The objective of this study was to characterize the effect of intravenous hypertonic sodium bicarbonate (NaHCO3) administration in patients with moderate-to-severe cyclic antidepressant (CA) overdose. We reviewed charts of all 91 patients given the diagnosis of CA overdose in the University of California Los Angeles (UCLA) Emergency Medicine Center (EMC), who either died in the EMC or were admitted to the medical intensive care unit (MICU), and who received NaHCO3 in the EMC between 1980 and 1988. Twenty-four other patients with the same EMC diagnosis were admitted to the MICU during this period but did not receive NaHCO3. ⋯ No complications were attributable to the administration of NaHCO3. NaHCO3 seems to improve hypotension and normalize QRS duration rapidly in most patients treated, and improve mental status changes in almost one half. Serum alkalinization with NaHCO3, in conjunction with appropriate supportive care, seems to limit major morbidity and mortality effectively in patients with serious CA overdose.

Several management strategies for radiographic evaluation of head-injury patients have been developed, most are based on retrospective analysis. The study attempted to prospectively evaluate the previously published Masters' criteria defining low-, medium-, and high-yield patients. A community hospital emergency department with a low prevalence of serious head injury was studied, and 1,000 consecutive patients 2 years of age presenting with historical or physical evidence of blunt head trauma were asked to participate; 967 consented. ⋯ Of the 895, 71 patients (7.9%) did report receiving follow-up medical care for their head injury; none had evidence of missed intracranial injury requiring intervention. Therefore, it can be inferred with a 95% confidence interval that 0.4% or less of patients who were diagnosed as not having intracranial injuries requiring intervention may actually have such injuries. The application of Masters' management strategy in low-risk populations permits clinicians to safely reduce the number of radiographs ordered for patients with head injury.

The main objective of this study was to compare bedside sonographic detection of hemoperitoneum with diagnostic peritoneal lavage/laparotomy in the patient with blunt abdominal trauma. A retrospective review was conducted of all blunt trauma patients that underwent emergency department (bedside) sonography to rule out intraperitoneal hemorrhage at a level I trauma center in 1991 to 1992. Patients were included in the study population only if: (1) the results of the ultrasound examination were interpreted before any other diagnostic studies, and (2) a diagnostic peritoneal lavage (DPL) or laparotomy was performed. ⋯ Eleven patients (24%) in this population had either a positive DPL or laparotomy. The sensitivity, specificity, and accuracy of bedside sonography in identifying intraperitoneal hemorrhage was 81.8%, 93.9%, and 90.9%, respectively. The ultrasound study provided an answer in less than 1 minute in most patients.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this study was to describe individual and practice characteristics of Canadian emergency physicians, and to determine if these characteristics varied with geographic region, type of certification, or method of reimbursement. The study took place in emergency departments across Canada, and all full-time physicians with certification in emergency medicine, and a random sample of Canadian Association of Emergency Physician members without certification were surveyed with a 23-item questionnaire. Descriptive statistics on individual and practice characteristics were outcome measures. ⋯ There are significant differences by geographic region in gross annual salary (P < .00001), method of reimbursement (P < .00001), and independent hospital emergency department status (P < .00001). Fee-for-service reimbursement for clinical service provides a higher gross annual income than other methods (P = .028). Emergency medicine is an emerging clinical discipline with a strong academic focus.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
Tissue and organ procurement in the emergency department setting.
A retrospective chart review of all emergency department (ED) deaths in patients younger than 65 years in seven area hospitals was performed for the calendar year of 1990. The number and percentage of families approached and consenting to tissue donation among the various EDs was compared and reasons for not approaching families were evaluated for their validity. Procurement rates between the years 1990 and 1991 were compared for two area hospitals, which made a specified (nonmedical) service responsible for tissue requests in 1991. ⋯ Tissue procurement rates in EDs with procurement systems in place are low despite consent rates of those approached of 36%. The major contributing factor is the failure to request tissue from the families of eligible candidates even when there are no exclusion criteria met. Suburban EDs had a higher success rate than urban EDs.
