There are several situations in Emergency Medicine when it is desirable to promote a prompt diuresis to fill the bladder or obtain urine for diagnostic tests. We attempted to determine which of 3 commonly used intravenous solutions is most effective in establishing urine flow. In a prospective, randomized double-blind crossover study of 12 healthy male volunteers, we rapidly infused 20 cc/kg of D5W, D51/2NS, or 1/2NS immediately after voiding. Voided urine volumes were then recorded at 30, 60, 90, and 120 min postinfusion and the degree of glycosuria, if any, was noted. Total mean urine volume after D5W was 1181 ml, significantly greater than after 1/2NS (825 ml) and 1/2NS (630 ml), which did not differ between each other. Mean urine volume was greater at every time interval for the D5W group, and glycosuria was common in both D5-containing groups. We conclude that in healthy subjects, D5W is more effective in promoting rapid diuresis than are sodium-containing solutions.

Does wearing a necktie influence patient perceptions of emergency department care?

We conducted a prospective study of discharged emergency department (ED) patients to determine the effect of wearing a necktie by emergency physicians (EPs) had on patients' impression of their medical care. All male EPs were assigned randomly by dates to wear a necktie or no necktie, and the attire worn was otherwise similar in all respects. The study was conducted at a community teaching hospital with an Emergency Medicine residency and an annual census of 40,000. A total of 316 patients were surveyed. There were no statistically significant differences between patient groups in any of the five areas surveyed, including patient perception of physicians' appearance. Nearly 30% of patients incorrectly identified their doctor as wearing a necktie when no necktie was worn, and the perception of tie wearing was correlated with a positive impression of physician appearance. Wearing or not wearing a necktie did not significantly affect patients' impression of their physician or the care they received. However, patients seemingly preferred the appearance of physicians who were perceived to wear neckties.

Localization of steady currents in the lens.

Steady currents around the rat lens were measured with a vibrating probe. Inward currents were found at the anterior pole and to a lesser degree at the posterior pole. Outward currents were localized at the equator. These currents were inhibited and even reversed by high concentrations of potassium. Ouabain blocked currents after 24 hrs but not after 6 hrs of exposure. The composition of the medium was not critical. For example, currents were observed in NaCl and in MgSO4 solutions.
