A: Isotonic crystalloid solution Lactated Ringers solution It is a solution that is isotonic with blood and intended for intravenous administration. It is grouped with intravenous fluids that are known as crystalloids - which include saline and dextrose solutions compared to the colloids which contain larger molecules such as dextran, hydoxyethyl starch, polyvinylpyrrolidone or gelatin polymers Haemaccel. It is very similar, though not identical to, Hamanns Solution which has slightly different ionic concentrations One litre of lactated Ringers solution contains: 130 mEq of sodium ion 130 mmolL; 109 mEq of chloride ion 109 mmol L; 28 mEq of lactate 28 mmolL; 4 mEq of potassium ion 4 mmolL; 3 mEq of calcium ion 1.5 mmolL Although its pH is 6.5, it is an alkalizing solution.
