HYPERKALEMIA Flashcards
MANAGEMENT
First step of potassium > 5.5 mEq:
Get stat ECG, Tele, IV Access
Management if ECG changes OR K > 6.5
Stabilize:
10 mL (1 amp) calcium chloride
Shift:
2 amp D50 + 10 U insulin
Monitor glucose q 30 min
Repeat k at 60 min
THEN
Salbutamol 8 puff
50 - 150 mEq IV NaHC03 if acidotic
Eliminate:
Insert foley
Hypovolemic - IV bolus normal saline, NO diuretic
Hypervolemic - furosemide 40 - 80 mg IV
Sodium polystyrene sulfonate (Keyexalate) 50 g PO
Management if potassium if NO ECG change AND K > 5.5 and < 6.5
Shift:
2 amp D50 + 10 U insulin
Monitor glucose q 30 min
Repeat k at 60 min
THEN
Salbutamol 8 puff
Eliminate:
Insert foley
Hypovolemic - IV bolus normal saline, NO diuretic
Hypervolemic - furosemide 40 - 80 mg IV
Sodium polystyrene sulfonate (Keyexalate) 50 g PO
