A 24-year-old Jehovah’s Witness who was in a high-speed motorcycle collision undergoes emergent splenectomy. His estimated blood loss was 1500 mL. Which of the following strategy should be employed for his resuscitation?
**Core Concept**
The patient requires massive transfusion due to significant blood loss from a splenectomy, necessitating a balanced approach to maintain tissue perfusion while minimizing the risk of complications.
**Why the Correct Answer is Right**
The correct strategy involves the use of type O negative blood, which is a universal donor type that can be transfused to anyone. The rationale behind this is that type O negative blood lacks A and B antigens on its surface, making it compatible with recipients who have A, B, AB, or O blood types. Additionally, the absence of Rh antigens (since it is Rh null) eliminates the risk of Rh sensitization. In the context of massive transfusion, the goal is to maintain a balanced ratio of red blood cells, plasma, and platelets to prevent coagulopathy.
**Why Each Wrong Option is Incorrect**
**Option A:** Transfusion of type-specific blood would be more time-consuming and may not be immediately available, delaying the resuscitation effort.
**Option B:** Administration of fresh frozen plasma (FFP) alone would not provide the necessary red blood cells to maintain oxygen delivery to tissues.
**Option C:** Use of platelet concentrates without red blood cells and plasma would not adequately address the complex coagulopathy that can occur with massive transfusion.
**Clinical Pearl / High-Yield Fact**
In massive transfusion scenarios, the goal is to maintain a balanced ratio of red blood cells to plasma to platelets to prevent coagulopathy. A widely accepted ratio is 1:1:1, although this may vary depending on institutional protocols.
**Correct Answer:** C. Use of type O negative blood and a balanced ratio of red blood cells to plasma to platelets.
