What Is Your Diagnosis?

摘要

A 1-year-old sexually intact male mixed-breed dog was evaluated within an hour of being hit by an automobile. On physical examination, the rectal temperature was 38.5°C (101.2°F), the heart rate was 160 beats/min, and the respiratory rate was 60 breaths/min. Femoral pulses were weak and mucous membranes tacky. The dog was alert and responsive; both pupils were miotic, and conjunctival hemorrhage was detected in the right eye. Direct and indirect pupillary light reflexes were absent in the right eye. Several small lacerations were detected on the head, and a contusion was detected on the lateral side of the left stifle joint. The dog was nonambulatory and unable to move both hind limbs. Signs of deep pain were detected in all limbs. A catheter wasplaced in a lateral saphenous vein, and fentanyl (4.4 mug/kg [2 mug/lb], IV bolus) was administered. The dog also received standard treatment for shock. No abnormalities were detected on abdominal and thoracic radiographs. Fluids were administered IV and the dog received antimicrobials and analgesics during the night.
