Comparative Study Clinical Trial Controlled Clinical Trial
A comparison of two automated external defibrillator algorithms.
To compare the interval to delivery of the first shock by first responders in mannequin-based cardiac arrest scenarios using two automated external defibrillator (AED) algorithms. ⋯ A-II reduced the interval from mannequin contact to the first shock in standard training scenarios.

Adrenal failure, a treatable condition, can have catastrophic consequences if unrecognized in critically ill ED patients. The authors' objective was to prospectively study adrenal function in a case series of hemodynamically unstable (high-risk) patients from a large, urban ED over a 12-month period. ⋯ Adrenal dysfunction is common in high-risk ED patients. Overall, it has a frequency of 19% among a homogeneous population of hemodynamically unstable vasopressor-dependent patients. The effect of physiologic glucocorticoid replacement in this setting remains to be determined.

To investigate out-of-hospital ventricular tachycardia (VT) cardiac arrest patients, comparing the prevalences and outcomes of the following VT subtypes among this population: monomorphic VT (MVT), polymorphic VT (PVT), and torsades de pointes (TdP, PVT with a prolonged QT interval). ⋯ In this population of out-of-hospital VT arrest patients, MVT is the most common form of VT encountered; PVT and the subtype TdP are also seen in this population with approximately equal frequencies. All three rhythm types demonstrate similar responses to standard Advanced Cardiac Life Support therapy with equal rates of out-of-hospital ROSC and hospital discharge. PQTc may be a marker of poor clinical outcome in patients with out-of-hospital VT arrest.

Prior research suggests that, in patients with empty uteri at ultrasonography, endometrial stripe thickness may be predictive of ectopic pregnancy or the likelihood of obtaining chorionic villi after a dilatation and evacuation procedure (D+E). However, it is unclear whether the predictive value of endometrial stripe thickness is confined to patients with low beta-human chorionic gonadotropin (beta-hCG) values. ⋯ Endometrial stripe thickness may be predictive of the risk of ectopic pregnancy and the likelihood of obtaining chorionic villi at D+E. However, its predictive value appears to be confined to patients with beta-hCG values < or =1,000 mIU/mL.

The SAEM EC Categorization Task Force was developed in response to the 1994 Macy Foundation's recommendation that emergency medicine (EM) organizations "should revise the classification of emergency departments ... to reflect the level of care available in emergency departments, and indicate whether or not facilities are adequate and whether appropriately qualified and credentialed emergency physicians are available 24 hours a day." By holding Level 1 emergency centers (ECs) to objective standards based on the quality of care delivered as well as administrative, research, and educational efforts, SAEM hopes to improve patient care. The SAEM EC Categorization Task Force is now beginning the process of reviewing ECs that provide comprehensive emergency care and serve as regional resources for education, research, and administration in EM. This standards document describes relative and critical criteria to be met in order to receive designation as a Level 1 emergency center. ⋯ Any EC is eligible for review. Any institution can initiate the review process by applying. Application materials and further information, including the policies and procedures of the SAEM EC Categorization Task Force, are available from SAEM.
