Abstract:
Negative pressure pulmonary hemorrhage (NPPH) is a rare, life-threatening complication that develops after an acute upper airway obstruction. A 26 year old, healthy African-American man with no underlying lung disease developed negative pressure pulmonary edema and subsequently NPPH during recovery from general anesthesia for elective spine surgery. Diagnostic bronchoscopy confirmed an alveolar source of the bleeding. Clinical improvement was quick with supportive care in the medical intensive care unit.
