After performing a single-shot intrathecal anaesthetic consisting of 6.5mg of preservative free bupivacaine and 25 ug of fentanyl, the surgical incision is made and systemic hypotension ensued. To avoid significant decrease in uterine blood flow, first-line therapy to consider is

Provide additional inhaled nitric oxide to vasodilate the uterine vasculature

Increase maternal cardiac output with use of epinephrine

Use reverse Trendelenburg to decrease aortocaval compression

Question Category:

Correct Answer:
