acidosisFix elyte deficits Correct hyperglycemia |
|
|
1st step of DKA treatment |
Bolus 20ml/kg (10 in newborns) NSReassess - can give
2nd bolusWill improve hyperglycemia - increased GFR with improved renal perfusion |
|

Potassium repletion in DKA |
Depletion more evident when acidosis corrected Monitor
EKG while repleting30-40mEq/L KCl or KPhos |

Phosphate repletion |
in DKA Depletion becomes more evident when
acidosis correctedMonitor calcium during repletion |
|
|

(not hyperglycemia) is corrected |
