Magnesium and Intraoperative Blood Loss in Meningioma Surgery

Participant gender:
All
Summary
Meningioma is the most common central nervous system tumor and craniotomy with tumor removal was associated with moderate blood loss and blood transfusion. Magnesium has hypotensive effect and probably reduce intraoperative blood loss. Whether or not magnesium sulphate can reduce intraoperative blood loss and improve postoperative cognitive function is still inconclusive. So the investigators conduct the randomized control trial to compare the effect of magnesium with placebo control in blood loss and cognitive function in meningioma patient undergoing craniotomy.
