  • Antibody identified
Study These Flashcards
A

Do phenotyping of transfused unit(s) for corresponding antigen

25
Transfusion reaction investigation w/in 24hrs - DONOR'S BLOOD -> - If febrile = do culture & sensitivity -> - inject 10-20ml of culture broth into the unit(s) -> - agitate units and withdraw broth -> - gram or acridine orange stain
IDENTIFY ORGANISM
26
Transfusion reaction investigation w/in 24hrs - DONOR'S BLOOD -> - If febrile = do culture & sensitivity -> - inject 10-20ml of culture broth into the unit(s) -> - agitate units and withdraw broth -> - use broth for inoculation of culture
IDENTIFY ORGANISM
27
Transfusion reaction investigation w/in 24hrs - DONOR'S BLOOD -> - Perform an anti humanglobulin (AHG) crossmatch with pre-and post transfusion specimens
Compare pre and post
28
Transfusion reaction investigation w/in 24hrs - DONOR'S BLOOD -> - Visually inspect for hemolysis, clots or discoloration -> - Both tubing & donor unit (+) hemolysis
- physical hemolysed unit | - addition of a solution to the unit that had caused red cell destruction
29
Transfusion reaction investigation w/in 24hrs - DONOR'S BLOOD -> - Visually inspect for hemolysis, clots or discoloration -> - Tubing (+) hemolysis, donor unit (-) hemolysis
Faulty infusion device
30
Transfusing red blood cells (RBCs) that have been in storage for > 14 days has been associated with increased risk of
- organ failure in critically ill children - risk of immunologic - vasoregulation - adverse hypercoagulation effects increased
31
Estimated volume per unit of blood products: - Packed RBC (PRBC): - Whole blood: - Fresh Frozen plasma (FFP): - Platelets: - Cryoprecipitate:
- Packed red blood cells (PRBCs): 300 mL/ unit - Whole blood: 450-500 mL / unit - Fresh frozen plasma (FFP): 250-300 mL / unit - Platelets: 40-50 mL/ unit Crvyoprecipitate: 10-12 mL/ unit - Cryoprecipitate: 10-12mL/ unit
32
Blood Volume by Age - Premature infant: - Full-term neonate: - Older infant: - >12 mo:
Premature infant: 100 mL/kg Full-term neonate: 85 mL/kg Older infant: 75 mL/kg >12 mo: 70-75mL/kg
33
Transtusing a pediatric patient with 4 cc/kg will increase
hemoglobin by 1 g/dL
34
Transfusing 1 unit in an adult patient will raise
hemoglobin by 1 g/dL (or HCT by 3%)
35
FFP transfuse volume
10-15 mL/kg
36
Routine FFP transtusion rates should not exceed ___ because of the risk of hypotension caused by low ionized calcium during the FFP infusion.
1 mL kg / min
37
Hypotension from excess FFP can be treated with
10 mg/kg CaCl or 100 mg/kg calcium gluconate IV over 5-10 minutes
38
For patients with massive bleeding who are at risk for death secondary to hemorrhage, give FFP as __ as possible, paying attention to ionized calcium levels because large volumes ot plasma and red cells will decrease ionized calcium concentrations.
fast
39
For patients with known clotting factor deticiencies, __ of FFP will raise tactors levels 15%-20%
10-15 mL/kg
40
Pheresed platelet units have a volume of
6-10 random donor units
41
- An excellent source of fibrinogen and tactor VIII, tactor XH, and Von Willebrand's tactor - Administering 1-2 bags tor every 5-10 kg will raise fibrinogen levels 60-100 mg/dL
Cryoprecipitate
42
A “massive transfusion” in a child is when approximately __ circulating blood volume is replaced within 24 hours
one
43
Some clinical parameters may predict the need tor a massive transfusion during active bleeding
- Severe tachycardia or hypotension tor age - Base deticit  6 or more - Lactate = 4 mmol/L - International normalized ratio 1.5 or more - Hemoglobin  9 g/dL upon admission or less
44
Cons ider us ing massive transtusion strategies when a child is anticipated to need more than two traditional __ mL/kg transfusions of PRBCs during one resuscitation (equivalent to about > 6-8 PRBC units for an adult)
15
45
When transfusing through small IV catheters (22 gauge and 24 gauge), bolusing with a __mL sy ringe may be the most efficient way to deliver fluids and blood products rapidly
10-20
46
Why use 1:1:1 ratio if a patient is at risk tor massive transfusion, PRBCs, FFP, and platelet transtusion?
- Helps avoid coagulopathy and 1s associated with reduced mortality trom hemorrhage in adults - Use of blood products in this ratio should continue until the lite-threatening bleeding has stopped; at this point use more restrictive transfusion criteria. Formulas tor calculating volumes of each product should be used
47
It FWWB is available, consider using it as a substitute for
- PRBCs, - FFP, and - platelets
48
has been used to reduce blood loss and restore hemostasis in combat casualties with coagulopathy associated with hemorrhagic shock
