Question

Intravenous (IV) fluids are given to patients to replace lost solutes and/or fluids.

If a person is dehydrated, which type of solution (Hypotonic/Isotonic/Hypertonic) would replace intracellular fluid lost from cells? Explain. 2) Which type of solution would replace extracellular fluid caused by blood loss? Explain.

2) Which type of solution would replace extracellular fluid caused by blood loss?  Explain.

Answer 1

For treatment of severe dehydration, hypotonic solutions (57. dextrose in water, atel 0-20% 0-2% sodium chloride in 57. dextrose in water & 0.45% sodium chloride in water) are recommended as l.v resuscitation fluids. Fluid When there is loss of water from cells cells begin to shovel. Hence, hypotonic solution is administed to treat this type of dehydeation 2) To treat extracellular fruid lass due to blood loss – isotonic solutions would be used as treatment . During blood loss, the extracellular funds & solutes. are both lost in proportional amounts - hence there is isotonic fluid loss. The fluid deficits will be restricted to the extracellular space

and will involve no fluid shifts between compartments Isotonic fluid - eg. lactated singers or normal saline solution .. Normal saline is the only fluid used in conjunction with blood product administration Lactate Ringee is the most similar to blood plasma concentration. & can be used for acute blood loss.
