Definition of Emphysema
Emphysema is the pathological accumulation of air within an organ or tissue. In almost all cases, emphysema refers to the abnormal build-up of air in some part of the respiratory tract. It is thought that when a dog has emphysema, air is able to enter the lungs fairly normally on inspiration, but for some reason cannot leave freely during exhalation, causing the air to become trapped in places where it doesn’t belong.
Emphysema in domestic dogs is commonly caused by a skin or internal wound, which allows air to be brought into tissues through the movements of muscles surrounding the laceration. Trauma, either blunt or penetrating, to the lungs, trachea (windpipe), esophagus or chest (thoracic) wall, can cause ulcerations or lacerations that lead to emphysema. Inflammatory lung illnesses, such as chronic obstructive pulmonary disease (COPD) and chronic sterile bronchitis, can contribute to emphysema, as can cancer (neoplasia)
Dogs with emphysema may show no observable signs of illness. When visible symptoms do occur, they may come on suddenly, slowly or intermittently. The exact mechanisms leading to the abnormal accumulation of air in respiratory tissues are not well understood. However, it is suspected that inflammation, physical pressure and other as yet unknown forces cause disruption and breakdown of essential lung tissues, which in turn causes inhaled air to be diverted to and accumulate in
If a dog with emphysema shows clinical signs of the disease, it almost always will involve some form of respiratory distress.When presented with a dog in respiratory distress, the veterinarian will take a history and perform a physical examination. He probably will rather quickly recommend taking thoracic radiographs (chest X-rays), which may or may not identify the cause of the dog’s condition. Routine blood work (a complete blood count and serum biochemistry profile) and urinalysis
The goals of treating emphysema in companion canines are to relieve the dog’s immediate distress and improve and manage its overall respiratory function.If a dog is in severe respiratory distress as a result of emphysema, it may need to be hospitalized and either placed in an oxygen cage or provided concentrated oxygen with a mask or through a nasal oxygen catheter. Thoracostomy tubes can be surgically placed into the animal’s chest to provide continuous suction
