Rapid correction of severe hyponatremia and control of subsequent overcorrection in operative hysteroscopy intravascular absorption syndrome: A case report.

The detection of OHIAS may be delayed under general anesthesia, and prior vigilance is important if the operation time is prolonged. In severe hyponatremia with an apparently rapid onset, such as OHIAS, a two-step correction process may be safe and useful: rapid correction followed by more gradual correction.
