Which adverse effect is commonly associated with epidural morphine used for labor analgesia?

• A. Pruritus, Nausea, Vomiting, And Drowsiness
• B. Severe Hypertension
• C. Cardiac Arrhythmias
• D. Immediate Neonatal Respiratory Arrest

Answer: (A)

Epidural morphine during labor commonly produces central opioid effects, so the most typical adverse effects are itchiness (pruritus), nausea, vomiting, and drowsiness. The drug can be absorbed into the circulation and act on mu receptors in the CNS, leading to these sensations and sedation. Pruritus is a well-known and frequently seen side effect with neuraxial opioids, and nausea and vomiting reflect opioid stimulation of the medullary centers. While some respiratory depression can occur with higher systemic exposure, the immediate neonatal respiratory arrest is not a expected outcome with standard epidural dosing. Hypertension and cardiac arrhythmias are not typical adverse effects of epidural morphine in this setting.
