Shoulder dystocia result in the foilnwing except:
**Core Concept**
Shoulder dystocia is a complication that occurs during vaginal delivery, where the anterior shoulder of the fetus cannot pass below the pubic symphysis after the delivery of the head. This can lead to a range of severe consequences for both the mother and the baby. The underlying mechanism involves a combination of factors, including fetal size, maternal pelvis size, and the presence of certain medical conditions.
**Why the Correct Answer is Right**
The correct answer is related to the consequences of shoulder dystocia. The mechanism behind shoulder dystocia involves the entrapment of the anterior shoulder of the fetus, which can lead to a range of severe consequences, including brachial plexus injury, clavicle fracture, and even birth asphyxia. The brachial plexus is a complex network of nerves that supply the arm, and injury to this area can result in permanent nerve damage and loss of motor function.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is a known consequence of shoulder dystocia. The brachial plexus injury is a direct result of the entrapment of the anterior shoulder of the fetus.
* **Option B:** This option is incorrect because it is not a direct consequence of shoulder dystocia. While maternal hypotension can be a contributing factor to shoulder dystocia, it is not a direct result of the condition.
* **Option C:** This option is incorrect because it is a known consequence of shoulder dystocia. The fracture of the clavicle is a common injury associated with shoulder dystocia due to the entrapment of the anterior shoulder of the fetus.
* **Option D:** This option is incorrect because it is not a direct consequence of shoulder dystocia. While maternal hypoxia can be a consequence of shoulder dystocia due to birth asphyxia, it is not a direct result of the condition.
**Clinical Pearl / High-Yield Fact**
Shoulder dystocia is a medical emergency that requires prompt recognition and management. The McRoberts maneuver, which involves hyperflexion of the mother's legs, is a common technique used to relieve the entrapment of the anterior shoulder of the fetus.
**Correct Answer: C. Clavicle fracture is a known consequence of shoulder dystocia.**
