Pulmonary edema secondary to postextubation laryngospasm is a potentially life-threatening problem, demanding early diagnosis and prompt treatment. We believe that this problem has been grossly underestimated in its incidence, as only seven adults have been reported in the English literature, whereas seven adults have been observed at our institution in only a 24 month period. All were young, healthy, athletic adult males (average weight, 218 pounds) who underwent relatively minor, uncomplicated surgical procedures under general anesthesia. ⋯ The etiology of pulmonary edema following upper airway obstruction represents an interplay between several factors: cardiogenic and neurogenic mechanisms, as well as hypoxia contribute. In this group, excessive negative intrathoracic pressure generated by forced inspiration against a closed glottis is the most likely, consistent, and logical explanation. This study suggests that young, healthy, athletic males may be at increased risk for this complication.(ABSTRACT TRUNCATED AT 250 WORDS)
