Fluid Losses

  • Insensible losses (respiratory) = 22 – 33 ml/k/day (0.9 – 1.3 ml/kg/hr)
    Sensible losses (Urinary) =26 – 44 ml/kg/day (1 – 1.8 ml/kg/hr)
    Total maintenance = 44 – 99 ml/kg/day (1.9 – 3.1 ml/kg/hr)
    Average = 2.5ml/kg/hr
  • Insensible loss is almost pure water (hypotonic fluid loss)
    Sensible loss is an isotonic fluid loss
  • Vomiting, diarrhea, osmotic diuresis are all isotonic losses
    Diabetes insipidus, panting, water deprivation are hypotonic losses
    Addison’s disease is a hypertonic loss

  1. Hello Dr. Bessler,

    I find your fluid therapy chart interesting. Often, I think of the IV fluid therapy my tiny 11.5 pound dog received and wonder how she didn’t go into cardiac arrest or literally blow apart internally. There were times on her chart that she received greater than 60mls/hour.
