Review Meta AnalysisThrombolysis for aneurysmal subarachnoid haemorrhage.
Aneurysmal subarachnoid haemorrhage continues to cause a significant burden of morbidity and mortality despite advances in care. Trials investigating local administration of thrombolytics have reported promising results. ⋯ There is some evidence that thrombolysis can probably improve outcomes after aneurysmal subarachnoid haemorrhage, without increasing the risk of haemorrhagic complications. Thrombolysis likely reduces the risk of poor functional outcome and cerebral artery vasospasm, and may reduce the risk of delayed cerebral ischaemia, but it likely makes little to no difference to case fatality or hydrocephalus, and may make little to no difference to the risk of cerebral infarction. However, the current evidence is still uncertain. The uncertainty is primarily due to the small total number of participants and outcome events. Data from further studies are required to confirm the efficacy of thrombolysis for improving outcomes after aneurysmal subarachnoid haemorrhage.

Intrathecal nicardipine (ITN) is an investigational therapy for cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH). The objective of this scoping review was to characterize the current state of the literature and map the current available evidence, examine research methodology, clarify key concepts and definitions in the literature, report procedural characteristics, identify and analyze knowledge gaps, and serve as a precursor for future systematic reviews, meta-analyses, and randomized controlled trials. An electronic search for studies on ITN for the treatment of CVS and DCI in patients with aSAH was conducted in accordance with published standards. ⋯ Study designs, drug administration, dosing regimens, drug concentrations, pharmacokinetics, patient selection, duration of therapy, outcome measures, adverse event monitoring, and definitions of CVS and DCI used are synthesized and discussed. Despite advances in the care of patients with aSAH, CVS and DCI remain leading causes of morbidity and mortality, and ITN represents a potential therapy to help prevent and treat this disease process. With one published randomized controlled trial on one method of administration, one trial underway on a second method of administration, and numerous heterogeneous and primarily retrospective studies published to date, future study with an emphasis on homogenizing study design and outcomes measured is needed to better understand this potential therapy.

The impact of statin pretreatment on outcomes for patients undergoing endovascular treatment of intracranial aneurysms remains uncertain. We aimed to conduct a systematic review and meta-analysis evaluating the efficacy and safety of statins in this population. ⋯ Statin pretreatment may decrease the risk of hemorrhagic complications and in-stent stenosis after endovascular aneurysm therapy but does not improve angiographic occlusion. An increased hazard of ischemic events was found. Further data are needed to validate these findings and clarify the role of statins in patients with aneurysms undergoing endovascular procedures.

Cerebral vasospasm (CV) following subarachnoid hemorrhage (SAH) remains one of the leading causes of high mortality and poor outcomes. Understanding the risk factors associated with CV is pivotal to improving patients' outcomes. We conducted an extensive search for analytical observational studies that analyzed the correlation between various variables and the likelihood of CV development among adult patients with SAH (age ≥ 18 years). Five scholar databases were used, namely, PubMed, EBSCO, Web of Science, Science Direct, and Google Scholar. ⋯ Overall, this systemic review provides a comprehensive summary of the current data that evaluates the potential risk factors for the development of CV after SAH. However, because of data heterogeneity, certain factors require further validation in their correlation with CV development. Larger-scale observational and clinical trials are mandatory to extensively investigate the significant predictors of CV to lay the scientific foundation for improving outcomes in susceptible patients with SAH.

ReviewHeadache Management in the Neuroscience Intensive Care Unit.
Headache is a common symptom in the Neuroscience Intensive Care Unit (NeuroICU). Our goal is to provide an overview of approaches to headache management for common neurocritical care conditions. ⋯ Headache disorders afflict nearly half of patients admitted to the NICU. Commonly encountered disorders featuring headache include cerebrovascular disease, trauma, and intracranial infection. Approaches to pain are highly variable, and multimodal pain regimens are commonly employed. The overall body of evidence supporting therapeutic strategies to manage headache in the critical care setting is slim, and pain control remains suboptimal in many cases with persistent reliance on opioids. Headache is a complex, frequently occurring phenomenon in the NeuroICU care setting. At present, literature on evidence-based practice for management of headache in the critical care setting remains scarce, and despite multimodal approaches, reliance on opioids is commonplace.
