Use of droperidol and fentanyl for analgesia and sedation in primates

A combination of droperidol and fentanyl produces qualitatively similar pharmacologic effects in dogs and primates. Unlike the dog, however, primates did not appear to respond to auditory stimuli. As a result of the analgesic and sedative or tranquil state produced in primates, the animals were easily handled and tolerant of painful stimuli. The principal desirable features of the combination were high analgesic and sedative potency and a rapid onset of action following intramuscular administration. High doses produced respiratory depression. However, this effect was easily reversed by administering nalorphine hydrochloride.     

Isolation of Salmonella houtenae from a cockateel

Salmonella houtenae (43:Z4,Z23:-), a biochemically aberrant serotype, was isolated from the liver and air sac of a male cockateel. This serotype is a member of Salmonella subgenus IV, which is dulcitol-negative, salicin-positive, and KCN-positive. To our knowledge, this is the first report of isolation of this serotype from an avian species.     

Intraoperative Biopsy and Microscopy During Exploratory Laparotomies

Intraoperative biopsy and microscopy were evaluated, retrospectively, in 23 exploratory laparotomies. After comparing the surgical impression to the microscopic diagnosis obtained during surgery, the use of intraoperative cytologic and frozen section examination altered the surgical plan in 13 cases and reinforced the surgical plan in 10 cases. No cases had an intraoperative microscopic diagnosis that differed from the postoperative histologic examination of paraffin sections. Recommendations for selecting cases and for using intraoperative biopsy and microscopy are included.     

Performance dependent lysine requirement of fattening pigs. 3. Effect of amino acid and energy intake on fat, protein and lysine deposition of swine

The gain in structural matter had a linear course with a corresponding feeding intensity and depending on the period of fattening. However, the animals given high-energy diets deposited 130 g protein per day during the first fattening period, this deposition being compensated in the course of further growth by a considerably lower deposition in the sense of aequifinality. Up to a live weight of 70 kg, animals subjected first to restricted feeding and then to fully balanced feeding revealed the highest protein deposition during the last period of fattening, this fact emphasizing the leanmeat character of the animal material used. The daily fat deposition was found clearly determined by energy intake and independent of amino acid supply. Lysine conversion was influenced by the intake of lysine and energy. Under feeding to norm it reached some 40 and 30% during the first and second periods of fattening, respectively.     

The EMO system in small animal anaesthesia

The EMO System was used to administer ether/air anaesthesia to dogs undergoing clinical surgical procedures. Anaesthesia with spontaneous breathing gave rise to normal oxygen tensions in arterial blood, a slight acidosis and a decrease in arterial carbon dioxide tension. When used with relaxant drugs and intermittent positive pressure ventilation of the lungs it was found that to maintain normal oxygen tensions in the arterial blood it was necessary to hyperventilate to low arterial carbon dioxide tensions. Ether/air anaesthesia with the EMO System was found to meet modern criteria for acceptability in general practice where the veterinary surgeon may be assisted in the operating theatre by a nurse or may be entirely alone.
