Negative pressure pulmonary edema

Negative Pressure Pulmonary Edema [NPPE] or Post-Obstructive Pulmonary Edema [POPE] is one of the most life-threatening emergencies in anesthesia

Immediate diagnosis with NPPE leads to better outcome. Usually, it affects healthy young patients. It occurs after upper airway obstruction, such as laryngeal spasms, tumor, and infection; it follows strong inspiratory effort leading to low negative pressure in the lungs which results into fluid infiltration and precipitates interstitial and alveolar edema

We report a case of unusual presentation of Negative Pressure Pulmonary Edema during and after extubation, which highlights the importance of early recognition and timely intervention to prevent further deterioration
