Review Multicenter Study
Rapid sequence intubation in adults with elevated intracranial pressure: a survey of emergency medicine residency programs.
A questionnaire entitled "Survey of Protocols for Rapid Sequence Intubation in Previously Healthy Adults with Elevated Intracranial Pressure" was distributed to the program directors of all 100 emergency medicine residency programs listed in the Directory of Graduate Medical Education Programs in February 1995. The medical literature on rapid sequence intubation in patients with suspected intracranial pressure elevations was reviewed. The findings of the review were compared with the survey responses. ⋯ Most of these programs follow the guidelines recommended in the medical literature. The majority of these guidelines, however, are based on statistical data performed in the laboratory or nonemergency environments. Further clinical studies in an emergency medicine environment must be performed to determine the optimal drug regimen for rapid sequence intubation in patients with elevated intracranial pressure.

Multicenter Study
Photograph documentation of motor vehicle damage by EMTs at the scene: a prospective multicenter study in the United States.
The purpose of this study was to determine if emergency medical service (EMS) personnel could take instant photographs of motor vehicle damage at crash scenes depicting the area and severity of damage of the crash under adverse weather conditions, in different lighting, and quickly enough so as not to interfere with patient care. This prospective multicenter trial involved 35 ambulances responding to motor vehicle crash scenes in rural, suburban, and urban areas in five centers in four states. Emergency medical technicians (EMTs) reported their experience implementing a protocol for use of an instant camera to photograph vehicle damage at crash scenes. ⋯ From one EMS agency in the study, 48 scene times during which photographs were taken were, on average, 1.5 minutes shorter than 48 scene times immediately before implementation of on-scene crash photography. Photographs were taken in different weather and lighting conditions. EMTs reported they were able to determine both area and severity of damage in 260 of 290 (92.5%) crash photographs, but they were unable to determine area and severity of damage in only 2 of 290 (0.7%) crash photographs.

Multicenter Study
Use of physician extenders and fast tracks in United States emergency departments.
To describe current practice regarding the use of physician extenders (PEs) and the "fast track" (FT) concept in United States emergency departments (EDs), a telephone survey of 250 US health care facilities offering emergency services was conducted. Of the EDs surveyed, 21.6% were using PEs at the time of the survey, and of those not using PEs, 23.5% intended to do so within the next 2 years. Those using PEs had been using them for a mean duration of 3.5 years (the mode was 2 years). ⋯ The mean estimated percentage of ED patients going through FT was 30.1%. The mean number of hours per day of FT operation was 13.4 hours on weekdays and 13.7 hours on weekends (the mode was 12 hours/day both on weekdays and weekends). Of hospitals using PEs in the ED, 56.0% had FT; of hospitals without PEs in the ED, 23.5% had FT.

Randomized Controlled Trial Multicenter Study Clinical Trial
The use of cytosolic enzyme increase in cerebrospinal fluid of patients resuscitated after cardiac arrest. Brain Resuscitation Clinical Trial I Study Group.
Levels of brain creatine phosphokinase (CPK), glutamic oxalic transaminase, lactate dehydrogenase, and lactate in lumbar cerebrospinal fluid (CSF) were analyzed as an adjunctive study in a randomized clinical trial evaluating the effects of thiopental loading intravenously in comatose survivors of cardiac arrest. Three hospitals participated and a total of 62 cases of enzyme changes were studied. ⋯ There was a significant negative correlation between cerebral recovery and increased CPK levels at 24 hours (P < .05), and a highly significant correlation with all three enzyme levels at 48 hours (P < .0001). The increase of cytosolic enzyme activity in lumbar CSF reflects permanent brain damage, and there is a relationship between activity levels and cerebral outcome.

Multicenter Study Comparative Study Clinical Trial Controlled Clinical Trial
Concomitant administration of antiemetics is not necessary with intramuscular dihydroergotamine.
The influence of concomitant administration of an antiemetic agent on the course of nausea was assessed in a field trial of intramuscular dihydroergotamine for the treatment of acute migraine. Of 311 migraine patients enrolled onto the study, 62% (191 of 311) experienced nausea at the outset; 38% (119 of 311) did not. Of those with nausea at the outset, 54% (103 of 191) received an antiemetic. ⋯ At the 30-minute point, 35% (61 of 173) of patients who received dihydroergotamine alone still experienced nausea versus 47% (62 of 133) of patients who received an antiemetic. At the 60-minute point, only 24% (42 of 174) of those given dihydroergotamine alone had nausea, compared with 38% (50 of 132) given concomitant antiemetic. Ongoing nausea seems to be a manifestation of the migraine process rather than an adverse effect associated with intramuscular dihydroergotamine.(ABSTRACT TRUNCATED AT 250 WORDS)
