OBJECTIVES To document the equine perioperative mortality rate and to highlight any factor associated with an increased risk of death up to 7 days after anaesthesia. STUDY DESIGN A prospective observational epidemiological multicentre study. METHODS Data were recorded from all equidae undergoing general anaesthesia in 62 clinics. Power calculations(More)
Patient data, physiological variables and recovery quality were extracted from 1,314 records of equine anaesthetics covering a 7-year period and analysed retrospectively. Better recovery quality was significantly associated with shorter duration of anaesthesia, longer recovery times, less invasive surgery, a lower pulse rate at induction and higher pulse(More)
Thermal thresholds were measured in eight cats after the intramuscular administration of morphine (0.2 mg/kg), buprenorphine (0.01 mg/kg) or butorphanol (0.2 mg/kg), doses commonly used in clinical practice; 0.9 per cent saline (0.3 ml) was injected as a control. Groups of six cats were used and each cat participated in at least two treatments, according to(More)
A thermal analgesiometric device was developed for unrestrained cats. Heat was provided by an electrical element potted together with a temperature sensor in thermally conductive epoxy in a 5 gm probe. This was attached to an elasticated band round the cat's thorax with an inflated bladder maintaining constant pressure between probe and skin. A safety(More)
Information on equine stress responses to anaesthesia and surgery is sparse. Six ponies were anaesthetized for 2 h with halothane and no surgery was performed. Plasma concentrations of glucose, lactate, non-esterified fatty acids, cortisol, insulin, catecholamines and adrenocorticotropic hormone (ACTH) were measured. The results were compared with those(More)
A total of 1235 tracheal aspirates taken from 724 thoroughbreds in race training, aged from two to 10 years, were examined cytologically and bacteriologically. An inflammation scoring system on a scale of 0 to 9 was devised to allow the severity of lower airway disease to be assessed from the cytological results. The inflammation scores were closely related(More)
The pharmacokinetics and thermal antinociceptive effects of buprenorphine after intravenous (i.v.) or oral transmucosal (OTM) administration were studied in six adult cats. Plasma buprenorphine concentrations were measured using radioimmunoassay in a crossover study after a dose of 20 microg/kg given by the i.v. or OTM route. Oral pH was measured. Blood for(More)
This study compared pressure and thermal thresholds after administration of three opioids in eight cats. Pressure stimulation was performed via a bracelet taped around the forearm. Three ball-bearings were advanced against the forearm by inflation of a modified blood pressure bladder. Pressure in the cuff was recorded at the end point (leg shake and head(More)
A method for measuring orbital volume using low-dose CT with contiguous 3 mm transaxial sections is described. The accuracy of the method is 1.6%, as demonstrated by comparing CT volume measurements with those derived directly from alginate impressions and on repeat scanning the precision of the measurement was judged as 1.3%. Within the same individual,(More)
The plasma concentration of buprenorphine was measured by radioimmunoassay in six female cats after the administration of 0.01 mg/kg (0.033 ml/kg) buprenorphine hydrochloride solution into the side of the cat's mouth. Blood samples were taken through a preplaced jugular catheter before and one, two, four, six, 10, 15, 30, 45 and 60 minutes, and two, four,(More)
