To assess the effects of simulated mouth-to-mouth (MTM) ventilation on blood gases, gas exchange, and minute ventilation during external cardiac compression (ECC) or active compression-decompression (ACD) in a swine model of witnessed cardiac arrest and bystander CPR. ⋯ In this swine model of witnessed CPR, simulated MTM ventilation was not beneficial for blood gases, gas exchange, or ventilation during ECC or ACD CPR.

To obtain current demographic data and information regarding the opinion of a stratified random sample of emergency physicians about the greatest current challenges facing emergency medicine. ⋯ Overall, the ABEM Longitudinal Study participant responses to the 1995 interim survey describe a committed group of emergency physicians who are struggling and coping with the needs of a maturing specialty and with the crosscurrents and changes in American medicine.

Flecainide toxicity can impair cardiac function and precipitate circulatory collapse, which in turn depresses clearance and redistribution of flecainide. Treatment directed at improving cardiac function is often ineffective in the presence of persistently increased flecainide levels. We report a novel approach to severe flecainide overdose using peripheral cardiopulmonary bypass support (CBS) to maintain perfusion of the liver, thereby allowing clearance of the drug. ⋯ Effective cardiac rhythm and blood pressure returned. CBS successfully supported this patient until the flecainide level decreased as a result of redistribution and normal clearance mechanisms. Unfortunately, because of severe neurologic damage sustained at the time of overdose, the patient died 4 days after admission.

To evaluate selective aortic arch perfusion (SAAP) with an oxygenated fluorocarbon emulsion, with and without aortic arch epinephrine during cardiac arrest. ⋯ SAAP with oxygenated perflubron emulsion improved ROSC, both with and without aortic arch epinephrine. The combination of SAAP with perflubron emulsion and aortic arch epinephrine resulted in higher CPP and more rapid ROSC.
