The window for acute ischemic stroke treatment was previously limited to 4.5 hours for intravenous tissue plasminogen activator and to 6 hours for thrombectomy. Recent studies using advanced imaging selection expand this window for select patients up to 24 hours from last known well. ⋯ It analyzes the implications on prehospital protocols to identify and transfer large-vessel occlusion stroke patients, on issues of distributive justice, and on ED management to provide advanced imaging and access to thrombectomy centers. The creation of high-performing systems of care to manage acute ischemic stroke patients requires academic emergency physician leadership attentive to the rapidly changing science of stroke care.

"Full Stomach" Despite the Wait: Point-of-Care Gastric Ultrasound at the Time of Procedural Sedation in the Pediatric Emergency Department.
The objective was to use gastric point-of-care ultrasound (POCUS) to assess gastric contents and volume, summarize the prevalence of "full stomach," and explore the relationship between fasting time and gastric contents at the time of procedural sedation. ⋯ Gastric POCUS classified many patients as having a full stomach at the time of expected procedural sedation, despite prolonged fasting times. These findings may inform risk-benefit considerations when planning the timing and medication choice for procedural sedation.

While immediate diagnosis and irrigation is standard chemical eye burn practice, it is unknown to what extent specific pH measurements influence management, given the frequent clinical availability of narrow-spectrum nitrazine pH strips. We hypothesize that exclusive broad-spectrum pH strip implementation leads to more accurate measurement and expedited ophthalmologic consultation. ⋯ Exclusive non-obstetric implementation of broad-spectrum pH strips may allow greater accuracy and faster management of ocular chemical burns. Availability of narrow-spectrum pH strips may be dangerous clinically by falsely reassuring the examiner with inherent inaccuracy.
