All of the following are major complications of massive transfusion, except:
**Core Concept**
Massive transfusion is defined as the replacement of one blood volume or more within 24 hours, which can lead to various complications due to **dilutional effects**, **citrate toxicity**, and **immune responses**. The underlying principle involves understanding the physiological and biochemical changes that occur with large-volume blood transfusions.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general complications associated with massive transfusion, including **hypothermia**, **coagulopathy**, **acid-base disturbances**, and **electrolyte imbalances**. These complications arise from the **dilution of clotting factors**, **citrate binding to calcium**, and **cold diuresis**.
**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it stated a known complication like hypothermia or coagulopathy.
**Option B:** Might be incorrect if it mentioned another recognized complication such as acid-base imbalance.
**Option C:** Could be incorrect if it listed electrolyte imbalance or another established complication.
**Option D:** Would be the choice that does not fit with the known major complications of massive transfusion.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **hypocalcemia** can occur due to citrate binding to calcium, and **hypothermia** can exacerbate coagulopathy. Monitoring and managing these complications are crucial in the setting of massive transfusion.
