1

Key features of DKA:

hyperglycemia

ketosis

acidosis

2

Clinical presentation of DKA:

polyuria

polydypsia

polyphagia

weakness

Kussmaul's respirations

N/V

hypotension --> Tachycardia

peripheral circulatory failure

3

Lab criteria for DKA:

Gluc > 250

pH 12

stupor/coma

4

5 key tx components for DKA:

Monitor

**FLUID resus

insulin/dextrose infusion (after gluc normalizes)

electrolyte repletion (watch for hyper K --> hypo K)

treat underlying cause

5

Monitoring tests for DKA in the ER:

gluc, lytes w/anion gap, Mag

BUN/Cr + GFR

B-hydroxybutyrate + serum ketones

UA

CBC

EKG

Infx cultures, CXR

Cardiac enzymes

6

Typical fluid deficit in DKA:

100 mL per kg

ex: 80 kg pt is down 8L !!!

7

Initial fluid resus type:

NS

**switch to D5W/.45% NS once gluc below 250

8

K in DKA:

hyper K at first

lower with insulin+gluc (watch out for hypo K)

**if lower than 3.3 initially, replace K first
