During postpartum hypotension after an epidural, which action is the most appropriate first?

• A. Elevate the legs
• B. Place in left lateral position
• C. Administer a vasopressor
• D. Increase intravenous fluids

Answer: (B)

Postepidural hypotension is caused by the sympathetic block from the epidural combined with the gravid uterus potentially compressing the vena cava. The fastest way to counter this is to reposition the patient so the uterus no longer presses on the inferior vena cava and venous return to the heart improves. Placing the patient in the left lateral position does exactly that, shifting the uterus away from the major vessel and increasing preload, which raises blood pressure and improves perfusion to both mother and, if still postpartum, the uterus and surrounding tissues.

Other steps, like giving IV fluids or a vasopressor, may be used if hypotension persists after repositioning, but they don’t address the root cause as directly or immediately as relieving vena cava compression does. Elevating the legs can help with venous return but is not as effective for relieving IVC compression in this scenario.
