Comparison of medetomidine-ketamine and dexmedetomidine-ketamine anesthesia in golden-headed lion tamarins.

The cardiovascular, respiratory, and anesthetic effects of medetomidine-ketamine (20 microg/kg bodyweight [BW] and 10 mg/kg BW) (MK group) or dexmedetomidine-ketamine (10 microg/kg BW and 10 mg/kg BW) (DK group) were studied in golden-headed lion tamarins. Heart rate decreased after administration of both combinations; this reduction was statistically greater in the DK group than in the MK group after 15 and 45 minutes. Systolic arterial pressure decreased in a similar way in both groups, except at 15 minutes, when systolic arterial pressure was significantly lower in the DK group.

Sedative, analgesic and cardiorespiratory effects of romifidine in cats.

Objective: To evaluate the sedative, analgesic, and cardiorespiratory effects of intramascular (IM) romifidine in cats.

Study Design: Prospective, randomized experimental trial.

Animals: Ten healthy adult cats.

Evaluation of the sedative and cardiorespiratory effects of dexmedetomidine, dexmedetomidine-butorphanol, and dexmedetomidine-ketamine in cats.

Objective: To determine sedative and cardiorespiratory effects of dexmedetomidine alone and in combination with butorphanol or ketamine in cats.

Design: Randomized crossover study.

Animals: 6 healthy adult cats.

Evaluation of sedative and cardiorespiratory effects of romifidine and romifidine-butorphanol in cats.

Objective: To determine sedative and cardiorespiratory effects of romifidine alone and romifidine in combination with butorphanol and effects of preemptive atropine administration in cats sedated with romifidine-butorphanol.

Design: Randomized crossover study.

Animals: 6 healthy adult cats.
