normal saline solution (0.9% nacl) or nss is a crystalloid isotonic iv fluid that contains water sodium (154 meq/l) and chloride (154 meq/l). it has an osmolality of 308 mosm/l and gives no calories. it is called normal saline solution because the percentage of sodium chloride dissolved in the solution is similar to the usual concentration of sodium and chloride in the intravascular space. normal saline is the isotonic solution of choice for expanding the extracellular fluid (ecf) volume because it does not enter the intracellular fluid (icf). it is administered to correct extracellular fluid volume deficit because it remains within the ecf. - -normal saline is the iv fluid used alongside the administration of blood products. it is also used to replace large sodium losses such as in burn injuries and trauma. it should not be used for heart failure pulmonary edema and renal impairment or conditions that cause sodium retention as it may risk fluid volume overload.
