99mTc-Labelled serum albumin in cardiac output and blood volume studies

99m Tc-labelled serum albumin in cardiac output and blood volume studies.

The use of human serum albumin labelled with iodine-131 (RIHSA) as the radioactive indicator in the measurement of cardiac output by the external counting technique is not ideal since the emission characteristics, physical half-life, and physiological fate restrict the amount that can be administered. A more suitable material, especially because of the short physical half-life of the isotope in...

Serial Cardiac Output and Blood Volume Studies Following Cardiac Valve

DETERMINATION of the cardiac output during the early postoperative period following open heart surgery has been difficult due to technical problems in adapting the Fick and indicator-dilution methods to the bedside. The recent availability of a radioisotopedilution method using precordial detection provides a simple and reliable means of measuring blood flow in the postoperative setting. In add...

Serial cardiac output and blood volume studies following cardiac valve replacement.

Cardiac output and blood volume in severe hookworm anaemia.

The determination of cardiac output has been rendered easy and safe by the introduction of the method using radio-iodinated human serum albumin (IHSA) in conjunction with a suitable external counting system set up over the heart (Veall et al., 1954). Cardiac output is known to be increased in the presence of anaemia (Starr et al., 1934; Sharpey-Schafer, 1944; Brannon et al., 1945), but no work ...

Effect of hemodialysis on blood volume distribution and cardiac output.

Effects of hemodialysis on extracellular fluid volume distribution, left ventricular volumes, and cardiac output were determined in patients with end-stage renal disease (n = 19). Distribution of extracellular fluid loss from hemodialysis differed widely among patients, so that weight change correlated weakly with contraction of total blood volume (index of determination 29%, p less than 0.05)....
