Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other interventions - Head Position

Experimental: lying flat head position - positioning the head of the bed at zero degrees during the first 48 hours from admission of patients with acute ischemic stroke Active Comparator: upright position of the head of the bed during 48 hours from admission of patients with acute ischemic stroke


Other interventions: Head Position
Head position during the first 48 hours from admission of patients with acute ischemic stroke.

This trial is organized as a cluster randomised trial to a policy of flat head position or upright head position. Clusters will be months, so that all patients admitted during a given month will be positioned either in the flat down head position (intervention) or upright head position (control). This will allow health teams to follow a monthly protocol without changing position between patients.
