Blood concentrations of remifentanil during and after infusion in horses anesthetized with isoflurane and dexmedetomidine.

Objective: To determine blood remifentanil concentration in isoflurane-anesthetized horses during and after a 1h remifentanil and dexmedetomidine infusion.

Study Design: Prospective study.

Animals: Six adult mixed breed horses with (mean±SD) bodyweight of 507±61kg and 14±4years of age.

Cardiopulmonary effects of an infusion of remifentanil or morphine in horses anesthetized with isoflurane and dexmedetomidine.

Objective: To examine the cardiopulmonary effects of infusions of remifentanil or morphine, and their influence on recovery of horses anesthetized with isoflurane and dexmedetomidine.

Study Design: Randomized crossover study with 7-day rest periods.

Animals: Six adult horses (507 ± 61 kg).

Stimulating thoracic epidural placement via a lumbar approach causes significant spinal cord damage in a porcine model.

Background: Continuous thoracic epidural analgesia is a valuable and common technique for analgesia but involves risk to the spinal cord. There is significant pediatric experience safely placing thoracic epidurals via a caudal approach. The use of a stimulating catheter offers the advantage of real-time confirmation of appropriate catheter placement.

Prolonged anesthesia using sevoflurane, remifentanil and dexmedetomidine in a horse.

History: A 10-year old Arabian mare had a slow-growing mass on the lower right mandible and required a large partial mandibulectomy.

Physical Examination: No abnormalities were detected apart from the mass.

Management: A temporary tracheostomy was performed pre-operatively.
