The purpose of this study was to determine the frequency of successful closed reduction (CR) of dislocated prosthetic hips performed by emergency physicians (EPs) as well as the incidence of acute complications. ⋯ EPs can safely and successfully perform CR on patients with dislocated total hip arthroplasties.

To compare a clinical decision rule (San Francisco Syncope Rule [SFSR]) and physician decision making when predicting serious outcomes in patients with syncope. ⋯ Physician judgment is good when predicting which patients with syncope will develop serious outcomes, but contrary to their judgment, physicians still admit a large number of low-risk patients. The SFSR performs better than current physician performance and has great potential to aid physician decision making.

Comparative Study Controlled Clinical Trial
Low plasma vasopressin/norepinephrine ratio predicts septic shock.
To evaluate if low plasma vasopressin and high norepinephrine concentrations predict grave prognosis of sepsis, a prospective sample of consecutive patients visiting the emergency department of a university teaching hospital who met the American College of Chest Physicians criteria of sepsis or severe sepsis was enrolled. Besides septic workup, we measured serum vasopressin and norepinephrine concentrations to correlate the impending outcome. One hundred eighty-two patients aged 27 to 99 years met the inclusive criteria and were classified as those with septic shock (n = 72), severe sepsis (n = 56), and those with sepsis only (n = 54) according to the outcome within 6 hours. ⋯ The mean interval between the time of samples drawn and the time of the most severe occurring sequelae was 2.4 +/- 0.8 hours. Receiver operating characteristic analysis revealed that the vasopressin/norepinephrine ratio 1 x 10(-3) had a sensitivity of 97% (95% CI, 90%-99%) and a specificity of 85% (95% CI, 78%-91%) for detecting impending septic shock. Low serum vasopressin/norepinephrine ratio can predict impending septic shock.

Schizophrenia is a common psychiatric condition, affecting approximately 1% of the population. Acute emergent presentations often include hallucinations, delusions, thought, and speech disorders. Agitation is common among emergency patients with schizophrenia. ⋯ Disposition decisions should be made based on the etiology of agitation, effective management, decisional capacity, and presence of suicidal or homicidal intentions. Many patients who have required nonpharmacological or pharmacological management of agitation require inpatient psychiatric treatment, either voluntarily or involuntarily. Psychiatric consultation should be sought for patients with schizophrenia and uncertain disposition determinations, or those requiring other complex management decisions.

Early detection of an inadvertent esophageal intubation can be particularly challenging in cases when the current standard of care, carbon dioxide detection, is unreliable. We sought to determine the sensitivity and specificity of an inexpensive and portable device, the gum elastic bougie (Eschmann Tracheal Tube Introducer, SIMS Portex, Inc, Keene, NH), as an endotracheal tube placement confirmation device. ⋯ In the cadaver model used in this study, the gum elastic bougie (Eschmann Tracheal Tube Introducer) shows promise as an endotracheal tube confirmation device.
