    A new program helps calculate patient intravenous fluid and nutrient needs using a pocket calculator. It found that junior clinicians often provided too much water and insufficient nitrogen and energy for ill patients.

    Area of Science:

    • Medical Informatics
    • Clinical Nutrition

    Background:

    • Calculating 24-hour intravenous requirements for water, nitrogen, energy, and electrolytes is crucial for patient care.
    • Accurate calculation can be complex and prone to errors in clinical practice.

    Purpose of the Study:

    • To describe a program for calculating intravenous nutritional and fluid needs.
    • To compare calculator-generated recommendations with clinician-prescribed regimens.

    Main Methods:

    • Development of a program for a card-programmable pocket calculator.
    • Comparison of program outputs with intravenous feeding plans for 8 ill patients.

    Main Results:

    • The calculator program provides specific 24-hour intravenous requirements.

  • Comparison revealed that junior clinicians tended to prescribe excessive water and inadequate nitrogen and energy.

    • Conclusions:

    • The calculator program is a potentially useful bedside tool for determining intravenous feeding regimens.
    • Modifications may enhance its clinical applicability for calculating patient nutritional and fluid needs.
