Successful early intervention in air embolism during hysteroscopy.

Hysteroscopy is used as a diagnostic tool for intrauterine pathology. Gas embolism with air or carbon dioxide is a rare but sometimes fatal complication of laparoscopy or hysteroscopy. We present a patient who developed pulmonary air embolism during hysteroscopy that caused a noncardiogenic pulmonary edema in the recovery room. This case report emphasizes that early intervention can prevent life-threatening events associated with pulmonary embolism during hysteroscopy. Pathophysiology of pulmonary gas embolism, as well as that of noncardiogenic pulmonary edema, is discussed. A protocol for the prevention, early detection, and management of this emergency is provided.
