ABSTRACT Background: The aim of this study was to analyse the acid-base-balance status and blood gas values in rabbits with gastric stasis and gastric dilation syndrome. Methods: Thirty rabbits with corresponding symptoms and radiographs were sampled before, during, and after treatment and an arterial acid-base-balance status and blood gas analysis was performed. Results: pCO2, HCO3, and base excess were significantly lower in animals that were presented 12 hours after the owner had registered signs of illness than animals presented within 6 hours. Of the examined rabbits, 57% had acidosis, 83% of which were of metabolic origin. The pH returned to normal after treatment in 94% of surviving animals (24/30). Conclusions: Gastric stasis and dilation syndrome has a considerable impact on the acid-base-balance status and blood gas analysis in rabbits and its measurement is therefore valuable for assessing the patient's status and adjusting the therapy accordingly to each animal's needs. Clinical relevance: Our findings underline the importance of a swift introduction of rabbits with gastric stasis and dilation syndrome into veterinary care to prevent further impairment of secondary findings such as metabolic acidosis.
