    Infusion solution temperature stabilizes to room temperature within 1-4 hours, affecting rheological properties and infusion rates. Running infusions reach room temperature faster, with higher speeds reducing temperature differences.

    Area of Science:

    • Investigates the impact of temperature on the rheological properties of various intravenous (IV) solutions.
    • Focuses on fluid dynamics and thermal behavior of common medical infusions.

    Context:

    • Infusion solutions are stored at refrigerated temperatures (4-10°C) before administration.
    • Temperature significantly affects fluid viscosity and density, crucial for accurate infusion delivery.
    • Understanding temperature-related changes is vital for maintaining consistent infusion rates.

    Purpose:

    • To investigate the temperature behavior of various infusion solutions under static and dynamic (running) conditions.
    • To determine the time required for infusion solutions to reach room temperature.
    • To assess the influence of infusion speed on solution temperature.

    Summary:

    • Both static and running infusions approach room temperature over time, with significant temperature gradients observed in running infusions.

  • In static infusions, temperature equilibration takes 3-4 hours. In running infusions, the solution in the cannula reaches room temperature in about 1 hour, while the bottle remains ~10°C cooler.
  • Higher infusion rates reduce the temperature difference between the bottle and cannula.

    • Impact:

    • Establishes timelines for achieving stable rheological properties in infusion solutions.
    • Highlights the importance of considering infusion speed and duration for accurate drug delivery.
    • Provides data for optimizing infusion protocols and ensuring patient safety by managing temperature-dependent flow rates.
