Red Cell Spillage
Under normal conditions there should be little or no red cell spillage. The effluent
line sensor should mitigate any spillage. During the WASH mode, two conditions
may especially result in red cells spilling over into the waste bag:
1. Overfilling of the bowl during manual processing.
2. Excessive flow rate of saline solution due to operator reprogramming of
parameters.
Warning: Too low a flow rate will give a poor wash due to insufficient
turbulence and mixing in the RBC layer.
Managing the
Inventory of Air
The disposable bowl, as received from the factory, is full of sterile air. During each
recovery mode, air is passed over into the waste bag while the bowl is filling, and
is returned from the waste bag during the emptying of the bowl. It is important to
permit this air to return to the bowl from the waste bag to avoid a negative
pressure in the bowl during emptying.
Note: If the waste bag fills and must be either changed or emptied, this must be
carried out while the bowl is empty (and filled with air). The waste bag may be
partially emptied at any time as long as the fluid level in the bag is not below the
waste bag drain port.
Pressure
Reinfusion
Warning: Do not use a pressure cuff or any other mechanical device with the
Cell Saver 5+ System. Pressure reinfusion can result in the fatal infusion of air
into the patient.
The user will find that gravity reinfusion of washed cells is accomplished more
rapidly than infusion of the usual unit of allogeneic, concentrated cells. This is
because red cells suspended in saline are of lower viscosity, and because washed
cells are at room temperature.
The blue reinfusion line comes primed with 40 ml of sterile air from the factory.
At the first EMPTY mode this air is sent into the reinfusion bag; therefore, DO
NOT PRESSURE REINFUSE.
Should it become necessary to remove air from the reinfusion bag, this may be
accomplished by closing the clamp on the line between the reinfusion bag and
the patient, inverting the reinfusion bag, and opening one of the transfusion line
clamps on the bag and squeezing the bag to remove its air.
Another method of transfusing the washed autologous red cells is by transferring
the blood from the reinfusion bag to a secondary transfer pack. The air is burped
from the secondary transfer pack into the reinfusion bag. The transfer pack is
sealed and given to the anesthesiologist for infusion to the patient. This method
of infusing the washed autologous red cells is helpful if the machine is located at
a distance from the patient and direct reinfusion of the blood is not possible.
