DuoVent Endobronchial Tube Single Lung Ventilation in Pediatric Patients
Student Team: Lungevity
Humphrey Lam, MD, Children’s Healthcare of Atlanta
In pediatric anesthesia, there is no single device that provides single lung ventilation (SLV) in patients under eight years of age. There are upwards of one-hundred and fifty cases per pediatric anesthesiologist each year that require single lung ventilation. Single Lung Ventilation refers to the process of inhibiting airflow to one lung allowing for collapse while the other lung remains fully ventilated to ensure proper oxygenation. It is necessary to use SLV to isolate one lung when there is a critical threat to the other lung’s functionality due to illness, acute injury, or during surgical procedures to remove all or a portion of the lung. The current solutions for patients under eight are not reliable, intuitive, streamlined, or cost-effective options. The gold standard for this procedure, the Double Lumen, does not come in sizing small enough for this subset of pediatric patients. Anesthesiologists currently use several devices in conjunction, which not only risk dislodgement and unsecure airways but are not placed in a time-efficient manner. The DuoVent Pediatric Endobronchial Tube offers a one-step, secure, seamless intubation in a 4.5mm size for ages four to six years old. Conceived through careful consideration of the delicate patient population, current intubation practice, and user feedback from pediatric anesthesiologists, critical care nurses, otolaryngologists, and clinical engineers, the DuoVent provides a simple, single rotating mechanism to either supply or restrict air flow to the operative lung. These features will reduce time spent securing the airway with an inadequate device in the single lung ventilation procedure. Additionally, the intubation and placement procedure of the DuoVent would not vary from the current practice of direct laryngoscopy. The DuoVent holds promising potential to break into the endobronchial market through providing an effective and simplified solution for pediatric single lung ventilation.
