What can excessive sodium intake through IV fluids lead to?

Excessive sodium intake through IV fluids can lead to hypernatremia, which is a condition characterized by an elevated level of sodium in the blood. When large volumes of sodium are administered, it disrupts the normal balance of electrolytes and can cause the body's osmotic balance to shift. This results in cellular dehydration as water shifts out of cells to dilute the excess sodium in the extracellular fluid.

Hypernatremia can have several detrimental effects on the body, including symptoms like increased thirst, neurological changes, and in severe cases, it can lead to seizures or coma. Recognizing the signs and managing sodium levels are crucial components of fluid therapy in order to prevent complications associated with hypernatremia. Thus, monitoring the administration of IV fluids carefully to manage sodium levels is vital in clinical practice.
