Tracheobronchial foreign bodies in adults

|April 15, 1990
Summary
Adult tracheobronchial foreign body aspiration, though rare, requires high clinical suspicion. Bronchoscopy is generally effective for diagnosis and removal, with rigid bronchoscopy showing higher success rates.
Area of Science:
- Pulmonology
- Emergency Medicine
- Otolaryngology
Background:
- Tracheobronchial foreign body aspiration is uncommon in adults but can present in diverse clinical scenarios.
- Impaired airway protective mechanisms, including neurologic disorders or substance use, are identified predisposing factors.
Purpose of the Study:
- To delineate the clinical spectrum of tracheobronchial foreign body aspiration in adults.
- To assess predisposing conditions, evaluate bronchoscopy efficacy, and determine outcomes and complications.
Main Methods:
- Retrospective analysis of 60 consecutive adult patients (age >16) undergoing bronchoscopic evaluation for suspected foreign body aspiration.
- Data collected from a tertiary care, referral-based medical center.
Main Results:
- Bronchoscopy identified foreign bodies in 59 of 60 patients, with successful removal attempted in 57.
- Rigid bronchoscopy demonstrated higher success rates (43/44) compared to flexible fiberoptic bronchoscopy (14/23), particularly in cases where fiberoptic failed.
- Complications were infrequent and minor; bronchiectasis occurred in 3 patients with prolonged impaction.
Conclusions:
- Tracheobronchial foreign body aspiration in adults necessitates a high index of clinical suspicion for timely diagnosis.
- Bronchoscopic removal is typically successful, with rigid bronchoscopy being a highly effective method.

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

01:17Pulmonary Cycle: Exhalation
5.5K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
