Traumatic Brain Injury Clinical Trial
— KETA-BIDOfficial title:
S-ketamine for Cortical Spreading Depolarisation in Patients With Severe Acute Brain Injury
Cortical spreading depolarisations are pathological depolarisation waves that occur frequently after severe acute brain injury and has been associated with poor outcome. S-ketamine has been shown to inhibit cortical spreading depolarisations. The aim of the present study is to examine the efficacy and safety of using S-ketamine for treatment of patients with severe acute brain injury, as well as the feasibility of the trial design.
