what kind of fluid is normal saline
The most commonly used crystalloid fluid is normal saline, a solution of sodium chloride at 0.9% concentration, which is close to the concentration in the blood (isotonic). Ringer's lactate or Ringer's acetate is another isotonic solution often used for large-volume fluid replacement.ormal saline (NS) is the commonly used term for a solution of 0.9% w/v of NaCl, about 300 mOsm /L. Less commonly, this solution is referred to as physiological saline or isotonic saline, neither of which is technically accurate.
