To compare the safety of laryngeal mask airway (LMA) versus face mask (FM) ventilation during induction and emergence in pediatric rigid bronchoscopy.
Key Findings:
LMA group had lower rates of laryngospasm (4.3% vs. 36.8%) and hypoxemia (8.7% vs. 42.1%).
Induction was more efficient with LMA, showing shorter durations of high-dose sevoflurane and fresh gas flow.
No significant differences in lowest SpO₂, emergence time, PACU stay, and hemodynamics.
Interpretation:
The use of LMA during induction and emergence significantly reduces airway complications compared to FM, enhancing safety in pediatric rigid bronchoscopy.
Limitations:
Small sample size with only 46 randomized participants.
Single-center study may limit generalizability.
Conclusion:
LMA is a safer alternative to FM for managing induction and emergence in pediatric rigid bronchoscopy, reducing the risk of laryngospasm and hypoxemia.
