Because the benefits from thrombolytic therapy in acute myocardial infarction (AMI) are time dependent, multiple strategies have been devised to speed therapy. This study sought to determine whether hospital-based nurse and paramedic advanced life support (ALS) providers could be trained to independently evaluate (sight read) a prehospital 12-lead electrocardiogram (ECG) for the presence of AMI as part of a protocol designed to speed in-hospital administration of thrombolytic agents. Providers were required to determine on the basis of a protocol (1) whether or not AMI was present, and (2) whether or not thrombolytic therapy was indicated. ⋯ Fourteen patients (9%) received thrombolytic therapy. In-hospital times to administration of thrombolytic therapy decreased to an average of 22 +/- 13.8 minutes in the studied group compared with a historical control group average of 51 +/- 50 minutes. It is concluded that hospital-based paramedics and nurses can successfully be taught to evaluate (ie, sight read) a prehospital ECG for the presence of AMI with accuracy.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this study was to develop a valid and reliable instrument to measure the job satisfaction of physicians practicing emergency medicine. A prospective survey involving four separate stages (an item evaluation and reduction stage, a factor analysis stage, a construct validity stage, and a reliability stage) was distributed in Canada to full-time emergency physicians. Three separate survey instruments were administered (an initial draft instrument with 228 items, a pilot instrument with 142 items, and the final instrument with 79 items). ⋯ Correlations between the final instrument and the CES-D scale, emotional exhaustion, and depersonalization subscales of the Maslach Burnout Inventory were negative. A test-retest reliability study on 42 physicians showed Pearson's correlation coefficients for individual domains were all greater than 0.7 and greater than 0.8 for the final instrument. This study has produced a valid and reliable instrument for measuring emergency physician job satisfaction, which is both internally consistent and stable.

Previous literature has identified uvulitis as a condition with serious implications. This report details a series of 15 patients with uvulitis whose clinical features were remarkable for a relatively benign course. This is the largest series of patients with uvulitis in the literature. ⋯ Of the 14 patients discharged, 13 (93%) were followed-up and none required further care. Seven (50%) of the discharged patients received symptomatic treatment only, whereas the others were treated with medications including antibiotics, corticosteroids, diphenhydramine, and B-agonists. Further research into the etiology and management of uvulitis is warranted.

Sodium bicarbonate is an extremely well-known agent that historically has been used for a variety of medical conditions. Despite the widespread use of oral bicarbonate, little documented toxicity has occurred, and the emergency medicine literature contains no reports of toxicity caused by the ingestion of baking soda. ⋯ The case of a patient with three hospital admissions in 4 months, all the result of excessive oral intake of bicarbonate for symptomatic relief of dyspepsia is reported. Evaluation and treatment of patients with acute bicarbonate ingestion is discussed.

To determine the clinical usefulness of infrared skin temperatures in diagnosing appendicitis, the authors conducted a prospective study of 86 adult and pediatric emergency department (ED) patients presenting during a 4-month study period with acute right lower abdominal pain. Skin temperature readings (FirstTemp digital thermometer, Intelligent Medical Systems, Inc, Carlsbad, CA) were taken from the right lower abdominal quadrant and a corresponding position on the left. An unpaired t test was used to determine if there was a significant difference between the right and left lower quadrants in patients with appendicitis. ⋯ There was no significant skin temperature differential between the lower abdominal quadrants in either patient group (0.0 degree C vs 0.1 degree C; P > .5). Three patients had a skin temperature on the right that was at least 1 degrees C warmer than on the left; none of these patients had appendicitis. The results suggest that infrared thermography is not a sensitive diagnostic test for acute appendicitis in the ED population.
