Randomized Controlled Trial
Assessment of Common Preoxygenation Strategies Outside of the Operating Room Environment.
Preoxygenation prior to intubation aims to increase the duration of safe apnea by causing denitrogenation of the functional residual capacity, replacing this volume with a reservoir of oxygen. In the operating room (OR) the criterion standard for preoxygenation is an anesthetic circuit and well-fitting face mask, which provide a high fractional inspired oxygen concentration (FiO2 ). Outside of the OR, various strategies exist to provide preoxygenation. The objective was to evaluate the effectiveness of commonly used preoxygenation strategies outside of the OR environment. ⋯ In healthy volunteers, the effectiveness of BVM preoxygenation was comparable to the anesthetic circuit (criterion standard) and superior to preoxygenation with NRM. The addition of NC oxygen, PEEP, or both did not improve the efficacy of the BVM device.

Observational Study
Patient-Reported Outcomes from A National, Prospective, Observational Study of Emergency Department Acute Pain Management with an Intranasal NSAID, Opioids or Both.
Patient compliance and satisfaction with analgesics prescribed after emergency department (ED) care for acute pain are poorly understood, largely because of the lack of direct patient follow-up with the ED provider. Our objective was to compare patient satisfaction with three analgesia regimens prescribed for post-ED care-a nasally administered nonsteroidal anti-inflammatory drug (NSAID), an opioid, or combination therapy-by collecting granular follow-up on analgesic use, pain scores, side effects, work activity levels, and overall satisfaction directly from patients. ⋯ Automated telephonic follow-up of ED patients prescribed short-term analgesia is feasible. Ketorolac-based analgesia after an ED visit for many acute pain syndromes was associated with favorable patient outcomes and higher satisfaction than opioid-based therapy. SPRIX, an NSAID that is not available over the counter and has a novel delivery approach, may be useful for short-term post-ED outpatient analgesia.

The emergency department (ED) is characterized by stressors (e.g., fatigue, stress, time pressure, and complex decision-making) that can pose challenges to delivering high-quality, equitable care. Although it has been suggested that characteristics of the ED may exacerbate reliance on cognitive heuristics, no research has directly investigated whether stressors in the ED impact physician racial bias, a common heuristic. We seek to determine if physicians have different levels of implicit racial bias post-ED shift versus preshift and to examine associations between demographics and cognitive stressors with bias. ⋯ While resident implicit bias remained stable overall preshift to postshift, cognitive stressors (overcrowding and patient load) were associated with increased implicit bias. Physicians in the ED should be aware of how cognitive stressors may exacerbate implicit racial bias.

Arachnoid cysts are abnormal intracranial fluid collections, and there is concern that these cysts may bleed or rupture following blunt head trauma. Our objective was to determine the risk of cyst-related complications in a cohort of children with arachnoid cysts who were evaluated for head trauma. ⋯ In this cohort of 68 children with arachnoid cysts who sustained head trauma, none demonstrated cyst-related bleeding or complications. This suggests the risk of arachnoid cyst-related complications in children following blunt head trauma is low and evaluation should align with existing clinical decision rules.

The presence of squamous epithelial cells (SECs) has been advocated to identify urinary contamination despite a paucity of evidence supporting this practice. We sought to determine the value of using quantitative SECs as a predictor of urinalysis contamination. ⋯ Squamous epithelial cells are a poor predictor of urine culture contamination, but may predict poor predictive performance of traditional urinalysis measures.
