Postobstructive Negative Pressure Edema Associated with Pulmonary Hemorrhage in an Intubated Patient During General Anesthesia: One Sporadic Case Report and Literature Review

Negative pressure pulmonary edema accompanied by hemorrhage as a manifestation of upper airway obstruction secondary to lung cancer is an uncommon problem that is potentially life-threatening. This report presents a case of significant pulmonary hemorrhage and negative pressure pulmonary edema in an intubated patient during general anesthesia. Bronchoscopy showed tumor rupture with bleeding in the right lower lung lobe. We believe that in our case, pulmonary bleeding was due to disruption of the tumor capillaries during general anesthesia. Early diagnosis of pulmonary edema is very important because it affects the patient's postoperative morbidity and mortality. We discuss the possible causes and therapeutic approach, and we briefly review of literature.
