Title: Massive Transfusion Pearls<br/>Author: Michael Winters<br/><a href='http://umem.org/profiles/faculty/141/'>[Click to email author]</a><hr/><p>
<strong><u>Massive Transfusion Pearls</u></strong></p>
<ul>
<li>
As discussed in previous pearls, massive transfusion (MT) is defined as the transfusion of at least 10 U of packed red blood cells (PRBCs) within 24 hours.</li>
<li>
While the optimal ratio of PRBCs, FFP, and platelets is not known, most use a 1:1:1 ratio.</li>
<li>
Though scoring systems have been published to identify patients who may benefit from MT (ABC, TASH, McLaughlin), they have not been shown to be superior to clinical judgment.</li>
<li>
A few pearls when implementing massive transfusion for the patient with traumatic shock:
<ul>
<li>
Monitor temperature and aggressively treat hypothermia.</li>
<li>
Monitor fibrinogen levels and replace with cryoprecipitate if needed.</li>
<li>
Monitor calcium and potassium. MT can induce hypocalcemia and hyperkalemia.</li>
</ul>
</li>
</ul>
