AUTOTRANSFUSION OVERVIEW
Autotransfusion is a non-invasive procedure in which autologous blood lost by or removed
from a patient undergoing surgery in an operating room is subsequently reinfused to the patient. Component preparation
may also be carried out and products sequestered prior to surgery for reinfusion following completion of surgery and securing
of bleeding points and surfaces. The sequestered products include red cells, plasma, and platelet concentrate.
The latter may also be employed to prepare platelet gel, which can be used as a surgical sealant with properties to promote
healing (platelet-derived growth factors).
ADVANTAGES
OF AUTOTRANSFUSION OVER ALLOGENEIC TRANSFUSION
Blood-related
diseases have focused attention on the risks of allogeneic transfusion and have resulted in increased interest in autotransfusion.
There are several benefits to autotransfusion.
1.
Transmissible viral disease risk is eliminated, as well as other non-screenable viral blood-transmitted diseases.
2. Cross-matching errors are
eliminated.
3.
Patients opposed to allogeneic transfusion for religious reasons, such as Jehovah's Witnesses have often accepted the autotransfusion circuit as simply an extension of their bodies'
natural circulation.
4.
Autologous blood provides significant additional assurance when operating on surgical subjects with multiple blood group
antibodies or rare blood phenotypes.
5.
Banked blood inventory may be conserved, particularly at times of blood shortages. Significant cost containment
may be realized.
INDICATIONS FOR AUTOTRANSFUSION
This service incorporates the collection, concentration, washing and
reinfusion of autologous blood and/or autologous blood components during surgical, or other trauma treatment procedures, where
autologous blood may be properly salvaged from wounds and/or body cavities in "autotransfusion" support of the patient's
blood transfusion requirements. Such areas of application may include, but are not necessarily limited to, the following:
- Cardiovascular surgery
- Orthopedic surgery
- Trauma surgery
- General Surgery
- Neurosurgery
- Plastic/Reconstructive surgery
- Obstetric/Gynecologic
surgery
- Emergency Room/Trauma Center treatment
Additionally, this device is intended for use in the collection, concentration
and reinfusion of autologous blood components that may be sequestered from venous access during the perioperative period in
appropriate elective or emergent surgery in order to provide support of patient's blood component transfusion requirements.
Such areas of application may include, but are not necessarily limited to the following:
- Cardiovascular surgery
- Orthopedic
surgery
- ENT (ear-nose-throat) surgery
- General Surgery
- Neurosurgery
- Plastic/Reconstructive surgery
- Obstetric/Gynecologic
surgery
- Trauma surgery
Autotransfusion is indicated when:
1. Red cells conservation is chosen by the physician
or the patient as an alternative to allogeneic blood transfusion.
2. Replacement with allogeneic blood may increase morbidity
and mortality.
3.
No other blood is available and the patient's hematocrit is lower than 24%.
4. No blood can be cross-matched or more blood is
required than is readily available.
5.
The religious beliefs of the patient permit acceptance of fresh autologous blood, but not Blood Bank
products, as with some Jehovah's Witnesses.
