Insights
Hard nut and melon seed skins are common pediatric bronchial foreign bodies, often lodged in the lower lobes. Bronchoscopic removal is effective, with basket forceps showing better results for larger objects.
Area of Science:
- Pediatric Pulmonology
- Bronchoscopy Techniques
- Foreign Body Aspiration
Context:
- Bronchial foreign bodies pose a significant risk in children.
- Early diagnosis and intervention are crucial for positive outcomes.
Purpose:
- To analyze the characteristics of pediatric bronchial foreign bodies.
- To evaluate the efficacy of bronchoscopic removal using grasping forceps.
Summary:
- A study of 246 children revealed hard nut and melon seed skins as the most frequent foreign bodies.
- The right lower lobe bronchi were the most common impaction site.
- Bronchoscopic removal was successful, with higher success rates for main bronchus foreign bodies and improved efficiency using basket forceps.
Impact:
- Provides insights into common pediatric bronchial foreign bodies and their locations.
- Highlights the effectiveness of bronchoscopy and specific forceps types in removal.
- Informs clinical practice for managing pediatric airway foreign bodies.
Objective:
To analyze the characters of bronchial foreign bodies in children and the utilization of bronchoscope in the treatment of bronchial foreign bodies.
Methods:
A total of 246 children were diagnosed with bronchial foreign bodies at our hospital during January 2000 until August 2009. Under local mucosal anesthesia, a bronchoscope was inserted through nasal cavity into bronchi. After identifying the site of foreign body, grasping forceps was guided through bronchoscope to remove the foreign body from airway.
Results:
Among 246 cases, hard nut and skin of melon seed were found (n = 230, 93.5%). The most common site of foreign body was in right lower lobe bronchi (n = 98, 38.9%). The average operative frequency was 1.9 +/- 1.3 and one-time extraction ratio 58.5% (n = 144). The one-time extraction ratio of patients with foreign body obstructed in main bronchi (91.1%), right middle lobe (60.0%) and right lower lobe (55.1%) was higher than others. The operation frequency of using basket grasping forceps (1.4 +/- 0.9) was lower than those using tooth type forceps (2.1 +/- 1.4). And the difference was significant (P = 0.000).
Conclusion:
For bronchial foreign body in pediatric patients, hard nut and skin of melon seed are the most common foreign bodies. The right and left lower lobe bronchi are the predilection site. Foreign body in main bronchus is the easiest to be removed by grasping forceps. For massive foreign bodies, basket grasping forceps fares better than tooth grasping forceps.

The Bronchial Tree
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...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
