What is the most powerful treatment for ischemic stroke?
The main treatment for ischemic stroke is intravenous tissue plasminogen activator (tPA), which breaks up clots. 2018 guidelines from the American Heart Association (AHA) and the American Stroke Association (ASA) state that tPA is most effective when it's given within four and a half hours from the start of a stroke.
Which drug class is most commonly used in the treatment of a stroke?
tPA (tissue plasminogen activator) Thrombolytic drugs such as tPA are often called clot busters. tPA is short for tissue plasminogen activator and can only be given to patients who are having a stroke caused by a blood clot (ischemic stroke). It can stop a stroke by breaking up the blood clot.
What is acute stroke intervention?

What is decompression surgery?
Decompressive surgery involves removal of a large part of the hemi-cranium to allow space for expansion of edematous brain tissue. The rationale of decompressive surgery is to allow expansion of edematous brain tissue to reduce intracranial pressure and prevent fatal brain herniation, increase perfusion pressure to the brain that is still salvageable, and preserve cerebral blood flow by preventing further compression of the collateral vessels. In prospective case series, surgical decompressive therapy in a hemispheric space-occupying infarction lowers the mortality rate from 80% to 30% without increasing the rate of severely disabled survivors as compared with historical controls. 7,9 An ongoing pilot prospective, multicenter National Institute of Neurological Disorders and Stroke (NINDS)-funded study HEmicraniectomy And Durotomy for Deterioration From Infarction Relating Swelling Trial (HEADDFIRST) is designed to test the hypothesis that this approach improves patient outcome among patients with large cerebral infarctions.
What is stroke treatment?
General stroke treatment is the treatment of general physiological conditions that need to be optimized in the setting of an acute stroke.

What is the effect of intravenous mannitol on the brain?
Intravenous infusion of substances that increase osmolality of blood create an osmotic gradient across the blood brain barrier. After this gradient, water is removed from the brain. An intact blood brain barrier is essential for this mechanism. Otherwise, the infused substance may enter brain parenchyma and may result in a rebound phenomenon if the infusion of osmotherapeutics is abruptly discontinued. Osmotic agents that are most frequently used and have been best investigated include intravenous mannitol and intravenous or enterally administered glycerol. Volume overload, hemolysis, lactic acidosis, and electrolyte disturbances are problems encountered with glycerol-based osmotherapy. During glycerol treatment, glucose infusions should be reduced. Both renal function and central venous pressure must be watched carefully in patients with underlying cardiac disease.
How do barbiturates decrease ICP?
Intravenous barbiturates (eg, pentobarbital or thiopental) can decrease ICP by lowering cerebral blood volume. Frequently, a parallel decrease in mean arterial pressure leads to a decrease in cerebral perfusion pressure. Therefore, an effective therapy with barbiturates depends on a reliable on-line monitoring of ICP and mean arterial pressure. During the injection of barbiturates, it is recommended that an ECG be recorded with superficial adhesive skull electrodes. The injection of barbiturates is stopped when a burst-suppression pattern is reached. Barbiturates work for a short period. Once the vasoconstriction effect is exhausted, no further lowering of ICP can be expected.

What is the goal of ischemic stroke?
The central goal of therapy in acute ischemic stroke is to preserve tissue in the ischemic penumbra, where perfusion is decreased but sufficient to stave off infarction. Tissue in this area of oligemia can be preserved by restoring blood flow to the compromised area and optimizing collateral flow.
