Urea Cycle Disorder Ammonia Crisis Management Calculator

Calculates ammonia scavenger dosing (sodium benzoate, sodium phenylacetate/phenylbutyrate) and emergency glucose infusion rates for urea cycle disorder hyperammonemic crises based on weight and severity.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates ammonia scavenger dosing (sodium benzoate, sodium phenylacetate/phenylbutyrate) and emergency glucose infusion rates for urea cycle disorder hyperammonemic crises based on weight and severity

Each component has a specific meaning:

  • Weight — The weight recorded for the scenario being assessed.
  • Severity — The severity recorded for the scenario being assessed.

Note: Interpret the ucd ammonia crisis result against the thresholds and context described above.

How to Use

Enter the weight, severity for the scenario you are assessing. Calculates ammonia scavenger dosing (sodium benzoate, sodium phenylacetate/phenylbutyrate) and emergency glucose infusion rates for urea cycle disorder hyperammonemic crises based on weight and severity. Use the ucd ammonia crisis result to inform your calculation.
