Traditionally, the autopsy is viewed as the ultimate quality assurance indicator in clinical medicine, yet very few clinical departments actually incorporate autopsy results in their formal quality assurance plans. Consequently, to investigate how autopsy results can be included on our emergency department plan, the clinical and autopsy diagnoses of 244 patients were reviewed retrospectively and compared to identify conditions that were unapparent or misdiagnosed at the time of death. The study period was from January 1984 through June 1988. ⋯ The results clearly identify unexpected findings and point to the need for more aggressive evaluations of certain conditions. Systematic review of autopsy data as presented has led to meaningful changes and delivery of care to emergency patients. Autopsies are a vital source of outcome-based information that should be part of every ED's quality assurance and risk management plan.

Case Reports
Stress fracture of the first rib from serratus anterior tension: an unusual mechanism of injury.
Fracture of the first rib usually results from high-impact, direct trauma. Stress fractures are less common and are associated with minimal morbidity. The case of a patient with a stress fracture resulting from the use of an exercise machine is reported. ⋯ A new pathophysiologic mechanism involving the serratus anterior muscle is introduced and is supported by T2 relaxation times from magnetic resonance imaging. Stress and fatigue fractures of the first rib have minimal complications. An aggressive diagnostic evaluation of first rib fractures occurring by this mechanism is not warranted.

Fiberoptic-aided endotracheal intubation has been shown to be effective in difficult intubation secondary to anatomic abnormalities and traumatic conditions. A retrospective review of emergency airway management in an emergency department during a 30-month period found 35 patients who underwent fiberoptic-aided endotracheal intubation; 31 were treated for medical conditions, and four were trauma patients. Indications in the medical group included failed nasotracheal intubation (ten), anatomic abnormalities (six), and the initial airway maneuver attempted (15). ⋯ At our institution, the financial commitment has been approximately +17,000 during the past nine years. Repair or replacement of broken equipment appears to be necessary every two or three years. Immediate airway control is often difficult with fiberoptic-aided endotracheal intubation and should be used only in selected patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
Effect of epinephrine on end-tidal carbon dioxide monitoring during CPR.
End-tidal carbon dioxide (ETCO2) has been shown to correlate with coronary perfusion pressure (CPP) during CPR and has been proposed as a useful noninvasive monitor of CPR efficacy. The effects of therapeutic epinephrine dosing on ETCO2 and CPP in six dogs were examined. Ventricular fibrillation was induced and left untreated for five minutes before CPR was initiated. ⋯ There was a significant increase in CPP from 12.2 +/- 9.6 to 26.8 +/- 7.1 mm Hg (P = .006) after epinephrine. This was accompanied by a significant decrease in ETCO2 from 8.2 +/- 2.9 to 3.8 +/- 2.0 mm Hg (P = .01). These data indicate that after epinephrine administration, caution must be exercised in using ETCO2 as an indicator of CPP.
