Comparing hemostatic resuscitation management of intraoperative massive bleeding with traumatic massive bleeding: a...

Area of Science:

• Physiology
• Medical Simulation
• Hematology

Background:

• Massive blood loss management differs between intraoperative and traumatic bleeding.
• Trauma patients lose undiluted blood, with replacement often delayed.
• Computer simulation was used to compare these bleeding scenarios.

Purpose of the Study:

• To compare appropriate blood component transfusion ratios in intraoperative versus traumatic massive bleeding.
• To analyze the impact of delayed fluid and blood replacement in trauma scenarios.

Main Methods:

• A modified multi-compartment dynamic model was implemented using STELLA 9.0.
• Simulated bleeding at 50 ml/min in both intraoperative and traumatic scenarios.
• Defined transfusion triggers for packed red blood cells (PRBC), fresh frozen plasma (FFP), and platelet concentrate (PC).

Main Results:

• The appropriate ratio of PRBC:FFP was 1:0.47 before platelet transfusion.
• The ratio of PRBC:FFP:platelets was 1:0.35:0.39 after initiating platelet transfusion.
• These ratios were consistent across both simulated bleeding scenarios.

Conclusions:

• The optimal ratio of transfused blood components did not differ significantly between intraoperative and traumatic massive bleeding scenarios.
• Simulation suggests a unified approach to blood component transfusion may be applicable.
• Further research could validate these findings in clinical settings.
