ABSTRACT
Captured free-ranging North American river otters (Lontra canadensis) were immobilized for the placement of intra-abdominal radio transmitters in cooperation with the Iowa Department of Natural Resources. Twenty-four otters were induced with dexmedetomidine (0.03 mg/kg, IM), butorphanol (0.2 mg/kg, IM), and midazolam (0.15 mg/kg, IM) combined in one syringe. The otters were maintained on isoflurane during the surgical procedure. Heart rate and rhythm, respiratory rate, rectal temperature, and peripheral capillary oxygen saturation were recorded every 5 min for the duration of the procedures. The otters were reversed with atipamezole (0.3-2 mg/kg, IM), naltrexone (0.6 mg/kg, IM), and flumazenil (0.05 mg/kg, IM). Rapid and smooth induction was seen, with lateral recumbency reached within 6.2 ± 5.6 min. Episodes of resedation were seen in four otters that received 0.3 mg/kg atipamezole so the dose was increased to 1 mg/kg, and no further resedation events were noted. Two fatal complications occurred secondary to suspected respiratory arrest during recovery. This drug protocol provided a smooth and rapid induction in free-ranging river otters, but further research is required to determine the safety of this protocol for river otters in both zoo and free-ranging situations.
