Abstract:
Objective —To evaluate sevoflurane as an inhalation
anesthetic for thoracotomy in horses. Animals —18 horses between 2 and 15 years old. Procedure —4 horses were used to develop surgical
techniques and were euthanatized at the end of the procedure. The remaining 14 horses were selected,
because they had an episode of bleeding from their lungs during strenuous exercise. General anesthesia
was induced with xylazine (1.0 mg/kg of body weight, IV) followed by ketamine (2.0 mg/kg, IV). Anesthesia
was maintained with sevoflurane in oxygen delivered via a circle anesthetic breathing circuit. Ventilation
was controlled to maintain PaCO 2 at approximately 45
mm Hg. Neuromuscular blocking drugs (succinylcholine or atracurium) were administered to eliminate
spontaneous breathing efforts and to facilitate surgery. Cardiovascular performance was monitored
and supported as indicated. Results —2 of the 14 horses not euthanatized died as
a result of ventricular fibrillation. Mean (± SD) duration of anesthesia was 304.9 ± 64.1 minutes for horses
that survived and 216.7 ± 85.5 minutes for horses that were euthanatized or died. Our subjective opinion
was that sevoflurane afforded good control of anesthetic depth during induction, maintenance, and
recovery. Conclusions and Clinical Relevance —Administration
of sevoflurane together with neuromuscular blocking drugs provides stable and easily controllable
anesthetic management of horses for elective thoracotomy and cardiac manipulation. ( Am J Vet Res 2000;61:1430–1437)
