The use of dexmedetomidine continuous rate infusion for horses undergoing transvenous electrical cardioversion–A case series.
Abstract: Five horses were presented for treatment of atrial fibrillation by transvenous electrical cardioversion (TVEC). A dexmedetomidine infusion was administered for sedation during positioning of the cardioversion catheters, and continued during general anesthesia. Shocks were applied until return to sinus rhythm. Dexmedetomidine infusion provided excellent conditions for TVEC catheter placement and procedure. Utilisation d’une perfusion continue de dexmedetomidine lors de cardioversion électrique transveineuse chez le cheval: une série de cas. Cinq chevaux présentant une fibrillation atriale ont été traités par cardioversion éléctrique transveineuse (TVEC). Pour le positionnement des cathéters de cardioversion, les chevaux ont reçu une perfusion de dexmédétomidine, poursuivie pendant l’anesthésie générale. Les chocs éléctriques sont répétés jusqu’au retour en rythme sinusal. La perfusion de dexmédétomidine a fourni d’excellentes conditions pour le positionnement des cathéters et la procédure de TVEC.(Traduit par les auteurs).

The research studies the use of dexmedetomidine in horses undergoing transvenous electrical cardioversion (TVEC). This procedure aimed to treat atrial fibrillation with dexmedetomidine providing sedation for the placement of TVEC catheters and during the general anesthesia.
Study Objective and Methodology
- The primary objective of this study was to investigate the effectiveness of dexmedetomidine infusion for sedation in horses undergoing transvenous electrical cardioversion (TVEC). TVEC is a procedure used for the treatment of atrial fibrillation, a common cardiac arrhythmia in horses.
- The research was conducted on five horses that were presented for atrial fibrillation treatment. The horses were sedated with a dexmedetomidine infusion during the positioning of the cardioversion catheters and it was continued throughout the period of general anesthesia.
- Electrical shocks were repeatedly applied until the sinus rhythm, which is the normal beating of the heart, was achieved.
Findings
- The researchers noted that the dexmedetomidine infusion provided excellent conditions for the placement of the TVEC catheters and the subsequent procedure.
- The medication effectively sedated the horses, allowing the procedure to be conducted smoothly and successfully.
- It suggests that dexmedetomidine is an effective tool in managing horses undergoing TVEC, offering significant benefits in terms of patient management and procedure success.
Conclusion
- The study concludes that dexmedetomidine infusion could be a viable and effective method of sedation in horses that are undergoing the TVEC procedure.
- It provided excellent conditions for catheter placement and the overall execution of the procedure and is, therefore, recommended for use in such instances.
- These findings could have significant implications for the veterinary field, helping to improve patient outcomes and procedure success rates in treating atrial fibrillation in horses.
