Does trazodone reduce anaesthetic agent requirement in dogs?

Area of Science:

• Veterinary Anesthesiology
• Pharmacology

Background:

• Anesthetic agent requirements in dogs can be substantial.
• Reducing anesthetic dosage is desirable for patient safety and cost-effectiveness.

Purpose of the Study:

• To evaluate the efficacy of oral trazodone in reducing injectable and inhalant anesthetic requirements in dogs.

Main Methods:

• Two randomized controlled trials were critically appraised.
• The study focused on dogs undergoing anesthesia, with trazodone administered two hours prior to induction.

Main Results:

• Trazodone demonstrated a significant minimum alveolar concentration (MAC) sparing effect for isoflurane.
• Evidence suggests trazodone has cardiovascular effects comparable to acepromazine.

Conclusions:

• Trazodone should be integrated into multimodal anesthesia protocols for dogs.
• Its use can effectively decrease the need for injectable and inhalant anesthetic agents.
