Veterinary anaesthesia and analgesia
-
To determine the thermal and mechanical antinociceptive effects of two different subanesthetic constant rate infusions of racemic ketamine in cats. ⋯ Low dose rate ketamine infusions minimally affect thermal and mechanical antinociception in cats. Further studies with different nociceptive testing methods are necessary to assess whether ketamine could be a useful analgesic in cats.
-
To provide a brief introduction into Critical Incident Reporting Systems (CIRS) as used in human medicine, and to report the discussion from a recent panel meeting discussion with 23 equine anaesthetists in preparation for a new CEPEF-4 (Confidential Enquiry into Perioperative Equine Fatalities) study. ⋯ Critical incident reporting systems could be used to improve safety in equine anaesthesia - in addition to other study types such as mortality studies.

Randomized Controlled Trial Comparative Study
Comparison of postoperative effects between lidocaine infusion, meloxicam, and their combination in dogs undergoing ovariohysterectomy.
To compare the postoperative analgesic effects of intravenous (IV) lidocaine, meloxicam, and their combination in dogs undergoing ovariohysterectomy. ⋯ This study suggests that, with the scoring system used, IV lidocaine and meloxicam provide similar and adequate post-operative analgesia in healthy dogs undergoing ovariohysterectomy.
-
To evaluate the influence of different inspired oxygen fractions (FiO2) on pulmonary oxygen exchange and Tei-index of myocardial performance in propofol-anesthetized dogs. ⋯ An FiO2 of 1.0 and 0.21 impaired respiratory efficiency.
-
To assess if positive end-expiratory pressure (PEEP) titration improves gas exchange and respiratory mechanics, without hemodynamic impairment in horses during anesthesia. ⋯ Gas exchange and respiratory mechanics impairment during inhalation anesthesia can be treated using PEEP titration from 5 to 20 cmH2O, without clinically important hemodynamic effects in healthy horses.
