History

A 5-year-old castrated male Beagle was referred for evaluation following 3 episodes of signs of neck pain occurring during a 6-week period. Prior to evaluation, the dog was treated with prednisone administration and exercise restriction, which were successful in alleviating the clinical signs after the first and second episode. However, at the time of the third episode, signs of neck pain persisted despite treatment. Consequently, the dog was referred.

No abnormalities were found on physical and neurologic examinations, with the exception of a lowered head carriage and severe signs of pain with manipulation of the neck in any direction.

History

An approximately 2-month-old 16.1-kg (35.4-lb) castrated male Hampshire lamb developed signs of pelvic limb ataxia at 30 days after birth, which had subsequently progressed to paraplegia. The time course of the progression was not provided by the owner. The lamb was euthanized by means of an IV barbiturate overdose injection. The lamb underwent necropsy within 24 hours after euthanasia at the Michigan State University Veterinary Diagnostic Laboratory. The lamb was born on a farm that raised lambs specifically for show purposes (so-called club lambs) and was the second lamb of the herd to develop paraplegia.

Abstract

Objective—To determine the relationship between different body positions during recumbency on the cranial migration of epidurally injected methylene blue in canine cadavers.

Sample Population—21 fresh cadavers of clinically normal adult female mixed-breed dogs.

Procedure—Dogs were randomly assigned to the following 3 groups: dogs remaining in right lateral recumbency (n = 7), dogs rotated from left to right lateral recumbency (7), and dogs rotated from dorsal to right lateral recumbency (7). Each dog received an epidural injection of 0.05% methylene blue (0.1 mL/kg) at the lumbosacral space. A dorsal laminectomy of the vertebral column was made, and cranial extent of methylene blue in 4 quadrants (right lateral, left lateral, ventral, and dorsal) was determined by examining dura mater staining.

Results—No significant difference was found among groups in regard to body weight or body condition score. Epidural cranial migration of methylene blue in the right lateral quadrant was significantly greater in dogs that remained in right lateral recumbency than in dogs that were rotated from left to right lateral recumbency. No significant difference was found within groups for epidural cranial migration of methylene blue between each quadrant. No significant relationship was found between body weight or body condition score and epidural cranial migration of methylene blue.

Conclusions and Clinical Relevance—Body positioning and amount of recumbency time influence cranial migration of epidurally injected methylene blue. If greater cranial migration of an epidurally administered drug is desired, placing the patient in lateral recumbency with the surgical site on the dependent side may precede surgery.

An 11-year-old 32-kg (70.4-lb) spayed female Labrador Retriever was evaluated at the University of Georgia College of Veterinary Medicine because of exophthalmos and epiphora of the right eye. Additionally, the owners perceived that the right eye was painful because the dog would squint that eye when the area of the head near the eye was touched. Physical examination findings were considered normal with the exception of exophthalmos, decreased retropulsion, and slight protrusion of the third eyelid of the right eye. Signs of pain were elicited when transpalpebral pressure was applied to the right eye. Examination of the left eye revealed

An 11-year-old (44.5-kg [97.9-lb]) sexually intact male Weimaraner was evaluated at the Veterinary Teaching Hospital of the University of Georgia because of a 2-day history of weakness and difficulty rising from a lying position associated with all 4 limbs. Several years earlier, the dog had bilateral cranial cruciate ligament disease and tibial plateau leveling osteotomies were performed bilaterally. Three months prior to evaluation at the hospital, the right tibial plateau leveling osteotomy plate was removed because of lameness and suspected infection. Electrocardiographic abnormalities were not detected during any of the dog's previous anesthetic episodes. The dog had no other pertinent

A 6-year-old 24.1-kg (53.0-lb) neutered male Treeing Walker Coonhound was presented because of a 3-day history of progressive dull mentation and gait change. Two days earlier, the dog acutely appeared dull and developed a hypermetric gait in the thoracic limbs. The dog was treated with carprofen (unknown dosage) by the primary veterinarian. The following day, the dog developed tremors and was treated with methocarbamol (1.74 mg/kg [0.79 mg/lb], PO, q 12 h). On the third day, the dog began stumbling and falling to the left side. Because of progressive worsening of the dog's condition, a referral evaluation was scheduled. At

History

A 7-year-old 8.1-kg (17.8-lb) spayed female Cocker Spaniel–Poodle mix was evaluated because of lethargy, behavioral changes, and signs of pain that were difficult to localize. Four months prior, the dog started to have signs of pain and displayed aggressive behavior. One month later, the dog fell and subsequently developed intermittent ataxia of the pelvic limbs and a reluctance to bear weight on the right pelvic limb. The dog was treated for suspected intervertebral disk herniation, but its condition did not improve, and a referral examination was arranged. Additional history included enucleation of the right eye owing to a ruptured

A 9-year-old 42-kg (92.4-lb) neutered male Golden Retriever was referred to the University of Georgia because of chronic, progressive ambulatory paraparesis of 3 weeks’ duration. At the onset, the dog appeared to be in pain and had difficulty standing up on the pelvic limbs. The referring veterinarian treated the dog with meloxicam (0.8 mg/kg [0.36 mg/lb], PO, q 12 h). One week later, the dog began scuffing the dorsum of the foot of the right pelvic limb. Administration of meloxicam was discontinued, and the dog was treated with prednisone (1.0 mg/kg [0.45 mg/lb], PO, q 12 h), with the

A 2-year-old 32.1-kg (70.6-lb) sexually intact male Bernese Mountain Dog was evaluated because of dull mentation following an episode of status epilepticus. For 1 week prior to the episode of status epilepticus, the dog had a decreased appetite. Twenty-four hours prior to the episode of status epilepticus, the dog became severely lethargic. The duration of the episode was 10 minutes. Following cessation of status epilepticus, the dog was evaluated at a local emergency practice where it was treated IV with mannitol and hypertonic saline (7.5% NaCl) solution (dosages unknown). Results of a CBC and serum biochemical analysis were considered normal
