OBJECTIVES To investigate whether intravenous injection of Infoson facilitates the assessment of left ventricular wall motion and definition of endocardial border and thereby reduces inter- and intra-observer variability during dobutamine stress echocardiography. BACKGROUND Clear detection of the endocardial border is essential during dobutamine stress(More)
Albunex is a new ultrasound contrast agent consisting of air-filled microspheres of heat-aggregated human albumin suspended in a 5% (w/v) solution of human albumin for infusion. The structural alterations induced in the albumin molecules during heat aggregation may cause the formation of new epitopes that may provoke an immunological response in recipients.(More)
OBJECTIVES This study was designed to investigate in patients the effect of a new transpulmonary echo contrast agent, made from 5% human serum albumin (Albunex), on systemic and pulmonary hemodynamics and the influence of the contrast doses on left ventricular opacification. BACKGROUND New intravenous transpulmonary echo contrast agents are promising,(More)
INTRODUCTION The aim of this study was to assess the effect of Albunex, a vascular contrast agent based on albumin-coated air microbubbles, on pulsed Doppler and colour-coded duplex sonography of the cranial vasculature. METHODS Twenty healthy male volunteers received intravenous injections of contrast in single doses ranging from 0.08 to 0.30 ml/kg.(More)
BACKGROUND Before 2003, the sale of paracetamol in Norway was restricted to pharmacies only. In November 2003 this place of sale restriction was lifted, allowing sale of paracetamol in non-pharmacy locations. The purpose of this study was to investigate the incidence, severity and mortality of paracetamol poisoning before and after the lifting of the place(More)
BACKGROUND AND HYPOTHESIS Multiple contrast-enhanced echocardiographic studies are to be expected in patients with cardiac ischemic disease, but the sonication process used to produce the echocontrast agent Albunex may result in new epitopes that could cause an immunogenic response. METHODS Repeated exposures to intravenous Albunex over a period of time(More)
BACKGROUND Contrast echocardiography is a useful tool for assessing repeatedly patients with coronary artery disease. Nevertheless, elevated pulmonary artery and systemic blood pressures likely to be associated with cardiac ischemia may limit the left ventricular opacification (LVO) because of the microspheres' sensitivity to pressure. OBJECTIVE To(More)
