Hypotension and pruritus induced by neuraxial anaesthesia in a cat

Although preventive epidural morphine administration with bupivacaine is effective in producing long-lasting analgesia, neuraxial anaesthesia can cause cardiovascular depression and pruritus. This report presents the development and treatment of hypotension and pruritus after intrathecal morphine and bupivacaine administration in a 3-year-old female spayed Domestic Short-hair cat presented for surgical repair of a torn right cranial cruciate ligament. Opioid-induced pruritus is not usually considered a frequently occurring complication, but may be easily misinterpreted as being dysphoria in recovery. It can be treated by administration of ondansetron, with human patients usually responding within 30?min after treatment.
