  The patient above is a 3 to 4 year old DSH stray presenting in good overall health. He was a reasonably nice but nervous cat. His analgesic sedative combination included 0.1 mg/kg hydromorphone, 0.2 mg/kg midazolam, and 0.015 mg/kg medetomidine combined and given IM in the epaxial muscle group. At 15 minutes post-injection he was quite relaxed. 1 mg/kg each of lidocaine and bupivacaine were combined to provide the regional/local anesthesia. A 25g 5/8 inch needle was used for the right block, a 27g 5/8" needle for the left block. Some local agent was focused under the scrotal incisional site. Oscillometric SAPs ran in the 120 - 130 mmHg range with MAPs in the 80s and 90s mmHg while Doppler Bps were in the low 140 mmHg range. Quiet, uneventful recovery. No reversal agents used.   The patient above is a 1 year old DLH presenting in good overall health. He was also a reasonably nice but nervous cat.
