Impact of Surgical Team Involvement at the Time of Trauma Activation for Pediatric Patients With Motorized Cycle or All-Terrain Vehicle Injury Mechanism.
At our institution, level 2 trauma (L2T) activations are primarily managed by pediatric emergency medicine (PEM) physicians, whereas level 1 activations are co-managed by pediatric surgery and PEM. Starting in September 2019, the response to L2T activations due to all-terrain vehicles or motorized cycles (ATVs/MCs) changed to include surgical assessment upon patient arrival due to increased likelihood of significant injuries and need for higher level of care. The impact of PEM/surgery co-management of ATV/MC L2T patients on time to an admission decision is unknown. ⋯ Early surgical assessment for pediatric patients with ATV/MC injuries improved time to an admission decision and trauma communication huddle compliance. Next steps include identifying process improvement opportunities to decrease ED total length of stay for patients with ATV/MC injuries.

Background : Trauma and blood loss are frequently associated with organ failure, immune dysfunction, and a high risk of secondary bacterial lung infections. We aim to test if plasma metabolomic flux and monocyte bioenergetics are altered in association with trauma and related secondary infections. Methods : Plasma samples were collected from trauma patients at three time points: days 0, 3, and 7 postadmission. ⋯ Conclusions : Our study highlights that the metabolic profile is significantly and persistently affected by trauma and related infections. Among trauma survivors, metabolic alterations in plasma were associated with reduced monocyte bioenergetics. These exploratory findings establish a groundwork for future clinical studies aimed at enhancing our understanding of the interplay between metabolic/bioenergetic alterations associated with trauma and secondary bacterial infections.

As e-scooters have become common modes of transportations in urban environments, riding e-scooters has become a common mechanism of injury. This study examines the relationship between when riders are using these devices (i.e. day of week, and time of the day) and injury incidence based on data from a large U.S. city. ⋯ E-Scooter injury incidence varies by the time of day. The time of day in which a person rides an e-scooter can have a significant impact on the likelihood that the person will sustain an injury.

Patients with traumatic out-of-hospital cardiac arrest (t-OHCA) require on-scene airway management to maintain tissue oxygenation. However, the benefits of prehospital endotracheal intubation remain unclear, particularly regarding neurological outcomes. Therefore, this study aimed to evaluate the association between prehospital intubation and favourable neurological outcomes in patients with t-OHCA. ⋯ Prehospital intubation was associated with favourable neurological outcomes among adult patients with t-OHCA who had severe chest injury or transportation time >15 min.

Objective : Vascular endothelial cells (ECs) sense and respond to both trauma factors (histone proteins) and sepsis signals (bacterial lipopolysaccharide, LPS) with elevations in calcium (Ca 2+ ), but it is not clear if the patterns of activation are similar or different. We hypothesized that within seconds of exposure, histones but not LPS would produce a large EC Ca 2+ response. We also hypothesized that histones would produce different spatio-temporal patterns of Ca 2+ events in veins than in arteries. ⋯ Exposure of ECs to histones or LPS both increased gene expression, but different mRNAs were induced. Conclusions : LPS and histones activate ECs through mechanisms that are distinct and additive; only histones produce large aberrant Ca 2+ events. ECs in arteries and veins display different patterns of Ca 2+ responses to histones.
