Abstract

By means of the Astrup apparatus (Blood Microsystem BMS 2) acid-base indices in blood and cerebro-spinal fluid of clinically healthy Merino sheep at the age of one year (15 head) and of two or three years (41 head) were determined. Blood collected anaerobically from v. jugularis and liquor collected by means of the suboccipital punction in heparinized syringes and/or caplaris and liquor collected by means of the suboccipital punction in heparinized syringes and/or capillaries were examined immediately after the collection. Following indices were obtained and re-counted according to nomograms: actual pH, partial CO2 pressure--pCO2 base excess--BE, base buffer--BB, standard bicarbonate--SB, actual bicarbonate--AB, total CO2--tCO2 (Tables I, II). Indices of pH, pCO2, BE and BB indicated statistically significant differences in values when comparing liquor with venous blood (in younger ewes). As the values of the sheep cerebro-spinal fluid indices examined are not to be found in literature, the above stated values can be recommended to be used as basic values for a given age group.
