Background: Intrathecal magnesium sulfate, an NMDA antagonist, has been shown to prolong analgesia and potentiates spinal anesthesia without significant side effects in parturients. This study aimed to explore the hypothesis that adding magnesium sulfate to intrathecal low-dose of bupivacaine and sufentanil can prolong the spinal analgesia in patients with severe pre-eclampsia. Methods: Sixty p...
