hypertension in pregnancy Flashcards
chronic hypertension
begins before pregnancy or prior to 20 weeksdoesn’t resolve within 12 weeks postpartumBP > 140/90
gestational hypertension
increased BP > 140/90 occurring after 20 weeks without proteinuriageneral term to classify until definitive diagnosis made
preeclampsia
after 20 weeks- elevated BP >140/90 – 2x 4 hours apart- proteinuria [> 300mg/24 hour urine collectionprotein/creat > 0.3 -or- urine dipstick > 1+]OR- thrombocytopenia (platelet 1.1 mg/dL)- impaired liver function (LFTs > 2x normal)- pulmonary edema- cerebral/visual symptoms
severe preeclampsia
SBP > 160 & DBP > 110+thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, cerebral disturbance
eclampsia
preeclampsia criteria +- grand mal seizure activity- increased maternal mortality
chronic hypertension superimposed preeclampsia
hypertension before 20 weeks +- new onset proteinuria- sudden increased BP (previously controlled)- any severe preeclampsia features
grand mal seizure
?
fibrinogen
?
fibrin split products
?
disseminated intravascular coagulation
pathologic diffuse clotting causing widespread bleeding/clotting (consumes large amounts of clotting factors = widespread int and/or ext bleeding)never primary diagnosis, always results from problem that triggered clotting cascade
cardiogenic pulmonary edema
congestive heart failure w or w/o fluid overload
non-cardiogenic pulmonary edema
leaky vessels allow fluid into extravascular space and alveoli
scotomata
altered vision
colloid osmotic pressure
gradient controlling whether fluid remains inside the capillary or moves into the interstitial space. The force to keep the fluid inside the vessel is the pulling pressure of the colloids, or proteins, present in the plasma
thrombocytopenia
low platelet count!!
