In which fluid compartment is the majority of water in the body and what is its primary composition?
- Intracellular
- majority of our total body water is locked within our cells in the intracellular compartment.
- Composed of high potassium and low sodium. The gradient is maintained by Na-K ATPase.
Which is the second largest fluid compartment in the body and what is its primary composition?
- Interstitial
- bathes the cells and occupies spaces such as pleural cavity and joint spaces. It absorbs and loses fluid to intracellular and intravascular compartments.
- Composed of high sodium (135 – 145 mmol/L and low potassium (3.5 – 5 mmol/L) identical to blood, but with a lower protein content.
What are the basic requirements for sodium, potassium and fluid per day?
Basic requirements:
Sodium → 2mmols/kg/day
Potassium → 1mmol/kg/day
Fluid→ 1-1.5 mls/Kg/hour (for adults approx. 1.5-2.5 L/day)
Where can the body lose fluid?
- GI - vomiting and diarrhoea. can also loose ↑↑Na + K

- Trauma - haemorrhage, drain, dialysis
What is a crystaloid?
Crystalloid solutions contain low molecular weight salts or sugars which dissolve completely in water and pass freely between the intravascular and interstitial compartments.

what is a colloid?
- Colloids contain larger molecular weight substances that do not dissolve completely and depending on their molecular size, structure and capillary permeability of he patient, remain for a longer period in the intravascular compartment than crystalloid solutions.
- You may need 2 – 3 times the volume of crystalloid to colloid to achieve the same vascular filling. they act as “a plasma expander in place of blood”.

- Blood investigations – should be performed daily on anyone receiving IV fluids, in particular electrolytes
- Urine biochemistry
