Обзор
The investigators plan to undertake a phase II study to investigate the efficacy and side effects of intravenous ketamine to reduce neuroexcitotoxicity, and thus provide neuroprotection in patients diagnosed with acute ischemic stroke.
Подробное описание
After obtaining informed consent, patients enrolled in the 'study drug' arm of the trial will receive Ketamine (1 mg/ml solution prepared in normal saline) infusion at a rate of 20 mg/h for a period of 24 hours. The infusion will start at a rate of 5 mg/h, and then gradually tapered up during the first 3 hours by 5 mg an hour. Similarly, the infusion rate will be gradually tapered down at a rate of 5 mg/h during the last 3 hours of infusion. The patients randomized to the 'placebo arm' of the trial will receive normal saline infusion at the same rates. In order to prevent the psychogenic adverse effects associated with Ketamine, the patients will be administered Midazolam at a dose of 1 mg IV every 4 hours. Midazolam will also be administered at the same rate to the patients randomized to the placebo arm. Blood Ketamine levels will be measured before starting the treatment, and daily while the infusion is on. While receiving treatment, the patients will be admitted to the telemetry floor in the hospital, on a monitored bed.
