Critical Care for Patients with Massive Ischemic Stroke

Abstract

The authors have no financial conflicts of interest. Malignant cerebral edema following ischemic stroke is life threatening, as it can cause inad-equate blood flow and perfusion leading to irreversible tissue hypoxia and metabolic crisis. Increased intracranial pressure and brain shift can cause herniation syndrome and finally brain death. Multiple randomized clinical trials have shown that preemptive decompressive hemicraniectomy effectively reduces mortality and morbidity in patients with malignant middle cerebral artery infarction. Another life-saving decompressive surgery is suboccipital craniectomy for patients with brainstem compression by edematous cerebellar infarction. In addition to decompressive surgery, cerebrospinal fluid drainage by ventriculostomy should be considered for patients with acute hydrocephalus following stroke. Medical treatment begins with sedation, analgesia, and general measures including ventilatory support, head elevation, maintaining a neutral neck position, and avoiding conditions associated with in-tracranial hypertension. Optimization of cerebral perfusion pressure and reduction of intra-cranial pressure should always be pursued simultaneously. Osmotherapy with mannitol i
