe. the exuded fluid is rich in leucocytes. Oe. is the regular concomitant of inflammation of connective tissue( Inflammatory Oe., Oe. calidum), in which case it is associated with pain and redness; and it also occurs as a result of active or passive congestion or a watery state of the blood, in which case pain and usually redness are absent( Non-inflammatory Oe., Oe. frigidum). A variety of non-inflammatory Oe. ( Acute non-inflammatory Oe., Acute circumscribed Oe., Oe. cutis) is Angioneurotic Oe. ( see Angioneurotic). Collateral Oe., Oe. of one organ( e. g., one lung) from over-action or engorgement due to disease of its fellow. Oe. may cause serious symptoms from the pressure produced by the swelling or from the occlusion of vessels or other natural passages which it causes; as in Oe. of the glottis, when the swelling of the submucous tissue of the larynx due to Oe. may cause suffocation. Treatment of Oe.: reduction by bandaging, multiple puncture, and drainage with a cannula. Malignant Oe., see Malignant. Oe. neonatorum, an affection, usually fatal, of new-born children, marked by hard spreading Oe. with cold livid skin. Rheumatismal Oe., see Rheumatismal. Solid Oe., myxoedema.

It is improper to employ the caustic when the ulcer is too large to admit of the formation of a complete eschar; or when it is so situated as to render it impossible that the eschar should remain undisturbed, as between the toes, unless, indeed, the patient be confined to his bed;- or in cases attended by much inflammation, or by much oedema. – An Essay on the Application of the Lunar Caustic in the Cure of Certain Wounds and Ulcers by John Higginbottom
