Comparative StudyHemodynamic and metabolic consequences of hemodilution with different diluents.
Hemodilution was performed with the crystalloid Ringer's lactate (n = 6) and the colloid Haemaccel (n = 5) in dogs during automatically controlled total cardiopulmonary bypass with constant arterial and venous pressures. Single observations were made with Macrodex and Rheomacrodex hemodilution. Hemoglobin concentration and hematocrit were used as parameters for hemodilution. ⋯ Potassium and calcium concentrations in the blood increased significantly during hemodilution with Haemaccel. Base excess was constant during hemodilution with lactated Ringer's but decreased in all other cases. A decrease in oxygen consumption was common, and most pronounced during hemodilution with Haemaccel.
