Early recognition of traumatic brain injury (TBI) is important to facilitate time-sensitive care. Electroencephalography (EEG) can identify TBI, but feasibility of EEG has not been evaluated in prehospital settings. We tested the feasibility of obtaining single-channel EEG during air medical transport after trauma. We measured association between quantitative EEG features, early blood biomarkers, and abnormalities on head computerized tomography (CT). ⋯ Prehospital EEG acquisition is feasible during air transport after trauma.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated response to an infection that requires early intervention. Prehospital sepsis screening tools have not yet been widely evaluated for their performance in clinical practice. ⋯ Due to their relatively good predictive abilities to detect septic patients and simplicities, the PRESEP and Miami Sepsis Scores could be used for screening patients for sepsis in prehospital settings. Further prospective validation and evaluation of effect on clinical outcomes are needed.

Predictive Factors for the Application of Pelvic Binders in the Prehospital Setting.
Early pelvic binder placement in the field stabilizes pelvic fractures and tamponades potential hemorrhage within the pelvis. Despite known risk factors for pelvic fracture, it remains challenging to quickly triage and correctly apply a pelvic binder. We aim to develop a prediction model that exclusively uses prehospital criteria to inform the decision to place a pelvic binder. ⋯ Establishing select prehospital criteria for the empiric application of pelvic binders for patients in the field with blunt injuries, hemodynamic instability, frontal or side motor vehicle collision impact, and non-front seat passenger may improve outcomes among patients with pelvic fractures.

A Practical Solution for Preoxygenation in the Prehospital Setting: A Nonrebreather Mask with Flush Rate Oxygen.
Prehospital clinicians need a practical means of providing adequate preoxygenation prior to intubation. A bag-valve-mask (BVM) can be used for preoxygenation in perfect conditions but is likely to fail in emergency settings. For this reason, many airway experts have moved away from using BVM for preoxygenation and instead suggest using a nonrebreather (NRB) mask with flush rate oxygen.Literature on preoxygenation has suggested that a NRB mask delivering flush rate oxygen (on a 15 L/min O2 regulator, maximum flow, ∼50 L/min) is noninferior to BVM at 15 L/min held with a tight seal. However, in the prehospital setting, where emergency airway management success varies, preoxygenation techniques have not been deeply explored. Our study seeks to determine whether preoxygenation can be optimally performed with NRB at flush rate oxygen. ⋯ Among healthy volunteers, flush rate preoxygenation using NRB masks is noninferior to BVM using either a portable oxygen tank or ambulance oxygen. This is significant because preoxygenation using NRB masks with flush rate oxygen presents a simpler alternative to the use of BVMs. Preoxygenation using NRB masks at 25 L/min from a portable tank is inferior to BVM at flush rate.

The concept of early administration of P2Y12 inhibitor in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) is widely accepted, but whether prehospital administration results in greater coronary reperfusion remains unclear. Our study aims to analyze the benefit and safety of prehospital P2Y12 inhibitor compared to in-hospital P2Y12 inhibitor administration. ⋯ Prehospital P2Y12 inhibitor compared to in-hospital P2Y12 inhibitor is associated with a significantly higher rate of pre-PCI and post-PCI TIMI flow grade 2-3, a reduced risk of recurrent MI, and no increase in major bleeding in STEMI patients undergoing primary PCI.
