Cardiac Index during Intravenous Levarterenol Infusion in Man

Cardiac index during intravenous levarterenol infusion in man.

Cardiac indices were determined by the Stewart-Hamilton indicator-dilution method during intravenous infusions of levarterenol in 25 human subjects-The rate and duration of the infusion as well as the increase in arterial pressure and bradyeardia were varied in order to study their influences on the cardiac index. D ESPITE the great interest in levarterenol (noradrenaline), there have not been ...

Arterial-venous nitroglycerin gradient during intravenous infusion in man.

We assessed the concentration of nitroglycerin (GTN) measured in plasma at different sampling sites in the circulation during a constant i.v. infusion. Twenty patients with chronic congestive cardiac failure underwent hemodynamic monitoring during i.v. GTN infusion. Our end point was a reduction in pulmonary capillary wedge pressure by at least 25% of its control value or a 10-fold increment ov...

Accidental intravenous bolus infusion of potassium chloride in a young man with hypokalemic periodic paralysis

Hypokalemic periodic paralysis is anautosomal dominantdisease characterized by muscle weakness or paralysis with a matching fall in blood potassium levels. Paralysis attacks often occur in adolescence and are induced by strenuous exercise followed by rest, high carbohydrateor high sodiummeal content, sudden changes in temperature, and even excitement, noise, flashing lights and cold temperature...

Heparin Resistance During and Post-Intravenous Nitroglycerin Infusion

      Nitroglycerin has been reported to reduce activated partial thromboplastin time (aPTT) values in patients treated with concurrent heparin and nitroglycerin. However, studies have yielded conflicting results. To determine whether intravenous nitroglycerin alters the anticoagulant effect of heparin, we prospectively evaluated twenty patients admitted for coronary angioplasty by measurin...
