Ringer's lactate solution (RL), also known as sodium lactate solution and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. It may also be used to treat metabolic acidosis in cases other than those caused by lactic acidosis and to wash the eye following a chemical burn. It is given by injection into a vein or applied to the affected area.
Ringer’s lactate solution, or lactated Ringer’s solution, is a type of isotonic, crystalloid fluid further classified as a balanced or buffered solution used for fluid replacement. The contents of Ringer’s lactate include sodium, chloride, potassium, calcium, and lactate in the form of sodium lactate, mixed into a solution with an osmolarity of 273 mOsm/L and pH of about 6.5. In comparison, normal saline (NS) has an osmolarity of about 286 mOsm/L.
Ringer Lactate R Solution is especially useful for the control of excessive vomiting, diarrhoea, dehydration or in infectious diseases such as cholera. It is administered either through an intravenous fluid injection or through a process known as electrolyte therapy.
