ABSTRACT

Negative pressure pulmonary edema (NPPE), a non-cardiogenic pulmonary edema, develops due to airway obstruction. Young, healthy, male patients, who have a lot of muscle mass that can lead to produce high negative intra-pleural pressure (athletes pulmonary edema syndrome, APS), are under the risk of developing NPPE. Usually, NPPE develops after extubation in patients who undergo endotracheal intubation however; there are some case reports showing that it can develop after laryngeal mask application (LMA) even in a less manner. The most possible reasons lead to airway obstruction during LMA use are biting of laryngeal mask tube, misplacement of tube, and laryngospasm. This case report presents a patient who undergoes LMA and develops NPPE due to laryngospasm during recovery from anesthesia.
