    Area of Science:

    • Veterinary Medicine
    • Comparative Anatomy
    • Physiology

    Background:

    • Understanding organ mass is crucial for physiological and pathological assessments in large canines.
    • Previous data on organ mass percentages in large dog breeds undergoing anesthesia and surgery is limited.

    Purpose of the Study:

    • To quantify the masses of major organs in large dogs following anesthesia and surgery.
    • To establish baseline organ mass percentages relative to total body mass in this specific canine population.

    Main Methods:

    • Post-mortem weighing of major organs (brain, gut, heart, kidneys, liver) in eight large dogs.
    • Calculation of organ masses as a percentage of total body mass.

    Main Results:

    Related Experiment Videos

  • Average total body mass was 29.6 kg.
  • Organ mass percentages: brain (0.28%), gut (2.61%), heart (0.73%), kidneys (0.40%), liver (2.36%).
  • Data presented as mean +/- standard deviation.

    • Conclusions:

    • Provides essential reference values for organ mass percentages in large dogs subjected to prolonged anesthesia and surgery.
    • Highlights the importance of considering physiological state when evaluating organ weights in veterinary clinical practice and research.
