Chp 4 Flashcards
edema
too much interstitial fluid in tissues and outside individual cells
intracellular edema
cloudy swelling win injured cells
anasarca
generalized, sever dedema
effusion
liquid in the pericardial, pleural, peritoneal, or joint cavities
ascites
effusion in the peritoneal cavity
hydrothorax
watery fluid in the pleural space
empyema
pus/purulent effusion in the pleural vavity
hydropericardium
watery fluid in the pericardial cavity
hydrocephalus
too much CSF
hydrocele
extra fluid within the membrane around the testis
hydrosalpinx
too much fluid in the fallopian tube following gonorrheal or other salpingitis
ileus
too much fluid in the small bowel
seroma
non-infected fluid in the surgical incision
loculated effusion
more than one compartment, due to scarring, harder to drain
blister
fluid in the epidermis or between dermis and epidermis
bulla vs vesicles
big vs little blisters
mechanisms in with edema can form (5)
1) excess total body fluid
2) increased pressure in the small veins of the body
3) decreased total plasma protein/albumin content
4) lymphatic vessel obstruction
5) leaky vessels from inflammation
examples of causes of edema
1) excess total body water- iatrogenic fluid overloading, kidney failure
2) increased venous pressure - CHF, pericardial disease, pregnancy, thrombus
3) decreased blood protein content - malnourishment, malabsorption, liver failure
4) lymphatic obstruction - filariasis, surgery, radiation, cancer
5) other - trauma, lead poisoning
chylous effusion
result from damaged lymphatics, thoracic duct, and produce turbid, lipid rich fluid
transudate
salt water, vessels keep protein in the bloodstream
exudate
leaky vessels produce protein rich edema
cardiac edema
edema first appearing in the feet after standing
from CHF
renal edema
edema first appearing around the eyes
total-body water overload/low blood albumin
liver disease
edema first appearing as excess fluid in the abdomen
low blood albumin plus increased resistance to portal venous flow
