Respiratory paralysis
Respiratory paralysis is a life-threatening condition that can occur in dogs. In this case, there is a failure of the respiratory muscles that are responsible for inhalation and exhalation. The result is inadequate oxygen supply to the body and an increase in carbon dioxide in the blood. If not acted upon quickly, respiratory paralysis can lead to death.
Causes of respiratory paralysis in dogs
There are several possible causes of respiratory paralysis in dogs, which can be congenital or acquired. Among the most common are:
- Traumatic injuries to the head, neck or chest that damage the nerves or spinal cord that control the respiratory muscles.
- Poisoning with substances that inhibit nerve or muscle activity, such as botulinum toxin, snake venom, insecticides or drugs.
- Diseases of the nervous system, such as myasthenia gravis, Guillain-Barré syndrome, or tetanus, which cause weakness or paralysis of the respiratory muscles.
- Diseases of the muscles, such as myopathies or muscular dystrophies, that result in loss of muscle mass or function.
- Diseases of the lungs or airways, such as pneumonia, asthma, or laryngeal paralysis, that result in narrowing or obstruction of the airways.
Symptoms of respiratory paralysis in dogs
Symptoms of respiratory paralysis in dogs depend on the severity and cause of the condition. Typical signs include:
- Shortness of breath or shortness of breath
- Blue mucous membranes (cyanosis) due to lack of oxygen
- Panting or rapid breathing
- Irregular or shallow breathing
- Coughing or gagging
- Unconsciousness or coma
Diagnosing respiratory paralysis in dogs
If you suspect your dog is suffering from respiratory paralysis, you should see a veterinarian immediately. The veterinarian will perform a physical exam and pay attention to your dog's breathing and heartbeat. He will also do a blood test to measure the oxygen and carbon dioxide levels in the blood. Depending on the suspicion, he may also order other tests, such as x-rays, ultrasound or electromyography (EMG) to find the cause of the respiratory paralysis.
Treatment of respiratory paralysis in dogs
Treatment of respiratory paralysis in dogs depends on the cause and the dog's condition. The most important goal is to support breathing and increase oxygen levels in the blood. To do this, the veterinarian may take the following measures:
- Oxygen therapy: this involves giving oxygen to the dog through a mask or tube.
- Ventilation: This involves pumping air into the dog's lungs through a tube in the trachea.
- Medication: This involves giving the dog medications that stimulate or inhibit nerve or muscle activity, depending on the cause of the respiratory paralysis.
- Surgery: This involves trying to correct the cause of the respiratory paralysis, such as removing a foreign body from the airway or repairing an injury.
The prognosis for dogs with respiratory paralysis depends on the severity and reversibility of the condition. In some cases respiratory paralysis can be completely cured, in other cases it can become chronic or lead to death.
The authors assume that a veterinarian should be consulted if an animal is ill and that medication should only be taken after consultation with a doctor or pharmacist. Only an individual examination can lead to a diagnosis and treatment decision.
