Diabetic ketoacidosis is a serious complication of diabetes mellitus that occurs when uncontrolled blood sugar rises and the body can’t produce enough insulin to use the glucose. When this happens, the body begins to break down fat as energy which produces a build-up of acid in the bloodstream called ketones. This is a serious life-threatening condition that occurs most often in Type I diabetics
Ketoacidosis can occur when diabetic patients experience emotional or physical stress such as with bacterial infections (UTI, etc), prolonged vomiting, surgery or when they miss doses of insulin. Alcohol and drug abuse in a diabetic patient can also cause the body to produce ketones that poison the blood.
Maintain blood glucose level within the target range, maintain normal fluid balance
Consistently high blood glucose levels, over 400 mg/dL, are the primary indicator of ketone production. Monitor glucose and intervene with prescribed insulin as appropriate to reduce glucose levels and prevent further ketone production.
Excess blood glucose can cause nausea and vomiting resulting in electrolyte imbalances. These electrolyte deficiencies can lead to further complications and cardiac arrhythmias.
DKA is often the result of an underlying infection such as a common cold, flu or bacterial infection like pneumonia or urinary tract infections. Assess for fever and other symptoms of infection and administer antibiotics as necessary.
Medications may be given to lower the blood glucose level in order to prevent further production of ketones or to manage symptoms of vomiting and underlying infection.
Vomiting and frequent urination can cause a deficiency in fluid volume, thus leading to a decreased circulatory volume. This will be evident by low blood pressure and tachycardia
Fatigue and weakness are common due to the cells inability to use glucose to produce energy, also following vomiting, and in cases of dehydration.
Maintaining a high blood glucose level, missing doses of insulin or being sick can cause ketones to form in the blood. Educate patients on healthy diet and lifestyle to prevent DKA. Teach patients and caregivers of the warning signs / symptoms of DKA.
