When would colloid solutions be administered to a patient? What is the intended effect of colloid solution administration? What are the most commonly used colloid solutions?

Solution

Colloid solutions to be administered to a patient during :-
Colloid solutions employed in intravenous therapy belong to a gaggle of volume expanders, and may be used for endovenous fluid replacement. Colloids preserve a high mixture pressure within the blood,and thus, they ought to in theory preferentially will increase the intravascular volume.

Effect of colloid solution administration :-
Plasma volume expanders, within the variety of mixture or crystalloid solutions, work to revive intravascular volume by increasing the oncotic pressure within the area of intravascular.

Water moves into the intravascular area, increasing the circulatory volume, that afterward will increase central ,rate of flow ,pressure leve ,blood pressure , urine output , stroke volume and capillary introduction.

These enhanced measurable values lead successively to the decrease of pulse rate, peripheral resistance and blood consistency.

colloid solutions are :-
Dextran
Albumin
Gelatins
Hetastarch
Plasma protein fraction
