DOI: 10.4103/0019-5359.49220 Postobstructive pulmonary edema (POPE) i s an uncommon bu t we l l -descr ibed complication of upper airway obstruction. [1-2] Two forms of POPE have been deÞ ned: POPE I is associated with sudden, severe upper airway obstruction, whereas POPE II follows surgical relief of chronic upper airway obstruction.[2] Among the numerous causes of POPE I Þ gures hanging.[2] H...

Acute airway obstruction is much more common in infants and children than in adults because of their unique anatomic and physiologic features. Even in young patients with partial airway occlusion, symptoms can be severe and potentially life-threatening. Factors that predispose children to airway compromise include the orientation of their larynx, the narrow caliber of their trachea, and their w...

Negative pressure pulmonary edema (NPPE) or postobstructive pulmonary edema (POPE) is a form of noncardiogenic pulmonary edema that results from the generation of high negative intrathoracic pressure needed to overcome upper airway obstruction 1. It typically develops rapidly and can be life-threatening if not diagnosed promptly. Following an episode of acute airway obstruction or the relief of...

This analysis was conducted to evaluate the prevalence of airway obstruction among Latino poultry processing workers. Data were collected from 279 poultry processing workers and 222 other manual laborers via spirometry and interviewer-administered questionnaires. Participants employed in poultry processing reported the activities they perform at work. Participants with forced expiratory volume ...

Earlier studies have shown that time and flow indices derived from tidal expiratory flow patterns can be used to distinguish the severity of airway obstruction. This study was designed to address two aspects of tidal expiratory flow patterns: 1) how do expiratory flow patterns differ between subjects with normal and obstructed airways; and 2) can a sensitive index of airway obstruction be deriv...

OBJECTIVES/HYPOTHESIS Airway obstruction is an uncommon presentation of unilateral laryngeal paralysis. We have observed two mechanisms of obstruction: arytenoid prolapse and inappropriate adduction of the paralyzed vocal fold. We evaluated arytenoid abduction (AAb) and recurrent laryngeal nerve (RLN) reinnervation as treatments for airway obstruction in patients with unilateral laryngeal paral...

BACKGROUND Previous data from the literature reported blunted perception of airway obstruction in severe asthmatics with near fatal asthma. Approximately 25% of patients with asthma are current smokers. AIM To determine whether there is an alteration in perception of airway obstruction during a non specific provocative challenge with methacholine in mild controlled asthmatics who smoke. MET...

INTRODUCTION Laryngotracheobronchitis is a rare, but in severe cases may lead to laryngeal edema progressing to complete closure of the subglottis within a few hours, without prompt treatment. CASE PRESENTATION We present the case of acute airway obstruction caused by laryngotracheobronchitis in a 6-year-old boy, initially misdiagnosed and treated as foreign body aspiration. The treatment of ...
