Reinfusion
Reinfusion of the red blood cells processed by the XTRA is under the control and supervision of the
physician in charge and can be accomplished by several different means:
• Processed blood can be held in the primary RBC bag until the bag becomes full. Then the bag can
be disconnected from the autologous transfusion circuit, hung, and reinfused according to normal
blood administration protocol, as described in AABB standards.
• Some of the processed blood can be moved into a transfer pack and handed off to the
anesthesiologist for reinfusion while processing of shed blood continues.
• Blood can be stored for later reinfusion. In this case, follow your institution's blood administration
protocol for appropriate labeling and blood storage requirements.
The Basic XTRA
The XTRA is equipped with an electronic red cell detector which determines when the appropriate
quantity of red cells has accumulated in the centrifuge bowl. This offers three modes for advancing the
blood processing phases:
• Automatic: The X
TRA will fill, wash, and empty the centrifuge bowl continuously until there is no
fluid left to process in the reservoir or until the wash solution is depleted or another waning
condition happens.
• 1 Touch: The X
TRA will start automatically when a certain level of fluid is reached in the reservoir,
and will fill, wash, and empty the centrifuge bowl continuously until there is no fluid left to
process in the reservoir or until the wash solution is depleted or another waning/alarm condition
happens.
• Manual: The operator has control over each phase transition: from Fill to Wash, and from Wash
to Empty. Options are available to prompt the operator when it is time to proceed to the Wash
phase, and to automatically proceed to the Empty phase.
WARNING
The American Association of Blood Banks provides recommendations
for expiration of salvaged blood (see Warning #11 on page 1-4).
WARNING
Do not reinfuse the patient’s blood from the primary RBC bag when
it is connected to the X
TRA autologous transfusion circuit. Reinfusion
from the primary reinfusion bag connected to the circuit could lead
to air embolism.
WARNING
To minimize the complications of particulate matter infusion and the
risk of air embolism, use of an in-line microaggregate filter on the
patient reinfusion line is STRONGLY RECOMMENDED.
WARNING
Do not reinfuse under pressure (i.e., do not use a blood pressure cuff
on the reinfusion bag). Reinfusion under pressure could lead to air
embolism.
WARNING
To reduce risk of air embolism, remove all air from the primary
reinfusion bag before handing the bag over for reinfusion.
