Summary

Hyponatremia is a common phenomenon seen in patients after aneurysmal SAH. Although there is no definitive cause to date, it is frequently thought to be the result of SIADH, CSW, or a combination of both. While the mechanism for SIADH is understood, there continues to be controversy in respect to CSW, though natriuretic peptides do appear to play a prominent role. Obtaining an adequate level of understanding of the pathophysiology of hyponatremia in the patient with SAH is key to differentiating between SIADH and CSW. Treatment varies for hyponatremia based on the presence of hypervolemia or hypovolemia. Nurses are valuable team members in recognizing the different findings and implementing the unique treatments so that outcomes for the patient with SAH are optimized and complications are avoided.
