The Anaesthetic Ketamine as Treatment for Patients With Severe Acute Brain Injury
S-ketamine for Cortical Spreading Depolarisation in Patients With Severe Acute Brain Injury
Rigshospitalet, Denmark
400 participants
Sep 15, 2023
INTERVENTIONAL
Conditions
Summary
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.

- Pregnancy (all female participants aged ≤ 50 years will have a urine or blood hCG taken to control for pregnancy).
- Active anti-psychotic treatment before admission.
- Current abuse of ketamine.

Interventions
S-ketamines is an NMDA-receptor antagonist with sedative and analgesic properties. It will in the present trial be given in sedative doses (2-3 mg/kg/hour) in case of clustered SDs following a dosing algorithm according to SD occurrence.
Isotonic saline has the same appearance as S-ketamine with both being clear liquids with no bubbles or other distinguishing features.
