Maintaining Adequate Intravascular Volume and Preventing Worsening Hyponatremia

In managing hyponatremia, it is important to assess the patient's volume status and provide appropriate fluid resuscitation if they are hypovolemic. In the case of hypervolemia or euvolemia, fluid restriction is recommended to prevent worsening hyponatremia. The use of normal saline or ringers lactate is preferred over hypotonic fluids to avoid rapid overcorrection of sodium levels. Monitoring postural vital signs can help determine the need for fluid boluses.
