Patients experiencing apoplectic intracranial processes may develop neurogenic cardiomyopathy (NC). The purpose of this research is to determine whether cerebrospinal fluid (CSF) catecholamine levels are elevated in subarachnoid hemorrhage (SAH) patients with NC when compared to those without NC. ⋯ SAH patients with NC tend to have greater CSF catecholamine levels than those without NC. However, the development of NC may also be related to factors not evaluated by our study.

Review Meta Analysis
Locally-administered intrathecal thrombolytics following aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis.
The volume and clearance rate of blood in the basal cisterns and ventricles are important predictors of complications following aneurysmal subarachnoid hemorrhage (SAH). Thus, there is a strong rationale for interventions aimed at accelerating the clearance of blood. ⋯ Current data suggests that intrathecal thrombolytics improve outcomes following SAH. However, there are important limitations to existing RCTs, with considerable risk of bias. Further standardization of techniques and evaluation in larger, more rigorous RCTs is required.

As the practice of aggressive temperature control has become more commonplace, new clinical problems are arising, of which shivering is the most common. Treatment for shivering while avoiding the negative consequences of many anti-shivering therapies is often difficult. We have developed a stepwise protocol that emphasizes use of the least sedating regimen to achieve adequate shiver control. ⋯ A significant proportion of patients undergoing temperature modulation can be effectively treated for shivering without over-sedation and paralysis. Patients at higher risk for needing more interventions are younger men with decreased BSA.

Case Reports
Multimodal neuromonitoring in a patient with aneurysmal subarachnoid hemorrhage associated with aortic coarctation.
Aortic coarctation (AC) rarely remains undiagnosed until adulthood. Intracranial aneurysms and spontaneous subarachnoid hemorrhage (SAH) are more frequent in patients with AC than in the general population. ⋯ Cerebral aneurysm rupture associated with coarctation of the aorta is rare. The aim of this report is to call attention to AC in, particularly, young patients presenting with SAH and to discuss advanced multimodal neuromonitoring techniques used to optimize intensive care management.

Delirium is defined by a fluctuating level of attentiveness and has been associated with increased ICU mortality and poor cognitive outcomes in both general ICU and neurocritical care populations. Sedation use in the ICU can contribute to delirium. Limiting ICU sedation allows for the diagnosis of underlying acute neurological insults associated with delirium and leads to shorter mechanical ventilation time, shorter length of stay, and improved 1 year mortality rates. Identifying the underlying etiology of delirium is critical to developing treatment paradigms.
