What is a common side effect of an epidural anesthesia in a laboring client?

When considering the common side effects of epidural anesthesia during labor, pruritus, or itching, is especially notable. This side effect occurs due to the interaction of the anesthetic agents with opioid receptors in the central nervous system.

Epidural anesthesia often includes the use of opioids, such as fentanyl or morphine, which can lead to histamine release in the body, resulting in symptoms like itching or pruritus. This is a well-documented side effect and is more frequently observed in patients who receive an epidural with opioid additives compared to those who receive a local anesthetic alone.

The other choices, although they may represent potential issues in different contexts, are not commonly associated with epidural anesthesia. For instance, while hypertension can occur, it is generally more related to fluid status or autonomic changes than to the administration of an epidural. Polyuria and dry mouth are also not typical side effects of epidural anesthesia specifically. Thus, pruritus stands out as the expected and observed side effect in this context.
