The sucrose lysis test uses an isotonic sucrose solution to lower the ionic strength of serum, which triggers the activation of the classic complement pathway, leading to the lysis of cells that are sensitive to complement. [6] In the sucrose lysis test, patient RBCs are washed and resuspended in a buffered sucrose solution. [7]
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).
Intravenous sodium bicarbonate is contraindicated in patients who are losing chloride, such as by vomiting. [9]Because of its sodium content, intravenous sodium bicarbonate should be used with great care, if at all, in patients with congestive heart failure and severe chronic kidney disease, where low sodium intake is strongly indicated to prevent sodium retention. [9]
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 ...
Balanced salt solutions are used for washing tissues and cells and are usually combined with other agents to treat the tissues and cells. They provide the cells with water and inorganic ions, while maintaining a physiological pH and osmotic pressure. [2] Sometimes glucose is added as an energy source and phenol red is used as a pH indicator.
Depiction of a red blood cell in an isotonic solution. A solution is isotonic when its effective osmole concentration is the same as that of another solution. In biology, the solutions on either side of a cell membrane are isotonic if the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.
Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride , potassium chloride , calcium chloride and sodium bicarbonate , with the last used to buffer the pH .
Ringer's lactate solution (RL), also known as sodium lactate solution, Lactated Ringer's (LR), and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. [1] It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. [2]
