Hemodilution in acute stroke.

Hemodilution in acute stroke.

IT SEEMS APPROPRIATE to attempt to improve ce-rebral blood flow (CBF) in stroke. By so doing, oxygen delivery to the brain will increase and removal of the waste products of metabolism will be more efficient. Better flow should also increase the fragmentation and dispersal of existing thrombi and inhibit extension and spread of intravascular thrombosis. One approach to increase CBF is to improv...

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...

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...
