what are the 4 phases of hemostasis

1. Vascular Phase: vasoconstiction to decrease bleeding. vWF and PGI2 is released

2. Platelet Phase: platelets adhere and form a plug. Plateslets are activated and release- ADP, Ca, 5HT

3. Coagulation- form a clot. Extrinsic path required endo damage (TF, 7) intrinsic has it all in the cyto (12, 11, 9, 8)

Fibrinolysis: plasmin breaks up the fibrin that holds the clot together.
are defects in the vascular phase of coagulation usually acquired or inherited
Acquired

trauma, sepsis, steroids, aging

**congenital vascular disorders are rare
are defects in the platelet phase of coagulation usually acquired or inherited
Acquired (like vascular defects), common

ASA
ITP- idiopathic thrombocytopenia
are defects in the coagulation phase of coagulation usually acquired or inherited
either, this is really the one time we see CONGENITAL is in the coagulation

Congenital: deficit in clotting factor function or production (hemophilia or vWF)

Acquired- drugs like heparin, coumadin, AB or liver disease
are defects in the fibrinolysis phase of coagulation usually acquired or inherited
acquired

**DIC
if you pt has a bleeding disorder what q's do you want to ask in the history
C: how much, petechia, purpura,
O: recent or life long, length of episode
L: mucosal, GI. GU, intracranial, hemarthrosis
D:
E: liver disease, EtOH. meds, uremia, infection, malignancy, ASA, anticoagulants
R:
A: previous episode, previous transfusion- any reactions, why need the transfusion,
S:

Fx
if your pt has a bleeding disorder what should we look for on PE
Gen: rarely leads to dx but often gives an idea of extent of bleeding

Vitals: asses blood loww(HR, BP)

Gen: mental status change

BLood loss: examine site, it is oozing or gushing

SKin: ecchymosis, petechia, prupura

Mucoas: bleeding?

LN: can be indicative of AIDS, lymphoma, infectinon when supraclavicular or inguinal nodes are palpated

HSM: Liver- infiltrative process. Spleen- hypersplenism, myeloproliforative disorder, lymphoma

Joints: hemarthrosis

Pelvic and rectal exam
why is a LN exam important in your pt w/bleeding
Supraclavicular or inguinal nodes can suggest infection, lymphoma or AIDS
if your pt is bleeding bc of lymphoma whay might you expect on PE
splenomegaly
Supraclavicular or inguinal nodes
what are two exams that can be done to better asses bleeding
DRE
pelvic

Splenomegaly indicates sequestration of platelets or other blood products

HALLMARK is petechia that occurs spontaneously, after trauma/procedure
summarize primary coagulation disorders
seen more in men bc of x linked inheritance
*can also be acquired with anticoagulatn tx

bleeding is usually significant, deep and delayed by like 6-12 hours

**intracranial bleed, hemarthralgia, ecchymosis

can have signs of liver failure (jaundice), telangiectasia, HSM,

Lymphadenopathy can suggest lymphoma, leukemia, or infectious disease, AIDS

medical emergency
your 27 yo female presents with microangiopathic hemolytic anemia, thombocytopenia, purpura, and schistocytes. whats the deal
TTP

**can also have fever, renal failure, and neuro sx.

medical emergency
whats ITP

how is it dx
dx of EXCLUSION

IgG AB to platelets is made and platelets are destroyed

Kids: preceded by virus, self limited in kids

Adults: chronic form, more common in women. insiduous onset and unpredictable course
how is ITP diff in kids and adults
Kids: self limited, follows virus. its when you have IgG against platelets

Adults: chronic form, insidious onset, unpredictable course

**more common in women
does hemophilia A paint a representative picture of a coagulation disorder
yep

male, congenital, deep bleeds into mm and joints, UT, intracranial bleeds

Hemophilia has factor 8 deficit so PTT is long. they dont get GI or nose bleeds often
whats vWF
coagulation disorder
AD- decrease in vWF

see lots of mucosal and cutaneous bleeds, menorrhagia nad GI bleeds are common

simliar to hemophilia A but also has a platelet defecit

increased bleed time, normal platelet count, increased PTT
is hemophilia a coagulation disorder or platelet

what is the only lab that is increased?
coagulation
only the PTT is increased, its a factor 8 dificit

its in males and is sex linked recessive

deeo mm/joint bleeds. UT and intracranial bleeds (yep, sounds like a coagulation disorder, men, congenital, deep bleeds)

what is the promary coagulation disroder that is characterized by cutaneous and mucosal bleeds

what about the coagulation that is more deep bleeds in mm and joints, intracranial bleeds and UT
vWF

schistocytes are seen
what is in FFP (fresh frozen plasma)
coagulation factors,

good for pts w/DIC
what are hte 3 main goals of tx for a pt w/bleeding
1. stop the blood
2. treat the cause of bleeding
3. replace lost blood parts
what are some benefits of blood COMPONENT tx
1. you only give the pt what they need (DIC needs FFP bc it has coagulation factors)

2. decrease risk of transfusion reaction

3. economical

4. decreased transmission of disease

5. banked blood looses its clotting factors and platelets fast
whats PRBC
packed red blood cells

**replenish lost blood cell mass
FFP
used to replace clotting factors (2 5 7 9 10 11)

used to reverse cumadin tx

massive transfusions

tx TTP and DIC
your pt lost TONS of blood adn you need to transfule like a zillion units, what else do you want to add
FFP- make sure they get their clotting factors
ut oh, we gave that guy a bit too much coumadin, now he wont stop bleed. what can we do
FFP- it has coagulation factors
who gets platelet transfusions
thrombocytopenia <50,000 or abnormal bleeding

**increases the platelet count by like 10,000
