Acute uremia is a sudden-onset condition that is characterized by high levels of urea, protein products, and amino acids in the blood. This condition usually follows sudden kidney injuries, or occurs when the urinary tubes that connect the kidney to the bladder (ureters) are obstructed. As a result, the outflow of urine is obstructed, creating an imbalance in fluid regulation and leading to a buildup of potential toxins in the body. Fortunately, acute uremia can be successfully treated and cured if it is identified on time and treated promptly.
Most dog breeds, whether male or female, are affected by acute uremia; however, exposure to chemicals such as antifreeze increases the risk of uremia. Therefore, the incidence of acute uremia is higher in the winter and fall than in other seasons. In addition, dogs are most susceptible to acute uremia between the ages of six and eight.
The condition described in this medical article can affect both dogs and cats. If you would like to learn how acute uremia affects cats, please visit this page in the PetMD health library.
As this potentially toxic blood flows through the dog's body, most systems are affected, including the urinary, digestive, nervous, respiratory, musculoskeletal, lymphatic, and immune systems.
Upon examination, dogs will appear to be in normal physical condition, with a normal hair coat, but may appear to be in a depressed state. When symptoms are apparent, signs can include loss of appetite, listlessness, vomiting, and diarrhea, which may be tinted with blood. Other symptoms may include inflammation of the tongue,ammonia-smelling breathe (due to urea), ulcers in the mouth, fever, abnormally fast or slow pulse, decreased or increased urine output, and even seizures. The kidneys may feel enlarged, tender, and firm on palpation.
Kidney failure or obstruction to urine output may be due to any of the following:
A complete blood profile will be conducted by your veterinarian, including a chemical blood profile, a complete blood count, and a urinalysis. Dogs with acute uremia may have high packed cell volume and an increased white blood cell count. The levels of certain protein enzymes and chemicals such as creatinine, phosphate, glucose, glucose, and potassium will also be high.
Urine may be collected by inserting a catheter or by fine needle aspiration into the dog; the results of which may show high levels of protein, glucose, and the presence of blood cells. In order to view and examine the urinary system clearly, contrast dyes may be injected into the bladder so that the interior of the bladder, the ureters, and the kidney are illuminated on X-ray and ultrasonography imaging.
If the uremia is due to toxic poisoning, the first step will be to eliminate the toxins from the body. This may be done through gastric lavage, where the stomach is cleansed, or by administering activated charcoal to neutralize the toxin. Specific antidotes may also be administered if the toxic agent can be identified.
Care is also aimed at re-establishing fluid balance, blood circulation, and in establishing the balance of chemicals in the blood. Strictly monitoring fluid intake, food consumption, and nutrition is very important while treatment is underway.
Some medications that may be prescribed are:
Generally, this condition has a poor prognosis for recovery. Some possible complications include seizures, coma, high blood pressure, pneumonia, bleeding in the digestive tract, cardiac arrest, fluid overload, widespread infection in the blood, and multiple organ failure.
The cost involved with the whole procedure of treatment is also very high. Sometimes, dialysis can be used until the dog is stable enough to tolerate surgery.
After the procedures are complete, it is important to monitor daily fluid levels, mineral levels, body weight, urine output, and general physical status. The entire process of recovery depends on various factors, such as the extent of organ or system damage, the origin of the disease, and the existence of other pathological conditions or diseased organs.
