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).
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 . [3] Ringer's lactate or Ringer's acetate is another isotonic solution often used for large-volume fluid replacement. The choice of fluids may also depend on the chemical properties of ...
NS: 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 ...
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.
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
Saline sprays are typically non medicated. A mist of saline solution containing sodium chloride is delivered to help moisturize dry or irritated nostrils. This is a form of nasal irrigation. They can also relieve nasal congestion and remove airborne irritants such as pollen and dust thereby providing sinus allergy relief.
Ringer's saline solution was invented in the early 1880s by Sydney Ringer, [4] a British physician and physiologist. Ringer was studying the beating of an isolated frog heart outside of the body. He hoped to identify the substances in blood that would allow the isolated heart to beat normally for a time. [19]
- delivery of an irrigant (usually normal saline) under direct pressure that is produced by an electrically powered device, useful in cleaning e.g. chronic wounds. [ 1 ] Look up lavage in Wiktionary, the free dictionary.
