Central and Peripheral Arterial and Venous-Blood in Cattle with Respect to A Acid-Base-Balance Evaluations

Veterinarni Medicina 39, 1994, 1-9

In veterinary medicine mainly venous blood is used for acid-base balance determinations. This blood, however, does not allow to evaluate the respiratory component, therefore arterial blood samples have to be taken and examined in cases requiring such measurements (respiratory tract diseases, assessment of the degree of compensation in disturbed acid-base conditions). For this reason, central and peripheral arterial blood samples from the a. axillaris and a. subclavia, and the a. auricularis, respectively, were taken from 14 head of cattle, and the values of selected acid-base parameters (pH, pCO2, pO2, HCO3, BE and SAT) were compared. Simultaneously, venous blood samples (v. jugularis) were al so examined. Comparison of arterial and venous blood samples (Tab. I) revealed statistically significant differences in pH (p < 0.01) as well as in pCO2, pO2 and SAT values (p < 0.001). In HCO3 and BE, no significant differences were observed. Comparison of arterial blood samples in relation to sampling sites (peripheral and central) disclosed no significant differences in the single parameters
