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 a common complication of massive transfusion: **hypothermia**, **coagulopathy**, **acid-base disturbances**, and **electrolyte imbalances**. These complications arise from the infusion of large volumes of blood products, which can be colder than body temperature and contain citrate as an anticoagulant.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we cannot determine why it is incorrect.
**Option B:** Similarly, without the specific option, we cannot assess its accuracy.
**Option C:** This option's correctness depends on the context not provided.
**Option D:** The same issue applies, as the option text is missing.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **hypocalcemia** can occur due to citrate binding to calcium, and **hypokalemia** or **hyperkalemia** can result from the transfusion of stored blood. Monitoring and correcting these electrolyte imbalances are crucial in managing patients receiving massive transfusions.
**Correct Answer:** D. Hypothyroidism
