Studies were primarily related to the assessment of pain in relation to surgical procedures , and no clear distinction was made concerning the onset of acute and chronic pain .
The metrics used within the tools appeared to focus primarily on the sensory aspect of pain , with no study clearly discriminating between the sensory and affective components of pain .
Objectives The objectives were to review systematic ally the range of assessment tools used in cats to detect the behavioural expression of pain and the evidence of their quality ; and to examine behavioural metrics ( considering both the sensory and affective domains ) used to assess pain .
Use of a transdermal matrix patch of buprenorphine in cats: preliminary pharmacokinetic and pharmacodynamic data
Six domestic shorthair cats , aged three to four years and weighing 5·1 to 7·4 kg , were used to assess the thermal antinociceptive effect of a transdermal buprenorphine patch , design ed to supply 35 μg buprenorphine/hour , which was applied to the shaved thorax . The cats ' thermal thresholds were tested before the patch was applied and two , four , six , eight , 10 , 12 , 14 and 16 hours after it had been applied , and then every six hours until it was removed after 72 hours , and for a further 24 hours afterwards . Blood was collected at each time to measure the plasma concentration of buprenorphine . The patches did not produce a significant change in the thermal thresholds of the cats throughout the testing period . The mean ( sd ) peak plasma buprenorphine concentration was 10 ( 0·81 ) ng/ml
