Dr. Jeannie Callum, Dr. Andrew Petrosoniak and Dr. Barbara Haas join Anton in answering the questions: How do you decide when to activate the MHP? How do you know when it is safe to terminate the MHP? What lab tests need to be done, how often, and how should the results be shared with the clinical team? Once the dust settles, what do we need to tell the patient and/or their family about the consequences of being massively transfused? What should be the lab resuscitation targets? Why is serum calcium important to draw in the ED for the patient who is exsanguinating? How do we mitigate the risk of hypothermia? What can hospitals do to mitigate blood wastage? If someone is on anti-platelets or anticoagulants what is the best strategy to ensure the docs in the ED know what to give and how much? Until the results of lab testing come back and hemorrhage pace is slowed, what ratio of plasma to RBCs should we target? What's better, 1:1:1 or 2:1:1? Should we ever consider using Recombinant Factor 7a? If the fibrinogen is low, what is the optimal product and threshold for replacement? When and how much TXA? Anyone you wouldn’t give it to? and many more...
