1
Q

Key features of DKA:

A

hyperglycemia

ketosis

acidosis

2
Q

Clinical presentation of DKA:

A

polyuria

polydypsia

polyphagia

weakness

Kussmaul’s respirations

N/V

hypotension –> Tachycardia

peripheral circulatory failure

3
Q

Lab criteria for DKA:

A

Gluc > 250

pH 12

stupor/coma

4
Q

5 key tx components for DKA:

A

Monitor

**FLUID resus

insulin/dextrose infusion (after gluc normalizes)

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

treat underlying cause

5
Q

Monitoring tests for DKA in the ER:

A

gluc, lytes w/anion gap, Mag

BUN/Cr + GFR

B-hydroxybutyrate + serum ketones

UA

CBC

EKG

Infx cultures, CXR

Cardiac enzymes

6
Q

Typical fluid deficit in DKA:

A

100 mL per kg

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

7
Q

Initial fluid resus type:

A

NS

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

8
Q

K in DKA:

A

hyper K at first

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

**if lower than 3.3 initially, replace K first
