Rare Cause of Severe Dyspnea After Tracheotomy-Negative Pressure Pulmonary Edema

Abstract

Deep neck infections are serious conditions and can present with acute upper airway obstruction. Our priority in the treatment is to ensure airway safety, and tracheotomy may be needed to overcome the upper airway obstruction. Unceasing dyspnea after tracheotomy should suggest serious pulmonary pathologies in patients with upper airway obstruction due to deep neck infection. Acute/chronic obstruction resolved after tracheotomy or upper respiratory tract surgical procedures of obstructive sleep apnea patients can turn into severe dyspnea with pulmonary edema. In this report, we present a 46-year-old male patient with negative pressure pulmonary edema as a complication of tracheotomy. The tracheotomy was performed due to severe upper airway obstruction secondary to a deep neck infection. The importance of early diagnosis and prompt treatment of this rare entity after unceasing dyspnea despite tracheotomy is discussed in the light of the current literature.
