About this trial
Although, in the past years, an increasing use of ketamine in Traumatic Brain injury (TBI) has been reported as an adjunct to other sedatives, there is no evidence from randomized clinical trial to support this practice.
The BIKe (Brain Injury and Ketamine) study is a double-blind placebo controlled randomized multicenter clinical trial to examine the safety and feasibility of using ketamine as an adjunct to a standard sedative strategy in TBI patients.

Treatments tested in this trial
Ketamine
DrugRacemic ketamine® will be administered by continuous infusion in a prefilled 50 ml syringe at a concentration of 50 mg/ml, undiluted. The ketamine dose is 1 mg/kg/h, to a maximum dose of 120 mg/hour, which corresponds to an infusion rate of 0.02 ml/kg/h to a maximum rate of 2.4 ml/h.
Placebo
DrugPlacebo (NaCl 0.9%) will be provided in the same type syringes and administered at the same infusion rate as the IMP (0.02 ml/kg/h to a maximum rate of 2.4 ml/h).
Treatment groups
Trial outcomes
Primary outcomes
Change in therapeutic intensity of intracranial pressure (ICP) reducing measures, assessed by the TIL score (Therapy Intensity Level)
The primary efficacy endpoint will be the reduction in daily Therapy Intensity Level (TIL) score, based on the highest score in each item per day until study drug discontinuation (calculated every day on the available data at 7:00 AM). Scales for TIL score range from 0 (minimum) to 38 (maximum). Higher scores are related to worse outcome.
Secondary outcomes
Intracranial pressure (ICP)
The average of hourly validated intracranial pressure (mmHg) measurements per 24 hours
Duration of sedation
Total duration of the first period of sedative treatments (propofol, midazolam and/or dexmedetomidine)
Propofol
Total dose of propofol in mg per 24 hours
Mechanical ventilation
Total duration of mechanical ventilation, defined as all types of ventilation where positive end expiratory pressure is applied, expressed in cm H2O (5 cm H2O minimum).
