The osmolarity of human plasma is a measure of the total amount of dissolved ions and proteins in the blood. the normal range for plasma osmolarity is 285-295 mosm/l. whycan injection of a 600 mosm/l solution directly into a patient’s bloodstream be very painful and dangerous?
Question: The osmolarity of human plasma is a measure of the total amount of dissolved ions and proteins in the blood. the normal range for plasma osmolarity is 285-295 mosm/l. whycan injection of a 600 mosm/l solution directly into a patient’s bloodstream be very painful and dangerous?
Injecting a 600 mosm/l solution directly into a patient's bloodstream can be very painful and dangerous because it can cause an osmotic imbalance and damage to the red blood cells. When a solution with a higher osmolarity than the surrounding blood is injected into the bloodstream, water will move out of the blood cells and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. This can cause the cells to shrink and become dehydrated, which can impair their function and lead to hemolysis (rupture of the cells). In addition to the direct damage to the blood cells, the release of their contents into the bloodstream can cause further harm, such as kidney damage, blood clots, and other complications. Therefore, it is important to ensure that any solutions injected into the bloodstream are within the normal range of plasma osmolarity to avoid these risks.
