The effect of adding intrathecal magnesium sulphate to bupivacaine–fentanyl spinal anaesthesia

Abstract

In patients undergoing lower extremity surgery, the addition of IT magnesium sulphate (50 mg) to spinal anaesthesia induced by bupivacaine and fentanyl significantly delayed the onset of both sensory and motor blockade, but also prolonged the period of anaesthesia without additional side-effects.
