Randomized Controlled Trial Comparative StudyComparison of three intraoperative patient warming systems.
The purpose of this randomized clinical trial was to compare the efficacy of three patient warming devices (i.e., circulating water blanket, forced-air, and warming panels) used either alone or in combination on patients undergoing surgeries lasting >60 min. In total, 238 dogs were included and divided into either the celiotomy or nonceliotomy group. Dogs in each group were further divided into one of three subgroups. ⋯ Significant temperature drops occurred from time of induction (38.1°C±0.64°C) to the start of surgical procedures (36.7°C±0.95°C). Although body temperature was maintained once the warming units were started in all groups, there were significant differences in temperatures for the type of surgical procedures (i.e., celiotomies versus nonceliotomies) performed over time except for subgroup 3. The warming panels and forced-air devices were equally effective in preserving body temperature in anesthetized patients.

Remifentanil/isoflurane anesthesia in five dogs with liver disease undergoing liver biopsy.
Remifentanil is a synthetic opioid with direct action on μ opioid receptors. It has an ultrashort duration of action, and its elimination is independent of hepatic or renal function. ⋯ Intraoperative analgesia was provided by a constant rate infusion of remifentanil. Remifentanil, in combination with isoflurane, was safely and successfully used in five cases for the balanced anesthesia of dogs with hepatic diseases requiring liver biopsy via celiotomy.

Case ReportsFailure to reverse prolonged vecuronium-induced neuromuscular blockade with edrophonium in an anesthetized dog.
A case of prolonged muscle relaxation after vecuronium in an anesthetized dog is presented. After using peripheral nerve stimulation to confirm partial recovery of neuromuscular transmission, administration of 0.5 mg/kg IV of intravenous edrophonium failed to complete the reversal process. ⋯ Without monitoring neuromuscular function with a peripheral nerve stimulator until reversal was complete, it was very likely this patient would have been extubated with incomplete neuromuscular transmission. Several factors affecting the duration of neuromuscular blockade and its reversal are addressed.

ReviewA review of neuroendoscopy and potential applications in veterinary medicine.
The endoscope was first developed over 200 yr ago. Endoscopy has since been applied to many disciplines of medicine. Its application to the nervous system was initially slow and not widely accepted and mainly involved the biopsy of tumors and the treatment of hydrocephalus. ⋯ Over the past 50 yr, improvements in optical glass lenses, fiber optics, and electrical circuitry has led to better equipment and a revival of neuroendoscopy. Neuroendoscopy is now used in many diseases in human medicine including hydrocephalus, neoplasia, and intracranial cysts. This review presents the history of neuroendoscopy, the equipment and technology used, and the possible translation of techniques currently used in human medicine to veterinary medicine.

Two dogs that had ingested foreign bodies were presented with vomiting. The foreign bodies appeared as metal and dense on abdominal radiographs. Abdominal exploratory identified intestinal perforation in one case and gastrointestinal tissue trapped between the two foreign bodies adhered to each other in the second case. ⋯ Both dogs had excellent outcomes following surgical intervention. These cases demonstrate the danger of tissue entrapment between the foreign bodies as a result of the magnetic attraction between two objects. Dogs that are presented with a history of or are suspect for ingesting multiple magnets or a magnet and metal foreign bodies should be treated with surgical intervention because of the risk of gastrointestinal perforation as a result of magnetic attraction between the foreign bodies.
