Abstract: | Reid, J., Nolan, A.M., Welsh, E. Propofol as an induction agent in the goat: a pharmacokinetic study. J. vet. Pharmacol. Therap. 16, 488–493. The pharmacokinetics of propofol, 4 mg/kg, administered as a bolus dose intravenously (i.v.) prior to the maintenance of anaesthesia with halothane in oxygen, were determined in five goats, and a clinical impression of its use as an induction agent was made. Induction of anaesthesia was rapid and smooth, providing satisfactory conditions for intubation in all animals. Post-induction apnoea occurred in one goat and minimal regurgitation of ruminal contents was recorded in two animals. Recovery times were rapid with a mean time to standing after halothane inhalation ceased of 13.7 min. The blood propofol concentration time profile was best described by a bi-exponential decline in all five goats. The mean elimination half-life was short (15.5 min), the volume of distribution at steady state large (2,56 1/kg) and the clearance rapid (275 ml/min.kg). Propofol was shown to be a very satisfactory induction agent in the goat. |
