Hypertonic Saline which contains sodium chloride works in regulating ICP, intravascular volume and cardiac output without causing significant diuresis, but there are theoretical side effects ranging from neurological complications to subdural hematoma. Hypertonic saline solution has been choice of neuro critical care for the past few years. [1]
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).
Eye drops usually contain saline to match the salinity of the eye. Drops containing only saline and sometimes a lubricant are often used as artificial tears to treat dry eyes or simple eye irritation such as itching or redness. Eye drops may also contain one or more medications to treat a wide variety of eye diseases.
A hypertonic solution has a greater concentration of non-permeating solutes than another solution. [2] In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane ; a solution outside of a cell is called hypertonic if it has a greater ...
Hypertonic saline can improve ICP by reducing the amount of cerebral water (swelling), though it is used with caution to avoid electrolyte imbalances or heart failure. [ 10 ] [ 100 ] [ 101 ] Mannitol , an osmotic diuretic , [ 10 ] appears to be as effective as hypertonic saline at reducing ICP; [ 102 ] [ 103 ] [ 100 ] [ 104 ] however, some ...
While they may start out hypertonic they become hypotonic solutions as the sugar is metabolised. [5] Versions are also available mixed with saline. [3] Dextrose solutions for medical use became available in the 1920s and 1930s. [6] [7] It is on the World Health Organization's List of Essential Medicines. [8]
Mannitol is a type of sugar alcohol used as a sweetener and medication. [5] [6] It is used as a low calorie sweetener as it is poorly absorbed by the intestines. [5]As a medication, it is used to decrease pressure in the eyes, as in glaucoma, and to lower increased intracranial pressure.
With the eye generally profusely watering, the type of tears being produced have little adhesive property. Water or saline eye drops tend therefore to be ineffective. Rather a 'better quality' of tear is required with higher 'wetting ability' (i.e. greater amount of glycoproteins) and so artificial tears (e.g. viscotears) are applied frequently.
