- Abstract
- Cardiac output and hemodynamics were determ i n e d in the rabbit during the acute acid-base disturbance of metabolic origin by the intravenousi n fu si o n of 0.3 N hydrochloric acid or 0.6 M/L
sodium bicarbonate solution. Cardiac output was measured analyzing the saline
dilution curve recorded on physiograph the extra•
ml/min/ aterial conductivity, using Stewart-Hamilton form•
(± ula.
Under each level of plasma hydrogen ion concen
tration , arterial blood pressure, heart rate, cardiac
index, stroke volume and total peripheral resistance
were measured and relation of them were analyzed
1 . Normal cardiac index measured by saline cond
uctivity method in the rabbit was 72 C±5. 0) mJ!
min/kg. After the infusion of hydrochloric acid,
associated with the decrease of pH from 7.40 of
normal to 7.23 , cardiac index decreased to 50'
0.72 (±4.3) ml/min/kg. During metabolic acidosis,
th e higher the concentration of hydrogen ion ,
the more significantly decreased the cardiac
dex. After the infusion of sodium bicarbonate,
however, associated with the increase of pH from
7.40 to 7.51. cardiac output did not change
significantly.
