Summary

Resection surgery of brain tumors by craniotomy requires efficient brain relaxation intraoperatively in order to avoid injuries caused by the brain retractors (such as ischemic-reperfusion and cerebral oedema). The gold standard for the brain relaxation during a surgery is Mannitol 20%.

Molar sodium lactate is now used to induce brain relaxation in patients with traumatic brain injury and intracranial hypertension due to its osmotic effect. Furthermore, the injection of sodium lactate may lead to better neuronal metabolism during cerebral aggression, and may participate to the reduction of cerebral oedema and secondary injuries.

LSD is a pilot randomised trial which tries to assess the interest of intravenous administration of molar Sodium Lactate on the quality of brain relaxation in surgical resection of supratentorial brain tumors by craniotomy.

The primary outcome measure is the quality of brain relaxation, evaluated by neurosurgeon at the opening of the dura, by a validated brain relaxation scale.

Conditions

  • Sodium Lactate
  • Intracranial Hypertension
  • Brain Relaxation

Interventions

DRUG

Sodium Lactate

Sodium lactate is administered at 2.5mL/kg during the first surgical incision. Neurosurgeon will evaluate the brain relaxation using a validated scale once the dura is open. A stage 1(perfectly relaxed) or 2((acceptably relaxed) is considered satisfactory. Sodium Lactate and Mannitol 20% are used at an equimolar dose

DRUG

Mannitol 20% Infusion

Mannitol 20% is administered intravenously at a dose of 5mL/kg, so 1g/kg, during the first surgical incision. Neurosurgeon will evaluate the brain relaxation using a validated scale once the dura is open. A stage 1(perfectly relaxed) or 2((acceptably relaxed) is considered satisfactory.
