Fluid therapy: for heat exhaustion

Contributor(s): Elisa Mazzaferro, Claire Waters


  • Simple water deficit ’ evaporative losses.
  • See hyperthermia Hyperthermia.
  • Cool rapidly and give hypotonic fluid.
    Do not cool past 103 degreesF, as can overshoot and become hypothermic.
  • Give isotonic fluids first if cardiovascular collapse presents.
    For composition of solutions see Parenteral fluids comparison table Parenteral fluids comparison table.
  • Monitor PCV/TS as total protein/albumin may decrease with increased temperature and vasculitis. May need to add colloids such as hetastarch, dextrans or plasma if hypoproteinemia occurs.
