| absolute dehydration | Actual water deficit as measured by a difference from the normal or from a given water content. (05 Mar 2000) |
|---|---|
| relative dehydration | Water deficit relative to content of solutes contributing effective osmotic pressure; a state of increased effective osmotic pressure of body fluids. (05 Mar 2000) |
| glucose solution, hypertonic | Solution that is usually 10 percent glucose but may be higher. An isotonic solution of glucose is 5 percent. (12 Dec 1998) |
| voluntary dehydration | That physiologic lag or deficit that results when sensations of thirst are not strong enough to bring about complete replacement of water loss, as in rapid sweating. (05 Mar 2000) |
| saline solution, hypertonic | Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g nacl in 100 ml purified water). (12 Dec 1998) |
| hypertonic | Of a fluid, sufficiently concentrated to cause osmotic shrinkage of cells immersed in it. Note that a mildly hyperosmotic solution is not necessarily hypertonic for viable cells, that are capable of regulating their volumes by active transport. See: hypotonic, isotonic. (18 Nov 1997) |
| hypertonic bladder | A bladder with poor compliance. (05 Mar 2000) |
| hypertonic solution | Any solution which has a higher osmotic pressure than another solution (that is, has a higher concentration of solutes than another solution). A solution which contains a higher concentration of solutes than the cells that it is bathing, so that water is drawn out of the cells and into the solution by osmosis. A hypertonic solution is the opposite of a hypotonic solution. (09 Oct 1997) |
| hypertonic solutions | Solutions having a higher osmotic pressure than blood, or another solution with which they are compared. (12 Dec 1998) |
| dehydration | The condition that results from excessive loss of body water. Synonym: anhydration, deaquation, hypohydration. Origin: L. De = away, Gr. Hydor = water (18 Nov 1997) |
| dehydration-condensation reaction | The joining of two molecules to each other with the release of a water molecule in the process. Compare: hydrolysis. (09 Oct 1997) |
| dehydration fever | An elevation of temperature in infants after reduction of fluid intake, diarrhoea, or vomiting; probably caused by reduced available body water, with reduced heat loss by evaporation; an analogous condition in adults is seen when exertion is continued in the face of dehydration. Synonym: dehydration fever, exsiccation fever, inanition fever. (05 Mar 2000) |
