Alcohol withdrawal Flashcards
Define Diabetic ketoacidosis (DKA)
Acute complication of Diabetes
Lack of insulin which causes lived to believe they are starving -> goes into Ketoacidosis pathway-not efficient
Will cause death quite quickly
Define as academia, Hyperglycemia and Ketoaneamia
severe DKA if ph<7.1, K low, GCS <12, Ketones >6, etc
Aetiology and risk factors of DKA
Lack of insulin causes liver to believe its out of sugar-(can’t get in cells without insulin)-ketoacidosis pathway-
Risk factors
Inadequate DM monitoring
Most typical trigger is Infections-systemic response to increase glucose
MI can cause DKA via counter regulatory Hormones
Epidemology of DKA
More and more common In type 2d as they get pancreatic failure-used to be rare AF
even T1dm increasing
about 20-per 100 person with diabetes
Symptoms and signs of DKA
Drowsiness, vomiting and dehydration in T1DM (not t2DM)
Adbominal pain
Hyperventilation (cause of acidosis)
Reduced conciousness
Hypothermia
Acetone smell in breath
Investigations for DKA
ECG-Weird T waves, evidence of hypokalaemia (u wave)(or hyper (peaked T))
, CXR-can have oedema
Dipstick-expect ketoneuria
Bloods-regular, high BM, high Ketone, low K+, low Na
VBG-metabolic acidosis (maybe compensated)
Lactate
care-
not all ketone=ketoacidosis
plasma glucose not always raised
serum amylase might be high
Management of DKA
Insulin immediately-monitor falling ketones Check for K+ replacement -avoid hypokalaemia (fluids wth it) Ensure no hypoglycemia Ensure no Hypokalemia Avoid hypo bicarb
Complications of DKA
Cerebral Oedema-if sudden CNS drop get help Aspiration Pneumonia Hypokalaemia Hypomagnesium, hypophosphatmia thromboembolism
Prognosis of DKA
Mortality of DKA has dropped dramatically
