Q

What are the TX of hypokalemia

A

Remember that NDMB should be reduced 25-50% since hypokalemia causes increased sensitivity.

Q

How to calculate your NPO hours?

A
27
Q

What are the EBV for

Neonates:

Premature:

Full term

A
28
Q

EBV for Infantd

A

Infants 3-12 months

80 ml/kg

29
Q

Adults

Males

Females

A
30
Q

What can NaCl cause?

A

Hyperchloremic, hypernatremic metabolic acidosis if >3-4 L given

31
Q

How do you calculate Hct?

A

Hgb x 3

32
Q

How to replace blood loss?

LR/NS/Plyte:

Colloids:

PRBC:

A
33
Q

What is the EBV formula?

A
34
Q

Blood Component Therapy

Why do you need whole blood for?

What is the Hct?

What does it contain?

How much does it raise Hct?

A
  • massive infusion therapy
  • 40% HCT
35
Q

PRBC

what is HCT?

How much does it increase Hct?

What is the volume?

A

Tubing should contain 170-230 mm fliter

Warm it - Hypothermic effects and lower level of 2,3 DPG in stored blood cause leftward shift of oxyHgb dissociation curve

Infuse NS

36
Q

Know banked blood preservatives

what does the different additives do?

A
37
Q

What happens to older blood?

A

The older the blood the more acidotic it gets

38
Q

When can you not give O+

A

pregnant women

39
Q

What are the two things that the TEG are looking at?

what does it require?

A

Coagulation

Fibrinolysis

frequent calibrations.

40
Q

Initiation

A

Time of latency from start of test to initial fribrin formation

41
Q

Amplification

A

Time taken to achieve a certain level of clot strength

42
Q

Alpha

A
  • angle (slope between R and K); measures the speed at which fibrin build up and cross linking takes place, hence assesses the rate of clot formation
43
Q

Definition: TMA

MA?

A

time to maximum amplitude

Maximum amplitude - represents the ultimate strength of the fibrin clot; i.e overall stability of the clot

44
Q

Important TEG patterns

A
45
Q

Important TEG form and treatment

A
46
Q

Citrate Intoxication

A

Complications of massive blood transfusion therapy
Ø Citrate intoxication: from the addition of CPD as
preservative for stored blood; can occur with
rapid transfusion (>150ml/min)
l Citrate metabolized by liver; if rate of transfusion
exceeds 1 unit of blood per minute in an adult,
decreased calcium may result (binds calcium and
magnesium) l Due to accumulation of citrate chelating serum
calcium l Pediatric patients and those with liver disease more
likely to become intoxicated

47
Q

Symptoms of Citrate Intoxication

and

Treatment

A

S ymptoms of citrate intoxication
Ø Hypocalcemia

Ø Hypotension

Ø Increased LVEDP

Ø Increased CVP

Ø Prolonged QT interval

Ø Hypomagnesemia
l Tachyarrhythmias, TdP, refractory V Fib

Treatment:

Ø Calcium or magnesium

Ø Citrate will be metabolized quickly in
Kreb’s cycle so symptoms may abate
before treatment needed

48
Q

when do you see Dilutional coagulopathy

A

Ø Seen with massive transfusions > 1 EBV

Ø Microvascular bleeding

Ø Hematuria

Ø Bleeding at IV sites

Clinically oozing

Ø Increased PT/PTT

Ø Decreased platelets

(>10 units)

49
Q

What is the tx of Dilutional coagulopathy

A

Treatment for dilutional coagulopathy
Ø Surgically control the bleeding

Ø Keep patient warm

Ø Maintain perfusion and euvolemia

Ø Don’t overhydrate and dilute patient

Ø Consider FFP, platelets

Ø Consider Vitamin K, DDAVP (enhances
platelet adhesiveness)

50
Q

Citrate combines to?

A

calcium

51
Q

really common complication of blood transfusion

A
52
Q

most commonly transfused virus in blood transfusion

A

CMV virus

  • if patient is a transplant you have to ask for it to be CMV negative and irradiated blood.
53
Q

FFP indications?

what does it contain?

A
54
Q

How long can you store FFP?

A

can be stored for a year

55
Q

When do you give platelets?

A

1 unit of platelet per 10 kg of bodyweight

it has 6-7 donor units and will raise count 5 - 10

56
Q
A
57
Q

What is the normal platelet count?

what is the trigger?

A
58
Q

When do yo give Cryo?

A
