Insights
Pressure controlled ventilation and high-frequency jet ventilation show similar effectiveness for pediatric tracheobronchial foreign body removal. Both methods are safe and comparable, with pressure controlled ventilation being a viable clinical option.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Respiratory Medicine
Context:
- Tracheobronchial foreign body aspiration is a common pediatric emergency.
- Ventilatory strategies significantly impact outcomes during airway foreign body removal.
- Evaluating different ventilation modes is crucial for optimizing patient safety and procedure efficiency.
Purpose:
- To compare the efficacy and safety of pressure controlled ventilation (PCV) versus high-frequency jet ventilation (HFJV) for pediatric tracheobronchial foreign body removal.
- To assess perioperative outcomes, including arterial blood gas levels, hypoxia, procedure duration, and emergence time.
Summary:
- A randomized study involving 90 children (10 months to 3 years) compared PCV, HFJV, and spontaneous breathing for foreign body removal.
- Post-operative arterial blood gas analysis revealed significantly higher PaO₂ and lower PaCO₂ in the HFJV group.
- No significant differences were observed in hypoxia occurrence, procedure duration, anesthesia emergence, or perioperative side effects between PCV and HFJV groups.
Impact:
- Both PCV and HFJV are effective and safe ventilatory methods for pediatric tracheobronchial foreign body removal.
- PCV presents a practical and widely applicable alternative for this procedure in pediatric patients.
- Findings support the routine clinical use of PCV in managing pediatric airway foreign bodies.
Abstract:
Objective:To evaluate the effects of pressure controlled ventilation for tracheobronchial foreign body removal in children.Method: Ninety ASAⅡor Ⅲ children,aged 10 months to 3 yr,weighing 8-16 kg undergoing removal of airway foreign body were randomly divided into 3 groups(n=30 each):groupⅠpressure controlled ventilation(P),group Ⅱ high-frequency jet ventilation(H),and group Ⅲ, reserve spontaneously breathings.Arterial blood gas analysis of Pre-operation and the end of operation,the occurrence of hypoxia during operation,the duration of operation,anesthesia emergence time and perioperative side effects were recorded. Result:The arterial blood gas analysis(PaO₂,PaCO₂,SaO₂)and SPO₂of Pre-operation in group P and H had no significant difference. The PaO₂ of the end of operations was significantly higher,and PaCO₂ was lower in group H. The occurrence of hypoxia during operation, the duration of operation,anesthesia emergence time and perioperative side effects in two group had no significant difference.Conclusion:The effects of pressure controlled ventilation and high-frequency jet ventilation for tracheobronchial foreign body removal in children were nearly the same,and pressure controlled ventilation can be commonly used in clinic.
