MENDES JUNIOR, A.F. et al. Arterial hemogasometry pre and post rhinoplasty in brachyphalic dogs with nostril stenosis. Arq. Bras. Med. Vet. Zootec. [online]. 2019, vol.71, n.1, pp.137-142. ISSN 0102-0935.

Twenty-six brachycephalic dogs with nostril stenosis, 22 males and four females, underwent bilateral rhinoplasty. Sixteen dogs were French Bulldogs; two, English Bulldogs; Six, Pugs; and two, Shih tzus, ranging in age from six months to six years. Blood samples were collected for hemogasometric analysis in the preoperative period and 30 days after surgery. For each evaluation, a 0.5ml sample of blood collected from the femoral artery was obtained in a heparinized plastic syringe. Hemogasometric evaluation was then performed on a blood gas analyzer (I-stat-Abbot®). The results of hemogasometry before and after rhinoplasty showed a reduction in the mean values of pCO2, TCO2, HCO3- and BEecf, hematocrit and hemoglobin, and an increase in pH, pO2 and SO2, indicating an improvement in the ventilatory condition of the animals after surgical correction of Nostril stenosis. Therefore, it is concluded that arterial hemogasometry is an important diagnostic tool for the diagnosis of brachycephalic respiratory syndrome and is extremely useful in monitoring the patient's response to treatment. Rhinoplasty was effective in the treatment of respiratory syndrome, promoting improvement in hemogasometric parameters that indicate respiratory acidosis secondary to airway obstruction, common in the brachycephalic races.

Keywords : respiratory syndrome; respiratory acidosis; soft palate elongation.
