What is a common side effect of epidural anesthesia?

The choice highlighting itching and headache accurately identifies common side effects associated with epidural anesthesia. The use of epidurals during labor is a popular method for pain management, and while it is effective in alleviating pain, it can lead to specific adverse effects.

Itching occurs due to the opioids that may be administered through the epidural, as they can trigger histamine release in the body. This response is not uncommon and can range from mild to more pronounced. Additionally, headaches can arise as a result of dural puncture, which occurs if the needle inadvertently perforates the dural membrane during the procedure. This can lead to a condition known as a post-dural puncture headache, characterized by a severe, throbbing headache that typically worsens when sitting or standing.

Considering this context, the symptoms of itching and headache are well-documented in patients receiving epidural anesthesia, making this choice the most aligned with known side effects of this practice. The other options listed do not commonly correlate with this form of anesthesia, highlighting why this selection stands out in the context of discussed side effects.
