Bronchoscopic extraction of aspirated foreign bodies in children
Insights
Pediatric foreign body removal using bronchoscopy is highly effective, with a 98% success rate. Advanced techniques like the Fogarty balloon and forceps ensure efficient extraction of aspirated objects in children.
Area of Science:
- Pediatric Pulmonology
- Interventional Pulmonology
- Pediatric Otolaryngology
Background:
- Aspiration of foreign bodies is a significant risk in children.
- Traditional methods of foreign body removal can be invasive and carry risks.
- Advancements in endoscopic technology have improved treatment options.
Purpose of the Study:
- To evaluate the efficacy of modern bronchoscopic techniques for extracting aspirated foreign bodies in pediatric patients.
- To assess the success rates and efficiency of specific extraction methods.
Main Methods:
- A retrospective review of pediatric patients undergoing bronchoscopic foreign body extraction over a five-year period.
- Utilized a pediatric ventilating bronchoscope with a Hopkins rod-lens system.
- Employed the Fogarty balloon technique for spherical objects and forceps for flat objects under general anesthesia.
Main Results:
- Successful extraction in 40 out of 41 children (98% success rate).
- 80% of foreign bodies were removed within the first or second bronchoscopic pass.
- The described techniques demonstrated high efficacy for various foreign body shapes.
Conclusions:
- Pediatric bronchoscopic foreign body extraction using advanced instruments and techniques is a safe and highly effective procedure.
- The Fogarty balloon and forceps techniques offer efficient removal of aspirated objects.
- This procedure requires specialized expertise from pediatric endoscopists and anesthesiologists due to potential cardiorespiratory risks.
Abstract:
New instruments and techniques have refined the art of extracting aspirated foreign bodies from children. During a five-year period at the University of New Mexico, Albuquerque, bronchoscopic extractions were successful in 40 of 41 children (98%). The extractions were performed with the patient under general anesthesia, using a pediatric ventilating bronchoscope that contained the Hopkins rod-lens system. Two methods of extraction were used, depending on the shape of the foreign object: the Fogarty balloon technique for spherical objects, and the forceps technique for flat objects. Using these techniques, most foreign bodies (80%) were removed on the first or second pass of the bronchoscope. Because bronchoscopic extraction is a delicate procedure and carries a risk of cardiorespiratory arrest, it should be performed by endoscopists and anesthesiologists who are skilled with this procedure in children.
