Adjusted hypervolemic hemodilution in acute ischemic stroke.

Adjusted hypervolemic hemodilution in acute ischemic stroke.

We prospectively randomized 47 patients with acute ischemic stroke of the middle cerebral artery of less than 24 hours' duration to either adjusted hypervolemic hemodilution or control treatment and followed them up for 90 days. Rapid hemodilution to a target hematocrit of 30-35% as monitored with bedside determinations was achieved by using infusions of dextran 40, venesections, and infusions ...

Hypervolemic hemodilution in acute ischemic stroke: the Multicenter Austrian Hemodilution Stroke Trial (MAHST).

BACKGROUND AND PURPOSE Experimental studies suggest a beneficial effect of hemodilution on acute ischemic stroke. This was not proven by previous multicenter trials in the clinical setting. Various reasons have been suggested for the failure of these studies, which we attempted to consider in the Multicenter Austrian Hemodilution Stroke Trial (MAHST). METHODS MAHST is a randomized, double-bli...

Hemodilution for acute ischemic stroke.

schemic stroke involves focal hypoperfusion of the central nervous system. Hemodilution could theoretically improve perfusion to the affected area and, therefore, reduce infarct size. Objective To assess the effects of hemodilution on clinical outcomes in patients with acute ischemic stroke. We also searched trials registers, scanned reference lists, and contacted authors. We included random-iz...

Hypervolemic hemodilution treatment of acute stroke. Results of a randomized multicenter trial using pentastarch. The Hemodilution in Stroke Study Group.

Patients with acute ischemic stroke were randomized less than 24 hours after onset to standard (S) therapy (n = 43) or to hypervolemic hemodilution (HH) with pentastarch (n = 45). The therapeutic goal of hypervolemic hemodilution was to rapidly reduce hematocrit to 33%, to raise cardiac output, and to continue hypervolemic hemodilution for 3 days. A graded neurologic examination was scored by a...
