These kitten premeds videos are meant to
demonstrate the effectiveness of medetomidine at what many of us consider
the high end premed dose; 0.015 mg/kg. By contrast, the
IM label dose of medetomidine is as high as 0.150 mg/kg for cats.
As you can see, both butorphanol and hydromorphone provided effective
sedation without excitatory consequences. Hydromorphone would be expected
to provide significantly more analgesia and for a longer duration than the
butorphanol at 1/4 the cost of butorphanol. The only caution is that cats
given hydromorphone must be monitored closely for the hyperthermia that
may occur between 2 and 6 hours postadministration.
