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).
Flushing with saline should be painless if the cannula is in its proper place, although if the saline is not warmed there may be a cold sensation running up the vein. A painful flush may indicate tissuing or phlebitis and is an indication that the cannula should be relocated. [1] Solutions other than normal saline may be used.
Saline solution normally contains 0.9% sodium chloride. This article walks you through application instructions based on the intended use.
The types of intravenous fluids used in fluid replacement are generally within the class of volume expanders. Physiologic saline solution, or 0.9% sodium chloride solution, is often used because it is isotonic, and therefore will not cause potentially dangerous fluid shifts. Also, if it is anticipated that blood will be given, normal saline is ...
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.
Medications may be mixed into the fluids mentioned above, commonly normal saline, or dextrose solutions. [4] Compared with other routes of administration, such as oral medications, the IV route is the fastest way to deliver fluids and medications throughout the body. [5]
Intravenous therapy is a type of parenteral medication. IV iron infusion is a method of delivering a mixed solution of iron and saline from a drip through a needle directly into the vein and bloodstream. [14] The procedure takes place in a medical clinic and may take several hours depending on the iron preparation that has been prescribed. The ...
It is the method of choice for patient-controlled analgesia (PCA), in which repeated small doses of opioid analgesics are delivered, with the device coded to stop administration before a dose that may cause hazardous respiratory depression is reached. Total parenteral nutrition usually requires an infusion curve similar to normal mealtimes.
