Case Reports
Right pneumothorax with the S1Q3T3 electrocardiogram pattern usually associated with pulmonary embolus.
An 18-year-old man presented with a spontaneous right pneumothorax. An initial electrocardiogram (ECG) showed an S wave in lead I, a Q wave in lead III, and an inverted T wave in lead III. ⋯ Both right and left pneumothorax have been associated with ECG changes, including changes that mimic myocardial ischemia. Because the clinical presentation of pneumothorax may be similar to angina or pulmonary embolus, ECG changes with pneumothorax may lead to confusion in the diagnosis.

A retrospective review of the medical records of blunt trauma patients with sternal fracture admitted to a level 1 trauma center from June 1990 to June 1993 was undertaken to determine the relationship between sternal fractures and clinically significant myocardial injury, and to assess the usefulness of cardiac evaluation and monitoring in these patients. Of 33 patients with sternal fracture, 31 were in motor vehicle crashes and 2 were pedestrians struck. All had Glasgow Coma Scale score = 15. ⋯ No CPK-MB fraction was >5%. These results show that sternal fracture is not a marker for clinically significant myocardial injury. The management of sternal fracture patients should be directed toward the treatment of associated injuries.

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.
