The management of symptomatic cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH) can be often complicated by the presence of stunned myocardium and left ventricular failure. Vasopressors and inotropes are commonly used to optimize mean arterial pressure (MAP) and cerebral perfusion pressure (CPP). Intra-aortic balloon counterpulsation pump (IABP) may be indicated in the management of these patients. ⋯ Intra-aortic balloon counterpulsation pump (IABP) is used for hemodynamic support of patients in cardiogenic shock and its use in the setting of aSAH, cardiomyopathy, and cerebral vasospasm can be beneficial in preventing delayed ischemic deficits.

We sought to determine the effect of emergency department length of stay (ED-LOS) on outcomes in stroke patients admitted to the Neurological Intensive Care Unit (NICU). ⋯ Among critically ill stroke patients, ED-LOS > or =5 h before transfer to the NICU is independently associated with poor outcome at hospital discharge.

We have previously reported the association of hyperglycemia and mortality after ischemic stroke. This study attempts to answer the hypothesis, if hyperglycemia at arrival, is associated with early mortality and functional outcome in patients with acute non-traumatic intracerebral hemorrhage (ICH). ⋯ Hyperglycemia on presentation in non-diabetic patients is an independent predictor of early mortality and worse functional outcome in patients with intracerebral hemorrhage.

Comparative Study
"Optimal cerebral perfusion pressure" in poor grade patients after subarachnoid hemorrhage.
Cerebrovascular pressure reactivity depends on cerebral perfusion pressure (CPP), with the optimal CPP (CPPopt) defined as pressure at which cerebrovascular reactivity is functioning optimally, reaching minimal value of pressure reactivity index (PRx). The study investigates the association between vasospasm, PRx, and CPPopt in poor grade patients (WFNS 4&5) after subarachnoid hemorrhage (SAH). ⋯ Most WFNS 4&5 grade SAH patients with PRx below zero at optimal CPP during the first 48 h after ictus survived. Optimal CPP increases during vasospasm.

Ornithine transcarbamylase deficiency (OTCD) is the most common of the urea cycle disorders and results in an accumulation of ammonia and its metabolites. Excess ammonia in the brain is metabolized to glutamine, which increases intracellular osmolarity and contributes to cytotoxic edema. ⋯ Aggressive multimodality management of the patient coupled with bifrontal decompressive hemicraniectomy was a life-saving measure, offering the patient a reasonable outcome. At 6 month follow-up she had moderate disability on the Glasgow Outcome Score associated with cognitive difficulties.
