other Flashcards
deal with albumin
- not a reliable biomarker for nutritional state (influenced by a lot of inflammatory and infectious states)
QID MEANS
4 times a day
other causes of secondary hypertension
alcohol, pheochromoctyoma, substance use
workup of young person with HTN
renal US
BMP with creatinine
+/- sleep study if concerned for OSA
1 unit pRBCs should raise hct/hgb
3% and 1g/dL
when should you transfuse…
- the goal is to sustain adequate tissue oxygenation but it really depends on peoples ability to respond with increased cardiac output or oxygen intake
- look at HR (but make sure something else isn’t accounting for it)
- so below 7 in hemodynamically stable patients, below 8 in patients undergoing surgery or have cardiovascular disease
- Known CAD = less than 8
- symptomatic (CP-orthostatic hypotension-tachy unresponsive to IVFs) = less than 10
what to monitor with large volume transfusions
hypocalcemia (citrate binds it)
platelet indications for transfuing
less than 10K
if febrile less than 30K
how to manage elevated INR
INR 3-5: hold warfarin
INR 5-9: hold warfarin + give Vitamin K 2.5-5mg
*FFP not routinely advised in absence of bleeding.
how to drop INR before procedure (Should be below 1.5 (or even 1.0!)) (but 1.0 is hard to get too)
- intrinsic INR of FFP is 1.3
- give FFP
what is cryoprecipitate?
contains fibrinogen, factor 8, factor 13, VW factor and fibronectin
- used in ICU for major bleeding in vWD/factor deficiencies
- used in low fibrinogen states (DIC. goal fibrinogen over 100, liver disease and bleeding, massive transfusion protocols).
*pearl: does not reverse warfarin.
type and screen vs. type and cross
type and screen –
– used if transfusion is not likely. screend for ABO, Rh, and common antiboides
type and cross –
– same as above but they take blood from blood bank and mix it with patients blood to make sure there’s no hemolysis/reaction. It’s an additional step. Then specimen is owned by patient and good for 72 hours.
length of time for cross-match
about an hour (assuming everything goes perfectly)
how to write transfusion order
- be specific in indication
- rate of transfusion = 2 hours is generally fine unless bleeding fast. Or if concerned about volume overload (TACO) then 4 hours. OR if EF is really really low.
- make sure patient has adequate access (blood products need their own lines)
special requirements for transfusion
Only needed if…
- heme malignancy
- congenital immunodeficiency
Just call the blood bank (path interns usually have pager)
