Background: Oral anticoagulation (OAC) is a risk factor for intracerebral hemorrhage (ICH) which is an important source of disability and mortality. OAC-associated ICH (OAC-ICH) patients have worse outcomes as compared to ICH patients not on OAC, likely because of the associated larger stroke volumes, higher propensity to intraventricular hemorrhage, and a higher risk of rebleeding. Although current guidelines recommend that OAC should be reversed quickly, many health care systems have not developed a process for optimizing that aspect of care.

Background/purpose: Cardiac arrest is a common cause of death and neurological injury; therapeutic cooling for neuroprotection is standard of care. Despite numerous and ongoing trials targeting a specified cooling temperature for a target duration, the concept of temperature dose-the duration spent at a given depth of hypothermia-is not as well explored.

Methods: In this retrospective study, we examined 66 patients 18 years of age or older undergoing therapeutic hypothermia for cardiac arrest between 2007 and 2010 to assess the relationship of temperature dose with outcomes.

The AHA Guidelines recommend developing multi-tiered systems for the care of patients with acute stroke. An ideal stroke system of care should ensure that all patients receive the most efficient and timely care, regardless of how they first enter or access the medical care system. Coordination among the components of a stroke system is the most challenging but most essential aspect of any system of care.

There is no published literature regarding sub-Saharan health-care providers' understanding of stroke management patterns. Understanding current stroke management knowledge is important in formulating future education opportunities for providers to optimize patient outcomes. A cross-sectional survey of acute stroke diagnosis, hospital management, and secondary prevention questions was administered to health-care providers working in one large Kenyan acute referral hospital.

The sedation-assessment conundrum is the struggle to balance the need for sedation against the need to awaken the patient and perform a neurologic examination. This article discusses the nuances of the sedation-assessment conundrum as well as approaches to resolve this and reduce the negative impact of abruptly stopping sedative infusions. Both oversedation and undersedation affect critically ill patients.

As increasing numbers of elderly people undergo cardiac surgery, neurologists are frequently called upon to assess patients with neurological complications from the procedure. Some complications mandate acute intervention, whereas others need longer term observation and management. A large amount of published literature exists about these complications and guidance on best practice is constantly changing.

Object: Cerebral artery vasospasm is a major cause of death and disability in patients recovering from subarachnoid hemorrhage (SAH). Although the exact cause of vasospasm is unknown, one body of research suggests that clearing blood products by CSF drainage is associated with a lower frequency and severity of vasospasm. There are multiple approaches to facilitating CSF drainage, but there is inadequate evidence to determine the best practice.

Objectives: To review the available published literature to assess whether evidence supports a beneficial role for coordinated transition of care services for the postacute care of patients hospitalized with first or recurrent stroke or myocardial infarction (MI). This review was framed around five areas of investigation: (1) key components of transition of care services, (2) evidence for improvement in functional outcomes, morbidity, mortality, and quality of life, (3) associated risks or potential harms, (4) evidence for improvement in systems of care, and (5) evidence that benefits and harms vary by patient-based or system-based characteristics.

Data Sources: MEDLINE(®), CINAHL(®), Cochrane Database of Systematic Reviews, and Embase(®).

Background: A primary focus of hospital treatment following admission for subarachnoid haemorrhage (SAH) is a prevention of cerebral artery vasospasm, which may result in ischaemic stroke. Intraventricular catheter (IVC) insertion to facilitate cerebral spinal fluid (CSF) drainage and intracranial pressure (ICP) monitoring may reduce the incidence or severity of vasospasm, but insufficient evidence exists from which clinicians may determine the best practice of CSF management.

Aims: The aim of this study was to provide the pilot data to explore the impact of different methods of CSF drainage on outcomes in patients with SAH.

Background: Studies devoted to intensive glucose control suggested that the intensive insulin therapy (IIT) approach could effectively reduce complications associated with critical illness. A program of IIT with the goal of achieving a blood glucose of 80-120 mg/dL was, therefore, adopted in this study. To explore the impact of this approach in patients admitted to a neurocritical care unit, we compared the short-term outcomes of patients treated before and after our policy change.

A better prediction of the time course of symptomatic vasospasm (SVSP) might have a significant impact on the management and prevention of delayed neurologic ischemic deficit (DIND). We studied the influence of the treatment for ruptured aneurysm on SVSP timing. We retrospectively analyzed data of consecutive patients with aneurysmal subarachnoid hemorrhage (aSAH) admitted in our center between 1999 and 2005, treated within 72 hours of the rupture by surgical clipping or endovascular coiling and in accordance with our neuroscience unit protocol.

Background: Treatment of brain injury is often focused on minimizing intracranial pressure, which, when elevated, can lead to secondary brain injury. Chest percussion is a common practice used to treat and prevent pneumonia. Conflicting and limited anecdotal evidence indicates that physical stimulation increases intracranial pressure and should be avoided in patients at risk of intracranial hypertension.
