To determine the time between ambulance arrival at the scene to paramedic arrival at the patient (arrival to patient contact) and the effect of barriers to paramedic movement on this time interval. ⋯ The arrival-to-patient contact interval adds a variable and potentially lengthy amount of time to the total prehospital response time interval, and barriers impeding paramedic movement to the patient prolong this time interval. In 25% of all observed paramedic calls, the arrival-to-patient contact interval was more than four minutes. Measurement of the time from ambulance arrival on the scene to paramedic arrival at the patient is necessary to appropriately determine the relationship among total prehospital response time, paramedic interventions, and patient outcome.

To estimate the frequency of violence directed toward prehospital providers; to identify the methods used to manage violent patients in the prehospital setting; and to identify the educational, medical, and legal issues in the prehospital management of violent patients. ⋯ The potential for injury to prehospital providers from violent patients is probably widespread, and no mechanism for identifying injuries or exposure to violent patients currently exists. All systems should have protocols for managing violent patients and for restraint application. Educational sessions for self-defense and assessment of the scene for violence may be indicated.

Randomized Controlled Trial Clinical Trial
Atropine for the treatment of biliary tract pain: a double-blind, placebo-controlled trial.
To compare the efficacy of IM atropine with placebo for the treatment of pain caused by biliary tract disease. ⋯ Atropine is no better than placebo in the treatment of biliary tract pain.

The management of status epilepticus has improved over the past 20 years, resulting in a substantial decrease in the associated morbidity and mortality. Patients who have seizures that are refractory to initial pharmacologic interventions tend to have significant underlying toxic, metabolic, structural, or infectious disorders, and therefore management of refractory status epilepticus must focus on stabilization and on identification and correction of seizure etiology. Regardless of etiology, the faster the seizures are brought under control, the better the prognosis. ⋯ Benzodiazepines, phenytoin, and phenobarbital remain the most commonly used first- and second-line anticonvulsants, have proven effective in cases of status epilepticus, and should be administered within the first 45 minutes of management. For refractory status epilepticus, pentobarbital anesthesia is evolving as an effective and recommended treatment modality and should be instituted immediately after phenytoin and phenobarbital loading. The role of other anticonvulsants remains to be investigated in controlled clinical trials.

To evaluate the ability of paramedics in a nonurban emergency medical services system to use the Combitube, a combined endotracheal and esophageal obturator airway adjunct, in prehospital cardiac arrest patients. ⋯ Although visualized endotracheal intubation remains the preferred method of airway control, the Combitube may be an effective prehospital airway device as both a backup to the endotracheal tube and a primary airway. Although the Combitube does not require visualization with a laryngoscope, comprehensive training and continuing education are key factors affecting skill retention.
