MTP Pack (1:1:1 Ratio) • 6 U RBCs • 6 U FFP ** • 1 Dose Platelets
MTP - FFP Facts no typing = 4 units only thawed product = no delay at FMC and PLC • 30 min delay at RVH
Patient Considerations • Acidosis (pH 7.2) • Hypocalcemia ( 1.2 mmol/L) • Hypothermia (35°C) • Heparin Reversal – Protamine • Warfarin Reversal – Octaplex and Vit K • CRF - DDAVP
