Which solution is used for fluid replacement during hemodialysis treatment?

The appropriate solution for fluid replacement during hemodialysis treatment is 0.9% normal saline. This solution is isotonic, which means it has the same osmotic pressure as blood. When fluid replacement is needed during hemodialysis, it’s essential to maintain the correct balance of electrolytes and fluids in the patient's system.

0.9% normal saline is commonly used because it effectively replaces lost fluids without altering the osmotic balance. It helps ensure that patients do not become hypovolemic (low blood volume) during the procedure. Maintaining adequate fluid balance is particularly crucial during hemodialysis, as patients typically experience fluid removal throughout the treatment. Therefore, using an isotonic solution like 0.9% normal saline assists in achieving optimal fluid homeostasis, preventing potential complications associated with fluid shifts.

Other solutions, such as 0.45% normal saline, are hypotonic and may lead to cellular swelling or hemolysis by causing fluid to shift into cells. Solutions like 5% dextrose in normal saline and 5% dextrose in water alter osmotic pressure and may not provide the necessary electrolyte balance required during hemodialysis. Hence, the use of 0.9% normal
