Heart rate, respiration rate, arterial blood pressure, and the electrocardiogram were monitored during anaesthesia. Analgesia was tested by electrical stimulation in the left flank. Atropine (0.03 mg/kg) was given intramuscularly before induction, but after recording of baseline heart rate and respiratory rate. The duration of analgesia was 28.7+6.9 min with TK and 82.8+26.6 min with TKX. Heart rate increased significantly within 5 min after TK or TKX administration. Respiratory rate remained unchanged after TK administration, but increased significantly from 5 to 45 min after TKX administration. Arterial blood pressure decreased significantly at 15 min with TK and 30 min with TKX. Sheep remained recumbent for 201 min with TK and 166 min with TKX. AlI recovered uneventfully. We conclude that either TK or TKX may be used for anaesthetising sheep.  aOvino-anestesia1 aWALLACE, S. S.1 aTYLER, J. W.1 aROBBINS, R. L.1 aTHURMON, J. C.1 aWOLFE, D.
