Subarachnoid hemorrhage from sudden gravitational changes.

Diffuse subarachnoid hemorrhage is commonly attributed to the rupture of intracranial aneurysms or other vascular malformations. Non-aneurysmal hemorrhages often have a characteristic pattern or clear mechanism (e.g.

Indicators of Subarachnoid Hemorrhage as a Cause of Sudden Cardiac Arrest.

Subarachnoid hemorrhage (SAH) may present with cardiac arrest (SAH-CA). We report a case of SAH-CA to assist providers in distinguishing SAH as an etiology of cardiac arrest despite electrocardiogram findings that may be suggestive of a cardiac etiology. SAH-CA is associated with high rates of return of spontaneous circulation, but overall poor outcome.

Multidisciplinary management and emerging therapeutic strategies in aneurysmal subarachnoid haemorrhage.

The management of patients with aneurysmal subarachnoid haemorrhage demands expertise to anticipate, recognise, and promptly treat the many neurological and systemic complications. For this reason, these patients are best cared for in high-volume medical centres with multidisciplinary teams and should preferably be treated in a specialised intensive care unit. Endovascular occlusion and surgical clipping provide complementary alternatives for the treatment of aneurysms.

Predictors of apnea test failure during brain death determination.

Background: In a recent publication (Wijdicks et al. in Neurology 71(16):1240, 2008), apnea test safety during brain death determination was evaluated at a single tertiary care center. One major conclusion was that apnea testing was safe in hemodynamically compromised patients in most circumstances and rarely aborted.
