Diabetic Ketoacidosis (DKA) - Symptoms, diagnosis, clinical presentation, assessment

DKA symptoms and diabetic ketoacidosis in dogs -

Intravenous fluid therapy should be initiated hours prior to insulin therapy and aims to correct dehydration and hypoperfusion, as well as electrolyte abnormalities. Electrolyte supplementation is frequently required in these patients, as the insulin treatment required to reduce ketone and glucose concentrations will move potassium and phosphate to a lesser extent into cells, reducing circulating levels.

Neutral insulin is administered to promote normoglycaemia and eliminate ketone bodies before the patient is transitioned to longer-acting insulin.

Two methods for neutral insulin administration are used; the intermittent intramuscular injection method and the intravenous constant rate infusion method. The intramuscular method begins with a 0. The CRI method involves the preparation of a constant rate infusion of neutral insulin.

This is administered at a dose of 0. DKA patients should be monitored closely, especially in the early stages of treatment. Vital parameters should be regularly assessed and the patient monitored closely for signs of dehydration, hypovolaemia and electrolyte abnormalities such as neck ventroflexion and muscle weakness in the hypokalaemic patient.

Due to the high fluid therapy rates often used, especially in the initial stages of stabilisation, fluid overload is a risk for these patients, and they should be monitored closely for signs such as chemosis, acute weight gain, and respiratory changes.

Patients should be weighed regularly to assess acute fluid loss or gain, and urine output should be measured and compared with fluid input regularly. This can be achieved through placement of a urinary catheter if appropriate to do so, or by weighing bedding and litter trays, or by catching urine in a kidney dish or similar when walking dogs.

Placement of a central venous catheter or peripherally inserted central catheter can be incredibly helpful in these patients and can be performed by nurses. These catheters allow regular blood draws to be performed without repeated venepuncture, as well as the administration of fluid therapy and insulin solutions.

Following successful treatment of the ketoacidosis, the patient should be transitioned onto longer-acting insulin and managed as a normal diabetic patient. DKA patients give us so much to think about as nurses, and are an ideal opportunity for us to use more practical skills, such as placing sampling lines, calculating and administering CRIs, and interpreting blood gas results.

We see diabetic ketoacidosis DKA. Pathophysiology Diabetes mellitus results either from an insulin deficiency, or insulin resistance the impaired action of insulin.

When this process cannot occur effectively, two main things result: Glucose remains in the bloodstream as the body cannot utilise it in cells, or effectively convert it to glycogen for storage, resulting in hyperglycaemia The body breaks down lipids in the body to provide an alternative energy source The metabolism of lipids to provide energy causes free fatty acids to be released into the bloodstream, where they are converted to ketone bodies and triglycerides by the liver.

There are three major ketones: Acetone Aceto-acetate Beta-hydroxybutyrate These can be used as an energy source in short-term situations where there is a lack of usable glucose or a reduced nutritional intake.

DKA Diabetic ketoacidosis occurs when the process of ketone formation and metabolism becomes unregulated. Clinical Signs The most common clinical signs of DKA include: Depression Anorexia Vomiting The severity of these clinical signs can vary from mild dehydration, polyuria and polydipsia, through to collapse with severe dehydration and hypovolaemia.

Diagnostics DKA is characterised by the presence of hyperglycaemia, ketonaemia or ketonuria, glucosuria and metabolic acidosis. These include: Full Biochemistry and Haematology To detect any contributing diseases, confirm the presence of hyperglycaemia, evaluate the degree of electrolyte disturbance present, detect any inflammation or infection present.

Pancreatic Lipase To determine whether pancreatitis is present. Urine Analysis Including dipstick, specific gravity, sediment examination and culture as UTIs are common in diabetic patients. Venous Blood Gas Analysis To confirm whether metabolic acidosis is present.

Thoracic and Abdominal Imaging Such as abdominal ultrasound or thoracic radiographs to detect any concurrent or contributing diseases. There are some differences in the historical and exam findings, risk factors and blood results between dogs and cats.

Below are some tips on cats followed by dogs. Historical findings: Polyuria, polydipsia, weight loss, anorexia, vomiting and lethargy. Physical exam findings: Thin body condition, dehydration, icterus and hepatomegaly. Risk factors: Mean age 9 years range 2 years to 16 years.

No breed or sex predilections. Most DKA cats are newly diagnosed diabetics. CBC findings: Anemia, neutrophilia with left shift and Heinz bodies thought to be correlated to Beta-hydroxybutyrate concentrations.

Biochemical findings: Hyperglycemia, ketonemia, acidemia, elevated ALT, hypercholesterolemia, azotemia, hyponatremia pseudo , normokalemia or hyperkalemia, normophosphatemia or hyperphosphatemia and hypomagnesemia.

Potassium and phosphorus levels will drop with fluid therapy. Azotemia more common in cats than dogs. Physical exam findings: Overweight or underweight, dehydration, cranial abdominal organomegaly, heart murmur, mental dullness, abdominal pain, dyspnea, coughing, abnormal lung sounds and cataracts.

Risk factors: Median age 8 years range 8 months to 16 years. Neutrophilia with left shift and thrombocytosis also common. Biochemical findings: Hyperglycemia, ketonemia, acidemia, elevated ALP almost all dogs with DKA.

Elevated ALT, AST and hypercholesterolemia in approximately half of dogs. Hyponatremia pseudo , normokalemia or hyperkalemia, normophosphatemia or hyperphosphatemia and hypomagnesemia. Ketones develop in the blood before the urine so you can use plasma to diagnose for ketones earlier.

This can be done on the urine dipsticks that look for ketones so there is no need for additional equipment. Goal of treatment of DKA in dogs and cats is rehydration, drop glucose, normalizing pH, eliminate ketones, manage electrolyte imbalances and address concurrent diseases or underlying disease.

Treatment includes aggressive fluid therapy most important , potassium and phosphorus supplementation, insulin therapy and possible bicarbonate administration rarely needed. Insulin therapy is also a mainstay of DKA therapy.

Two main protocols include regular insulin constant rate infusion CRI or regular insulin intermittent intramuscular IM. The blood glucose BG is measured every 2 hours with CRI.

BG is measured every hour with IM. Bicarbonate therapy is described but is only reserved for severely acidemic patients generally, pH less than 7 after 1 hour of fluid therapy per American Diabetes Association. This is not commonly performed. Risks in humans include cerebral edema, increased ketogenesis, worsening hypokalemia, and paradoxical cerebral acidosis.

Internal Medicine, Critical Care. Diabetic Ketoacidosis in Dogs: Diagnosis and Treatment of DKA. What is DKA in Dogs and Cats? Normal Glycolysis, TCA Cycle, and Electron Transport Chain In a normal animal, glucose enters the cell with help of insulin — undergoes glycolysis to pyruvate within cytosol — pyruvate moves into mitochondria energy generating organelle in the cell to enter the TCA cycle and ATP is formed.

Ketone Formation in Dogs and Cats When glucose cannot enter the cell, free fatty acids are broken down lipolysis and move into the cell to undergo beta-oxidation creation of pyruvate.

Summary of Diabetic Ketoacidosis DKA in Dogs and Cats When there is no insulin the body cannot utilize glucose and there is no intracellular glucose.

The body then uses ketone bodes as an alternate source. When there is decreased insulin and increased counterregulatory hormones fatty acids are converted to AcCoA and then ketones. In the non-diabetic, AcCoA and pyruvate can enter the CAC and ETC to form ATP.

Now to the clinically important stuff… Diagnosis of Diabetic Ketoacidosis DKA in Dogs and Cats There are some differences in the historical and exam findings, risk factors and blood results between dogs and cats.

Cats Historical findings: Polyuria, polydipsia, weight loss, anorexia, vomiting and lethargy.

Diabetic Ketoacidosis DKA symptooms a serious Eating disorder treatment facilities life-threatening complication of diabetes mellitus that can occur in DKA symptoms and diabetic ketoacidosis in dogs and cats. Ketone bodies are DAK by lipolysis breakdown of fat of ketpacidosis and beta-oxidation when the metabolic demands of the cells are not met by the limited intracellular glucose concentrations. This provides alternative energy sources for cells, which are most important for the brain. The three ketones that are formed include beta-hydroxybutyrate, acetoacetate, and acetone. Beta-hydroxybutyrate BHB and acetoacetate are anions of moderately strong acids contributing most to the acidemia low blood pH.

Diabetic ketoacidosis, a complication of diabetes ektoacidosis, is keroacidosis important differential for sympoms collapse symptmos dogs and cats.

However, it requires bicarbonate which may not be routinely measured. Figure 7 shows how to calculate the anion gap. The anion gap can also be increased in other disease processes.

However, a normal or only mildly increased lactate and creatinine and low risk of toxin exposure makes a diagnosis of diabetic ketosis much more likely. Figure 7: Calculation of the anion gap and representation of a high anion gap.

Extended minimum database Given the high prevalence of concurrent disease, an extended minimum database for all patients should ideally include complete blood count, serum biochemistry with electrolytes ideally with pancreatic lipase serologyurinalysis and culture and thoracic and abdominal imaging.

Additional points Dogs with suspected DKA should not undergo testing for hyperadrenocorticism at the time of emergency presentation, as this is highly likely to result in a false positive result due to being systemically unwell. Cats, in particular, are at risk of hepatic lipidosis and can often be affected by cholangiohepatitis.

If liver enzymes are elevated then ultrasonographic evaluation and possibly aspiration of the liver and biliary system may be indicated. Urinalysis Urine-specific gravity is usually low secondary to osmotic diuresis but concurrent renal disease is also possible, particularly in cats.

Cytology: Diabetic patients often have problems mobilising white blood cells to sites of infection and therefore, may have an inactive urine sediment, even with infections. A urine culture is therefore always recommended. Empirical antimicrobials may be started where there is a concern for a urinary tract infection.

Outline treatment plan Every patient presenting for DKA will be subtly different and require a tailored treatment plan. Those with severe acidaemia, electrolyte abnormalities, known comorbidities or previously poorly controlled diabetes, should be considered for transfer to a specialist centre once initial assessment and stabilisation has been performed.

However, the guidelines below address the key points that should be considered for the initial stabilisation and ongoing management of DKA patients.

Fluid resuscitation If physical examination is compatible with shock, an element of hypovolaemia is likely. Administration of judicious fluid boluses eg.

Cats are more at risk of volume overload compared to dogs and greater care should be taken with repeated fluid boluses.

A note on sodium, glucose and osmolality Sodium levels can quickly change in response to fluid therapy and insulin. demyelineation or cerebral oedema. Patients with DKA have a variety of reasons to have abnormal sodium concentrations which can impact on fluid therapy decision making:.

Treatment of other electrolyte abnormalities and metabolic acidosis Potassium Almost all patients will be total-body potassium depleted but this can be masked by dehydration and acidosis. This is because insulin therapy will worsen hypokalaemia by shifting potassium intracellularly and there will likely be ongoing renal losses osmotic diuresis and coexistent hypomagnesaemia and gastrointestinal losses vomiting and diarrhoea or malabsorption syndromes.

Phosphorous Phosphorous is no longer empirically supplemented in people with DKA but cats in particularly are at risk of haemolytic anaemia secondary to hypophosphataemia. In cats this can occur if phosphorous levels decrease or if the concentration drops rapidly dogs are slightly more resistant.

Ideally phosphorous levels should be measured and supplemented as required. However, if monitoring is not available, and particularly if there is any indication of a haemolytic anaemia on daily monitoring, a constant rate infusion can be started.

Magnesium Measurement of ionised magnesium levels is not readily available. However, if there is a concern for hypomagnesaemia particularly a hypokalaemia not responding to aggressive potassium supplementationthen empirical treatment eg.

Bicarbonate therapy Bicarbonate therapy is rarely necessary as the acidosis usually improves rapidly with fluid therapy alone.

However, this is based on little evidence. Risks include cerebral oedema, exacerbation of hypokalemia, increased ketogenesis and paradoxical cerebral acidosis increased carbon dioxide production in animals that are not adequately ventilating. Maintenance fluid plan It is not uncommon to have DKA patients to require very high fluid rates.

This should be carefully calculated and regularly reassessed to ensure that excess losses are being replaced but also that there is no risk of volume overload.

Weighing patients every four to six hours can help to monitor for changes in hydration. Insulin therapy There are now many suggested protocols for the type, route and dose of insulin to be administered to patients with DKA. These can easily be found in textbooks or associated articles see reference list.

However, there is no conclusive evidence that any particular protocol is superior, and the most important thing is that patients are receiving some insulin in order to reverse the ketosis. The main considerations are:.

Nutrition Although it is rarely possible to institute feeding immediately, anorexia of more than three days in dogs and any duration in cats should prompt consideration for assisted enteral feeding. Parenteral feeding may also be required depending on other comorbidities.

Easily placed feeding tube options in dogs and cats include naso-oesophageal or nasogastric tube and oesophagostomy tube. Nasal tubes are more likely to be used initially as they do not require general aesthesia to place.

Diet options suitable for this small tube size include Royal Canin convalescence powder or the convenient Royal Canin low fat liquid for dogs. Ideally patients can then be transferred onto a veterinary prescription diet for diabetes.

This is particularly important in cats where it can help to aid diabetic remission. Antimicrobials Diabetic patients do not have normal immune systems. Although urine and any other appropriate samples based on minimum database assessment should ideally be taken first, empirical antimicrobial therapy can be considered in the presence of:.

Monitoring in hospital Ongoing monitoring of blood glucose, particularly whilst on insulin infusions, is important to detect hypoglycaemia. Electrolyte are also likely to change, and assessment every four to six hours may be required initially. The impact of recurrent sampling and the development of anaemia, particularly in cats, should be carefully considered.

A jugular catheter is incredibly useful for blood sampling, as well as providing multiple ports for several different infusions for example, compound sodium lactate fluid cannot be administered with phosphate.

However, if this cannot be placed, then marginal ear vein sampling using a 25G needle can be performed. The medial saphenous vein in cats is also a good site for intravenous catheter placement if both cephalic veins have been used.

Subcutaneous glucose monitoring systems are also available and are clinically accurate in patients with DKA — although accuracy is better in well hydrated patients Reineke et al, However, the median hospitalization times can be six and five days respectively.

Management of DKA can therefore be costly and owners should be appropriately informed of this prior to starting treatment. Post-hospital management As with any recently diagnosed diabetic, do not try to determine the ideal insulin dose in hospital.

Start at the low end of the dose range and then discuss options with the owner for at home or in hospital assessment of control.

Options at this time include:. What percentage of cats with DKA are reported to have a concurrent disease? Which is the predominant ketone in patients with DKA?

Beta-hydroxybutyrate B. Acetoacetone C. What is the maximum rate at which sodium concentrations should change after starting treatment for DKA? What percentage of cats have been reported to have repeated episodes of DKA?

Pathophysiology

If left untreated, diabetic ketoacidosis can lead to neurological problems due to swelling of the brain, kidney failure, pancreatitis, anemia, and even death. The symptoms for diabetic ketoacidosis are similar to diabetes mellitus, but more severe. They include:. Insatiable thirst.

Large increase or decrease in appetite. Frequent urination and lack of urinary control. Severe weight gain or weight loss.

Lethargy and lack of responsiveness. Ketoacidosis occurs after a dog has developed diabetes mellitus and becomes subsequently dependent upon insulin to break down glucose in their blood. The extreme condition arises most frequently after periods of high stress, surgery, or serious infections affecting either the urinary tract, respiratroy system, or skin.

The goal of treatment is to reduce thirst, urination and appetite by keeping the blood sugar within a certain range. Insulin is the cornerstone for diabetes treatment, and it is given by an injection under the skin twice a day at mealtimes — which should be the same amount of food given at consistent times.

Diets that have higher fiber content may help in maintaining healthy blood sugar levels, but many dogs do well on any complete and balanced diet that they enjoy eating. Diabetes treatment may also involve managing other conditions that can decrease the effectiveness of insulin and make regulating blood sugar more difficult.

After starting insulin, a monitoring test called a blood glucose curve is performed to check the sugar level range throughout the day. This test allows your veterinarian to determine if the insulin dose needs adjusting.

Insulin may need adjusting more often in the early stages of treatment before finding an appropriate dose, and it should never be increased without your veterinarian's instructions.

Because it is possible for insulin to cause low blood sugar hypoglycemia , your dog should always be monitored for signs of weakness, poor appetite, confusion, tremors or even seizures. If you think your dog might be experiencing these signs, Karo syrup should be applied to their gums.

Then contact your veterinarian immediately for further directions. Insulin therapy There are now many suggested protocols for the type, route and dose of insulin to be administered to patients with DKA.

Abnormal mentation on presentation has been associated with a poor outcome in DKA patients. Cardiovascular assessment Assessment of extravascular dehydration and intravascular hypovolaemia volume depletion: Extravascular — including skin tent, tacky mucous membranes, sunken eyes; Intravascular — including altered mentation, pulse quality, heart rate; and Also note evidence of concurrent heart disease eg.

abnormal rhythm or murmur which may affect fluid administration. Plasma can also be used on urine test strips see below. Considerations for initial stabilisation Fluid resuscitation Correction of electrolyte and acid base abnormalities Fluid resuscitation If physical examination is compatible with shock, an element of hypovolaemia is likely.

Patients with DKA have a variety of reasons to have abnormal sodium concentrations which can impact on fluid therapy decision making: Hyperglycaemia can result in increasesed water retention in the intravascular space and therefore a pseudohyponatraemia via dilution.

Fluid therapy alone can rapidly decrease blood-glucose concentrations and this has led to the common recommendation to only start insulin therapy after fluid resuscitation to avoid rapid changes in sodium. However, one study in dogs failed to show an increase in complications when starting insulin within six hours of presentation.

Ketosis will only resolve with Insulin therapy and delaying treatment further is unlikely to be beneficial. Patients may also be hypernatraemia due to concurrent cardiac or renal disease which prevents adequate sodium excretion. Patients may also experience dramatic solute free water loss through the urinary or respiratory tracts.

Sodium chloride NaCl 0. However, it is also acidfying and recent research in people has suggested that the use of buffered crystalloids with lower sodium concentrations eg. compound sodium lactate are not associated with a greater risk of cerebral oedema. Rarely, some patients will require a personalised intravenous fluid therapy bag, made up to contain a set sodium concentration to avoid rapid changes in osmolality.

Seek specialist advice for patients with marked, or persistent sodium derangements or those who have already experienced rapid changes. Considerations for ongoing therapy include: Maintenance fluid therapy plan; Insulin therapy; Nutrition; Antimicrobials; and Monitoring.

The main considerations are: Short-acting insulins are the generally the preference for management of DKA as they can be titrated to effect.
