Retrospective case series evaluates anaesthetic protocol effects in dogs undergoing cardiac imaging, suggesting safety and feasibility.

This study assesses the effects of a specific anaesthetic protocol on dogs undergoing cardiac imaging.
Retrospective case series including 15 dogs with ASA III/IV status and various breeds.
Dogs received IV dexmedetomidine and butorphanol for premedication before general anaesthesia with propofol and isoflurane.
Heart rate and mean arterial pressure were monitored during anaesthesia, with pericardiocentesis performed preoperatively.
Heart rate ranged from 37–141 beats min−1 and mean arterial pressure from 58–117 mmHg, with mild hypotension in two cases.
No arrhythmias or mortality were observed within 48 hours post-anaesthesia.
Image quality was rated as excellent or good in most cases, indicating effective anaesthetic management.

Schiesari et al. (2026) studied this question.
