Tonicity. In chemical biology, tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane. Tonicity depends on the relative concentration of selective membrane-impermeable solutes across a cell membrane which determine the direction and extent of ...
none. UNII. 5SL0G7R0OK. Intravenous sugar solution, also known as dextrose solution, is a mixture of dextrose (glucose) and water. [ 1 ] It is used to treat low blood sugar or water loss without electrolyte loss. [ 2 ] Water loss without electrolyte loss may occur in fever, hyperthyroidism, high blood calcium, or diabetes insipidus. [ 2 ] It is ...
Oral rehydration therapy. An oral rehydration solution (250ml) prepared according to WHO formula. Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea. [1] It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. [1]
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
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 ...
A red blood cell in a hypertonic solution, causing water to move out of the cell. Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.
Intravenous ascorbic acid. Intravenous sodium bicarbonate. Intravenous sugar solution. Intravenous therapy.
Dry skin, eyes or lips. Fatigue. Less frequent urination. A person experiencing mild hypertonic dehydration may feel tired, thirsty, or restless. As the imbalance in the blood becomes more severe ...
