Medical history: The dog was hit by a car 3 days ago. On the 31.05 at 13h30 Betty was hit by a car while walking without a lead. She was hit on the left side. Betty then went to the private vet. They did an X-ray and initial stabilisation. It showed a Monteggia fracture on the front left and lung contusions/blood clots. She was given Medetomidien and Methadone, as well as Synulox (AmoxiClav). During the x-ray, Betty began to bleed from the nose and was intubated. Blood was also leaking from the tube. A ‘bleeding stopper’ was administered. During sedation, a wound was treated on the front left side. There was a degloving injury over the carpus and a cut over the phalanges on the left. It was not clear whether there was a direct connection to the fracture or not. She was then referred to us. She was stabilized with O2, first methadon amd then fentanyl & Ketamin, tramexamic acid, maropitant, ondansetron and fluid boli. The day after the bandage was changed and the dog got a urinary catheter. They also did a local block because of the pain and they started sedation with Dexmedetomidin CRI. This CRI was stopped after a day, they also stopped the Ketamin CRI.
