This study assessed the influence of continuous high volume hemofiltration on right ventricular function of pigs with endotoxin induced shock. Eighteen anesthetized and ventilated pigs were studied for 240 min after the start of infusion of 0.5 mg/kg endotoxin over 30 min. Right ventricular ejection fraction (RVEF) was measured by rapid response… (More)
OBJECTIVE AND DESIGN To investigate the effects of beta(2)-adrenoceptor (beta(2)-AR) stimulation on endotoxin-induced liver damage and systemic cytokine levels in rats. SUBJECTS Standard male Wistar rats. TREATMENT A disease-model of lipopolysaccharide (LPS)-induced acute systemic inflammation was used. The beta(2)-selective AR agonist clenbuterol was… (More)
This study assesses the influence of high volume continuous hemofiltration on hemodynamics of pigs subjected to bowel ischemia/reperfusion. Twelve anesthetized and ventilated pigs were studied for 60 min during clamping of the superior mesenteric artery (SMA) and subsequently for 90 min after release of the clamp, while measuring global hemodynamics, SMA… (More)
We previously showed a beneficial effect of hemofiltration on hemodynamics of endotoxic shock pigs. To test the hypothesis that this effect of hemofiltration is caused by convective removal of factors that adversely affect hemodynamics during endotoxemia, we infused ultrafiltrate from endotoxic shock pigs into healthy pigs. Their hemodynamics were compared… (More)
Albumin is a much abused and expensive drug in intensive care units. One of the motivations for its use is the prevention of pulmonary edema by enhancing the colloid osmotic pressure (COP). Fear of pulmonary edema has led to the formation of a magic (arbitrary) albumin value varying from one intensive care unit to another. Many intensive care units start… (More)
Hemofiltration may improve the hemodynamics of septic shock and the survival of multiple organ dysfunction syndrome patients. The pros and cons of this statement are reviewed and the practical implications are discussed.
We report a patient with bronchial asthma who presented with pneumomediastinum, pneumopericardium, pneumoretroperitoneum, pneumorrhachis and extensive subcutaneous emphysema, after a period of coughing. Pathogenesis, diagnostic procedures and treatment of pneumomediastinum and its complications are discussed.
Limited information is available about the pathogenesis and pathophysiology of oedema disease (OD). Oedema disease is caused by specific enterotoxemic Escherichia coli (SLTIIv-toxin producing) strains; however, the same strains are also found in non-afflicted pigs. Furthermore, it is unclear how the 80 kDa SLTIIv-toxin can pass the intestinal barrier. In… (More)
