Topic: Hypertonic solution


  
  Hypertonic - Wikipedia, the free encyclopedia
A solution that has a higher concentration of solutes than that in a cell is said to be hypertonic.
Saltwater is hypertonic to the fish that live in it.
The opposite of hypertonic is hypotonic, where the net movement of water is into the cell; the intermediate state is called isotonic, where there is no net movement of water.

 OUR EXPERIENCE IN THE TREATMENT OF BURN SHOCK BY HYPERTONIC LACTATED SALINE SOLUTION
Resuscitation with hypertonic lactate saline (HLS) with a sodium concentration of 250 mEq/l was first practised by Monafo in 1970, 1973, and 1984, by Moylan in 1973, by Shuji in 1977, and by Caldwell and Bowser in 1979, 1983, and 1985.
Hypertonic fluids (205-310 mEq/l Na+ or 410-620 mOsm) have been used successfully in burn injury to replenish and maintain plasma volume without having to infuse excessive quantities of water.14 Resuscitation with hypertonic salt solutions involves the administration of higher concentrations of sodium than in isotonic resuscitation.
Hypertonic salt solutions generating osmotic pressures of several thousand mm Hg in excess of normal have been known for many years to be effective in treating shock states by borrowing intracellular water to fill the extracellular space deficit because sodium does not cross into the cells.

The infusion of small volumes of hypertonic saline solution or hypertonic saline plus dextran-70 is remarkably effective in restoring adequate hemodynamic conditions after hypovolemic shock.
Significantly greater volumes of fluids were required to restore systolic pressure in the patients receiving isotonic saline solution than in the groups receiving hypertonic solution.
Infusion of 250 ml hypertonic saline solution in patients with severe hypovolemia was not related to any complications, nor did it affect mortality rates; it improved MAP significantly, acutely expanded plasma volume by 24%, and reduced significantly the volumes of crystalloids and blood required in their resuscitation.

 Transport Across Membranes
isotonic solution - is a solution where the solute concentration of the solution that the cell is in is the same as the solute concentration of the cell's cytoplasm.
If a cell is placed in a hypertonic solution (higher solute concentration outside the cell) water will leave the cell, the net movement of water is from the inside to the outside of the cell.
If a cell is placed in a hypotonic solution (lower solute concentration outside the cell) water will enter the cell, the net movement of water is from the outside to the inside of the cell.

The effect of the hypertonic solution applied for periods of 20 min was reversible (Fig.
While the effect of hypertonic solution on cell volume was reversible, even after a second application, activation of the inward current was totally blocked during a second hypertonic challenge and release of ATP, though still detectable, represented only 35 % of the amount of ATP released during the first hypertonic stimulus.
The hypertonic shock-activated inward current was completely reversible, but was blocked after a second hypertonic challenge, suggesting an association between the opening of the current and some disruption between the cytoskeleton and the plasma membrane.

 Cell Structure and Function
It is effected by the concentration of dissolved solutes in the external and internal environments of the cell.
The solutions surrounding the cell and ones that are internal consist of a solvent, which is water, and solutes, which are substance dissolved in the water.
Solutions that have more solute dissolved than another one are said to by hypertonic to the solution they are being compared to.

 Re: When is a cell flaccid compared to turgid compared to plasmolysed?
Hypertonic solution - cell less salty than surrounding solution, net water movement out of cell Isotonic solution - cell and surrounding solution equally salty, no net water movement Hypotonic solution - cell saltier than surrounding solution, net water movement into cell It depends on whether it is a plant or animal cell.
When considering effects of changing the external solution, the normal assumption is you are transferring a cell from its usual environment to a different environment.
If the solution is dilute enough, the cell may burst because it has no cell wall to prevent the cell membrane from stretching as the cell expands.

 THE USE OF ALKALINE HYPERTONIC SALINE SOLUTION FOR RESUSCITATION OF SEVERE THERMALLY INJURED PATIENTS (OUR EXPERIENCE)
Hypertonic saline solution (HSS) formulae were used for the treatment of hypovolaemic shock in the attempt to diminish the large volume of fluids which are needed for resuscitation.
With a hypertonic crystalloid solution fewer fluids were required, resulting in less peripheral oedema and pulmonary congestion, while at the same time maintaining greater intravascular volume and lessening the risk of hypovolaemic shock.
We regard the alkaline hypertonic saline solution formula as a good approach to prevent complications in severe thermally injured patients in the first 48 hours.

A solution that is hypertonic to a cell has a larger concentration of solute than the cell, and water will move out of the cell.
A solution that is isotonic to a cell has an equal concentration of solute than the cell, and there will be no net movement of water.
Once the solute is evenly distributed, there is no longer a concentration gradient, and there will be no net movement.
