Brief Summary

In summary, we determined the minimal infusion rates (median effective rate, ED50) of phenylephrine and noradrenaline in prevention of hypotension after spinal anesthesia for caesarean delivery and found that noradrenaline is more potent than phenylephrine by a factor of 12.6 for equivalent maternal blood pressure control. At the minimal infusion rates, noradrenaline does not provide greater cardiac output.
