ReviewCritical care of intracerebral and subarachnoid hemorrhage.
The acute management of primary intracerebral or aneurysmal subarachnoid hemorrhage requires a comprehensive approach involving stabilization of the patient, surgical intervention, and continued intensive care treatment of medical and neurologic complications. The are several causes of intracerebral hemorrhage (ICH), including hypertension, cerebral amyloid angiopathy, sympathomimetic drugs, and coagulopathies. More recently, use of thrombolytic agents in the treatment of acute ischemic stroke has increased the risk of ICH. ⋯ Patients with aneurysmal subarachnoid hemorrhage may experience rebleeding, symptomatic vasospasm, or hydrocephalus. Medical management in the intensive care unit with careful attention to fluid and electrolyte balance, nutrition, cardiopulmonary monitoring, and close observation for changes in the neurologic exam is vital. This review examines the diagnosis and intensive care management of patients with intracerebral or subarachnoid hemorrhage, and reviews some of the newer therapies for treatment of these disorders.

Advances in neurologic therapeutics and intensive care medicine have expanded the arsenal of treatments available for the critical care of ischemic stroke. Several agents are available for acute reperfusion of the ischemic brain. These include intravenous recombinant tissue-plasminogen activator (rtPA), which is effective in a 3-hour time window, and intra-arterial thrombolytics, which may be effective within 6 hours. ⋯ Unfortunately, there is a critical lack of well-designed clinical studies to guide the clinician in the use of these interventions. In addition, there is concern that some of these interventions may preserve life at the cost of quality of life. This article reviews the evidence behind these approaches to the critical care of ischemic stroke.
