Abstract: | Propofol was administered to 49 cats to induce anaesthesia. The mean dose required was 6.8 mg/kg and this was not affected by prior administration of acepromazine maleate. In 27 cases, propofol was also used as the principal maintenance agent (mean dose rate 0.51 mg/kg/minute). Inductions were very smooth and problem free. Intubation was easily achieved in 15 cats with the aid of local desensitisation by lignocaine spray or neuromuscular relaxation by suxamethonium. Heart rate did not vary significantly during induction or maintenance of anaesthesia but respiratory rates did fall significantly. Recovery from anaesthesia was remarkably smooth in all cases and there was no significant difference in recovery times between the cats in which halothane was the principal maintenance agent and cats which received propofol alone. Side effects were seen during recovery in eight cats and included retching, sneezing and pawing of the face. |
