Hyponatremia and signals the kidney to bring back sufficient solute-free water from the fluid in the kidney tubules to dilute the serum sodium back to normal, and this turns off the osmoreceptors in the hypothalamus. Also, thirst is stimulated. Normally, when mild hyponatremia begins to occur, that is, the serum sodium begins to fall below 135 mEq/L, there is no secretion of ADH, and the kidney stops returning water to the body from the renal tubule. Also, no thirst is experienced. These two act in concert to raise the serum sodium to the normal range. Hyponatremia occurs 1) when the hypothalamic-renal
Human serum albumin trauma, burns and surgery patients. A Cochrane systematic review of 37 trials found no evidence that albumin, compared with cheaper alternatives such as saline, reduces the risk of dying. Human serum albumin has been used as a component of a frailty index. It has not been shown to give better results than other fluids when used simply to replace volume, but is frequently used in conditions where loss of albumin is a major problem, such as liver disease with ascites. Human serum albumin may be used to potentially reverse drug/chemical toxicity by binding to free drug/agent. (Tatlow, D, Poothencheri, S,
