Case Reports
Transversus abdominis plane block for exploratory laparotomy in a Canadian lynx (Lynx canadensis).
The transversus abdominis plane (TAP) block is an innovative regional anesthetic technique using local anesthetic that is gaining popularity in the analgesic management of human patients undergoing abdominal surgery. Needle placement in the TAP block is within the facial plane between the internal oblique and transversus abdominis muscles and involves the abdominal and thoracic nerves. ⋯ Human studies suggest that this regional anesthetic technique may provide postoperative analgesia of the abdominal wall for up to 48 hr. Because of the extent and duration of sensory blockade, this novel technique with bupivacaine was used on a Canadian lynx (Lynx canadensis), possibly providing 8-10 hr ofintra- and postoperative analgesia concurrent to exploratory laparotomy for removal of a gastric foreign body.

Case Reports
Reversible immobilization of giant otters (Pteronura brasiliensis) using medetomidine-ketamine and atipamezole.
This communication reports a partially reversible chemical immobilization protocol used for translocation and veterinary care in giant otter (Pteronura brasiliensis; GO). Six GOs (three males and three females) weighing 24.8 +/- 4.0 kg (mean +/- SD) and ranging in age from 16 to 42 mo old were anesthetized with an i.m. combination of medetomidine (29 +/- 3 microg/kg) and ketamine (3.9 +/- 0.4 mg/kg). ⋯ The mean induction time and recovery times were 12 +/- 5 and 4 min (range, 0-9 min), respectively, with an anesthesia time of 47 +/- 16 min. According to these results, the combination of medetomidine (30 microg/kg i.m.) and ketamine (4 mg/kg i.m.) is a reasonable choice for inducing anesthesia in GOs.
