What is diabetic keto acidosis caused by?

Insufficient insulin levels in the blood. Because of these low levels of insulin, glucose metabolism is an insufficient energy source, and the body shifts to metabolizing fatty acid's for energy. The byproducts of fatty acids when metabolized or Keytone bodies, which causes the blood to become more acidic than usual. And attempt to reverse the acidosis, the body begins to exhale excess carbon dioxide, which results in tachypnea accompanied by an increase depth and respiration. Known as Kussmaul respirations or air hunger. These ketones are excreted in the urine along with sodium and potassium, resulting in a more severe electrolyte disturbance. Even though some key tones are illuminated, more are produced then are excreted, and therefore the acidosis increases, causing various signs and symptoms.

What is a glucometer?

It is a tool that measures the amount of glucose in blood.

If hypoglycemia is prolonged, additional symptoms can occur like?

Lethargy, irritability, confusion, slurred speech, headache and aggressive or bizarre behaviors. This condition may be mistaken for an acute central nervous system event, sepsis, or psychiatric disease

Describe diabetic retinopathy

Progresses from the mild form characterized by increased vascular permeability to a more moderate form characterized by vascular closure. The most severe form results and growth of new blood vessels on the retina and the posterior surface of the vitreous. Macular Edema, characterized by retinal thickening from leaky blood vessels, can develop at all stages of retinopathy. Diabetics are also prone to cataracts and glaucoma. Early screening and strict glucose control or essential for preventing diabetic retinopathy.

Diabetes Mellitus Is it condition caused by

Reduction or absence of the production of insulin by the beta cells of the pancreas or defects of insulin receptors

Severe hypoglycemia or diabetic ketoacidosis (DKA) Hyperosmolar hyperglycemic state, and hypoglycemia

What is the risk of sensitivity using the inhalation route?

Some of the insulin maybe deposited in the mouth and throat rather than the lungs which reduces the amount of medication delivered to the patient

Treatment of diabetic keto acidosis

Step one- determine an accurate blood glucose level The necessary treatment for this patient is to lower blood glucose levels by providing insulin; however, the provision of insulin should be performed by a medical professional as the appropriate dosage is sensual to ensure the patient does not become hypoglycemic. If the clinician is unsure as to which diabetic emergency the patient is experiencing, then it is best to provide some form of glucose as it will not significantly harm a patient experiencing diabetic ketoacidosis and will benefit a patient suffering from severe hypoglycemia. In addition, fluid therapy is needed to reverse dehydration. Vital signs should be monitored to determine the severity of diabetic ketoacidosis

Patients with type one diabetes are dependent on what for survival?

Supplemental insulin

Signs and symptoms of diabetic ketoacidosis

Tachypnea accompanies by an increase depth in respiration (Kussmaul respirations) Alteration in mental status-drowsiness to coma Dehydration Poor skin turgor Warm, dry skin and mucous membranes Increased thirst Muscle weakness Severe fatigue Nausea Vomiting Blurred vision Fruity odor on breath Hypotension Tachycardia

The need for continuous immunosuppression to prevent rejection of the Islet cells or pancreas. There has been success with this treatment options though

What is the treatment for unconscious patients who are not able to take an oral carbohydrate?

The treatment of choice is glucagon (1 mg administered subcutaneously, intramuscularly, or intravenously), Which is effective at stimulating hepatic glycogenolysis

What are insulin pumps or continuous infusion therapy? And when were they introduced as a replacement for daily injections?

Their contact devices with an insulin filled syringe or cartridge that is attached to a subcutaneously inserted catheter. The catheter is usually changed every 4 to 6 days. Patients with insulin pumps still need to measure the glucose levels and adhere to a proper nutritional regimen.

What is hypoglycemia?

This condition used to be referred to as insulin shock, which essentially was severe hypoglycemia with a blood glucose level lower than 40 to 50 mg/dL. Usually occurs because of a missed meal or irregular eating, consumption of alcoholic beverages, or increased exercise without adjusting the insulin dosage. The brain is dependent on a continuous supply of glucose, so brain function is affected when glucose levels fall below a critical level

Describe diabetic ketoacidosis

This is not an emergency that a dental professional would likely encounter; however there is a chance that it would occur. Occurs in a diabetic who is not medicating or eating appropriately; that is why older adults and teenagers, particularly girls who have negative attitudes toward eating, often suffer from this disorder
