Background : Information regarding the anaesthetic management for pulmonic balloon valvuloplasty (PBV) in dogs is scarce. We present data from dogs receiving dexmedetomidine combined with inhalational anaesthesia during PBV. Methods : Anaesthetic records from dogs receiving dexmedetomidine (n = 11) and a control group (n = 29) anaesthetised for PBV between 2012 and 2020 were analysed. Intraoperative variables potentially affected by dexmedetomidine administration were compared between groups. Results : Demographic characteristic and anaesthetic agents administered were similar between groups. The incidence of hypotension (mean arterial pressure (MAP) < 60 mm Hg) was 25% for dexmedetomidine and 29% for control (p = 0.8); however, dexmedetomidine group received vasopressors for a shorter time (p = 0.02). The incidence of bradycardia was 100% and 96% for dexmedetomidine and control (p = 0.5), but antimuscarinic agents were administered more frequently to the latter (p = 0.014). Conclusion : Dexmedetomidine may be a useful adjuvant to general anaesthesia during PBV in dogs and reduced the use of vasopressors and antimuscarinics.
