Isotonic crystalloids help restore fluid balance by providing a solution that has a similar concentration of solutes as the body's cells. They are commonly used for fluid resuscitation in patients with dehydration, hypovolemia, or shock. Isotonic crystalloids can help replenish extracellular fluid volume, improve circulation, and support organ function.
If you meant an isotonic solution, an isotonic solution is a solution which contains the same concentration of solutes as the cell it is being compared to. This creates dynamic equilibrium, as the amount of solutes entering the cell and leaving the cell is the same.
Isotonic imbalance occurs when there is an abnormal concentration of solutes in body fluids, leading to an unequal distribution of water between compartments. This can be caused by factors such as excessive fluid loss (e.g., through vomiting, diarrhea, or sweating), inadequate fluid intake, or medical conditions affecting fluid regulation (e.g., kidney disease). Additionally, certain medications and hormonal changes can disrupt the balance of electrolytes and osmotic pressure, contributing to isotonic imbalance.
The concentration of glucose is typically higher in plasma (blood) compared to cerebrospinal fluid because glucose is actively transported from blood into the brain. Normal CSF glucose levels are around 60-70% of plasma glucose levels.
I read somewhere that it does not. perhaps because all of it is used up by the body cells.
0.9% saline is isotonic to blood.
Hypertonic solutions have more electrolytes....HYPER meaning greater/more/excessive. Hypotonic have the least electrolyes. Isotonic have the similar electroly (osmolality) as blood. Meaning if you give isotonic solutions, the fluid will saty in the vessels and not move fluids around. Hypertonic solutions will move water from the cells into the vessels (extracellualr) and hypotonic solution will move water from fluid from the vessels into the cells. Glucose is usually an iso or hypertonic solution, but there are different % of glucose in every solution. D5W is an isotonic solution.
Isotonic concentration
The concentration of glucose in intracellular fluid is typically around 1-10 mM (millimolar). This concentration can vary based on factors such as cellular metabolism, nutrient availability, and hormonal regulation.
Isotonic means that the concentration of solutes in the solution is the same as the concentration of solutes in the intracellular and extracellular fluid. This allows for balanced movement of water across cell membranes without causing them to shrink or swell.

Cerebrospinal fluid (CSF) mainly consists of water, electrolytes, glucose, and small amounts of protein. The cellular components of CSF include white blood cells, red blood cells, and occasionally some other types of cells, such as lymphocytes. The presence of these cells can indicate various conditions affecting the central nervous system.
Plasma is isotonic to glomerular filtrate, meaning that the concentration of solutes in the two fluids is similar. This isotonicity helps to maintain the balance of fluid and electrolytes in the body.
Two isotonic solutions are two solutions that have the same osmotic pressure. This term is generally used referring to solutions in a cell or body fluid.
