Discussion
Body contain 60 % of water form body weight . Total body water ( TBW ) distribute in the body in intracellular compartment ( ICF ) and extracellular compartment (ECF ). One third ( 1/3 ) of total body water is extracellular . Remaining two thirds ( 2/3 ) of total body water in intracellular space .
when infused 5 % dextrose , it leaves intravascular compartment rapidly and enter into cells .the fluid is distributed according to their contribution to total body water. Therefore 2/3 of 1000ml (666 ml ) in the intracellular compartment and 1/3 of 1000 ml ( 333ml ) in the extracellular compartment
