Randomized Controlled Trial
The effects of morphine on the recovery of horses from halothane anaesthesia.
To investigate the effects of peri-operative morphine on the quality and duration of recovery from halothane anaesthesia in horses. ⋯ Recoveries from anaesthesia in the morphine recipients were characterized by fewer attempts to attain sternal recumbency and standing, and a shorter time from the first recovery movement to the time of standing.

Randomized Controlled Trial
The isoflurane-sparing and clinical effects of a constant rate infusion of remifentanil in dogs.
To evaluate the isoflurane-sparing and clinical effects of two constant rate infusions of remifentanil in healthy dogs undergoing orthopaedic surgery. ⋯ Remifentanil infusions may be a useful additive to isoflurane anaesthesia in healthy dogs.

Randomized Controlled Trial
Use of ephedrine and dopamine in dogs for the management of hypotension in routine clinical cases under isoflurane anesthesia.
To determine the cardiovascular responses of ephedrine and dopamine for the management of presurgical hypotension in anesthetized dogs. ⋯ In anesthetized hypotensive dogs, ephedrine and dopamine improved cardiac output and oxygen delivery. However, the pressure-elevating effect of ephedrine is transient, while an infusion of dopamine at 10 microg kg(-1) minute(-1) improved MAP significantly by additionally maintaining TPR.

Randomized Controlled Trial
Effects of acepromazine on the cardiovascular actions of dopamine in anesthetized dogs.
To evaluate the effects of acepromazine maleate on the cardiovascular changes induced by dopamine in isoflurane-anesthetized dogs. ⋯ Previous acepromazine administration reduces the efficacy of dopamine as a vasopressor agent in isoflurane anesthetized dogs. Other beneficial effects of dopamine such as increased CO are not modified by acepromazine.

Randomized Controlled Trial
Effect of intravenous lidocaine on heart rate, systolic arterial blood pressure and cough responses to endotracheal intubation in propofol-anaesthetized dogs.
To evaluate the effect of intravenous lidocaine on coughing and variations in heart rate (HR) and systolic arterial pressure (SAP) at endotracheal intubation in propofol-anaesthetized dogs. ⋯ Intravenous lidocaine had no effect on the occurrence or intensity of coughing or on changes in SAP at endotracheal intubation in dogs anaesthetized with propofol. The use of 1 mg kg(-1) lidocaine intravenously before intubation in dogs to attenuate cough and the pressor response was not supported.
