Recovery characteristics of dogs following anesthesia induced with tiletamine-zolazepam, alfaxalone, ketamine-diazepam, or propofol and maintained with isoflurane.

To compare characteristics of recovery from isoflurane anesthesia in healthy nonpremedicated dogs after anesthetic induction by IV administration of tiletamine-zolazepam with those observed after induction by IV administration of alfaxalone, ketamine-diazepam, or propofol. Prospective, randomized crossover study. 6 healthy adult hounds.

Effects of intravenous administration of tiletamine-zolazepam, alfaxalone, ketamine-diazepam, and propofol for induction of anesthesia on cardiorespiratory and metabolic variables in healthy dogs before and during anesthesia maintained with isoflurane.

OBJECTIVE To compare effects of tiletamine-zolazepam, alfaxalone, ketamine-diazepam, and propofol for anesthetic induction on cardiorespiratory and acid-base variables before and during isoflurane-maintained anesthesia in healthy dogs. ANIMALS 6 dogs. PROCEDURES Dogs were anesthetized with sevoflurane and instrumented.

Evaluation of intravenous administration of alfaxalone, propofol, and ketamine-diazepam for anesthesia in alpacas.

Objective: To evaluate the effects of induction of anesthesia with alfaxalone in alpacas.

Study Design: Prospective, randomized, crossover design.

Animals: Five healthy alpacas (96.

Effect of hind limb position on the craniocaudal length of the lumbosacral space in anesthetized dogs.

Objective: To investigate whether rostral extension of the hind limbs increases the cranio-caudal dorsal interlaminar distance between the seventh lumbar vertebra and the sacral bone (LS distance) in sternally recumbent anesthetized dogs.

Study Design: Prospective clinical study.

Animals: Eighteen dogs (eight neutered males, three intact males, six spayed females, one intact female) of various breeds, weighing 4-34 kg and ranging in age from 1 to 13 years.

Cerebral injury from intracarotid injection in an alpaca (Vicugna pacos).

A mixture of ketamine, xylazine, and butorphanol was inadvertently injected into the right carotid artery of a 1-year-old alpaca. Injection was followed by a brief period of recumbency and seizure activity. The alpaca recovered, but was euthanatized 72 hr later because of development of progressive neurologic deficits.

Minimum alveolar concentration of desflurane in llamas and alpacas.

Objective: To determine the minimum alveolar concentration (MAC) of desflurane in llamas and alpacas.

Design: Prospective study. Animals Six healthy adult llamas and six healthy adult alpacas.

Assessment of serum concentrations and sedative effects of fentanyl after transdermal administration at three dosages in healthy llamas.

Objective: To determine the serum concentrations and sedative effects of fentanyl after transdermal administration at 3 dosages in llamas.

Animals: 9 healthy adult female llamas (mean age, 8 +/- 3 years; mean weight, 150 +/- 18 kg).

Procedure: Llamas were allocated to 1 of 3 groups (3 llamas/group).

Minimum alveolar concentration of sevoflurane in spontaneously breathing llamas and alpacas.

Objective: To determine the minimum alveolar concentration (MAC) of sevoflurane in spontaneously breathing llamas and alpacas.

Design: Prospective study.

Animals: 6 healthy adult llamas and 6 healthy adult alpacas.

Comparison of lidocaine, xylazine, and lidocaine-xylazine for caudal epidural analgesia in cattle.

Objective: To directly compare the time to onset and duration of analgesia produced by a lidocaine/xylazine combination with that produced by lidocaine and xylazine administered alone in the caudal epidural space of dairy cattle. Design   Prospective randomized experimental study.

Animals: Nine adult (> 4 years of age) dairy cows (520-613 kg).
