Physician involvement in the provision of both direct and indirect medical control to emergency medical providers is critical to the effective operation of an emergency medical services (EMS) system. We conducted a survey of all accredited emergency medicine residency programs in the United States to determine the content of EMS instruction provided to these physicians-in-training. ⋯ The importance placed on EMS during residency training is variable. EMS is the domain of emergency medicine, and adequate training of residents for these responsibilities is imperative.

Randomized Controlled Trial Clinical Trial
Prophylactic penicillin for intraoral wounds.
We conducted a prospective, double-blind, placebo-controlled study in adult patients to determine whether prophylactic penicillin prevents infection in intraoral lacerations secondary to minor trauma or seizures. Uninfected full-thickness, mucosal-only, or through-and-through wounds presenting within 24 hours of injury were considered. Management consisted of cleansing, irrigation, debridement, and closure as indicated: no topical antibiotics were applied. ⋯ When patients poorly compliant with therapy were eliminated from analysis, none of the penicillin-treated patients and five of the placebo-treated patients developed infections (P = .027). Our data suggest that patients with intraoral wounds may benefit from prophylactic penicillin if compliant with their therapy. More studies are needed to further delineate the usefulness of prophylactic antibiotics for these wounds.

The survival rate for patients with prehospital cardiac arrest has improved in some communities with early defibrillation by emergency medical technician-defibrillators (EMT-Ds). In rural areas, previous studies on survival with defibrillation by EMT-Ds have been variable. We conducted an EMT-D study to determine effectiveness in various prehospital settings. ⋯ The neurologic status of survivors at time of hospital discharge was normal in 72%. The average response time, defined as time of emergency medical services activation to the time of EMT-D arrival, was 7.3 +/- 5.8 and 3.7 +/- 2.0 minutes for nonsurvivors and survivors, respectively (P less than .002). There were no survivors when the response time was more than eight minutes.(ABSTRACT TRUNCATED AT 250 WORDS)

Unstable injury of the cervical spine must be considered in all victims of blunt trauma. To evaluate the role of limited, directed computed tomography (CT) in the initial evaluation of the cervical spine, a one-year study involving 104 high-risk patients was undertaken. ⋯ All false-negative studies involved atlantoaxial rotary subluxation. We conclude that limited, directed CT of the cervical spine is appropriate in the initial evaluation of patients at risk, particularly if plain radiographs are inadequate, but is of limited value in the evaluation of ligamentous injury of the upper cervical spine.
