The medetomidine was reversed with atipamezole (0.5 mg/kg). Field conditions presented challenges such as limited control over lighting, suboptimal patient positioning, and restricted power supply for endoscopy equipment. Roxadustat clinical trial The immature testicle in Western Santa Cruz tortoises was oval, reddish pink, and tightly adhered to the coelomic membrane ventral to the kidney. The surface of the gonads resembled other species with the notable exception that the ovaries lacked a significant number of primordial follicles. These gonadal characteristics were consistent, with only one individual identified as undetermined sex of the 40 samples. This field-based endoscopic gonadal evaluation was a safe and sensitive technique for determining the sex of free-living immature Western Santa Cruz Galapagos tortoises.Veterinary care of ferrets often requires chemical restraint. This study hypothesized that IM alfaxalone and butorphanol would result in clinically useful sedation without clinically relevant cardiorespiratory effects. Twelve healthy 15-mo-old ferrets of equal sexes weighing 0.75 to 1.66 kg were enrolled. Using a prospective, blinded design, ferrets randomly received either IM alfaxalone 2.5 mg/kg and butorphanol 0.2 mg/kg (low dose [LD]) or IM alfaxalone 5 mg/kg and butorphanol 0.2 mg/kg (high dose [HD]) (n = 6/group). Sedation times and induction and recovery scores were recorded by a blinded observer. Anesthetic monitor placement was attempted in all recumbent ferrets, and physiologic parameters and reflexes were recorded every 5 min until return of spontaneous movement. Data were assessed for normality using a Shapiro-Wilk normality test and analyzed by two-sample t test or Mann-Whitney U test; one ferret in HD was excluded. Ferrets in LD and HD exhibited moderate and marked sedation, with one of six and four of five ferrets tolerating monitor placement, respectively. Mean ± SD time to first effects, recumbency, and recovery in LD and HD was 2.30 ± 1.13 and 2.054 ± 1.12 (P = 0.7240), 2.87 ± 1.25 and 2.72 ± 1.41 (P = 0.8529), and 65.43 ± 32.43 and 52.30 ± 13.19 (P = 0.4212), respectively. Median (range) duration of recumbency in LD and HD was 31.12 (25.58-115.72) and 35.47 (28.27-44.42) min (P = 0.3290), respectively. Among monitored ferrets, transient mild hypotension and hypoxemia were observed. Intramuscular alfaxalone 5 mg/kg with butorphanol 0.2 mg/kg provided clinically useful sedation in ferrets with mild transient cardiorespiratory derangements.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.Alfaxalone has been successfully used intramuscularly (im) combined with medetomidine and azaperone for immobilization of small ungulates.
