Randomized Controlled Trial Clinical Trial
The effects of neutral positioning with and without padding on spinal immobilization of healthy subjects.
To compare the incidences and severities of pain experienced by healthy volunteers undergoing spinal immobilization in the neutral position with and without occipital padding. To compare the incidence of pain when immobilized in the neutral position with the incidence in a nonneutral position. ⋯ Pain is frequently reported by healthy volunteers following spinal immobilization. Occipital padding does not appear to significantly decrease the incidence or severity of pain. Alignment of the cervical spine in the neutral position may reduce the incidence of pain, but further studies should be conducted to substantiate this observation.

Randomized Controlled Trial Comparative Study Clinical Trial
A new method for rapid fluid bolus infusion into a peripheral vein.
To compare the flow rates achieved by a new short-tubed infusion device with those obtained with a conventional apparatus, using gravity, manual pressure, and pneumatic inflation as the driving forces. ⋯ Flow of crystalloid under pressure into a peripheral vein is markedly increased with the new STP setup as compared with the CON setup. Incorporation of this new setup in prehospital care would allow EMS personnel to infuse fluid more rapidly and conveniently during transport.

Randomized Controlled Trial Clinical Trial
A randomized, controlled trial of the efficacy of closed chest compressions in ambulances.
To examine the feasibility of closed chest compressions in ambulances. ⋯ The percentage of correct compressions in all the vehicles tested was lower when compared with the percentage on the ground, and the increase in heart rate was higher. Only one of these results was statistically significant. A further study with more participants seems warranted.

Randomized Controlled Trial Comparative Study Clinical Trial
Paramedic evaluation of clinical indicators of cervical spinal injury.
Standard prehospital practice includes frequent immobilization of blunt trauma patients, oftentimes based solely on mechanism. Unnecessary cervical spine (c-spine) immobilization does have disadvantages, including morbidity such as low back pain and splinting, increased scene time and costs, and patient-paramedic conflict. Some emergency physicians (EPs) use clinical criteria to clear trauma patients of c-spine injury. If paramedics were able to apply clinical criteria in the out-of-hospital setting, then unnecessary c-spine immobilization could be safely avoided. The authors designed a prospective, randomized, simulated trial to determine the level of agreement between paramedic and EP assessments of clinical indicators of c-spine injury, hypothesizing that there would be substantial agreement between them. ⋯ In this model, there was excellent agreement between paramedics and physicians when evaluating simulated patients for possible c-spine injury. No patient requiring immobilization would have been clinically cleared by paramedics. These data support the progression to a prospective field trial evaluating the use of these criteria by paramedics.

Randomized Controlled Trial Comparative Study Clinical Trial
The PTL, Combitube, laryngeal mask, and oral airway: a randomized prehospital comparative study of ventilatory device effectiveness and cost-effectiveness in 470 cases of cardiorespiratory arrest.
A prehospital study was conducted to assess and compare three alternative airway devices and the oral airway for use by non-Advanced Life Support emergency medical assistants (EMAs). ⋯ The PTL, LM, and Combi appear to offer substantial advances over the OA/BVM system. Although the most costly, the Combitube was associated with the least problems with ventilation and was the most preferred by a majority of EMAs.
