The concentration of the drug (10 mg/ml) allowed the use of small volumes for injection, alleviating some problems associated with large volume dosages. Total dosage for moose varied from 2.5 to 5 mg carfentanil (0.006 to 0.014 mg/Kg). Mean induction time for moose receiving at least 3 mg was 5.0 minutes (SD = 2.1, n = 75). Dioprenorphine (M50-50) was used as the antagonist. During 1983, generally 14 mg were given IV and 6 mg IM. In 1984, dosage was increased and generally 20 mg were given IV and 10 to 20 IM, and 3 moose were given 30 mg IM only. Mean recovery time was 4.2 minutes (SD = 1.9, n = 52), excluding the IM-only dosed moose. Hyperthermia, acute capture myopathy and/or narcotic recycling were attributed to 6 mortalities (6.5%) directly associated with immobilization. Causes of mortality and ways to minimize it are discussed.</p> ER -
