Saline solution for irrigation. Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per liter. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
Normal saline (NS) is the commonly used term for a solution of 0.9% w/v of NaCl, about 300 mOsm/L. [4] Less commonly, this solution is referred to as physiological saline or isotonic saline, neither of which is technically accurate.
normal saline: NSA: no significant abnormality NSAID: nonsteroidal antiinflammatory drug: NSBB: Non-selective beta blocker: NSCC: Non-squamous-cell carcinoma NSCLC: non–small cell lung carcinoma: NSD: normal spontaneous delivery (see childbirth) NSE: neurospecific enolase: NSIP: Non-specific interstitial pneumonia: NSR: normal sinus rhythm: NST
This is due to urea entering the cell down its concentration gradient, followed by water. The osmolarity of normal saline, 9 grams NaCl dissolved in water to a total volume of one liter, is a close approximation to the osmolarity of NaCl in blood (about 290 mOsm/L). Thus, normal saline is almost isotonic to blood plasma.
Plasma osmolarity of some reptiles, especial those from a freshwater aquatic environment, may be lower than that of mammals (e.g. < 260 mOsm/L) during favourable conditions. Consequently, solutions osmotically balanced for mammals (e.g., 0.9% normal saline) are likely to be mildly hypertonic for such animals.
Annual mean sea surface salinity for the World Ocean. Data from the World Ocean Atlas 2009. [1] International Association for the Physical Sciences of the Oceans (IAPSO) standard seawater. Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity).
The typical composition of a banana bag is 1 liter of normal saline (sodium chloride 0.9%) with: [2] Thiamine 100 mg; Folic acid 1 mg; Multivitamin for infusion (MVI), 1 ampule; Magnesium sulfate 3 g; The solution is typically infused over four to eight hours or as per physician's orders.
Normal saline is least irritating to the colon. Like plain water, it simply functions mechanically to expand the colon, but having a neutral concentration gradient, it neither draws electrolytes from the body, as happens with plain water, nor draws water into the colon, as occurs with phosphates. Thus, a salt water solution can be used when a ...
