Selective bronchial intubation for one-lung ventilation and independent-lung ventilation in pediatric age: state of
Insights
Selective bronchial intubation (SBI) using double-lumen tubes (DLTs) or bronchial blockers is crucial for pediatric one-lung ventilation (OLV) and independent-lung ventilation (ILV). Operator experience is key to minimizing complications like airway trauma and hypoxia.
Area of Science:
- Pediatric Anesthesiology
- Respiratory Care
- Thoracic Surgery
Background:
- Selective bronchial intubation (SBI) for one-lung ventilation (OLV) and independent-lung ventilation (ILV) is vital in pediatric anesthesia for thoracic surgery and critical care.
- Current double-lumen tubes (DLTs) are suitable for children over 6-8 years, but options for younger children are limited, with a specialized device available only as a special order.
Purpose of the Study:
- To review the available methods for selective bronchial intubation (SBI) in pediatric patients.
- To discuss the application and limitations of double-lumen tubes (DLTs) and bronchial blockers for OLV and ILV in different pediatric age groups.
- To highlight potential complications associated with these devices and procedures.
Main Methods:
- Review of current literature and devices for pediatric selective bronchial intubation.
- Discussion of the use of double-lumen tubes (DLTs) and bronchial blockers.
- Analysis of age-specific applications and limitations.
Main Results:
- Double-lumen tubes (DLTs) are preferred for OLV and ILV in children over 6-8 years.
- Bronchial blockers serve as an alternative for SBI and OLV when DLTs are unavailable.
- Conventional single-lumen tubes can achieve SBI but not ILV.
- A specialized pediatric DLT for ILV exists but is not widely available.
Conclusions:
- Effective pediatric selective bronchial intubation requires careful device selection based on age and intended ventilation strategy (OLV vs. ILV).
- Operator experience significantly impacts the safety and success of SBI, with potential complications including airway trauma and hypoxia.
- Further development and availability of specialized devices are needed for younger pediatric patients requiring ILV.
Abstract:
Selective bronchial intubation (SBI) to ventilate a single lung (one-lung ventilation, OLV) or to apply separate lung ventilation (independent-lung ventilation, ILV) can be frequently required under general anesthesia in pediatrics, mainly in video assisted thoracoscopy surgery, in the postoperative care of cardio-thoracic surgery, and for the treatment of lung pathologies with unilateral prevalence in intensive care. In children over 6-8 years of age SBI, OLV and ILV can be performed using marketed double-lumen tubes (DLTs). In neonates, infants and younger children the application of ILV is limited due to the lack of DLTs. For children of this age, a specific DLT for ILV was developed (Marraro Paediatric Endobronchial Bilumen Tube®) but is currently available only as a special product. The DLT represents the device of choice for OLV and ILV while the use of bronchial blocker is suggested as an alternative to achieve the SBI and the OLV when suitable DLTs are not available. Different catheters types can be used as bronchial blocker. If SBI is not possible using DLT or bronchial blocker, a conventional single-lumen tube of adequate length can allow SBI in all pediatric ages. Using the bronchial blocker and single lumen tube it is possible to perform OLV but it is impossible to apply ILV. The main complications of SBI and DLT are largely due to limited operator experience. Airway trauma, dislodgment and obstruction of the devices are quite frequent and can lead to severe hypoxia if not recognized and treated early.
