Advanced Diabetic Ketoacidosis
Diabetic ketoacidosis (DKA) is a dangerous condition characterized by a severe rise in blood sugar or hyperglycemia, depleted bodily fluids, shock, and in some cases unconsciousness. Coma and even death may occur if DKA is left untreated or if it becomes more severe due to excessive vomiting. Symptoms of DKA In the early stages of DKA, the affected individual appears flushed and breathes rapidly and deeply. This is called hyperventilation. As the condition progresses, the skin may turn pale, cool and clammy, dehydration may begin to set in and the heart rate may become rapid and breathing shallow. Nausea, vomiting and severe abdominal cramps. Blurred vision Fruity or pungent smelling breath due to the presence of acetone and ketones in the breath. Pathophysiology Although DKA can occur in patients with type 2 diabetes, it mainly develops in people with type 1 diabetes who need to take insulin for their condition. If individuals do not receive insulin, they will develop DKA. If there is a shortage of insulin, the body fails to use glucose in the blood for energy and instead fats are broken down in the liver. When these fats are broken down, acidic compounds called ketones are produced as a by-product. These ketones build up in the body and eventually cause ketoacidosis. Aside from missed or inadequate doses of insulin, another common cause of DKA is infection or illness as this can raise the level of hormones that counteract the effects of insulin. In addition, the dehydration caused by major injury or surgery can raise levels of these hormones. Diagnosis and treatment Blood tests are performed to check the sugar levels and blood pH, which is classified as acidic if it is below the usual 7.3. Unlike non-ketotic hyperosmolar coma, in DKA the blood and urine levels of keto Continue reading >>
What You Should Know About Diabetic Ketoacidosis
Diabetic ketoacidosis (DKA) is a serious condition that can occur in diabetes. DKA happens when acidic substances, called ketones, build up in your body. Ketones are formed when your body burns fat for fuel instead of sugar, or glucose. That can happen if you don’t have enough insulin in your body to help you process sugars. Learn more: Ketosis vs. ketoacidosis: What you should know » Left untreated, ketones can build up to dangerous levels. DKA can occur in people who have type 1 or type 2 diabetes, but it’s rare in people with type 2 diabetes. DKA can also develop if you are at risk for diabetes, but have not received a formal diagnosis. It can be the first sign of type 1 diabetes. DKA is a medical emergency. Call your local emergency services immediately if you think you are experiencing DKA. Symptoms of DKA can appear quickly and may include: frequent urination extreme thirst high blood sugar levels high levels of ketones in the urine nausea or vomiting abdominal pain confusion fruity-smelling breath a flushed face fatigue rapid breathing dry mouth and skin It is important to make sure you consult with your doctor if you experience any of these symptoms. If left untreated, DKA can lead to a coma or death. All people who use insulin should discuss the risk of DKA with their healthcare team, to make sure a plan is in place. If you think you are experiencing DKA, seek immediate medical help. Learn more: Blood glucose management: Checking for ketones » If you have type 1 diabetes, you should maintain a supply of home urine ketone tests. You can use these to test your ketone levels. A high ketone test result is a symptom of DKA. If you have type 1 diabetes and have a glucometer reading of over 250 milligrams per deciliter twice, you should test your urine for keton Continue reading >>
Diabetes: What Is Ketoacidosis And How Can Be Avoided & Treated?
Good question! According to Wikipedia: Diabetic ketoacidosis is a potentially life-threatening complication in patients with diabetes mellitus. In order to define ketoacidosis a little better, let's go back to the source: diabetes. Someone who is diabetic is unable to produce insulin, a hormone necessary for the transfer of sugar from the bloodstream to the cells, which in turn produce energy. If this progression is disrupted, through lack of insulin for example, the body has to try to compensate by creating energy elsewhere. And so the body starts to burn fat and muscle to meet its energy needs. Unfortunately, this chemical reaction produces molecules known as ketone bodies. In small quantities, these are fine, and it is in fact normal to have traces of them in your blood (approximately 1mg/dl). However, if the quantity of ketones surpasses this threshold by too much, it starts to affect the pH of your blood (which becomes progressively more acidic). Even the slightest drop in pH can have dangerous effects: as the quantity of the ketones in your blood increases, and the blood pH diminishes, your kidneys start having problems. Eventually, if the ketoacidosis is left untreated, your kidneys can fail and you can die from dehydration, tachycardia and hypotension. A number of other symptoms can appear in extreme cases. Fortunately for us, the quantity of ketones has to be consequential, and it usually takes a while before individuals start manifesting symptoms. In my case, my diabetes went undiagnosed for a month and a half before it was discovered, and even then my ketone levels were relatively normal. If you're a diabetic, ketoacidosis can be easily avoided by controlling your blood sugar levels and maintaining a healthy lifestyle. Some doctors, preferring to stay on the Continue reading >>
What Is The Nursing Intervention For Diabetic Ketoacidosis?
My response will be geared towards the emergent presentation amd treatment. 90+ % of the time the blood sugar will be above 500 on your glucometer. Do not let this fool You! Even if it's over 2000 (my highest treated fingerstick glucose was 2042 which wasn't even this patients personal highest) you don't need to worry about administering insulin for about 1–2 hour. You first need great IV access. Being a soon to be ICU admit, I tried my best to give them at least an 18 g and a 20 g preferably not in the AC but access is better than an inconvenient location. These patients are dehydrated so get ready to administer 2 up to 4 liters of fluid. Truthfully Lactated ringers is coming en vogue as NS can worsen the acidosis by raising the chloride levels. With labs pending (electrolytes are the important labs and either an ABG or a VBG… yes a venous gas gives equally treatable results and causes much less pain). If the potassium is above the recommended value you will be able to start an insulin drip and in case you are too in the moment to remember — giving IV insulin will tank a potassium within 30 min or less so replace potassium before administering insulin in this situation!! There are a few options for insulin replacement, some use a computerized algorithm while other base insulin dosage on patient weight ( kg x .01 units/kg/hr is one example) with hourly glucose checks. While administering insulin, if they begin having seizures you will need to give IV glucose, yes it's counter intuitive but it's necessary. Regardless, go with your facilities recommendations. Ensure quality oxygenation/ventilation because the body will do its best to correct the condition itself but sometimes the patient must be intubated. All this to say this- the goal of treatment is to: hydrate, Continue reading >>
Diabetic Ketoacidosis Treatment & Management
Approach Considerations Managing diabetic ketoacidosis (DKA) in an intensive care unit during the first 24-48 hours always is advisable. When treating patients with DKA, the following points must be considered and closely monitored: It is essential to maintain extreme vigilance for any concomitant process, such as infection, cerebrovascular accident, myocardial infarction, sepsis, or deep venous thrombosis. It is important to pay close attention to the correction of fluid and electrolyte loss during the first hour of treatment. This always should be followed by gradual correction of hyperglycemia and acidosis. Correction of fluid loss makes the clinical picture clearer and may be sufficient to correct acidosis. The presence of even mild signs of dehydration indicates that at least 3 L of fluid has already been lost. Patients usually are not discharged from the hospital unless they have been able to switch back to their daily insulin regimen without a recurrence of ketosis. When the condition is stable, pH exceeds 7.3, and bicarbonate is greater than 18 mEq/L, the patient is allowed to eat a meal preceded by a subcutaneous (SC) dose of regular insulin. Insulin infusion can be discontinued 30 minutes later. If the patient is still nauseated and cannot eat, dextrose infusion should be continued and regular or ultra–short-acting insulin should be administered SC every 4 hours, according to blood glucose level, while trying to maintain blood glucose values at 100-180 mg/dL. The 2011 JBDS guideline recommends the intravenous infusion of insulin at a weight-based fixed rate until ketosis has subsided. Should blood glucose fall below 14 mmol/L (250 mg/dL), 10% glucose should be added to allow for the continuation of fixed-rate insulin infusion. [19, 20] In established patient Continue reading >>
Metabolic acidosis occurs when the body produces too much acid. It can also occur when the kidneys are not removing enough acid from the body. There are several types of metabolic acidosis. Diabetic acidosis develops when acidic substances, known as ketone bodies, build up in the body. This most often occurs with uncontrolled type 1 diabetes. It is also called diabetic ketoacidosis and DKA. Hyperchloremic acidosis results from excessive loss of sodium bicarbonate from the body. This can occur with severe diarrhea. Lactic acidosis results from a buildup of lactic acid. It can be caused by: Alcohol Cancer Exercising intensely Liver failure Medicines, such as salicylates Other causes of metabolic acidosis include: Kidney disease (distal renal tubular acidosis and proximal renal tubular acidosis) Poisoning by aspirin, ethylene glycol (found in antifreeze), or methanol Continue reading >>
What Are Ketone Bodies And How Are They Related To Diabetes?
What are ketones? The human body normally runs on glucose that’s produced when the body breaks down carbohydrates. But when your body doesn’t have enough glucose or insulin to use the glucose, your body starts breaking down fats for energy. Ketones are byproducts of this breakdown. Those with type 1 diabetes are especially at risk for making ketones. Ketones can make your blood acidic. Acidic blood can cause a serious condition known as diabetic ketoacidosis (DKA). Because the presence of ketones is often one of the signs that a person needs medical help, those with diabetes are often encouraged to check ketones in urine or blood regularly. Ketone levels can range from negative or none at all to very high levels. While individual testing may vary, some general results for ketone levels can be: negative: less than 0.6 millimoles per liter (mmol/L) low to moderate: between 0.6 to 1.5 mmol/L high: 1.6 to 3.0 mmol/L very high: greater than 3.0 mmol/L Call your doctor if your ketones are low to moderate, and seek emergency medical attention if your ketone levels are high to very high. What are the symptoms of ketone buildup? If you have diabetes, you need to be especially aware of the symptoms that having too many ketones in your body can cause. Examples of early symptoms of ketone buildup include: a dry mouth blood sugar levels greater than 240 milligrams per deciliter strong thirst frequent urination If you don’t get treatment, the symptoms can progress. The symptoms that occur later can include: confusion extreme fatigue flushed skin a fruity breath odor nausea vomiting stomach pain trouble breathing You should always seek immediate medical attention if your ketone levels are high. What causes ketones to build up? Ketones are the body’s alternate way of fueling. T Continue reading >>
A Preventable Crisis People who have had diabetic ketoacidosis, or DKA, will tell you it’s worse than any flu they’ve ever had, describing an overwhelming feeling of lethargy, unquenchable thirst, and unrelenting vomiting. “It’s sort of like having molasses for blood,” says George. “Everything moves so slow, the mouth can feel so dry, and there is a cloud over your head. Just before diagnosis, when I was in high school, I would get out of a class and go to the bathroom to pee for about 10–12 minutes. Then I would head to the water fountain and begin drinking water for minutes at a time, usually until well after the next class had begun.” George, generally an upbeat person, said that while he has experienced varying degrees of DKA in his 40 years or so of having diabetes, “…at its worst, there is one reprieve from its ill feeling: Unfortunately, that is a coma.” But DKA can be more than a feeling of extreme discomfort, and it can result in more than a coma. “It has the potential to kill,” says Richard Hellman, MD, past president of the American Association of Clinical Endocrinologists. “DKA is a medical emergency. It’s the biggest medical emergency related to diabetes. It’s also the most likely time for a child with diabetes to die.” DKA occurs when there is not enough insulin in the body, resulting in high blood glucose; the person is dehydrated; and too many ketones are present in the bloodstream, making it acidic. The initial insulin deficit is most often caused by the onset of diabetes, by an illness or infection, or by not taking insulin when it is needed. Ketones are your brain’s “second-best fuel,” Hellman says, with glucose being number one. If you don’t have enough glucose in your cells to supply energy to your brain, yo Continue reading >>
Insulin injections are the preferred method of managing diabetes in cats. Figure 1: To administer an injection, pull the loose skin between the shoulder blades with one hand. With the other hand, insert the needle directly into the indentation made by holding up the skin, draw back on the plunger slightly, and if no blood appears in the syringe, inject gently. Tips for Treatment 1. You can do it! Treating your cat may sound difficult, but for most owners it soon becomes routine. 2. Work very closely with your veterinarian to get the best results for your cat. 3. Once your cat has been diagnosed, it's best to start insulin therapy as soon as possible. 4. Home glucose monitoring can be very helpful. 5. Tracking your cat's water intake, activity level, appetite, and weight can be beneficial. 6. A low carbohydrate diet helps diabetic cats maintain proper glucose levels. 7. With careful treatment, your cat's diabetes may well go into remission. 8. If your cat shows signs of hypoglycemia (lethargy, weakness, tremors, seizures, vomiting) apply honey, a glucose solution, or dextrose gel to the gums and immediately contact a veterinarian. Possible Complications Insulin therapy lowers blood glucose, possibly to dangerously low levels. Signs of hypoglycemia include weakness, lethargy, vomiting, lack of coordination, seizures, and coma. Hypoglycemia can be fatal if left untreated, so any diabetic cat that shows any of these signs should be offered its regular food immediately. If the cat does not eat voluntarily, it should be given oral glucose in the form of honey, corn syrup, or proprietary dextrose gels (available at most pharmacies) and brought to a veterinarian immediately. It is important, however, that owners not attempt to force fingers, food, or fluids into the mouth of a Continue reading >>
What Is Diabetes?
My current understanding compels me to formulate the following brief answer: If both type 1 (an autoimmune) and type 2 (a lifestyle) diabetes are pulled together, I’d describe them with the unifying name ‘fuel partitioning disease of insulin’. Now, that’s not to say that type 1 diabetes does not have a strong lifestyle component as well… You may rightfully ask what I mean by ‘fuel partitioning disease’? Understanding the physiological role of insulin in the body leads you to this conclusion. The general role of insulin was perfectly described by George Cahill in his Banting Memorial Lecture way back in 1971: “Insulin serves as the body's signal for the fed or fasted state. High insulin levels, the “fed” signal, initiate tissue uptake and storage of fuels. Low insulin levels, the “fasted” signal, initiate mobilization of stored fuels from tissue stores, the rate being proportional to the lowness of the insulin. Certain metabolic states such as obesity or trauma alter the concentration of insulin at which no net transfer of fuel occurs, resulting in insulin resistance or hyper-sensitivity.” Our understanding has been refined to some extent since then, but the basics are well described. In fact, where our knowledge has improved the most is the mechanisms underlying the impaired action of insulin. As it seems now, as soon as (especially superficial, below the waistline) subcutaneous fat depots fail to take up and store lipids (fat) in an appropriate (insulin sensitive) way, these lipids get deposited in less appropriate places. First, in deeper subcutaneous, then visceral, epicardial, etc. adipose depots, and if those become full as well, fat starts flooding all insulin sensitive organs, such as the liver, the pancreas, and the endothelium (the inn Continue reading >>
Diabetes With Ketone Bodies In Dogs
Studies show that female dogs (particularly non-spayed) are more prone to DKA, as are older canines. Diabetic ketoacidosis is best classified through the presence of ketones that exist in the liver, which are directly correlated to the lack of insulin being produced in the body. This is a very serious complication, requiring immediate veterinary intervention. Although a number of dogs can be affected mildly, the majority are very ill. Some dogs will not recover despite treatment, and concurrent disease has been documented in 70% of canines diagnosed with DKA. Diabetes with ketone bodies is also described in veterinary terms as diabetic ketoacidosis or DKA. It is a severe complication of diabetes mellitus. Excess ketone bodies result in acidosis and electrolyte abnormalities, which can lead to a crisis situation for your dog. If left in an untreated state, this condition can and will be fatal. Some dogs who are suffering from diabetic ketoacidosis may present as systemically well. Others will show severe illness. Symptoms may be seen as listed below: Change in appetite (either increase or decrease) Increased thirst Frequent urination Vomiting Abdominal pain Mental dullness Coughing Fatigue or weakness Weight loss Sometimes sweet smelling breath is evident Slow, deep respiration. There may also be other symptoms present that accompany diseases that can trigger DKA, such as hypothyroidism or Cushing’s disease. While some dogs may live fairly normal lives with this condition before it is diagnosed, most canines who become sick will do so within a week of the start of the illness. There are four influences that can bring on DKA: Fasting Insulin deficiency as a result of unknown and untreated diabetes, or insulin deficiency due to an underlying disease that in turn exacerba Continue reading >>
Managing Diabetes Complicated By Ketoacidosis
Go to site For Pet Owners Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus that has to be aggressively treated. Diagnosis The diagnosis is based on the presence of ketonuria with signs of systemic illness. Management guidelines Goals of treatment include the correction of fluid deficits, acid-base balance and electrolyte balance, reduction of blood glucose and ketonuria, and beginning insulin therapy and treatment of concurrent diseases. Many protocols for treatment exist but rapid-acting insulin (regular) must be administered first, as decreases in the hyperglycemia must be achieved quickly. When blood sugar levels are lowered and maintained at 200−250 mg/dL for 4−10 hours, then Vetsulin® (porcine insulin zinc suspension) can be used. Evaluation of treatment When evaluating the regulation of insulin therapy, it is important to consider several areas including the evaluation of glycemia, urine monitoring, routine rechecks and glycated protein evaluations. Evaluation of the glycemia Creating a blood glucose curve is the most accurate way to evaluate glycemia in order to adjust the dose of Vetsulin. Indications for creating a blood glucose curve are: First, to establish insulin dose, dosing interval, and insulin type when beginning regulation. Second, to evaluate regulation especially if problems occur. Third, when rebound hyperglycemia (Somogyi effect) is suspected. Contraindications for creating a blood glucose curve are: Concurrent administration of drugs affecting glycemia. Presence of a known infection or disease. Stressed animal. The procedure is as follows: The most accurate way to assess response to management is by generating a blood glucose curve. Ideally, the first sample should be taken just prior to feeding Continue reading >>
Hyperkalemia (high Blood Potassium)
How does hyperkalemia affect the body? Potassium is critical for the normal functioning of the muscles, heart, and nerves. It plays an important role in controlling activity of smooth muscle (such as the muscle found in the digestive tract) and skeletal muscle (muscles of the extremities and torso), as well as the muscles of the heart. It is also important for normal transmission of electrical signals throughout the nervous system within the body. Normal blood levels of potassium are critical for maintaining normal heart electrical rhythm. Both low blood potassium levels (hypokalemia) and high blood potassium levels (hyperkalemia) can lead to abnormal heart rhythms. The most important clinical effect of hyperkalemia is related to electrical rhythm of the heart. While mild hyperkalemia probably has a limited effect on the heart, moderate hyperkalemia can produce EKG changes (EKG is a reading of theelectrical activity of the heart muscles), and severe hyperkalemia can cause suppression of electrical activity of the heart and can cause the heart to stop beating. Another important effect of hyperkalemia is interference with functioning of the skeletal muscles. Hyperkalemic periodic paralysis is a rare inherited disorder in which patients can develop sudden onset of hyperkalemia which in turn causes muscle paralysis. The reason for the muscle paralysis is not clearly understood, but it is probably due to hyperkalemia suppressing the electrical activity of the muscle. Common electrolytes that are measured by doctors with blood testing include sodium, potassium, chloride, and bicarbonate. The functions and normal range values for these electrolytes are described below. Hypokalemia, or decreased potassium, can arise due to kidney diseases; excessive losses due to heavy sweating Continue reading >>
Euglycemic Diabetic Ketoacidosis: A Predictable, Detectable, And Preventable Safety Concern With Sglt2 Inhibitors
The Case At Hand Recently, the U.S. Food and Drug Administration (FDA) issued a Drug Safety Communication that warns of an increased risk of diabetic ketoacidosis (DKA) with uncharacteristically mild to moderate glucose elevations (euglycemic DKA [euDKA]) associated with the use of all the approved sodium–glucose cotransporter 2 (SGLT2) inhibitors (1). This Communication was based on 20 clinical cases requiring hospitalization captured between March 2013 and June 2014 in the FDA Adverse Event Reporting System database. The scarce clinical data provided suggested that most of the DKA cases were reported in patients with type 2 diabetes (T2D), for whom this class of agents is indicated; most likely, however, they were insulin-treated patients, some with type 1 diabetes (T1D). The FDA also identified potential triggering factors such as intercurrent illness, reduced food and fluid intake, reduced insulin doses, and history of alcohol intake. The following month, at the request of the European Commission, the European Medicines Agency (EMA) announced on 12 June 2015 that the Pharmacovigilance Risk Assessment Committee has started a review of all of the three approved SGLT2 inhibitors (canagliflozin, dapagliflozin, and empagliflozin) to evaluate the risk of DKA in T2D (2). The EMA announcement claimed that as of May 2015 a total of 101 cases of DKA have been reported worldwide in EudraVigilance in T2D patients treated with SGLT2 inhibitors, with an estimated exposure over 0.5 million patient-years. No clinical details were provided except for the mention that “all cases were serious and some required hospitalisation. Although [DKA] is usually accompanied by high blood sugar levels, in a number of these reports blood sugar levels were only moderately increased” (2). Wit Continue reading >>
What Is Dka? - Definition, Symptoms & Treatment
Diabetic ketoacidosis is a life threatening condition for patients with diabetes. Learn the trigger for, the symptoms of, and the treatment for this terrifying condition in this lesson. What Is Diabetic Ketoacidosis? Everything that goes needs fuel. Your car needs gas, your laptop needs a battery, and you need food! When we eat food, not only are we enjoying something yummy, but we are fueling our body for all the thousands of tasks it is asked to do. We ingest whole food, and our digestive system breaks it down into different components - sugars, fats, proteins - that can be used as fuel. One of the most common types of fuel our bodies use is glucose (a sugar). Now, once the body has broken down the food into glucose, a hormone named insulin helps get the glucose from the bloodstream into the cells. Just like the hose and nozzle at the gas pump help you get gasoline into the tank of your car. Think if you pulled up to a gas station and there was no hose or nozzle; could you get gas? Of course not! And the same is true in our bodies. If there is no insulin, then the glucose is unable to enter the cells to be used as fuel. When the body lacks insulin, like in type 1 diabetes, it cannot use glucose as a fuel. So, it must use something else instead. The glucose is left in the bloodstream, and the body begins to breakdown fats. A byproduct of fat breakdown is ketones. Ketones are highly acidic. As the body continues to breakdown fats, the level of ketones continues to rise making the person's blood highly acidic. This leads to a condition known as diabetic ketoacidosis, commonly abbreviated as DKA. Symptoms of Diabetic Ketoacidosis The symptoms of DKA can be subtle and develop gradually over 24 hours or they can occur much more quickly if a patient is already suffering from Continue reading >>
