1

Autotransfusion

person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood

2

Autotransfusion

person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood

3

Two main kinds of autotransfusion

1. Autologously "pre-donated"
2. Collected during and after the surgery using an intraoperative blood salvage device (ex. cell saver)

4

Cell Saver

Intraoperative cell salvage machine suctions, washes, and filters blood so it can be given back to the patient's body instead of being thrown away

5

What's the limit to the amount of blood that can be given back to the patient?

No limit because the blood is recirculated

6

What's the limit to the amount of blood that can be given back to the patient?

No limit because the blood is recirculated

7

Types of intraoperative cell savers

Discontinuous
Continuous (CATS)

8

Types of intraoperative cell savers

Discontinuous
Continuous (CATS)

11

CATS

continuous autotransfusion system

12

CATS

continuous autotransfusion system

13

Is the reinfusion bag used to reinfuse patient? Why or why not?

No, use transfer pack; blood must be filtered; air can get to the patient

14

What disposables are involved when setting up the cell saver?

Aspiration set
Heparinized saline
collection reservoir
bowl
wash solution
collection bag
blood filter, lipid filter, leukocyte reduction filter
transfer packs

15

What disposables are involved when setting up the cell saver?

Aspiration set
Heparinized saline
collection reservoir
bowl
wash solution
collection bag
blood filter, lipid filter, leukocyte reduction filter
transfer packs

16

How is the aspiration set usually packaged?

usually packaged separately from washing set

17

What type of tube is the aspiration set?

Dual lumen tube
-Anticoagulant line with drip chamber and roller clamp control
-suction line for salvages blood mixed with anticoagulant

18

Anticoagulant Components

Heparinized Saline (30,000 units Heparin/1000 mL saline)
CPD (citrate-phosphate dextrose)
ACDA (anticoagulant citrate dextrose solution- Solution A)

19

What is the capacity of the collection reservoir?

3000 to 4000 mL capacity

20

Describe the filter on the collection reservoir.

Gross filter or 30-1000 micron filter

21

What is the size of the bowl?

Varying sizes from 50mL to 250 mL

22

What are the 3 types of bowls/disks?

1. Turbo bowl (Medtronic autolog)
2. Disk (CATS)
3. Latham Bowl

23

What are the 3 types of bowls/disks?

1. Turbo bowl (Medtronic autolog)
2. Disk (CATS)
3. Latham Bowl

24

What is the CATS system washing process?

1. Separation phase (Hct 80%)
2. Washing phase
3. Second separation phase (Hct 60-65%)

25

What are the main phases of washing cells?

1. Fill
2. Wash
3. Empty

26

What are the main phases of washing cells?

1. Fill
2. Wash
3. Empty

27

Fill Phase

-Centrifuge/accelerates to the speed selected on the centrifuge speed control (~5600 rpm)
-Pump begins rotation, transferring reservoir contents to was bowl
-Application of centripetal acceleration separates the components of the fluid according to their weight (layering)

28

Fill Phase

-Centrifuge/accelerates to the speed selected on the centrifuge speed control (~5600 rpm)
-Pump begins rotation, transferring reservoir contents to was bowl
-Application of centripetal acceleration separates the components of the fluid according to their weight (layering)

29

During the fill phase, the wash bowl filling continues until what?

Until the buffy coat reaches the shoulder of the wash bowl

30

What happens in the "auto mode" of the fill phase?

Autotransfusion devices have automatic buffy coat sensor which is calibrated to detect a fill bowl.
Fill phase--> wash phase automatically
