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.

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.

Traumatic injuries to the cervical spine cause significant disability. Much of the morbidity and mortality that occurs in patients afflicted with cervical spinal cord injury (SCI) occurs early after injury due to primary neurologic dysfunction, systemic inflammation, concomitant injuries, treatments to prevent and ameliorate secondary insults, and prolonged immobilization. This study was undertaken to determine the incidence of organ dysfunction and failure using validated measures: the Multiple Organ Dysfunction Score (MODS) and the Sequential Organ Failure Assessment (SOFA). We also sought to determine if certain patient or injury characteristics were associated with the development of organ dysfunction and failure. ⋯ This study is the first to describe the incidence of organ dysfunction and failure in patients with isolated acute traumatic cervical SCI using validated organ system dysfunction scores. Respiratory, cardiovascular, neurologic, renal, hepatic, and hematologic dysfunction occurred commonly both on admission and over the ICU stay. Respiratory, cardiovascular, and neurologic failure were frequently found, while renal, hepatic, and hematologic failures were uncommon. Multiple organ failure occurred in the majority of patients. ASIA motor score and AIS were found to strongly correlate with the development of organ dysfunction and failure. Level of injury should be used with caution when describing the risk of complications and the need for medical interventions.
