An exudate is a fluid released by an organism through pores or a wound, a process known as exuding or exudation. [1] ... Types of exudates: serous, serosanguineous ...
A seroma contains serous fluid. [1] This is composed of blood plasma that has seeped out of ruptured small blood vessels and the inflammatory fluid produced by injured and dying cells.
In physiology, serous fluid or serosal fluid (originating from the Medieval Latin word serosus, from Latin serum) is any of various body fluids resembling serum, that are typically pale yellow or transparent and of a benign nature.
An accurate diagnosis of the cause of the effusion, transudate versus exudate, relies on a comparison of the chemistries in the pleural fluid to those in the blood, using Light's criteria. According to Light's criteria (Light, et al. 1972), a pleural effusion is likely exudative if at least one of the following exists: [31]
Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]
A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity.The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane.
The serum-ascites albumin gradient (SAAG) is the most useful index for evaluating peritoneal fluid and can help distinguish ascites caused by portal hypertension (cirrhosis, portal vein thrombosis, Budd-Chiari syndrome, etc.) from other causes of ascites.
It is described as an exudative maculopathy, characterised by multiple recurrent serosanguineous retinal pigment epithelial detachments. [3] Elevated reddish to orange lesions on fundus examination, dilated inner choroidal vessels, and polypoidal vascular structures beneath the retinal detachment are other features of PCV. [4]
