DIABETIC KETOACIDOSIS Flashcards
These are all indicative of what condition?
- Hyperglycemia >250mg/dL
- Acidosis with blood pH less than or equal too 7.3
- Serum bicarbonate less than or equal to 15mEq/L
- Serum positive for ketones
DKA
What may be the initial manifestation of both type 1 or type 2 diabetes and commonly occurs with poor compliance in type 1 diabetes, particularly when episodes are recurrent?
Diabetic Ketoacidosis
What develops in type 1 and type 2 diabetes with increased insulin requirements during infection, trauma, myocardial infarction or surgery?
Diabetic ketoacidosis
What may develop in type 2 diabetes under severe stress such as sepsis or trauma and is a common serious complication of insulin pump therapy?
Diabetic ketoacidosis
What can present with the clinical findings below?
- may begin with a day or more of polyuria, polydipsia, marked fatigue, nausea and vomiting and, finally mental stupor that can progress to coma
- dehydration, possible stupor
- rapid deep breathing and a “fruity” breath odor of acetone
- Hypotension w/ tachycardia indicated profound fluid and electrolyte depletion
- mild hypothermia usually present, elevated or even a normal temp may suggest infection
- abdominal pain and tenderness in the absence of abdominal disease; conversely cholecystitis or pancreatitis may occur with minimal symptoms and signs
DKA
What is the initial management therapy for DKA?
Volume repletion
What is the fluid of choice in the volume repletion of DKA treatment?
lactated ringers
When glucose falls to ____ or less, use 5% glucose solutions to maintain blood glucose 200-300mg/dL while continuing insulin to clear serum ketones.
250mg/dL
Once improvement is noted in vitals and hyperglycemia and adequate urine output of at least ____ is ensured, iv fluids may be reduced to maintenance levels or discontinued if the patient is taking oral fluids well.
30-50mL/h
True or False
The cornerstone of therapy for acute hyperglycemia is restoration of intravascular volume and reperfusion of vital organs, especially the kidneys
True
Often potassium is elevated initially due to metabolic acidosis, however correction of acidosis and insulin-mediated transfer of potassium into the cells may cause what?
serum potassium rapidly falling and may require aggressive repletion
Fluid over load for the treatment of DKA needs to be avoided in patients with what?
Cardiac disease
Excessive fluid replacement (more than 5 L in 8 H) may contribute to what?
- respiratory distress syndrome
2. cerebral edema
True or False
Initially insulin plus fluid and electrolyte replacement is the mainstay of treatment for DKA
True
consult medical officer prior to insulin administration
What is the inital loading dose of insulin, followed by 0.1 unit/kg/h, continuously infused or given hourly as an SUBQ injection for the treatment of DKA?
0.15 unit/kg IV bolus
