Uitkomstmaten
Primaire uitkomstmaten
1. Main safety endpoint: Clinical deterioration, defined as a decrease on the Glasgow Coma Scale of more than 2 points and/or a decrease of 4 or more points on the NIHSS;<br>
2. Primary clinical endpoint: Comparison of the change in neurological deficits, quantified by the National Institute of Health Stroke Scale (NIHSS) during helium therapy.
Achtergrond van het onderzoek
In the treatment of acute cerebral ischemia the aim is to preserve and salvage the penumbra and to protect the brain from reperfusion injury. Recently, helium was shown to provide neuroprotection in an experimental setting of cerebral ischemia-reperfusion. Substantial evidence of organ protection by noble gases exists in the field of cardioprotection. In the absence of evidence of neuroprotection by helium in human, further investigation is necessary. Our aim is to investigate the safety and feasibility of helium administration in patients with acute ischemic stroke, not eligible for trombolysis.
