Summary

Mannitol is widely used in patients with elevated intracranial pressure. In neurosurgical field, especially in large size or with brain edema, it is necessary to decrease brain volume to facilitate surgical approach. In general, 0.25 -1.5g of mannitol per kilogram has been known to decrease ICP effectively. But there are some debates in regard to appropriate dose of mannitol.

Conditions

  • Supratentorial Neoplasms

Interventions

DRUG

0.25g/kgof 20% mannitol

When the neurosurgeon starts the drilling of skull, 0.25g/kg of 20% mannitol administered through the IV catheter with fulldrip. Neurosurgeon evaluate the degree of brain relaxation after dura opening in 4 point scale ( 1=bulging brain, 2=firm brain, 3-satisfactorily relaxed, 4=perfectly relaxed).

DRUG

0.5g/kg of 20% mannitol

When the neurosurgeon starts the drilling of skull, 0.5g/kg of 20% mannitol administered through the IV catheter with fulldrip. Neurosurgeon evaluate the degree of brain relaxation after dura opening in 4 point scale ( 1=bulging brain, 2=firm brain, 3-satisfactorily relaxed, 4=perfectly relaxed).

DRUG

1.0g/kg of 20% mannitol

When the neurosurgeon starts the drilling of skull, 1.0g/kg of 20% mannitol administered through the IV catheter with fulldrip. Neurosurgeon evaluate the degree of brain relaxation after dura opening in 4 point scale ( 1=bulging brain, 2=firm brain, 3-satisfactorily relaxed, 4=perfectly relaxed).

DRUG

1.5g/kg of 20% mannitol

When the neurosurgeon starts the drilling of skull,1.5g/kg of 20% mannitol administered through the IV catheter with fulldrip. Neurosurgeon evaluate the degree of brain relaxation after dura opening in 4 point scale ( 1=bulging brain, 2=firm brain, 3-satisfactorily relaxed, 4=perfectly relaxed).
