Negative pressure pulmonary edema after peritonsillar abscess tonsillectomy

摘要

We report on a 19-year-old patient who developed negative pressure pulmonary edema (NPPE) with respiratory insufficiency following abscess tonsillectomy. NPPE is an unpredictable and life-threatening postoperative complication characterized by respiratory insufficiency. It may arise immediately after extubation or later in the postoperative period. NPPE is frequently observed after laryngospasm or in combination with space-occupying lesions in the pharynx and larynx. Treatment comprises the immediate correction of hypoxemia, preferably by noninvasive respiratory support using continuous positive airway pressure (CPAP), although in some cases reintubation is necessary.
