Editing Mass Transfusion Protocol (section)

== '''Process:''' ==

* Contact blood bank on 4630 (at Austin)
* Designate one person as liaison who will provide basic information to lab
* Pre-transfusion sample collected and sent
* pRBC and platelets take about 5 minutes, while FFP/cryo takes 30 mins
* Ratio 
** The common phrase is '1:1:1' but really what they mean is 4 units RBC, 4 units FFP and 1 bag of pooled platelets (which is somehow equivalent to 4 units)
*** 2024 update to Austin guidelines states 8 units pRBC : 1 bag pooled platelets = 4 units platelets : 4 bags FFP
** Give first bag FFP after 4 units of RBC have gone in
**
* FBE and coags every 30 mins
* Consider tranexamic acid (1g IV over 10 mins followed by 1g over 8 hours) - best evidence if given within 3 hours; worth giving up to 8 hours
* Recombinant factor VIIa can be considered as last resort in ongoing bleeding
