Abstract: We describe the use of fentazin anesthesia (0.4 mg/ml fentanyl citrate, 58.3 mg/mL xylazine HCl, and 3.2 mg/mL azaperone, Parnell, New Zealand) for labyrinthine surgery in guinea pigs. Fentazin provides stable surgical anesthesia for approximately 1 hour, rapid recovery from anesthesia following the surgery, and has significant analgesic and anxiolytic properties. Its advantages in comparison to other anesthetics (for example, ketamine HCl) are discussed.
