Clinical Trial 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.


Clinical Trial Description

It's a prospective, comparative, randomised, double blinded study. It will enroll 50 patients undergoing resection surgery of supratentorial brain tumor. They will be randomly divided in 2 groups of 25 patients each : Mannitol 20% and molar Sodium Lactate. The only difference between the 2 groups is the drug used for brain relaxation at the surgical incision : Mannitol or Sodium lactate. The outcome measures include quality of brain relaxation, need of "rescue" therapy to get an adequate brain relaxation, electrolytes alterations, change in lactate serum level, quantification of post operative brain swelling by MRI, time of extubation, Glasgow Coma Scale, neuropsychological evaluation, blood levels of Protein S100-β, NSE (Neuron-Specific Enolase) and GFAP Glial Fibrillary Acid Protein), morbidity and mortality during 30 days after surgery. ;
