Insights
A modified Broncho-Cath Right adapter with a laryngeal mask airway improves ventilation and safety for pediatric tracheobronchial foreign body removal. This technique is safe and effective for clinical use.
Area of Science:
- Pediatric Anesthesiology
- Respiratory Medicine
- Medical Device Innovation
Background:
- Tracheobronchial foreign bodies pose significant risks in children.
- Effective ventilation strategies are crucial during removal procedures.
Purpose of the Study:
- To evaluate the safety and efficacy of a modified Broncho-Cath Right double lumen tube adapter.
- To assess its utility in pediatric tracheobronchial foreign body removal.
Main Methods:
- 35 children with tracheobronchial foreign bodies underwent general anesthesia.
- A laryngeal mask airway was used with a modified Broncho-Cath Right adapter for ventilation.
- Bronchofiberscope implantation was performed for foreign body removal.
Main Results:
- Successful bronchofiberscope implantation was achieved in 91% of patients.
- Significant improvements in oxygenation (PaO2) were observed.
- Higher incidences of complications were noted in patients with higher ASA scores (III/IV).
Conclusions:
- The modified Broncho-Cath Right adapter and laryngeal mask airway enhance ventilation and perioperative safety.
- This approach is a viable option for pediatric tracheobronchial foreign body removal.
- The technique demonstrates clinical applicability and potential benefits.
Objective:
To explore the safety and effectiveness of modified adapter of Broncho-Cath(TM) Right double lumen tube in removal of tracheobronchial foreign bodies in children.
Methods:
General anesthesia was induced in 35 children with tracheobronchial foreign bodies. Then a laryngeal mask airway was implanted into each patient, and a modified adapter of Broncho-Cath TM Right double lumen tube was connected for intermittent positive-pressure ventilation.
Results:
4, 21 and 10 children suffered from intratracheal foreign body, left main bronchial foreign body and right main endobronchial foreign body, respectively. Bronchofiberscope implantation was satisfactorily achieved in 32 children (91%), and success in bronchofiberscope was successfully implanted after adjustment in 3 children (9%). Compared to T0, HR decreased at T1 (P < 0.05) and significantly reduced at T2, T3 and T4 (P < 0.01). MAP increased at T1 and declined at T3 (P < 0.05). PaO2 rose significantly at T1~T5 (P < 0.01), and there were no statistical differences in PaCO2 at different time points. Compared to ASA II patients, the incidences of severe hypoxemia, hypertension or hypotension were all higher, and the awakening time was longer in ASA III or IV patients (P < 0.05), and the bronchoscopy time was longer and the incidence of arrhythmia was significantly higher (P < 0.01).
Conclusion:
In removal of tracheobronchial foreign bodies in children, appropriately modified Broncho-Cath(TM) Right adapter and laryngeal mask airway after intravenous anesthesia for breathing control can improve the ventilation function and perioperative safety. Thereby, it is worthy of clinical application.
