2. Hemapheresis
Type of blood donation where whole blood is
withdrawn either from a donor or patient
wherein after removal, separation and
retention of the desired cellular elements or
plasma, the remaining products are
recombined and returned to the donor or
patient
3. Forms of apheresis
Plasmapheresis
leukapheresis or leukopheresis
lymphopheresis or lymphapheresis
erythropheresis
Apheresis is used as a treatment for many
diseases and conditions.
4. Donor Guidelines
At least 48 hours is the elapsed time after hemapheresis donation
A donor must not exceed more than 2 times in a week or 24 times
in a year unless otherwise allowed by blood bank physician
A donor must be tested to detect cytopenia
If a donor donates whole blood, at least 8 weeks must be elapsed
before he can donate for pheresis
Extracorporeal blood must not exceed 15% of the donor’s total
blood volume
If platelet pheresis is to be performed a donor must have above
150 x 109 /L platelet count
Possible adverse reactions to HES, steroids and/or heparin must be
determined and carefully evaluated.
5. Autologous Donor Selection
CRITERIA:
No age limit
No strict weight requirements
Hemoglobin/Hematocrit
Frequency: donations should not be more
frequent than every 3 days and the final
donation must be completed at least 3 days
prior to the scheduled surgical procedure
6. Types of Autologous Donations/Transfusions
Predeposit donation
Blood is drawn
sometime before the
anticipated transfusion
and stored, usually
liquid but occasionally
frozen
Intraoperative/peri-
operative autolgous
tranx
Blood is collected
during the surgical
procedure and usually
reinfused immediately
7. Types of Autologous Donations/Transfusions
Immediate pre-operative
hemodilution
Takes place in the
operating room when 1-3
units of WB are collected
and the patient’s volume is
replaced with colloid or
crystalloid. Blood is
reinfused during the
surgical procedure
Post-operative salvage
A drainage tube is
placed in the surgical
site and post-operative
bleeding is salvaged,
cleaned and reinfused.
