Negative pressure pulmonary edema

Negative-Pressure Pulmonary Edema.

Negative-pressure pulmonary edema (NPPE) or postobstructive pulmonary edema is a well-described cause of acute respiratory failure that occurs after intense inspiratory effort against an obstructed airway, usually from upper airway infection, tumor, or laryngospasm. Patients with NPPE generate very negative airway pressures, which augment transvascular fluid filtration and precipitate interstit...

Recurrent negative pressure pulmonary edema.

An African-American man, aged 34 years, underwent an elective uncomplicated right wrist laceration repair while under general anesthesia. Following extubation, the patient developed hypoxemia, tachypnea, shortness of breath, pulmonary rales, frothy sputum, decreased oxygen saturation, and evidence of upper airway obstruction. Chest radiograph showed pulmonary edema. The patient was diagnosed wi...

Acute postoperative negative-pressure pulmonary edema.

To the Editor: In their case study of negative-pressure pulmonary edema (NPPE), Krodel et al. repeat the oft-cited idea that diuretics should be included in the therapies for this condition. They refer to using furosemide in the postanesthesia care unit for NPPE, which occurred as a result of laryngospasm on emergence. The authors do acknowledge that diuretics are not universally recommended fo...

Acute post-tonsillectomy negative pressure pulmonary edema

197 oropharynx to the rectum, and the duodenum is most frequently affected, followed by the stomach, esophagus and colon (1,2). Kaposi's sarcoma is about 300 times more common in AIDS patients than in those with other immunodeficiency types, and generally occurs in the setting of CD4 count below 150–200 cells/ mm 3(1). The diagnosis is made by means of digestive endoscopy and biopsy. The classi...
