Abstract
The aim of this study was to compare effect of combinations of intravenous isotonic sodium
bicarbonate (NaHCO3), acetate Ringer, lactate Ringer and small-volume hypertonic sodium
chloride (NaCI) solutions along with oral electrolyte solutions (OES) on the treatment of neonatal
calf diarrhea with moderate dehydration and metabolic acidosis. Thirty-two calves with diarrhea
were used in the study. Calves were randomly assigned to receive acetate Ringer solution
(n=8), lactate Ringer solution (n=8), isotonic NaHCO3 (n=8) and 7.2% saline solutions (n=8),
and two liters of OES were administrated to all calves orally at the end of intravenous administration.
Blood samples for blood gas and biochemical analyses were collected at 0 hours and at 0.5,
1, 2, 4, 6 and 24 hours intervals. All the calves had mild to moderate metabolic acidosis on admission.
Increased plasma volume and sodium concentration, but decreased serum total protein
were observed within 0.5 hours following administration of hypertonic 7.2% NaCI + OES, compared
to other 3 groups. In conclusion, administration of intravenous hypertonic 7.2% NaCI solution
in small volume along with OES provided fast and effective improvement of dehydration and
acid-base abnormalities within short time in treatment of calf diarrhea with moderate dehydration
and metabolic acidosis.
