The study was conducted to determine whether the use of prehospital instant photography of motor vehicle crashes (MVCs) by paramedics altered receiving physician (RP) perception of the magnitude of crash severity, as compared with verbal reports of vehicle damage. In addition, the study sought to determine whether altered RP perception resulted in any subsequent changes in emergency department (ED) management. ⋯ The augmentation of verbal paramedic reports with prehospital instant photographs frequently altered both physician perception of MVC severity and subsequent ED management of these trauma patients. However, cost to the patient and length of hospital stay were not significantly altered as a result of the change in physician perception.

The American Heart Association (AHA) currently recommends two-finger (TF) chest compression for infants. A previous study demonstrated that two-thumb (TT) with lateral chest wall compression provided significantly higher arterial pressures than did the TF method. Limitations of that study included the lack of an asphyxial model and non-standardized compression forces. ⋯ The TT method produced significantly higher SBPs. The authors were unable to demonstrate that the increased SBPs were secondary to the thoracic compression component because the rescuers did not reach the predetermined SCF in the TF groups. In this swine model of infant CPR, TT chest compression is an easier and more effective method.

Comparative Study
Influence of demographic variables in prehospital treatment of patients with chest pain.
To determine whether the number of interventions requested by EMS personnel for patients with acute, nontraumatic chest pain varied with the patient's gender or race. ⋯ Among older patients and among young females, EMS personnel requested similar numbers of interventions for patient complaining of acute, nontraumatic chest pain regardless of patients race. Patterns of care appeared to differ for young males, a finding that warrants further study.

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.
