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.

There is practice heterogeneity in the use, type, and duration of prophylactic antiseizure medications (ASM) in patients hospitalized with acute nontraumatic intracerebral hemorrhage (ICH). ⋯ We suggest avoidance of prophylactic ASM in hospitalized adult patients with acute nontraumatic ICH (weak recommendation, very low quality of evidence). If used, we suggest LEV over PHT/fPHT (weak recommendation, very low quality of evidence) for a short duration (≤ 7 days; weak recommendation, very low quality of evidence).

Point-of-care ultrasound (POCUS)/critical care ultrasound (CCU) use in medical and surgical intensive care units has surged over the last few decades. It is unclear if this has similarly translated in neurocritical care (NCC) units. We designed a survey to describe the current state of POCUS/CCU use and training among NCC providers. ⋯ This national survey indicated that POCUS/CCU is moderately used among NCC providers. However, more formalized and robust training in POCUS/CCU is needed for trainees and practitioners in NCC to enhance comfortability with using ultrasound for clinical assessments.
