Serum potassium 7-8 mEq/L or
electrocardiographic changes
due to hyperkalemia

No Yes

Intravenous fluid therapy: • 30-50 mg/kg calcium gluconate (0.3-0.5 mL/kg of 10%
Give 0.9% NaCl at a rate adequate solution) slow IV with electrocardiographic
to rapidly correct volume depletion monitoring (watch for bradycardia, QRS widening, QT
interval prolongation, or premature ventricular
complexes)
• Then, consider either:
• 50% dextrose 1-2 mL/kg diluted IV, or
• Regular insulin (0.25-0.5 U/kg IV) and 2 g of dextrose
for each unit of insulin administered (2 g = 4 mL of
50% dextrose, diluted prior to administration, or
• Sodium bicarbonate 0.5-2 mEq/kg IV (8.4% solution =
84 mg/mL=1 mEq/mL)

Perform confirmatory tests:
• Abdominal paracentesis with comparison of fluid creatinine
and potassium to serum (in essentially all cases
of uroperitoneum, fluid [K] serum [K], and fluid
[creatinine] serum [creatinine])
• Contrast urethrography and cystography
• Excretory urethrography

Stable cardiovascular status,
normokalemia, and normal
acid-base status
No Yes

Consider peritoneal dialysis Surgical correction of urinary
catheter to drain abdomen tract rupture
until stable for surgery
