TREATMENT for Salt toxicity in Mini Pigs: It is very difficult to treat salt poisoning in the pig. When the brain is poisoned by sodium, the sodium enters the cerebral spinal fluid and brain tissue. If the sodium levels in the blood are lowered too rapidly, the water rushes into the spinal fluid and into the brain and causes the brain to rapidly swell. This can cause very severe brain damage (herniation of the brain, edema of the brain) which will be fatal. In the hospital, we place iv catheters and measure the serum sodium concentrations of the blood. We then give sodium rich fluids that have 10% less sodium than the measured blood concentrations – this slowly dilutes the sodium out of the system without causing brain swelling. We measure the blood sodium concentrations every 6 hours and adjust the fluids accordingly. These pigs are on iv fluids for about 3 days, until blood levels are normalized. Many of these pigs do not survive.
FIRST AID FOR THE SALT POISONED PIG: If you suspect that your pig may be suffering from salt poisoning, seek medical attention as quickly as possible. If you suspect that your pig may be suffering from salt poisoning, but cannot seek veterinary care, it is very important that you do not give plain water to your pig. If it is drinking, offer 50/50 water and Gatorade or Pedialyte rather than plain water. The Gatorade and Pedialyte contain electrolytes that will help slowly dilute the sodium levels in the blood AND sugar which will help maintain blood sugar levels in a pig that is not eating. Keep the pig indoors so that it will stay warm (or cool in the summer) and where it cannot hurt itself if it is staggering about. If you see your pig eat Play-Doh or a LARGE salty meal, and it has been less than 6 hours, and it is not showing any signs of toxicity, induce vomiting if possible. Give 2 cups of plain water, then 50/50 water and Gatorade or Pedialyte free choice and encourage frequentdrinking of this mixture. Then see your veterinarian so that blood sodium levels can be measured. Your veterinarian will want to keep your pig for approx. 12 hours to measure the sodium, and will start appropriate treatment if the sodium levels begin to rise. If your pig is already showing symptoms, do NOT induce vomiting (your pig will aspirate vomitus into the lungs because it will be impaired). Seek veterinary care immediately.
