HARTMANN, H.F. et al. Gastroesophageal reflux in dogs undergoing conventional ovariohysterectomy using different premedications. Arq. Bras. Med. Vet. Zootec. [online]. 2017, vol.69, n.5, pp.1231-1235. ISSN 1678-4162.

Gastroesophageal reflux disease arises from the gastroduodenal content flow to the esophagus and/or associated organs, which leads to the wide range of signs and clinical implications. Incidence of intraoperative gastroesophageal reflux disease in dogs is unknown. The objective was, through flexible endoscopy, to assess the presence of gastroesophageal reflux in dogs undergoing ovariohysterectomy based on analgesic drugs used in premedication (morphine, tramadol or methadone). It was concluded that there was no difference in the incidence of intraoperative gastroesophageal reflux, these drugs don't influence this behavior; however, in the morphine group some animals showed preoperative vomiting. The severity of the reflux was higher, but not significantly, in bitches undergoing the methadone according to the evaluator method used for this research.
