	* FWB ~~remains an~~ important tool used in modern military medicine although military physicians often do not have extensive training in its proper use.		* FWB has also shown to have benefit over component therapy when used in resuscitation of bleeding patients who are anticipated to have need of massive transfusions
	* FWB is not extensively used in civilian settings due to the availability of fractionated products which were developed to meet demand for large-scale system needed to collect and distribute blood.

==Background==
* Fresh Whole Blood (FWB) has been used extensively to resuscitate casualties in military conflicts since World War I.
* FWB has been shown via retrospective studies to improve early and late survival as compared to stored component therapy.
* FWB remains an important tool used in modern military medicine although military physicians often do not have extensive training in its proper use.
* FWB is not extensively used in civilian settings due to the availability of fractionated products which were developed to meet demand for large-scale system needed to collect and distribute blood. Using fractionated products allows for prolonged storage and improved resource utilization of donated blood.

** FWB is not FDA-approved

==Indications==
* Not use for convenience or as an alternative to component therapy if said blood products are readily available
* Use in trauma casualties who are anticipated to require massive transfusions based on retrospective studies showing benefit to FWB over component therapy
* Use in patients with clinically significant shock or coagulopathy when optimal component therapy is unavailable or stored component therapy is not adequately resuscitating patient with immediate life-threatening injuries
* Use when component therapy inventories are depleted or excepted to be depleted as in mass casualty situation

==Management==
* Decision to Use
** Made by physician who has knowledge of the clinical situation and availability of compatible blood components
** Limit use of FWB to indications noted above
** Made in consultation with appropriate ancillary stakeholders to include blood bank officer in charge, trauma director, chief of staff of the military treatment facility
** Ensure FWB is type-specific matched to casualty
** Annotate decision to use FWB in medical record
* Precautions
** No universal donor
** Female casualties of child bearing potential must be Rh match
** Blood types on identification tags are known to be incorrect on occasion
** Non-standard equipment may lead to coagulation during transfusion process
* Planning Factors for FWB Donation Program
** Establish robust pre-screen donor pool if possible
** Rapidly establish ABO/Rh status of donors and casualties
** Adhere to same screening, drawing, labeling, and issuing standards as for approved component products
** Perform on-site testing of potential donors using rapid screening immunoassays then retrospective testing should be performed and documented in medical chart as well

==Procedure==
* Reference joint clinical practice guidelines for detailed FWB transfusion protocol
* After 24 hours destroy all room temperature-stored units
* If refrigerated within 8 hours of collection, store up to 5 days. Note that FWB product only will have RBCs and plasma if transfused after refrigeration as platelets will be non-viable once they are cooled to 4 degrees C

==Disposition==
* FWB will continue to be a lifesaving addition to the military physician taking care of seriously injured on the battlefield despite not being FDA-approved therapy.
