Successful treatment of acute respiratory distress syndrome after hysterectomy for life-threatening atonic bleeding by inhaled nitric oxide

Abstract

We report a case of a 33-year-old female who developed severe acute respiratory distress syndrome (ARDS) after emergency hysterectomy for life-threatening atonic bleeding. A marked decline in pulmonary oxygenation was observed during the surgery, which led to a diagnosis of ARDS. Following admission to the intensive care unit, hypoxia became critical, with a PaO(2)/F(I)O(2) value of 52 even after recruitment maneuvers. Inhaled nitric oxide (NO 10 ppm) was administered to the patient as a rescue treatment, resulting in a gradual but dramatic improvement in pulmonary oxygenation. Although several randomized trials have failed to confirm the beneficial effects of NO on morbidity in patients with ARDS, NO administration is worth consideration as treatment prior to invasive treatments, such as extracorporeal membrane oxygenation, for patients with acute lung injury/ARDS.
