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 ...
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.
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]
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 ...
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 ...
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 ...
Water for injection is water of extra high quality without significant contamination. [1] A sterile version is used for making solutions that will be given by injection. [2] Before such use other substances generally must be added to make the solution isotonic. [3] Isotonic solutions containing water for injection can be given by injection into ...
The presence of cerebral edema, or other moderate to severe symptoms, may necessitate intravenous hypertonic saline administration with close monitoring of the serum sodium levels to avoid overcorrection. [2] SIADH was originally described in 1957 in two people with small-cell carcinoma of the lung. [3]
